CBCS — Certified Billing and Coding Specialist — Questions and Answers
Question 1: What should a billing specialist do when a prior authorization is approved but expires before the service is rendered?
- Obtain a new or extended authorization before the service is rendered (Correct answer)
- Bill the patient directly for the service
- Proceed with the service and appeal if denied
- Use the expired authorization number on the claim
Correct answer: Obtain a new or extended authorization before the service is rendered
If a prior authorization expires before the service is performed, a new or extended authorization must be obtained to ensure coverage.
Question 2: What is the purpose of a patient intake form during registration?
- To create the superbill
- To assign ICD-10 codes
- To collect medical history, insurance data, and demographic information needed for billing and care (Correct answer)
- To determine the patient's payment plan
Correct answer: To collect medical history, insurance data, and demographic information needed for billing and care
The patient intake form gathers demographics, insurance details, and medical history to support accurate billing, coding, and clinical care.
Question 3: What is a Certificate of Creditable Coverage and why is it relevant to billing?
- A document certifying that a provider is credentialed with an insurance network
- A certification that a claim has been reviewed and approved by the insurer
- A document required when billing for experimental or investigational procedures
- A document from a prior health plan confirming the length of previous creditable coverage, which can reduce pre-existing condition waiting periods under some plans (Correct answer)
Correct answer: A document from a prior health plan confirming the length of previous creditable coverage, which can reduce pre-existing condition waiting periods under some plans
A Certificate of Creditable Coverage documents a patient's prior continuous health insurance coverage. Under pre-ACA rules, it could reduce waiting periods for pre-existing condition exclusions under new employer group plans.
Question 4: What is the Stark Law (Physician Self-Referral Law) designed to prevent?
- Physicians from referring patients to entities with which they have a financial relationship, unless an exception applies (Correct answer)
- Physicians from billing more than the Medicare fee schedule
- Physicians from accepting insurance from plans in which they are not contracted
- Physicians from practicing in multiple states without proper licensure
Correct answer: Physicians from referring patients to entities with which they have a financial relationship, unless an exception applies
The Stark Law prohibits physicians from referring Medicare/Medicaid patients to entities for designated health services if the physician or an immediate family member has a financial relationship with that entity.
Question 5: A patient's insurance card shows a group number and member ID. What is the group number used for?
- Determining the patient's deductible amount
- Authorizing a referral
- Identifying the employer-sponsored plan (Correct answer)
- Identifying the individual patient
Correct answer: Identifying the employer-sponsored plan
The group number identifies the employer or group plan sponsor under which the patient's coverage is provided, while the member ID identifies the individual.
Question 6: Which government agency is responsible for enforcing HIPAA Privacy and Security Rules?
- CMS
- OIG
- OCR (HHS Office for Civil Rights) (Correct answer)
- CDC
Correct answer: OCR (HHS Office for Civil Rights)
The HHS Office for Civil Rights (OCR) is the primary enforcer of HIPAA Privacy and Security Rules.
Question 7: A patient with a Preferred Provider Organization (PPO) plan chooses to see a specialist who is not in the PPO network. Which of the following outcomes is most likely?
- The insurance plan will deny the claim entirely because the provider is out-of-network.
- The patient must first get a referral from their PCP for the services to be covered.
- The patient's services will be covered at the same rate as an in-network provider.
- The patient will likely have a higher coinsurance or copayment and a separate, higher deductible for out-of-network services. (Correct answer)
Correct answer: The patient will likely have a higher coinsurance or copayment and a separate, higher deductible for out-of-network services.
PPO plans offer members the flexibility to see out-of-network providers. However, this flexibility typically comes at a higher cost to the patient in the form of increased cost-sharing responsibilities (copayments, coinsurance, and deductibles) compared to using in-network providers.
Question 8: What is a HIPAA breach and what are the notification requirements?
- Any unauthorized viewing of PHI by a non-clinical staff member, requiring immediate patient notification
- An impermissible acquisition, access, use, or disclosure of PHI that compromises its security or privacy, requiring notifications to individuals, HHS, and potentially the media (Correct answer)
- Only a cyberattack that exposes ePHI to external hackers, requiring law enforcement notification
- Any accidental mailing of a bill to the wrong address, requiring no notification
Correct answer: An impermissible acquisition, access, use, or disclosure of PHI that compromises its security or privacy, requiring notifications to individuals, HHS, and potentially the media
A HIPAA breach is an impermissible use or disclosure of unsecured PHI that is presumed to be a breach unless a risk assessment shows low probability that PHI was compromised. Notification to affected individuals, HHS, and (for large breaches) media is required.
Question 9: When coding a fracture in ICD-10-CM, what information is needed to select the correct 7th character?
- The encounter type (initial, subsequent, sequela), healing status for subsequent encounters, and for open fractures, the Gustilo classification (Correct answer)
- The patient's age and whether surgery was performed
- Only whether the fracture is complete or incomplete
- Only the bone that was fractured and the fracture type
Correct answer: The encounter type (initial, subsequent, sequela), healing status for subsequent encounters, and for open fractures, the Gustilo classification
Fracture coding requires the 7th character to reflect: (1) whether it is an initial encounter (A=closed, B=open type I/II, C=open type IIIA/B/C), (2) subsequent encounter healing status (D=routine, G=delayed, K=nonunion, P=malunion), or (3) sequela (S).
Question 10: Which section of CPT covers anesthesia services?
- 10004–69990
- 90281–99199
- 00100–01999 (Correct answer)
- 70010–79999
Correct answer: 00100–01999
CPT codes 00100–01999 cover anesthesia services.
Question 11: Which of the following best describes the concept of 'minimum necessary' under HIPAA?
- Patients must provide only the minimum required consent for treatment
- Covered entities must use or disclose only the minimum amount of PHI needed to accomplish the intended purpose (Correct answer)
- Healthcare providers must collect the least amount of patient information possible at registration
- Insurance companies must pay at least the minimum required reimbursement
Correct answer: Covered entities must use or disclose only the minimum amount of PHI needed to accomplish the intended purpose
The minimum necessary standard requires covered entities to make reasonable efforts to limit PHI use and disclosure to what is necessary to accomplish the intended purpose.
Question 12: In medical documentation, 'acute' vs. 'chronic' affects ICD-10-CM coding because:
- Only chronic conditions are coded
- Chronicity is not coded
- They share the same code
- They have different code assignments (Correct answer)
Correct answer: They have different code assignments
Acute and chronic forms of the same condition often have different ICD-10-CM codes, so accurate documentation of disease duration is essential for correct coding.
Question 13: What does the term 'accounts receivable (AR)' represent in medical billing?
- Amounts owed to vendors by the practice
- Money the practice has already collected
- Money owed to the practice for services rendered but not yet paid (Correct answer)
- The total charges generated in a billing period
Correct answer: Money owed to the practice for services rendered but not yet paid
Accounts receivable (AR) represents the total amount owed to a healthcare provider for services already rendered but not yet paid by payers or patients.
Question 14: Which standard transaction code set is used for submitting pharmacy claims electronically?
- 270/271
- 837P
- NCPDP Telecom Standard (Correct answer)

Question 16: Which registration form obtains the patient's permission for treatment and acknowledges their financial responsibility?
- HIPAA Privacy Notice
- ABN
- Assignment of benefits
- Patient consent and financial responsibility form (Correct answer)
Correct answer: Patient consent and financial responsibility form
The patient consent and financial responsibility form obtains consent for treatment and informs the patient they are responsible for any unpaid balances.
Question 17: What does the prefix 'brady-' mean in medical terminology?
- Small
- Fast
- Large
- Slow (Correct answer)
Correct answer: Slow
The prefix 'brady-' means slow, as in bradycardia (slow heart rate).
Question 18: What is the primary purpose of the AHIMA and AAPC codes of ethics for medical coders?
- To set billing rates for coding services
- To guide professional conduct, ensure accurate coding, and protect patient privacy (Correct answer)
- To determine which coding credentials are most valuable
- To establish continuing education requirements
Correct answer: To guide professional conduct, ensure accurate coding, and protect patient privacy
Professional codes of ethics for coders emphasize accurate and complete coding, protecting patient confidentiality, avoiding fraud, and maintaining professional competence.
Question 19: What is the significance of the 'group number' on an insurance card?
- It identifies the patient's primary care physician within the plan network
- It is the patient's individual member identification number
- It indicates the insurance company's local branch office
- It identifies the specific plan design and benefits package associated with an employer's group contract with the insurance company (Correct answer)
Correct answer: It identifies the specific plan design and benefits package associated with an employer's group contract with the insurance company
The group number on an insurance card identifies the employer's group contract with the insurance plan, linking the patient to their specific employer-sponsored benefit package and coverage terms.
Question 20: In ICD-10-CM, what does the 7th character extension 'A' typically indicate?
- Sequela
- Subsequent encounter
- Active treatment phase
- Initial encounter (Correct answer)
Correct answer: Initial encounter
In ICD-10-CM, the 7th character 'A' designates an initial encounter — the active phase of treatment when the patient is receiving definitive care for the condition.
Question 21: What is a denial trend analysis and why is it important?
- A review of patient complaints about billing practices
- An analysis of how often providers change their fee schedules
- An analysis of how long claims take to be paid
- Identifying patterns in claim denials by reason code, payer, or service type to find and fix root causes of denials (Correct answer)
Correct answer: Identifying patterns in claim denials by reason code, payer, or service type to find and fix root causes of denials
Denial trend analysis involves tracking denials by type, payer, provider, and service to identify systemic issues. Finding root causes allows the practice to prevent denials proactively rather than just reacting to them.
Question 22: Which of the following best describes a breach of patient confidentiality?
- Sharing a patient’s health information with a family member without consent (Correct answer)
- Discussing a patient's case with authorized personnel in a secure setting
- Using patient data for research with de-identified information
- Reviewing a patient’s medical records for legitimate billing purposes
Correct answer: Sharing a patient’s health information with a family member without consent
Patient confidentiality, mandated by HIPAA, means that protected health information (PHI) cannot be disclosed without the patient's explicit authorization. Sharing a patient's health information with a family member without their consent constitutes a breach because it violates the patient's right to privacy. Authorized personnel and legitimate billing or de-identified research purposes are permissible under specific guidelines.
Question 23: What is Workers' Compensation insurance, and how does billing differ from standard health insurance?
- A federal insurance program for all injury-related medical care
- Insurance that employees purchase themselves to cover job-related injuries
- Insurance that covers medical treatment and lost wages for employees injured on the job or who develop work-related illnesses; billing uses separate forms and diagnosis coding specific to the injury (Correct answer)
- Insurance for employers to cover their liability if an employee injures a patient
Correct answer: Insurance that covers medical treatment and lost wages for employees injured on the job or who develop work-related illnesses; billing uses separate forms and diagnosis coding specific to the injury
Workers' compensation covers medical care and lost wages for work-related injuries/illnesses. Claims are billed to the employer's WC carrier using state-specific forms, focus only on the work injury, and follow different reimbursement rules than standard health insurance.
Question 24: What should a billing specialist do if they discover a significant billing error that could affect reimbursement?
- Notify the insurance company immediately about the error and request an adjustment (Correct answer)
- Correct the error and resubmit the claim without notifying the insurance company
- Ignore the error if it benefits the practice financially
- Wait for the insurance company to identify the error before taking any action
Correct answer: Notify the insurance company immediately about the error and request an adjustment
Ethical billing practices require transparency and honesty. If a significant billing error is discovered, the billing specialist must immediately notify the insurance company to correct the claim. This ensures compliance with regulations, prevents potential fraud accusations, and maintains the integrity of the billing process.
Question 25: A physician performs a diagnostic colonoscopy that becomes therapeutic when a polyp is removed. How should this be coded?
- Code the diagnostic with modifier -52 and the therapeutic separately
- Code only the therapeutic colonoscopy (Correct answer)
- Code both diagnostic and therapeutic colonoscopy with modifier -59
- Code only the diagnostic colonoscopy
Correct answer: Code only the therapeutic colonoscopy
When a diagnostic procedure becomes therapeutic, only the therapeutic (more extensive) code is reported.
Question 26: What is a self-funded (self-insured) employer health plan?
- An employer that provides health benefits funded entirely by employee payroll deductions
- An employer that assumes financial responsibility for employee health claims rather than paying premiums to an insurance company; typically administered by a TPA (Correct answer)
- An employer that purchases a standard insurance policy from an insurer
- A small employer that qualifies for a government subsidy to fund health benefits
Correct answer: An employer that assumes financial responsibility for employee health claims rather than paying premiums to an insurance company; typically administered by a TPA
In a self-funded plan, the employer directly pays employee health claims from its own funds rather than buying insurance. A Third-Party Administrator (TPA) typically processes claims using the employer's money.
Question 27: Which chapter in ICD-10-CM contains codes for external causes of morbidity?
- Chapter 20 (Correct answer)
- Chapter 19
- Chapter 21
- Chapter 18
Correct answer: Chapter 20
Chapter 20 (V00–Y99) contains codes for external causes of morbidity.
Question 28: A practice's billing manager is analyzing denial trends to identify areas for improvement. Which of the following denial reasons points to a preventable error that should be addressed by front-desk staff during patient registration and check-in?
- Claim denied for exceeding the timely filing limit.
- Service not covered under the patient's benefit plan.
- Patient's insurance coverage was terminated prior to the date of service. (Correct answer)
- Procedure determined to be not medically necessary.
Correct answer: Patient's insurance coverage was terminated prior to the date of service.
A denial due to terminated insurance coverage is a classic example of a preventable denial that can be caught by robust front-end processes. Verifying eligibility and benefits in real-time before or at the time of service would have identified that the patient's coverage was not active, allowing the office to make other financial arrangements.
Question 29: What is the difference between Medicare Advantage (Part C) and Original Medicare?
- Medicare Advantage is only available in rural areas; Original Medicare covers urban areas
- Medicare Advantage is a private plan alternative to Original Medicare that includes Part A and Part B benefits, often with additional coverage; Original Medicare is administered directly by the federal government (Correct answer)
- Medicare Advantage requires a referral for all services; Original Medicare allows open access to any provider
- Medicare Advantage covers only prescription drugs; Original Medicare covers hospitalization
Correct answer: Medicare Advantage is a private plan alternative to Original Medicare that includes Part A and Part B benefits, often with additional coverage; Original Medicare is administered directly by the federal government
Medicare Advantage (Part C) plans are offered by private insurers approved by Medicare. They include all Part A and Part B benefits and often add dental, vision, hearing, and prescription drug coverage. Original Medicare is the traditional fee-for-service program run by CMS.
Question 30: What is Medicaid?
- A supplemental coverage plan for Medicare beneficiaries
- A federal health insurance program for individuals age 65 and older
- A joint federal-state program providing health coverage to low-income individuals and families (Correct answer)
- A private insurance option for small businesses
Correct answer: A joint federal-state program providing health coverage to low-income individuals and families
Medicaid is a joint federal-state program that provides health coverage to eligible low-income adults, children, pregnant women, elderly adults, and people with disabilities.
Question 31: What is a National Coverage Determination (NCD)?
- A state-level insurance mandate requiring coverage of specific conditions
- A coverage decision made by a commercial insurer for its subscriber population
- A CMS policy determining whether a service, item, or procedure is covered nationally under Medicare, binding on all MACs and Medicare Advantage plans (Correct answer)
- A determination made by a provider as to whether a service is medically necessary
Correct answer: A CMS policy determining whether a service, item, or procedure is covered nationally under Medicare, binding on all MACs and Medicare Advantage plans
An NCD is a national Medicare coverage policy issued by CMS that determines whether a specific medical service is covered, covered with conditions, or non-covered for all Medicare beneficiaries nationwide.
Question 32: A patient is seen in the clinic and the provider's final diagnosis is 'acute bronchitis caused by Mycoplasma pneumoniae.' Which is the correct ICD-10-CM code assignment?
- J20.9
- J40, B96.0
- J20.0 (Correct answer)
- J20.9, B96.0
Correct answer: J20.0
The ICD-10-CM Alphabetic Index under 'Bronchitis, acute or subacute, due to, Mycoplasma pneumoniae,' directs the coder to J20.0. This is a combination code that captures both the condition (acute bronchitis) and the causative organism, making it unnecessary and incorrect to code them separately.
Question 33: Which CPT modifier indicates a procedure was performed bilaterally?
- -50 (Correct answer)
- -51
- -52
- -53
Correct answer: -50
Modifier -50 is used to indicate that a procedure was performed bilaterally during the same operative session.
Question 34: Which form is also known as the CMS-1450?
- UB-04 (Correct answer)
- UB-92
- CMS-1500
- HCFA-1500
Correct answer: UB-04
The UB-04 claim form, also known as the CMS-1450, is the standardized form used by institutional providers, such as hospitals, to bill for inpatient and outpatient services. It is distinct from the CMS-1500, which is used by professional providers. The UB-04 captures comprehensive information about facility charges and patient demographics.
Question 35: What is a principal diagnosis in inpatient hospital coding?
- The condition that was present on admission (POA)
- The first diagnosis code entered on the UB-04
- The most severe diagnosis listed on the claim
- The condition established after study to be chiefly responsible for the admission of the patient to the hospital (Correct answer)
Correct answer: The condition established after study to be chiefly responsible for the admission of the patient to the hospital
The principal diagnosis is defined as the condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital for care.
Question 36: What information is contained in Box 33 of the CMS-1500 claim form?
- The date and place of service
- The referring physician's name and NPI
- The billing provider's name, address, phone number, and NPI (Correct answer)
- The patient's diagnosis codes
Correct answer: The billing provider's name, address, phone number, and NPI
Box 33 contains the billing provider's (or group practice's) name, address, phone number, and NPI — the entity responsible for submitting the claim and receiving payment.
Question 37: What is the purpose of an Advance Beneficiary Notice (ABN) in Medicare billing?
- To document that a Medicare beneficiary has chosen a specific Medicare Advantage plan
- To notify Medicare before a beneficiary is admitted to a hospital
- To authorize a Medicare beneficiary to appeal a denial on their own behalf
- To inform a Medicare beneficiary that a service may not be covered by Medicare so they can decide whether to receive the service and accept financial responsibility (Correct answer)
Correct answer: To inform a Medicare beneficiary that a service may not be covered by Medicare so they can decide whether to receive the service and accept financial responsibility
An ABN is a written notice given to a Medicare beneficiary before a service is provided when the provider believes Medicare may not cover the service, allowing the patient to make an informed financial decision.
Question 38: What is the key coding difference between inpatient and outpatient settings for uncertain diagnoses?
- Both settings prohibit coding uncertain diagnoses
- Outpatient allows coding uncertain diagnoses; inpatient does not
- Inpatient allows coding uncertain diagnoses as if confirmed; outpatient requires coding only signs and symptoms (Correct answer)
- Both settings allow coding uncertain diagnoses with a modifier
Correct answer: Inpatient allows coding uncertain diagnoses as if confirmed; outpatient requires coding only signs and symptoms
In inpatient coding, 'probable,' 'suspected,' and 'likely' diagnoses may be coded as confirmed. In outpatient coding, only confirmed diagnoses or signs/symptoms are coded.
Question 39: HCPCS Level II 'V codes' are used primarily for which types of services and supplies?
- Vision, hearing, and speech-language pathology services and supplies (Correct answer)
- Vascular surgical procedures
- Vaccines and immunization administration
- Ventilation and respiratory equipment
Correct answer: Vision, hearing, and speech-language pathology services and supplies
V codes (V0000–V2999) cover vision items such as eyeglasses and contact lenses, hearing items, and speech-language pathology services.
Question 40: What are patients' rights under the HIPAA Privacy Rule?
- Rights including access to their PHI, request for amendments, accounting of disclosures, right to restrict certain uses/disclosures, and right to receive confidential communications (Correct answer)
- The right to have all their medical bills forgiven if information is disclosed without permission
- The exclusive right to decide who can access their complete medical record, with no exceptions
- The right to have all of their PHI destroyed upon request
Correct answer: Rights including access to their PHI, request for amendments, accounting of disclosures, right to restrict certain uses/disclosures, and right to receive confidential communications
The HIPAA Privacy Rule gives patients specific rights: access their health records, request corrections (amendments), obtain an accounting of certain disclosures, request restrictions on use/disclosure, and receive confidential communications.
Question 41: Why is it important to verify insurance eligibility for established patients, not just new patients?
- It is only necessary for new patients; established patients' insurance never changes
- Insurance coverage can change due to job changes, open enrollment, aging off a parent's plan, or COBRA expiration — verifying at each visit prevents claim denials (Correct answer)
- It is required by law to verify established patients' eligibility at every visit
- Established patients are more likely to be fraudulent claimants
Correct answer: Insurance coverage can change due to job changes, open enrollment, aging off a parent's plan, or COBRA expiration — verifying at each visit prevents claim denials
Insurance coverage is not static — it changes frequently due to employment changes, life events, plan changes during open enrollment, and coverage terminations. Verifying at each encounter prevents billing errors and denials.
Question 42: Under HIPAA, which of the following is a covered entity?
- A marketing firm that analyzes patient data for a hospital
- A software company that builds EHR systems
- An employer who sponsors a health plan
- A health plan that pays for medical services (Correct answer)
Correct answer: A health plan that pays for medical services
Health plans are covered entities under HIPAA, along with healthcare providers and healthcare clearinghouses.
Question 43: What is the consequence of billing for a service that required prior authorization but was not obtained?
- The payer pays at a reduced rate automatically
- The claim is automatically resubmitted with a corrected authorization
- The claim will likely be denied, and the provider may not be able to bill the patient (Correct answer)
- The patient is responsible for the full cost of the service
Correct answer: The claim will likely be denied, and the provider may not be able to bill the patient
Claims without required prior authorization are typically denied, and in many contracts, the provider cannot balance-bill the patient for the denied amount.
Question 44: What is the difference between a 'subscriber' and a 'dependent' in health insurance?
- A subscriber is the patient; a dependent is the patient's physician
- A subscriber is the individual who enrolls in and is primarily covered by the insurance policy; a dependent is a family member (spouse, child) covered under the subscriber's plan (Correct answer)
- There is no practical billing difference between subscriber and dependent
- A subscriber pays higher premiums; dependents pay lower premiums
Correct answer: A subscriber is the individual who enrolls in and is primarily covered by the insurance policy; a dependent is a family member (spouse, child) covered under the subscriber's plan
The subscriber (or policyholder) is the person who enrolled in the health plan, often through an employer. Dependents are family members who receive coverage under the subscriber's policy.
Question 45: What is the HIPAA Security Rule's requirement for electronic PHI (ePHI)?
- ePHI must be stored only on servers within the United States
- Covered entities must implement administrative, physical, and technical safeguards to ensure the confidentiality, integrity, and availability of ePHI (Correct answer)
- ePHI must be encrypted using AES-256 encryption at all times
- ePHI access must be limited to licensed healthcare providers only
Correct answer: Covered entities must implement administrative, physical, and technical safeguards to ensure the confidentiality, integrity, and availability of ePHI
The Security Rule requires covered entities and business associates to implement three types of safeguards — administrative, physical, and technical — to protect ePHI from unauthorized access, use, or disclosure.
Question 46: What does 'meaningful use' of an EHR require?
- Using certified EHR technology in ways that improve quality, safety, and efficiency (Correct answer)
- Adopting an EHR approved by the state government
- Using an EHR system at least once per week
- Using EHRs only for billing and coding purposes
Correct answer: Using certified EHR technology in ways that improve quality, safety, and efficiency
Meaningful use requires healthcare providers to use certified EHR technology in specific, measurable ways to improve patient care.
Question 47: What does 'coordination of benefits (COB) information' need to be confirmed during eligibility verification for a patient with two insurance plans?
- Only whether both plans cover the planned services
- Which plan is primary (pays first), which is secondary, and whether the plans coordinate to prevent duplicate payment (Correct answer)
- Whether the patient has met both plans' deductibles
- Whether the patient prefers to use their primary or secondary insurance
Correct answer: Which plan is primary (pays first), which is secondary, and whether the plans coordinate to prevent duplicate payment
COB verification confirms the payment order — which plan is primary and which is secondary — and ensures proper billing sequence to comply with both plans' requirements and maximize claim payment.
Question 48: What is the 'two-midnight rule' under Medicare?
- Any stay lasting more than two midnights is automatically paid as inpatient
- A physician must expect a patient's stay to cross two midnights for inpatient admission to be medically necessary under Medicare (Correct answer)
- Hospital discharge decisions must be made before midnight on the second day
- Patients must be in observation for at least two midnights before inpatient admission
Correct answer: A physician must expect a patient's stay to cross two midnights for inpatient admission to be medically necessary under Medicare
CMS's two-midnight rule states that inpatient admission is appropriate when the treating physician expects the patient to require hospital care spanning at least two midnights.
Question 49: What is a Business Associate Agreement (BAA) under HIPAA?
- A consent form signed by patients authorizing their information to be shared with third parties
- A written contract between a covered entity and a business associate that specifies permitted uses of PHI and requires the business associate to protect PHI (Correct answer)
- A contract between an insurance company and a healthcare provider specifying reimbursement rates
- An agreement between two competing healthcare providers not to share patient information
Correct answer: A written contract between a covered entity and a business associate that specifies permitted uses of PHI and requires the business associate to protect PHI
A BAA is a legally required contract between a covered entity and any business associate who may access, use, or disclose PHI in the course of performing services. It specifies permitted uses and requires appropriate safeguards.
Question 50: What is the timely filing limit for Medicare claims?
- 2 years from date of service
- 90 days from date of service
- 6 months from date of service
- 1 year (12 months) from date of service (Correct answer)
Correct answer: 1 year (12 months) from date of service
Medicare requires claims to be filed within 12 months (1 calendar year) from the date of service. Claims submitted after this deadline will be denied for timely filing.
Question 51: What is a charge master (CDM) and how does it relate to billing?
- A database of all payer contracts and their reimbursement rates
- A comprehensive list of all services, procedures, supplies, and their associated charges used by a facility to generate patient bills and insurance claims (Correct answer)
- A master list of all credentialed providers in a health system and their billing rates
- A master schedule for all billing staff work assignments
Correct answer: A comprehensive list of all services, procedures, supplies, and their associated charges used by a facility to generate patient bills and insurance claims
The charge master (CDM) is a healthcare facility's comprehensive price list containing every billable item (services, procedures, supplies, drugs) with associated CDM codes, revenue codes, CPT/HCPCS codes, and charge amounts.
Question 52: What is the primary purpose of HCPCS Level II codes in medical billing?
- To document patient demographic and insurance information
- To report supplies, equipment, and services not adequately described by CPT codes (Correct answer)
- To replace ICD-10-CM diagnosis codes for outpatient claims
- To identify the ordering physician on a claim
Correct answer: To report supplies, equipment, and services not adequately described by CPT codes
HCPCS Level II codes fill the gap left by CPT codes by reporting supplies, equipment, drugs, and other services—particularly for Medicare and Medicaid claims.
Question 53: What is a Clinical Documentation Improvement (CDI) specialist's primary role in inpatient coding?
- To assign final ICD-10-CM and ICD-10-PCS codes to inpatient records
- To train coders on updated coding guidelines
- To audit completed records for compliance errors
- To query physicians to clarify documentation and capture the full complexity of the patient's condition (Correct answer)
Correct answer: To query physicians to clarify documentation and capture the full complexity of the patient's condition
CDI specialists review inpatient records concurrently and query physicians to ensure documentation is complete, accurate, and supports the appropriate level of coding.
Question 54: What does 'Medigap' (Medicare Supplement Insurance) cover?
- Dental, vision, and hearing services excluded from Original Medicare
- Out-of-pocket costs associated with Original Medicare, such as deductibles, copays, and coinsurance, sold by private insurance companies (Correct answer)
- Prescription drugs not covered by Medicare Part B
- Services that Medicare considers experimental or investigational
Correct answer: Out-of-pocket costs associated with Original Medicare, such as deductibles, copays, and coinsurance, sold by private insurance companies
Medigap plans are standardized supplemental insurance policies sold by private insurers that help pay the patient's share of Original Medicare costs (deductibles, coinsurance, copays).
Question 55: A physician orders a hemoglobin A1c test for a diabetic patient's routine monitoring. What code set is used to report this lab service?
- Revenue codes
- HCPCS Level II
- ICD-10-PCS
- CPT (85018 or 83036) (Correct answer)
Correct answer: CPT (85018 or 83036)
Lab services such as hemoglobin A1c are reported using CPT codes from the Pathology and Laboratory section.
Question 56: What is the CMS-1500 claim form primarily used for?
- To submit claims for hospital inpatient services
- To document patient medical history
- To enroll patients in insurance plans
- To submit claims for outpatient and professional services (Correct answer)
Correct answer: To submit claims for outpatient and professional services
The CMS-1500 claim form is the universal claim form used by non-institutional providers, such as physicians, therapists, and suppliers, to bill for outpatient and professional services. It is essential for submitting claims to Medicare, Medicaid, and most private insurance companies. This standardized form ensures consistent reporting of services and charges.
Question 57: What is the correct action when a patient's name on the insurance card differs slightly from the registration system?
- Use the registration system name regardless
- Cancel the appointment
