2021 Evaluation & Management Changes

Significant changes were made to the office and outpatient Evaluation and Management services in 2021. Read more about the updates in 2021 Coding Updates and Changes: CPT®, HCPCS, and ICD-10 CM and on the Coding and Reimbursement page.


Coding Edits

The National Correct Coding Initiative (NCCI) edits are developed by CMS to establish a uniform coding review method among MACs (Medicare Administrative Contractors). NCCI edits help the agency promote correct coding, enforce Medicare payment policies, and control improper payments made by inappropriate coding. The Centers for Medicare and Medicaid Services publishes updates to the NCCI edits for Procedure to Procedure and Medically Unlikely Edits on a quarterly basis. The organization also publishes the NCCI policy manual on an annual basis.
