Denial code 256 means: The service is not payable under the terms of the managed care contract between the provider and the plan.

Why it happens: You typically see this when the billed service falls outside what the provider's contract with your managed care plan allows, which is usually a provider and payer contract matter rather than a patient charge.

Is it appealable? This code reflects a patient-cost or contractual amount, not a denial you appeal directly. If you believe it was applied in error, the underlying claim can be reviewed.

What to send: the missing element for this code, a short appeal letter citing the plan's claims-procedure rules, and any clinical support.

Note: code 256 may appear on your remittance with a group-code prefix such as PR-256 (patient responsibility) or CO-256 (contractual obligation). The denial reason is the same.
