Compliance and Payer Requirements

This domain tests whether claims are supported by documentation, medical necessity, and payer rules. Expect questions on National Correct Coding Initiative edits, local and national coverage determinations, advance beneficiary notices, and program integrity.

Payer rules and edits

  • NCCI procedure-to-procedure edits pair a column 1 and column 2 code. A modifier indicator of 0 means no modifier may override the edit; 1 means a proper modifier may.
  • Medically unlikely edits set maximum units for a code. Exceeding them requires documentation and may still deny.
  • Local coverage determinations and national coverage determinations define medical necessity; documentation must support the diagnosis, service, and frequency.
  • An advance beneficiary notice for Medicare must be voluntary, specific to the service, and signed before the service. Use modifier GA when signed and GZ when not signed.
  • Claim edits check NPI, place of service, units, and diagnosis linkage. Timely filing and appeal deadlines are payer-specific.

Documentation and program integrity

  • The medical record must support the code, site, time, and medical necessity. Cloning, upcoding, and unbundling create liability.
  • The seven elements of a compliance program are written policies, a compliance officer, training, communication, auditing, discipline, and corrective action.
  • The False Claims Act reaches knowingly false claims; HIPAA protects protected health information.
  • Prior authorization and eligibility verification are payer-specific and must be completed before nonemergency services when required.

Worked example

A Medicare beneficiary requests a service that does not meet the applicable LCD. The provider gives a compliant ABN before the service, explaining the likely denial and the patient's financial responsibility. The patient signs, and the claim is submitted with modifier GA. If the ABN is generic or signed after the service, it is invalid; the provider cannot bill the patient and may have to write off the balance.

Traps

  • Using blanket ABNs signed at check-in.
  • Using modifier 59 to override an NCCI edit without distinct documentation.
  • Reporting services before documenting medical necessity.
  • Missing the diagnosis-to-procedure link on the claim.
  • Assuming every payer follows Medicare rules.
