CMS developed the National Correct Coding Initiative (NCCI) to promote national correct coding methodologies and to control improper coding leading to inappropriate payment in Part B claims. CMS developed its coding policies based on coding conventions defined in the American Medical Association's (AMA) CPT manual, national and local policies and edits, coding guidelines developed by national societies, analysis of standard medical and surgical practices, and a review of current coding practices. CMS annually updates the National Correct Coding Initiative Coding Policy Manual for Medicare Services and may make updates to individual edits quarterly. The Coding Policy Manual should be utilized by carriers and providers as a general reference tool that explains the rationale for NCCI edits.

Any claim processed by Iowa Medicaid where a correct coding edit posts has supplemental edit details available on this portal:
