Denial Code CARC 234: This procedure is not paid separately

CARC 234 means: this procedure is not paid separately. Here's what it means in plain English, why it happens, and how it's worked toward payment.

Why you get a CARC 234 denial

• The code is a component bundled into a primary procedure under coding rules.
• A distinct service wasn't identified with a modifier.
• The edit is mutually exclusive and not separately payable.

How to fix or appeal CARC 234

1. Identify the bundling edit and whether a distinct service applies.
2. If documentation supports distinctness, resubmit with the correct modifier.
3. If it's a true mutually-exclusive edit, the component isn't separately payable — verify the primary paid at contract.

Sometimes recoverable with a supported modifier; often a legitimate bundle that isn't separately payable.

CARC 234 — FAQ

What does CARC 234 mean?

The procedure isn't paid on its own — it's considered part of another service. With documentation of a distinct service, a modifier may apply; otherwise it's a valid bundle.

Can I unbundle a CARC 234 denial?

Only when the record genuinely supports a separate, distinct service. The modifier must reflect the documentation, never be used solely to force separate payment.
