NCMA Medical Office Administration and Billing 1 — Questions and Answers

Question 1: What does ICD-10-CM stand for, and what is its primary purpose in medical billing?

International Clinical Diagnostic Manual, 10th revision; used for procedure billing
International Classification of Diseases, 10th revision, Clinical Modification; used to classify and code diagnoses (Correct answer)
Integrated Coding and Diagnosis, version 10; used for hospital billing only
Insurance Claims Database, 10th edition; used by payers to process claims

Correct answer: International Classification of Diseases, 10th revision, Clinical Modification; used to classify and code diagnoses

ICD-10-CM is the International Classification of Diseases, 10th revision, Clinical Modification — the U.S. standard coding system used to classify diagnoses, symptoms, and conditions for insurance billing, statistical analysis, and clinical documentation.

ICD-10-CM replaced ICD-9-CM in the U.S. on October 1, 2015. It contains over 70,000 codes (vs. ~14,000 in ICD-9). Structure: alpha-numeric, 3–7 characters. First character is a letter; 2nd and 3rd are numbers; 4th through 7th are alphanumeric extensions providing greater specificity (laterality, episode of care, anatomical detail). ICD-10-CM is used by all HIPAA-covered entities for outpatient diagnosis coding. ICD-10-PCS (Procedure Coding System) is used by hospitals for inpatient procedures. Accurate ICD-10 coding is essential for reimbursement, quality reporting, and research. Medical assistants must understand basic coding principles for claims submission and documentation.

Question 2: What is the purpose of the superbill (encounter form) in a medical office?

A bill sent to the patient for outstanding balances
A comprehensive form listing services rendered, diagnoses, and charges used to generate insurance claims (Correct answer)
An authorization form required before procedures can be performed
A government-mandated form for reporting communicable diseases

Correct answer: A comprehensive form listing services rendered, diagnoses, and charges used to generate insurance claims

The superbill (also called an encounter form or charge ticket) is an itemized document generated at each patient visit listing CPT procedure codes, ICD-10 diagnosis codes, charges, and provider information — used as the source document for insurance claim submission.

The superbill/encounter form serves as the foundation for claims submission. Components: patient demographics, insurance information, date of service, provider name and NPI, CPT procedure codes with units and charges, ICD-10 diagnosis codes linked to procedures, referring provider information (if applicable), and provider signature. Medical assistants may enter charges, confirm coding accuracy, and prepare superbills. After the visit, the billing department uses the superbill to generate CMS-1500 claim forms (outpatient) or UB-04 forms (inpatient/hospital). Accurate superbill completion reduces claim denials and delays in reimbursement.

Question 3: Which of the following best defines the term 'co-insurance' in health insurance?

A flat fee paid by the patient at the time of service
The percentage of covered medical costs the patient pays after meeting the deductible (Correct answer)
The maximum amount a patient pays out-of-pocket per year
A secondary insurance plan that covers what the primary plan does not

Correct answer: The percentage of covered medical costs the patient pays after meeting the deductible

Co-insurance is the percentage of medical costs the patient is responsible for paying after the deductible has been met. For example, with an 80/20 plan, insurance pays 80% and the patient pays 20% (co-insurance).

Key insurance terminology distinctions: Premium — monthly payment to maintain insurance coverage; Deductible — amount patient pays before insurance begins covering costs; Co-payment (copay) — fixed dollar amount per visit (e.g., $20/visit); Co-insurance — percentage patient pays after deductible (e.g., 20% of costs); Out-of-pocket maximum — the most a patient pays in a year; after this is met, insurance covers 100%; Coverage limit — maximum insurance will pay. Example: Patient has $1,000 deductible, 20% co-insurance, $5,000 out-of-pocket max. For a $3,000 bill: patient pays $1,000 deductible + 20% of remaining $2,000 ($400) = $1,400 total. Understanding these helps medical assistants explain patient financial responsibility.

Question 4: What is a Prior Authorization (PA) and when is it required?

A patient's consent form signed before all procedures
Advance approval from the insurance company required before certain procedures, medications, or referrals can be covered (Correct answer)
A physician's license to perform specialized procedures
An authorization to access the patient's electronic medical record

Correct answer: Advance approval from the insurance company required before certain procedures, medications, or referrals can be covered

Prior authorization is a pre-approval from a patient's insurance company that must be obtained before specific services, procedures, specialist referrals, or medications will be covered. Without PA, the claim may be denied.

Prior authorization (PA) is required by insurers for services deemed high-cost, high-risk, or potentially medically unnecessary — e.g., MRI/CT scans, elective surgeries, specialty drugs, physical therapy, specialist referrals (in HMO plans), durable medical equipment. PA process: (1) Provider's office identifies PA requirement via payer's coverage guide or portal; (2) Submit request with clinical documentation (diagnosis, supporting records, rationale for medical necessity); (3) Payer reviews and approves/denies within 2–5 business days (urgent requests within 72 hours); (4) Document authorization number in patient record; (5) Check expiration date. Failure to obtain required PA results in claim denial. Medical assistants often coordinate PA requests.

Question 5: When scheduling patient appointments, which scheduling system gives each appointment a fixed time slot and tends to minimize waiting room time?

Wave scheduling
Open booking
Stream (fixed interval) scheduling (Correct answer)
Modified wave scheduling

Correct answer: Stream (fixed interval) scheduling

Stream scheduling (also called fixed interval or time-specified scheduling) assigns each patient a specific appointment time at regular intervals (e.g., every 15–30 minutes). When followed, it minimizes patient wait times.

Scheduling systems comparison: Stream/fixed interval — each patient has a specific time; works well when visits are predictable length; minimizes waiting if provider stays on schedule; Wave scheduling — multiple patients scheduled at the start of each hour (e.g., 3 patients at 9:00 AM); works on the assumption some will be late or quick; Modified wave — 2 patients at :00, 1 at :30; balances wave benefits with reduced crowding; Open access (advanced access/same-day) — most slots held for same-day scheduling; reduces no-show problem; Double-booking — two patients in the same slot; used for urgent add-ons. Most practices use modified wave or stream scheduling with provisions for urgent add-ons. Scheduling skill is a core medical assistant competency.

Question 6: A patient calls to schedule a procedure but their insurance has not yet responded to the prior authorization request. What is the most appropriate response?

Schedule the procedure anyway since the insurance will likely approve it
Inform the patient that the authorization is pending, provide an estimated timeframe, and schedule only after authorization is received or based on physician guidance (Correct answer)
Tell the patient to call their insurance company themselves to follow up
Cancel the prior authorization request and have the patient pay out of pocket

Correct answer: Inform the patient that the authorization is pending, provide an estimated timeframe, and schedule only after authorization is received or based on physician guidance

Scheduling a procedure before receiving prior authorization risks claim denial and unexpected patient financial liability. The appropriate response is to communicate transparently with the patient, continue following up with the payer, and schedule only after authorization is confirmed or per the physician's guidance for urgent cases.

Prior authorization management best practices: (1) Submit PA requests promptly with complete clinical documentation; (2) Follow up with payer if no response within 2–3 business days; (3) Document all PA communications in the patient record (request date, confirmation number, approval/denial, expiration); (4) Communicate status to the patient proactively; (5) For urgent/emergent procedures, the physician may need to proceed without PA and appeal retrospectively; (6) If PA is denied, initiate appeals process with clinical documentation. HIPAA and CMS regulations require payers to respond to standard PA requests within 72 hours and expedited/urgent requests within 24–72 hours. State laws vary. Patient education about potential out-of-pocket costs is essential.
