NCMA Medical Office Administration and Billing 2 — Questions and Answers

Question 1: What does the CMS-1500 claim form primarily contain, and who uses it?

A hospital billing form for inpatient services, used by hospitals
A standardized claim form for professional outpatient services submitted by physicians and non-institutional providers to payers (Correct answer)
A patient statement form showing balance due after insurance payment
A form used exclusively for Medicare Advantage claims

Correct answer: A standardized claim form for professional outpatient services submitted by physicians and non-institutional providers to payers

The CMS-1500 (also called the HCFA-1500) is the standard paper claim form used by physicians, medical practices, and non-institutional providers to submit professional outpatient service claims to Medicare, Medicaid, and most commercial payers.

CMS-1500 key information: Boxes 1–13 contain patient and insurance information; Boxes 14–33 contain physician and service information. Key fields: Box 21 — ICD-10 diagnosis codes (up to 12); Box 24 — service date, place of service, CPT codes, modifiers, diagnosis pointers, charges, days/units; Box 25 — provider Tax ID; Box 33 — billing provider NPI and address. The UB-04 (CMS-1450) is used by hospitals and institutional providers for inpatient and outpatient hospital services. Electronic claims are submitted via 837P (professional) and 837I (institutional) HIPAA standard transaction sets. Most practices submit electronically but must understand both paper and electronic formats.

Question 2: What is a Coordination of Benefits (COB) scenario in medical billing?

When two providers coordinate services to treat the same condition
When a patient has more than one insurance plan and rules determine which pays first (primary) and which pays second (secondary) (Correct answer)
When the physician coordinates the patient's referral to a specialist
When a billing error requires two departments to coordinate corrections

Correct answer: When a patient has more than one insurance plan and rules determine which pays first (primary) and which pays second (secondary)

Coordination of Benefits (COB) is the process that determines the order in which multiple insurance plans pay when a patient is covered by more than one plan. The primary payer pays first; the secondary payer covers remaining eligible costs.

COB rules and scenarios: Birthday Rule — for dependents covered under both parents' plans, the parent whose birthday falls earlier in the calendar year has the primary plan; Medicare secondary payer (MSP) rules govern employer group health plans with 20+ employees — employer plan is primary, Medicare is secondary; COB for active employee — own employer plan is primary; spouse's plan is secondary. COB process: submit full claim to primary payer, obtain EOB (Explanation of Benefits), submit remaining balance to secondary payer with primary EOB. The goal is to prevent overpayment (total payments should not exceed 100% of covered charges). Medical assistants must collect all insurance cards and verify COB at every visit.

Question 3: What is the difference between an HMO and a PPO insurance plan as it affects patient scheduling in a medical office?

HMOs cover preventive care; PPOs cover only sick visits
HMOs require referrals for specialist visits and restrict to in-network providers; PPOs allow direct specialist access with out-of-network coverage at higher cost (Correct answer)
HMOs are government plans; PPOs are private insurance plans
Both are identical in their referral and network requirements

Correct answer: HMOs require referrals for specialist visits and restrict to in-network providers; PPOs allow direct specialist access with out-of-network coverage at higher cost

HMOs (Health Maintenance Organizations) require patients to select a primary care physician (PCP) who coordinates care and provides referrals to specialists. PPOs (Preferred Provider Organizations) allow direct specialist access without referrals and offer out-of-network coverage.

Insurance plan types affecting scheduling: HMO — patient must have a designated PCP; specialist visits require PCP referral (gatekeeper model); must use in-network providers (except emergencies); typically lower premiums and copays; referral required before MA can schedule specialist; PPO — no PCP requirement; no referrals needed; can see any provider (higher cost out-of-network); higher premiums, lower restrictions; HDHP (High Deductible Health Plan) — high deductible, lower premiums, often paired with HSA; POS (Point of Service) — hybrid of HMO/PPO; EPO (Exclusive Provider Organization) — no referrals but must use network. Medical assistants must verify plan type to determine whether referrals are required before scheduling specialist visits.

Question 4: In medical billing, what does the term 'clean claim' mean?

A claim submitted by a provider with no unpaid prior balances
A claim that is complete, accurate, and contains all required information allowing the payer to process it without requesting additional information (Correct answer)
A claim that has been fully paid with no patient balance remaining
A claim that has been audited and found free of coding errors

Correct answer: A claim that is complete, accurate, and contains all required information allowing the payer to process it without requesting additional information

A clean claim is one that passes all payer edits and contains complete, accurate information (patient demographics, valid codes, provider NPI, authorization numbers, etc.) allowing the insurer to process and adjudicate it without returning it for additional information.

Clean claim requirements: Valid, current ICD-10 and CPT codes; Complete patient demographics (name, DOB, address, insurance ID); Provider information (NPI, Tax ID, address); Date of service; Proper diagnosis-to-procedure code linkage; Required modifiers; Authorization numbers (if required); Place of service code; Referring provider NPI (if applicable). Payers are legally required to process clean claims within specific timeframes: Medicare: 30 days (electronic), 45 days (paper); Medicaid: varies by state (typically 30 days); commercial: varies, often 30–45 days. Common reasons claims are not clean: invalid codes, missing information, duplicate claims, services not covered, or coordination of benefits issues.

Question 5: What is a National Provider Identifier (NPI), and who requires it?

A unique patient identification number required by all insurance companies
A standard 10-digit identifier issued by CMS to all healthcare providers covered under HIPAA for billing purposes (Correct answer)
A license number assigned by each state medical board to physicians
An identification number used only for Medicare billing

Correct answer: A standard 10-digit identifier issued by CMS to all healthcare providers covered under HIPAA for billing purposes

The NPI (National Provider Identifier) is a unique 10-digit identification number issued by the CMS National Plan and Provider Enumeration System (NPPES) to all HIPAA-covered healthcare providers. It is required on all standard healthcare transactions.

NPI facts: Issued by NPPES (National Plan and Provider Enumeration System); 10-digit number, no embedded intelligence (unlike older legacy IDs); Required on all HIPAA standard transactions including claims (CMS-1500, UB-04), eligibility verification, and referrals; Individual providers (physicians, NPs, PAs, MAs who bill) receive Type 1 NPI; Organizational providers (group practices, hospitals) receive Type 2 NPI; Does not expire and is not practice-specific (follows the provider). On CMS-1500: Box 33a = billing provider NPI; Box 24j = rendering provider NPI; Box 17b = referring provider NPI. Medical assistants may be asked to look up NPIs via the NPPES NPI registry (nppes.cms.hhs.gov) when processing referrals or verifying provider information.

Question 6: A patient hands you their insurance card at check-in, but the information in the EHR shows a different plan from their last visit. What should you do?

Use the EHR information since it was verified at the last visit
Copy both sides of the new card, update the EHR, verify eligibility and benefits with the payer, and confirm any changes affect the current visit (Correct answer)
Ask the patient to have their employer call the office to verify the change
Bill using the old plan and submit to the new plan only if the old plan denies

Correct answer: Copy both sides of the new card, update the EHR, verify eligibility and benefits with the payer, and confirm any changes affect the current visit

Insurance information must be verified at every visit. When a patient presents new insurance, update the EHR immediately, copy both sides of the card, and verify eligibility in real time through the payer portal or clearinghouse to confirm current coverage and benefits before the visit.

Insurance verification best practices at check-in: (1) Collect insurance card(s) at every visit — patients change insurance between visits; (2) Copy both sides of all insurance cards for records; (3) Update patient demographics and insurance in EHR; (4) Verify eligibility electronically via payer portal, clearinghouse (e.g., Change Healthcare, Availity), or phone; (5) Confirm: plan effective date, covered services, copay/deductible amounts, referral requirements, prior auth requirements; (6) If secondary insurance, determine COB order; (7) Collect copay at time of service; (8) Document eligibility verification results. Failure to verify current insurance is a leading cause of claim denials and patient billing complaints.
