Bill Review
Enter the procedure codes from your medical bill or Explanation of Benefits (EOB). We'll check for codes that shouldn't have been billed together based on CMS bundling rules.
For educational use only. Results are based on CMS Medicaid National Correct Coding Initiative (NCCI) Procedure-to-Procedure edits. These rules apply to Medicare and Medicaid claims and may differ for private insurers. Modifier exceptions exist — a flagged pair does not necessarily mean your bill is wrong. Consult a medical billing advocate or your insurer for a definitive review.

What are NCCI PTP edits?The National Correct Coding Initiative (NCCI) is a CMS program that defines pairs of procedure codes that cannot (or can only under specific circumstances) be billed together. Column 1 codes are the “comprehensive” procedure; Column 2 codes are considered part of it and generally should not be billed separately. This tool uses the publicly available Medicaid NCCI edit files.
