PR-234: Procedure Not Paid Separately
Patient charges for a bundled procedure are unusual. Review whether modifiers can resolve the denial.
What Does PR-234 Mean?
With PR, the patient is responsible for the bundled procedure. This is unusual for a coding edit.
CARC 234 indicates the billed procedure is bundled into another procedure and cannot be paid separately. The payer's edits (NCCI or proprietary) determined that the denied procedure is an inherent part of a more comprehensive procedure also billed on the claim. The payment for the comprehensive procedure already includes compensation for the component procedure.
This is a common bundling denial in surgical cases where multiple procedure codes are submitted but some are considered integral to the primary procedure. It also occurs with evaluation and management (E/M) codes that are bundled into global surgical packages.
How to Resolve
- Check for modifier overrides Determine if the denial can be resolved.
- Collect if unresolvable If the procedure is truly bundled, communicate charges.
Procedure Not Paid Separately reflects a bundling or NCCI edit — the service was paid as part of another procedure on the same claim. Bundling is governed by published coding edits, so a direct appeal usually doesn't apply. Verify the edit, and if a modifier (such as 59 or XS/XU) legitimately unbundles the services, submit a corrected claim instead.
How to Prevent PR-234
- Review coding before submission to prevent patient charges from bundling edits
