What Does OA-234 Mean?

With OA, the bundling edit was applied during coordination of benefits.

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.
