Quick Explanation
Denial code CO-182 indicates that the billing, rendering, or referring provider does not meet the credentialing, licensing, or specialty requirements to bill for the specific service submitted. Payers issue this denial when a procedure falls outside the provider's registered scope of practice, taxonomy code, or enrollment status under the plan.
Common Causes for CO-182
Denials with code CO-182 typically happen for the following specific reasons:
- The rendering provider's specialty or registered taxonomy code does not match the payer's requirements for the billed procedure code.
- A mid-level practitioner, such as a Physician Assistant or Nurse Practitioner, billed for a service that must be billed under a supervising physician or requires specific billing modifiers.
- The provider's credentialing application or CAQH profile is incomplete, outdated, or does not active-enroll them for the specific line of business.
- The rendered service falls completely outside the state-defined scope of practice for the billing provider type.
How to Prevent CO-182 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Verify and maintain up-to-date provider credentialing, CAQH profiles, and NPI registries with accurate specialty and taxonomy codes.
- Implement billing system edits that restrict certain specialized CPT codes from being billed under unqualified provider taxonomies.
- Apply appropriate modifiers, such as modifier SA or GP, to indicate services rendered by mid-level providers or therapists under applicable supervision guidelines.
- Conduct regular audits of payer-specific provider enrollment directories to ensure all active practitioners are properly paneled for the services they perform.
