Do these two codes bundle?
Paste a CPT pair. Get the NCCI Procedure-to-Procedure verdict, the modifier indicator, and the modifier path that may bypass the edit when clinically supported.
Unknown code:
Verify the CPT format. Both codes must be valid Current Procedural Terminology codes (5 digits, or 4 digits + a letter for Category II/III).
What the modifier indicator means
The two codes cannot be unbundled under any circumstance. No modifier bypass is allowed. Bill only the column 1 code; write off the column 2 charge or do not submit it.
A modifier (typically 59 or an X-modifier: XE, XS, XP, XU) can bypass the edit when documentation supports a distinct, separately identifiable service. Documentation is the deciding factor.
No modifier indicator is applicable to this code pair. The pair may not require a modifier decision, or the edit was retired by CMS. Always verify against the current NCCI quarterly file.
