D15
PrimaryCO-185

In plain language

The specific individual listed as having performed the service is not, per the payer's records, allowed to perform/bill that type of service — this differs from D14 (overall enrollment) in that it focuses on scope-of-practice/specialty eligibility for this particular service.

Start here

Confirm who actually performed the service per the medical record.

Who resolves it

Billing, Credentialing

Who prevents it

Clinical Department — ensure supervision requirements are met and documented for incident-to/shared services; Credentialing — confirm specialty-specific payer eligibility before scheduling.

Work these steps in order for D15 / CO-185

How to resolve this denial, step by step

  1. 1

    Confirm who actually performed the service per the medical record.

  2. 2

    Verify that provider's NPI and specialty were correctly submitted.

  3. 3

    If a data-entry error, correct and resubmit.

  4. 4

    If the actual rendering provider is not eligible for that service under payer policy, evaluate whether the service can be legitimately billed under the supervising/collaborating provider per incident-to or shared-service rules (only if those rules were actually met — direct supervision, established patient/plan of care, etc.).

  5. 5

    Document the eligibility finding.

  6. 6

    Escalate to Credentialing/Clinical Department if the provider needs additional certification or if supervision requirements were not actually met.

Then choose the correct disposition

Corrected claim

only for a data-entry error where an eligible provider was mis- identified.

Provider enrollment correction

when the actual provider needs additional payer-specific credentialing.

Compliance escalation

if there is any suggestion of billing under a different provider's NPI when that provider did not actually perform or properly supervise the service.

Stop and escalate when

  • Supervision requirements for incident-to billing were not actually met (compliance issue, not a billing fix); provider scope-of-practice dispute with payer.

What Needs to Be Corrected

  • Claim correction: If the correct, eligible rendering provider was simply omitted or mis- entered, correct the NPI/name and resubmit.
  • Upstream correction: If the rendering provider genuinely is not eligible to bill that service type with that payer, this is a credentialing/scope-of-practice issue; the fix is enrollment or supervision-workflow correction, not claim substitution.

Do Not Do This

  • Do not change the rendering provider merely because the submitted provider is not enrolled or eligible, unless the true supervising/billing provider under incident-to or shared-service rules can legitimately be billed and all requirements (direct supervision, established patient, established plan of care) were actually met.
  • Do not misrepresent who performed the service.
