FAQ from NCCI Claims Validation — CPT Code Pair Edits + MUE Limits

How does this differ from using raw CMS NCCI files?

It provides instant, programmatic validation with clear modifier guidance instead of requiring manual parsing of quarterly CMS data.

What are the dependencies and runtime requirements?

Requires Node.js and npx. The server runs locally via stdio or can be deployed as an HTTP server.

Where does the NCCI data live, and is it updated?

Data is bundled with the server and covers multiple specialties. It can be updated by running npm run build-data. Each response includes the CMS quarter (dataVersion) and build date.

What transports and authentication are available?

Default transport is stdio; set PORT env var for Streamable HTTP mode on /mcp. HTTP servers optionally require an ADMIN_SECRET for the checkout and admin endpoints. The MCP tools themselves do not require authentication.

Are there any usage limits?

Yes. The free plan allows 20 validations per day with 5 per minute rate. Paid plans remove those limits (Starter: 500/day, Pro: 5,000/day, Business: 50,000/day).
