CO-184 — Ordering provider not eligible to order/prescribe
Claim-adjustment reason code 184 · typically reported as CO-184
What it means
The prescriber on the claim isn’t eligible to order this item per the payer’s enrollment records — the DME version of the PECOS denial.
Why DME claims hit it
- Ordering physician not PECOS-enrolled or opted out of Medicare
- Practitioner type not permitted to order the item under program rules
How to fix it
- Check the ordering provider against the Medicare ordering/referring file BEFORE delivery — build it into intake
- Get the order re-issued by an enrolled practitioner when needed
Appeal posture
Generally no — the enrollment fact controls. Fix intake screening so it never recurs.
