Many procedure codes should not be reported together because they are mutually exclusive of each other. Mutually exclusive procedures cannot reasonably be performed at the same anatomic site or same beneficiary encounter.

NCCI has codes in pairs: Column 1/Column 2 are comprised of code pairs. If a provider submits the two codes of an edit pair for payment for the same beneficiary on the same date of service, the Column 1 code is eligible for payment and the Column 2 code is denied.
However, if both codes are clinically appropriate and an appropriate NCCI-associated modifier is used, the codes in both columns are eligible for payment. Supporting documentation must be in the beneficiary’s medical record.
The Medicare National Correct Coding Initiative (NCCI) (also known as CCI) was implemented to promote national correct coding methodologies and to control improper coding leading to inappropriate payment.
NCCI code pair edits are automated prepayment edits that prevent improper payment when certain codes are submitted together for Part B-covered services.
It is important to understand, however, that the NCCI does not include all possible combinations of correct coding edits or types of unbundling that exist. Providers are obligated to code correctly even if edits do not exist to prevent use of an inappropriate code combination. Should providers determine that claims have been coded incorrectly, they are responsible to contact their Medicare Administrative Contractor (MAC) about potential payment adjustments.
