Denial Code PR-204
This service/equipment/drug is not covered under the patient's current benefit plan
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)
Recommended action: send patient statement
This balance is the patient's responsibility under their plan design. Send a patient statement. For Medicare non-covered services, ensure a valid Advance Beneficiary Notice (ABN) was signed before the service — without one, you generally cannot bill the patient.
Patient statement template
Use this statement to bill the patient for the adjusted amount. Before sending, verify the patient owes the balance per their plan (and for Medicare, that a valid ABN was signed when required).
[Your Practice Letterhead] [Date] [Patient Name] [Patient Address] Re: Account Balance, Date of Service [DOS] Claim Number: [Claim Number] Dear [Patient Name]: Your insurance claim for the service provided on [DOS] has been processed by [Payer Name]. The insurer has determined that the following amount is your responsibility under your plan benefit design: Adjustment code: PR-204 Description: This service/equipment/drug is not covered under the patient's current benefit plan Amount due: $[Amount] This amount represents your [deductible / copay / coinsurance / non-covered portion] per your plan terms. Please remit payment by [Due Date] or contact our billing office at [Phone] to arrange a payment plan. If you believe this amount is incorrect, please contact [Payer Name] member services using the number on the back of your insurance card to verify your benefit details. Sincerely, [Practice Name] Billing Department [Phone] · [Email] --- 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.
