NHA CBCS — Medical Billing & Coding

Questions cover the four official NHA domains: the revenue cycle and regulatory compliance (HIPAA, fraud vs abuse), insurance eligibility and payer requirements (coordination of benefits, cost-sharing, prior authorization), coding and coding guidelines (ICD-10-CM Official Guidelines, CPT and HCPCS Level II concepts, modifiers, NCCI), and billing and reimbursement (CMS-1500, rejection vs denial, appeals). Grounded in public standards (HHS HIPAA, CMS, NUCC, ICD-10-CM Official Guidelines) — no copyrighted CPT descriptors are reproduced. The real exam is English-only; the multilingual explanations are a study aid.
