OA-184: Prescribing/Ordering Provider Not Eligible to Prescribe/Order

What Does OA-184 Mean?

With OA (Other Adjustments), the ordering provider eligibility issue was flagged during coordination of benefits. The provider's status must be resolved before any payer can process the claim.

CARC 184 indicates that the prescribing or ordering provider listed on the claim does not meet the payer's requirements for writing prescriptions or orders. This could mean the ordering provider is not enrolled with the payer, their NPI is invalid, their license type does not authorize prescriptive authority for the specific service or medication, their DEA number is expired, or they have been excluded from federal healthcare programs.

This code commonly affects claims for DME, home health services, laboratory tests, and prescription medications where a valid order from an eligible provider is mandatory. The payer validates the ordering provider's credentials during claim processing and rejects claims when the provider does not meet prescriptive authority requirements.

How to Resolve

1. Identify which payer flagged the issue Review the remittance to determine which payer identified the ineligible ordering provider.
2. Resolve the provider's eligibility Correct the NPI, obtain a new order, or appeal with documentation.
3. Resubmit through the COB sequence Submit the corrected claim through the proper payer priority order.
