Denial code 104 means: Your plan applied a managed care withholding, an amount held back from the provider's payment under the provider's managed care contract.

Why it happens: Patients see this as a contractual amount withheld from the provider under their managed care agreement, not a charge owed by the patient.

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 104 may appear on your remittance with a group-code prefix such as PR-104 (patient responsibility) or CO-104 (contractual obligation). The denial reason is the same.
