PR-204 Denial Code: Service Not Covered by Benefit Plan
The PR-204 denial code means the service, equipment, or drug is not covered under the patient's current benefit plan, so the Patient Responsibility group routes the cost to the patient. For out-of-network behavioral-health practices this is the everyday result, and the patient recovers what they can through out-of-network benefits with a superbill. Always check first for a covered alternative before accepting PR-204 as final.
What is the PR-204 denial code? PR-204 is a Claim Adjustment Reason Code (CARC) indicating the service, equipment, or drug is not covered under the patient's current benefit plan, carried under the Patient Responsibility group so the amount is billable to the patient.
Undeny's Take
PR-204 is where transparency pays for itself. The denial is often correct — the plan simply doesn't cover this service or this provider — so the win isn't appealing, it's setting expectations before the visit. For out-of-network behavioral-health practices, PR-204 is the normal result, and the patient recovers what they can through their out-of-network benefits using a superbill. Before you accept a PR-204, check the cheap upside: a different but clinically appropriate covered code, a corrected place of service, or in-network telehealth coverage can sometimes turn a non-covered claim into a paid one.
PR-204 and the Benefit Plan
PR-204 corresponds to X12 code 204: "This service/equipment/drug is not covered under the patient's current benefit plan." The PR group code assigns the amount to the patient, signaling the plan does not include this benefit. It differs from medical-necessity or authorization denials — the plan simply has no benefit for this service, so payment responsibility falls to the patient under the contract.
Why a Plan Excludes a Service
- The service is excluded from the patient's specific plan.
- The provider is out of network and the plan has no out-of-network benefit for the service.
- The plan covers a different setting, code, or modality than the one billed.
- A non-covered add-on or ancillary item was billed alongside a covered service.
Out-of-Network Options and Appeals
- Confirm the service is genuinely non-covered for this plan — check for a covered alternative code, setting, or telehealth benefit.
- If a correctable error caused the non-coverage, submit a corrected claim before billing the patient.
- If non-coverage is correct, bill the patient and provide a superbill so they can pursue any out-of-network reimbursement.
- If you believe the service should be covered, appeal with the benefit and policy citation, or draft it with the appeal generator.
PR-204 Versus Other Non-Coverage Codes
PR-204 is one of several non-coverage codes; the group code decides who pays. PR-96 is non-covered charges, also patient responsibility, that requires a remark code. CO-96 is non-covered as a contractual write-off you cannot bill the patient. Browse the full set under denial codes.
Frequently Asked Questions
What does PR-204 mean?
PR-204 means the service, equipment, or drug is not covered under the patient's current benefit plan. The PR group makes the amount patient responsibility, so the cost shifts to the patient rather than being written off.
Can I bill the patient for a PR-204 denial?
Usually yes, because the PR group assigns responsibility to the patient — but only when non-coverage is genuine and your contract and advance-notice practices support it. Rule out a correctable error before invoicing the patient.
What is the difference between PR-204 and CO-96?
PR-204 means not covered under the benefit plan and the patient owes; CO-96 means non-covered as a contractual write-off the provider absorbs. The group code (PR vs CO) determines who is responsible for the amount.
How do out-of-network therapists handle PR-204?
For out-of-network practices, PR-204 is the expected response. Collect from the patient and provide a superbill so they can submit it to their plan for any out-of-network reimbursement. Verifying out-of-network benefits up front sets clear expectations.
