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

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

Answer: (D)

The key idea here is that some payer systems use rules that diverge from the standard coding and reimbursement framework, so an auditor must spot when those non-standard rules apply. Auto accident and Workers’ Compensation programs are classic cases of this. They operate under state-specific statutes, separate medical-fee schedules, and third-party liability or subrogation processes, along with unique billing practices such as medical-legal evaluations and impairment ratings. These factors mean codes, modifiers, and reimbursement calculations may not align with the usual CPT/HCPCS and payer guidelines used for most private or government plans. An auditor needs to identify when these non-standard rules govern a claim to ensure proper coding, compliance, and payment. Commercial insurance, Medicaid, and Medicare generally follow more uniform, widely established coding and reimbursement structures across claims, so while variations can occur, the need to uncover non-standard rules is not as pronounced as with auto and workers’ compensation.
