Epic Skills Assessment Revenue Cycle and Billing 1 — Questions and Answers

Question 1: What is the 'revenue cycle' in healthcare, and what are its main components?

The end-to-end financial process from patient scheduling through payment collection, including registration, coding, billing, claims, posting, and denials management (Correct answer)
Only the billing and collections phase of healthcare finance
The process of budgeting and financial planning for a healthcare organization
The procurement and supply chain financial cycle

Correct answer: The end-to-end financial process from patient scheduling through payment collection, including registration, coding, billing, claims, posting, and denials management

The revenue cycle encompasses every step of earning and collecting revenue: patient access (scheduling, registration, eligibility), clinical documentation, charge capture, coding, claim submission, payment posting, denial management, and patient balance collections.

Question 2: What is the difference between ICD-10-CM and ICD-10-PCS codes in medical coding?

ICD-10-CM codes diagnoses (why); ICD-10-PCS codes inpatient procedures (what was done) — together they drive DRG assignment and inpatient reimbursement (Correct answer)
ICD-10-CM is for outpatient; ICD-10-PCS is for physician billing
ICD-10-CM is the current version; ICD-10-PCS is a proposed future standard
They are used by different payers with no clinical overlap

Correct answer: ICD-10-CM codes diagnoses (why); ICD-10-PCS codes inpatient procedures (what was done) — together they drive DRG assignment and inpatient reimbursement

ICD-10-CM (Clinical Modification) classifies diagnoses, symptoms, and reasons for encounter. ICD-10-PCS (Procedure Coding System) classifies inpatient procedures. Together, they are assigned by coders to drive DRG assignment and hospital inpatient payment.

Question 3: What does CPT (Current Procedural Terminology) code set describe, and who maintains it?

Medical procedures and services performed by physicians and other providers; maintained by the American Medical Association (AMA) (Correct answer)
Diagnosis codes for outpatient billing; maintained by WHO
Pharmacy billing codes; maintained by the FDA
Inpatient procedure codes; maintained by CMS

Correct answer: Medical procedures and services performed by physicians and other providers; maintained by the American Medical Association (AMA)

CPT codes (Level I HCPCS) are maintained by the AMA and describe medical, surgical, and diagnostic services. They are used on professional fee claims (CMS-1500 / 837P) and drive reimbursement for physician and outpatient services.

Question 4: What is a 'Diagnosis Related Group' (DRG), and how does it determine hospital payment?

A classification that groups inpatient cases by diagnosis, procedures, and complications into payment categories; hospitals receive a fixed payment per DRG regardless of actual costs (Correct answer)
A diagnostic category used for clinical documentation only
A group of related outpatient procedures billed together
A classification of drugs related to a specific disease group

Correct answer: A classification that groups inpatient cases by diagnosis, procedures, and complications into payment categories; hospitals receive a fixed payment per DRG regardless of actual costs

MS-DRGs (Medicare Severity Diagnosis Related Groups) classify inpatient stays by diagnoses, procedures, age, sex, and complications/comorbidities into groups with assigned payment weights. Medicare pays a fixed amount per DRG — incentivizing efficiency.

Question 5: What is 'charge capture,' and why is it important to revenue cycle integrity?

The process of documenting all billable services rendered during a patient encounter to ensure complete and accurate claim submission (Correct answer)
The collection of copayments at the point of service
The capture of all patient complaints during registration
The recording of all charges denied by insurance

Correct answer: The process of documenting all billable services rendered during a patient encounter to ensure complete and accurate claim submission

Charge capture ensures every service performed (procedures, medications, supplies, professional fees) generates a corresponding charge in the EHR/billing system. Missed charges = lost revenue; duplicate charges = overbilling compliance risk.

Question 6: What is the 'clean claim rate,' and why does it matter for revenue cycle performance?

The percentage of claims submitted that are accepted and paid without rejection or additional information requests; higher rates mean faster payment and lower rework costs (Correct answer)
The percentage of claims that pass internal audit review
The percentage of claims paid within 30 days of submission
The percentage of claims without any patient balance after insurance payment

Correct answer: The percentage of claims submitted that are accepted and paid without rejection or additional information requests; higher rates mean faster payment and lower rework costs

A clean claim is one that processes through the payer system without rejection or denial on first submission. Industry benchmark is >95% first-pass acceptance. Clean claim rate directly correlates with days in accounts receivable (A/R) and revenue cycle efficiency.

Question 7: What is a 'remittance advice' (ERA/EOB), and how is it used in revenue cycle?

A document from the payer detailing which charges were paid, denied, adjusted, or pended — used for payment posting and denial management (Correct answer)
A notice sent to patients detailing their financial responsibility
A billing statement generated by the hospital for the patient
An authorization document approving future services

Correct answer: A document from the payer detailing which charges were paid, denied, adjusted, or pended — used for payment posting and denial management

Electronic Remittance Advice (ERA / 835 transaction) is the payer's payment response explaining each claim line: amount paid, contractual adjustment, patient responsibility, and denial reason codes. Revenue cycle staff use ERAs for payment posting and denial follow-up.

Question 8: What is 'medical necessity' in the context of insurance billing?

The clinical justification that a service is reasonable, necessary, and appropriate for the diagnosis and condition, required by payers as a condition of reimbursement (Correct answer)
The minimum number of visits required by a condition protocol
The physical necessity of a medication for survival
Documentation that a procedure was performed by a licensed clinician

Correct answer: The clinical justification that a service is reasonable, necessary, and appropriate for the diagnosis and condition, required by payers as a condition of reimbursement

Payers require that services be medically necessary — appropriate for the documented diagnosis, not experimental, and meeting clinical criteria. Insufficient medical necessity documentation is one of the most common claim denial reasons.

Question 9: What does 'unbundling' in medical billing refer to, and why is it a compliance risk?

Separately billing procedure codes that should be billed as a bundled package code, artificially increasing reimbursement — a compliance violation under CCI edits and OIG guidance (Correct answer)
Separating inpatient from outpatient charges on the same claim
Billing multiple diagnoses on the same claim form
Submitting claims to multiple payers for the same service legitimately

Correct answer: Separately billing procedure codes that should be billed as a bundled package code, artificially increasing reimbursement — a compliance violation under CCI edits and OIG guidance

Unbundling is fraudulent billing: individually billing procedures that are included in (bundled with) a comprehensive code. CMS's Correct Coding Initiative (CCI) edits are designed to identify and reject unbundled claims. Intentional unbundling is healthcare fraud.

Question 10: What is the 'accounts receivable (A/R) days' metric in revenue cycle management?

The average number of days from service delivery to payment receipt; lower is better, with industry benchmark typically <50 days for hospitals (Correct answer)
The total dollar amount owed by all patients
The number of days the billing department has to submit claims
The average patient copay collection rate per day

Correct answer: The average number of days from service delivery to payment receipt; lower is better, with industry benchmark typically <50 days for hospitals

A/R days (Days in A/R) = Total A/R ÷ (Annual Revenue / 365). It measures how quickly the organization converts services into cash. Benchmark: commercial insurers typically <20-30 days; hospital overall <50 days. High A/R days indicate collection problems.

Question 11: What is a 'denial management' process in the revenue cycle?

The systematic identification, appeal, correction, and resubmission of denied claims, along with root cause analysis to prevent future denials of the same type (Correct answer)
Refusing to treat patients without insurance
The denial of provider network participation applications by insurers
Deleting denied claims from the billing system

Correct answer: The systematic identification, appeal, correction, and resubmission of denied claims, along with root cause analysis to prevent future denials of the same type

Denial management is a proactive cycle: identify denied claims by type (medical necessity, auth, coding, eligibility), correct and appeal within timely filing limits, and analyze denial patterns to address root causes upstream (documentation, pre-authorization, coding education).

Question 12: What is 'coordination of benefits' (COB), and when is it important in claims processing?

When a patient has multiple insurance plans, COB rules determine which pays first (primary) and how secondary insurance processes the remaining balance (Correct answer)
The coordination of clinical benefits between departments for a patient's care
The process of verifying that benefits are available before scheduling
Coordinating employee benefits between HR and payroll systems

Correct answer: When a patient has multiple insurance plans, COB rules determine which pays first (primary) and how secondary insurance processes the remaining balance

When a patient has two or more insurance plans, COB prevents overpayment to providers. The primary insurer pays first according to COB rules (birthday rule for dependents, Medicare vs. commercial primary rules). The secondary insurer covers remaining eligible amounts up to 100% of the provider's charges.

Question 13: What is a 'charge master' (CDM), and why is it important to hospital revenue cycle?

The comprehensive catalog of all hospital services with associated charge codes and standard prices, used as the starting point for claim generation (Correct answer)
A list of the hospital's highest-cost procedures for financial planning
The master list of all physician billing codes used by hospital-employed providers
A table of Medicare fee schedule allowable amounts by service

Correct answer: The comprehensive catalog of all hospital services with associated charge codes and standard prices, used as the starting point for claim generation

The Chargemaster is the hospital's comprehensive service catalog: every procedure, supply, medication, and service has a unique charge code and list price. The CDM is the foundation of claim generation — charges trigger from the CDM when services are performed.

Question 14: What is 'upcoding,' and why does it constitute healthcare fraud?

Reporting a higher-level service than was actually performed to receive higher reimbursement — violates False Claims Act and anti-fraud laws (Correct answer)
Updating billing codes to the most current ICD/CPT versions
Using higher-level CPT codes for complex procedures that warrant them
Updating a code after receiving additional clinical documentation

Correct answer: Reporting a higher-level service than was actually performed to receive higher reimbursement — violates False Claims Act and anti-fraud laws

Upcoding intentionally assigns a more expensive code than the documented service supports to increase reimbursement. It violates the False Claims Act, exposing organizations to qui tam lawsuits, federal investigations, exclusion from Medicare/Medicaid, and civil monetary penalties.

Question 15: What is the 'Explanation of Benefits' (EOB) that patients receive?

A statement from the insurer explaining what was billed, what was paid to the provider, and what the patient owes (copay, deductible, coinsurance) — not a bill (Correct answer)
The itemized hospital bill for services rendered
A summary of the patient's insurance benefits for the policy year
The pre-authorization decision letter from the insurer

Correct answer: A statement from the insurer explaining what was billed, what was paid to the provider, and what the patient owes (copay, deductible, coinsurance) — not a bill

An EOB is an insurer's notification to the patient after a claim is processed. It shows: services billed, amount allowed, insurer payment, contractual adjustment, and patient responsibility. It says 'This is NOT a bill' — the provider bills the patient separately for the patient responsibility amount.

Question 16: What is 'timely filing' in medical billing, and what happens when it is missed?

The payer's deadline for submitting initial claims (e.g., Medicare 12 months, commercial often 90-180 days); claims submitted after the deadline are denied and typically cannot be appealed (Correct answer)
The hospital's internal deadline for coding completed encounters
The state regulation requiring billing within a specific number of days
The deadline for patients to pay their balances before collections

Correct answer: The payer's deadline for submitting initial claims (e.g., Medicare 12 months, commercial often 90-180 days); claims submitted after the deadline are denied and typically cannot be appealed

Each payer has a timely filing limit from the date of service. Medicare requires initial claims within 12 months; commercial payers often 90-180 days (varying by contract). Late filing denials are generally not appealable — the revenue is permanently lost.

Question 17: What is 'value-based reimbursement,' and how does it differ from fee-for-service?

Reimbursement based on quality outcomes and cost efficiency rather than volume of services; providers are rewarded for keeping patients healthy, not just for performing more procedures (Correct answer)
A payment model based on the value of individual procedures to the patient
Paying physicians based on their educational credentials and experience
A pricing model where patients pay based on perceived value of care

Correct answer: Reimbursement based on quality outcomes and cost efficiency rather than volume of services; providers are rewarded for keeping patients healthy, not just for performing more procedures

Fee-for-service pays per unit of service regardless of outcome. Value-based care (ACOs, shared savings, bundled payments, capitation) ties payment to quality metrics, cost efficiency, and patient outcomes. It incentivizes preventive care, care coordination, and avoiding unnecessary procedures.

Question 18: What is a 'payer contract,' and how does it affect hospital revenue?

A negotiated agreement between the hospital and insurer that defines contracted payment rates, covered services, billing requirements, and dispute resolution — directly determines reimbursement for insured patients (Correct answer)
An agreement between patients and their employer for insurance coverage
The hospital's agreement with medical supply vendors on payment terms
A contract governing participation in government healthcare programs

Correct answer: A negotiated agreement between the hospital and insurer that defines contracted payment rates, covered services, billing requirements, and dispute resolution — directly determines reimbursement for insured patients

Payer contracts establish the negotiated rates for each service. The contracted rate (often a percentage of charges or a fee schedule) is what the payer will pay. The difference between billed charges and contracted rate is the contractual adjustment — not revenue. Contract terms directly determine net revenue.

Question 19: What is 'self-pay' management in the revenue cycle?

The process of collecting balances from uninsured patients or patient responsibility (copays, deductibles) after insurance — including charity care screening, payment plans, and collection activities (Correct answer)
Managing revenue from patients who pay entirely in cash at time of service
The process of converting self-pay accounts to insurance claims
Billing patients directly instead of through insurance for administrative simplicity

Correct answer: The process of collecting balances from uninsured patients or patient responsibility (copays, deductibles) after insurance — including charity care screening, payment plans, and collection activities

Self-pay management addresses both uninsured patients (full balance) and insured patients' out-of-pocket responsibility. It includes: upfront collection at point of service, screening for charity care eligibility, setting up payment plans, and managing collections.

Question 20: What does 'modifier' mean in CPT coding, and give an example?

A 2-digit code appended to a CPT code to provide additional information about the service without changing the code definition (e.g., -25: significant, separately identifiable E&M on same day as procedure) (Correct answer)
A code that completely changes the meaning of the CPT code
A code that increases the reimbursement rate for a service
A code indicating the type of anesthesia used during a procedure

Correct answer: A 2-digit code appended to a CPT code to provide additional information about the service without changing the code definition (e.g., -25: significant, separately identifiable E&M on same day as procedure)

CPT modifiers provide additional information: -25 (separate E&M same day as procedure), -51 (multiple procedures), -59 (distinct procedural service), -26 (professional component), -TC (technical component), -LT/-RT (left/right side). They affect billing but not the core procedure definition.

Question 21: What is the 'False Claims Act' (FCA), and why is it critical to healthcare billing compliance?

A federal law prohibiting knowingly submitting false or fraudulent claims to federal programs (Medicare, Medicaid); violators face treble damages plus $11,000-$22,000 per false claim and exclusion from federal programs (Correct answer)
A state law governing billing disputes between patients and hospitals
A law requiring hospitals to inform patients when a claim is denied
A regulation requiring insurance companies to disclose claim denial reasons

Correct answer: A federal law prohibiting knowingly submitting false or fraudulent claims to federal programs (Medicare, Medicaid); violators face treble damages plus $11,000-$22,000 per false claim and exclusion from federal programs

The FCA (31 U.S.C. § 3729-3733) is the primary anti-fraud tool in healthcare. It allows the government (and whistleblowers via qui tam suits) to recover treble damages for fraudulent Medicare/Medicaid claims. Healthcare organizations face enormous FCA exposure from coding errors, unbundling, upcoding, and kickback violations.

Question 22: What is the role of the 'revenue integrity' department in a health system?

To monitor and ensure that charging, coding, and billing practices are accurate, compliant, and optimized to capture all legitimate revenue while avoiding compliance risks (Correct answer)
To audit financial statements for external reporting
To manage patient financial assistance programs
To negotiate payer contracts on behalf of the organization

Correct answer: To monitor and ensure that charging, coding, and billing practices are accurate, compliant, and optimized to capture all legitimate revenue while avoiding compliance risks

Revenue integrity teams work at the intersection of clinical documentation, coding, and billing. They perform charge audits, monitor CDM accuracy, identify missed charge opportunities, review high-risk billing areas, and ensure documentation supports the coded and billed services.

Question 23: What is 'bad debt' vs. 'charity care' in healthcare finance?

Bad debt is revenue expected but uncollectable from patients who can pay but don't; charity care is services provided to patients who are unable to pay, written off per formal financial assistance policy (Correct answer)
Bad debt is uncollectable insurance denials; charity care is uncollectable patient balances
They are interchangeable terms for uncompensated care
Bad debt is written off immediately; charity care is pursued by collections

Correct answer: Bad debt is revenue expected but uncollectable from patients who can pay but don't; charity care is services provided to patients who are unable to pay, written off per formal financial assistance policy

Charity care is provided to patients who qualify under the organization's financial assistance policy — it is never expected to be collected. Bad debt is the balance remaining from patients who were billed but did not pay and did not qualify for charity care — expected revenue that became uncollectable.

Question 24: What does 'coding query' (clinical documentation improvement query) accomplish in the revenue cycle?

CDI specialists ask physicians to clarify, add specificity, or confirm diagnoses in documentation to ensure accurate code assignment, optimizing DRG/quality reporting accuracy (Correct answer)
The billing department queries the coding team to expedite claim submission
Coders query the payer to clarify denial reasons
An automated query to the EHR for specific documentation elements needed for coding

Correct answer: CDI specialists ask physicians to clarify, add specificity, or confirm diagnoses in documentation to ensure accurate code assignment, optimizing DRG/quality reporting accuracy

A coding/CDI query is a compliant communication to the clinician asking for clarification (not suggesting a specific answer): 'Can you clarify if the patient's respiratory failure was hypoxic or hypercapnic?' This ensures documentation supports the most accurate, clinically specific codes.

Question 25: What is a 'remit code' (adjustment reason code) on an insurance remittance advice?

Standardized codes (CARC/RARC) explaining why a claim was paid differently from billed charges — required to understand payment calculation and identify denial reasons for follow-up (Correct answer)
Codes remitting the claim to a secondary insurer automatically
Provider codes identifying the rendering provider for payment routing
Patient codes identifying why the patient is responsible for the balance

Correct answer: Standardized codes (CARC/RARC) explaining why a claim was paid differently from billed charges — required to understand payment calculation and identify denial reasons for follow-up

Claim Adjustment Reason Codes (CARC) and Remittance Advice Remark Codes (RARC) explain payment adjustments: contractual (CO), patient responsibility (PR), other (OA), and payer-specific reasons. Revenue cycle staff use these codes to post payments accurately and identify denial types.
