NCCI (National Correct Coding Initiative) edits are code pairs established by CMS (Centers for Medicare & Medicaid Services) that cannot be billed together by the same provider on the same date of service. These edits prevent improper payment for codes that represent components of a more comprehensive procedure already captured elsewhere in the claim. Accurate application of NCCI edits is essential for clean claims and compliance. Nym’s autonomous medical coding engine automatically applies current NCCI edits, which are updated quarterly by CMS, ensuring proper code pairing and reducing denials caused by bundling errors.
