National Correct Coding Initiative

Acronym: NCCI

The Centers for Medicare & Medicaid Services (CMS) developed the National Correct Coding Initiative (NCCI) to promote uniform, accurate coding methodologies and to combat improper and abusive coding. The policies are based on conventions defined by the American Medical Association, national societies and analysis of standard practices. The [National Correct Coding Initiative (NCCI) Coding Policy Manual](https://www.cms.gov/Medicare/Coding/NationalCorrectCodInitEd/index.html?redirect=/NationalCorrectCodInitEd/) is updated annually, with individual edits quarterly. The NCCI Coding Policy Manual should be utilized as a general reference tool that explains the rationale for NCCI edits. In cases where claims processed by Iowa Medicaid Enterprise (IME) shows a "correct coding edit" post on a provider's remittance advice statement, supplemental edit details are available on the [Correct Coding Edit Verification Portlet](https://secureapp.dhs.state.ia.us/impa/%28S%28pgtbrnt3vkhxwou3kvtzub22%29%29/review/bloodhound.aspx) by entering the Transaction Control Number (TCN) and billing NPI of the claim.
