How do I resolve a PR-204 denial?

Verify the patient's benefit plan exclusions and limitations: Confirm the service/equipment/drug is explicitly excluded or not listed as a covered benefit in the patient's plan documents to validate the PR-204 assignment. Check for alternative coverage options or plan changes: Determine if the patient has secondary coverage or if a different benefit plan period may include this coverage, particularly around plan renewal dates. Transfer balance to patient account and provide explanation: Post the patient responsibility amount, generate a statement explaining the benefit exclusion, and offer payment arrangements if applicable.
