The Centers for Medicare and Medicaid Services (CMS) developed the National Correct Coding Initiative (NCCI) to promote national correct coding methodologies and to eliminate improper coding. The Affordable Care Act of 2010 required state Medicaid programs to incorporate compatible NCCI methodologies in their systems for processing Medicaid claims.
NCCI associated modifiers may be appended when and only when appropriate clinical circumstances are documented in accordance with the NCCI policies and the HCPCS/CPT Manual instructions/definitions for the modifier/procedure code combination.
