The Centers for Medicare and Medicaid Services (CMS) expects state Medicaid programs to follow the rules of the National Correct Coding Initiative (NCCI). CMS created the NCCI in 1996. NCCI promotes correct coding practices nationwide and controls incorrect coding, which can lead to incorrect payments for Medicaid claims.

Coding policies are made based on rules found within the following tools:

  • American Medical Association's Current Procedural Terminology (CPT) manual
  • National and local policies
  • Recent changes to national and local policies
  • Coding guidelines from national societies
  • Analysis of standard medical and surgical practices
  • Reviews of current coding rules.

CMS reviews and updates these policies yearly to ensure all NCCI coding practices match Medicaid claims.

The CMS website contains the following:

  • Medicaid-specific NCCI manuals
  • More information about NCCI
  • NCCI Policies Coding Policy Manuals
  • NCCI (procedure to procedure and MUE) edits

Compliance checks take place to evaluate claims against the NCCI edits both before and after payment. Reviewing pre-payment editing may result in claim denial; reviewing post-payment editing may result in a refund request.

CMS instructs states to use NCCI edits first. Edits from each state are then applied to the claims. Payment of a claim is dependent on compliance with all NCCI and Nebraska-specific edits.

Most Nebraska Medicaid claims are compatible with CMS standards. Nebraska Medicaid will post changes and helpful tools as they become available.
