What is the purpose of the National Correct Coding Initiative (NCCI) edits?

• A. To increase reimbursement rates for high-cost services.
• B. To create hospital coding manuals.
• C. To train physicians on coding.
• D. To standardize coding and prevent improper coding by restricting the use of certain CPT/HCPCS code combinations.

Answer: (D)

The main idea behind NCCI edits is to promote consistent, accurate coding by preventing improper combinations of codes. These edits identify CPT/HCPCS code pairings that shouldn’t be billed together because the work of one code is already encompassed in another, or because combining them would inflate payment. By flagging these pairings, they steer claims processing toward the correct reimbursement—often paying for only the appropriate bundled service or for the lower-valued code, unless an exception is justified with the right modifier. This standardized approach helps reduce overpayments and coding errors across payers, including Medicare.
