Among the examples below, which may require an auditor to identify non-standard coding and reimbursement rules?

• A. Medicare plans
• B. Medicaid plans
• C. Auto and Workers' Compensation
• D. Commercial insurance carriers

Answer: (A)

Understanding payer-specific coding and reimbursement rules is essential for accurate auditing. Medicare plans are known for a dense set of policies that often diverge from routine CPT/HCPCS billing, including National Correct Coding Initiative edits, coverage determinations, and distinct outpatient versus physician payment rules. Auditors must spot when a claim uses codes or modifiers that don’t align with Medicare’s rules or when payment methods depart from standard practice due to bundles or special rule sets. This is why Medicare plans frequently require identifying non-standard coding and reimbursement rules. Medicaid and Auto/Workers' Compensation involve their own state- or program-specific complexities, but the example that best illustrates the need to identify non-standard rules in many audits is Medicare, while commercial carriers tend to align more closely with standard coding guidelines.
