The National Correct Coding Initiative in Medicaid
On February 1, 2019, the National Correct Coding Initiative (NCCI) Medicare and Medicaid program contract was awarded to a new contractor, Capitol Bridge LLC. For more information, see the NCCI Program New NCCI Contractor Announcement 02/08/2019.
The Center for Medicare & Medicaid Services (CMS) National Correct Coding Initiative (NCCI) promotes national correct coding methodologies and reduces improper coding which may result in inappropriate payments of Medicare Part B claims and Medicaid claims. Visit National Correct Coding Initiative Edits for information about, and edits for, the Medicare NCCI program. The Medicaid NCCI program has significant differences from the Medicare NCCI program.
The Affordable Care Act of 2010 required CMS to notify states by September 1, 2010, of the NCCI methodologies that were compatible with Medicaid. State Medicaid Director Letter notified states that all five Medicare NCCI methodologies were compatible with Medicaid. The Affordable Care Act required state Medicaid programs to incorporate compatible NCCI methodologies in their systems for processing Medicaid claims by October 1, 2010.
Types of NCCI Edits
The NCCI contains two types of edits:
- NCCI procedure-to-procedure (PTP) edits that define pairs of Healthcare Common Procedure Coding System (HCPCS)/Current Procedural Terminology (CPT) codes that should not be reported together for a variety of reasons. The purpose of the PTP edits is to prevent improper payments when incorrect code combinations are reported.
- Medically Unlikely Edits (MUEs) define for each HCPCS/CPT code the maximum units of service (UOS) that a provider would report under most circumstances for a single beneficiary on a single date of service.
