The CMS (Centers for Medicare and Medicaid Services) has developed the National Correct Coding Initiative (NCCI) with the objective of promoting National correct coding methodologies and also to control improper coding that leads to wrong payments in Part B claims.

What are the CMS policies developed from? They include,

  • Coding conventions from CPT manual,
  • National and local policies / edits
  • Coding guidelines developed by national societies
  • Analysis of standard medical and surgical practices
  • Review of current coding practices.

Every year the CMS updates the Coding Policy Manual for Medicare. It is used as a general reference by the Medicare Carriers and Fiscal Intermediaries (FIs). The CMS Online Manual System is used by CMS program components, partners, contractors, and State Survey Agencies to administer CMS programs. It offers day-to-day operating instructions, policies, and procedures based on statutes and regulations, guidelines, models, and directives. For specific NCCI edits, one may submit comments in writing to:

The NCCI Edits Manual may also be obtained by purchasing the manual, or sections of the manual, from the National Technical Information Service (NTIS) website, or by contacting NTIS at 1-800-363-2068 or 703-605-6060.
