Denial code 223 means: This is an adjustment for a mandated federal, state, or local law or regulation that is not already covered by another code.

Why it happens: You typically see this when a specific law or regulation requires an adjustment to the claim and no existing reason code applies to that mandate.

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 223 may appear on your remittance with a group-code prefix such as PR-223 (patient responsibility) or CO-223 (contractual obligation). The denial reason is the same.
