Denial Code Decoder
PR-204 — Service not covered by the plan
The service is not a benefit of the patient's plan at all — an exclusion, not an eligibility or documentation problem. Because the plan simply does not buy this service, the balance usually moves to the patient IF they were positioned to know that in advance.
Billable to the patient? Usually yes, as a non-covered service — strongest when the patient was informed before the service; check your payer contract's notice requirements.

- Yes →
Was the patient informed the service might not be covered?
- Yes →
Bill the patient as non-covered. Move the balance to the patient with a statement explaining the plan exclusion — reference the notice they signed where applicable.
- No →
Review before billing. Billing a surprised patient for an excluded service is a compliance and relations risk — review your contract's notice requirements and your financial policy first, then add the service to the pre-service benefits checklist.
- Yes →
- No →
Appeal with the benefit evidence. Attach the eligibility/benefit response or plan document showing coverage and ask for reprocessing.
Prevention
Verify BENEFITS, not just eligibility, for services commonly excluded — the eligibility response's benefit detail, or a call, answers 'is this actually a covered benefit?' before the patient is on the table.
