Why PR-204 Happens, Common Root Causes

Service, equipment, or drug is not covered under the patient's current benefit plan. PR (Patient Responsibility) means the practice can bill the patient if proper notice was given. • Service is statutorily excluded from the plan (cosmetic surgery, vision exam without medical necessity, etc.) • Plan is a tiered network and the provider is in a non-covered tier • Plan benefit year reset and the service exceeded the new annual cap • Out-of-network provider with no out-of-network benefit on the plan • Drug not on the plan formulary

How to handle a PR-204 balance

PR-204 is rarely appealed because the patient is responsible. However: • If the service should be covered (payer error in benefit setup), call the payer's provider services line and request a benefit review • If the patient was given an Advance Beneficiary Notice (ABN) before the service, you can bill them directly with no appeal needed • If no ABN was given for a Medicare service, you generally cannot bill the patient (use modifier GZ on the original claim to flag this)

Before sending: if this is a Medicare claim and a valid Advance Beneficiary Notice (ABN) was not signed before the service, consult Medicare guidelines. Certain non-covered services cannot be billed to the patient without proper advance notice. Practices should maintain ABN records and verify signature status before generating patient statements for PR-denied Medicare claims.

🛡 Preventing PR-204 Denials

Verify benefits in real time before every visit, focus on coverage of the SPECIFIC service (CPT/HCPCS), not just whether the plan is active. Have patients sign an ABN whenever there is any chance Medicare will deny as not covered. Maintain a list of statutorily excluded services and flag them at scheduling. For commercial out-of-network situations, give the patient a written cost estimate and consent before performing the service.
