Denial code · Last verified 2026-08-29
On a dental remittance, code PR 204 means: The service, equipment, or drug is not covered under the patient's current benefit plan. structural: appeal rarely changes it. Plan design is not appealable. Verify the right plan was adjudicated (employer plan changes mid-year cause false 204s), then move to the patient-pay conversation. Prevention is verification: benefit category checks before high-cost treatment plans.
Verdict
The denial reflects the plan's contract (an exclusion or an exhausted limit). Verify the payer applied the right facts, then move to the patient conversation rather than an appeal.

The plan-design cousin of code 96: the service category simply is not in this patient's contract — adult orthodontics on a plan without it, implants on an implant-excluded plan, cosmetic whitening anywhere.
