ncci-check is a command for Claude Code from rdmgator12/RE-MCP-. It costs 0 tokens per session (271 once invoked), scanned A, original, MIT.

A command for checking National Correct Coding Initiative procedure-to-procedure edits between Medicare billing codes. These edits indicate when one medical procedure code may be bundled into another.

In plain words
What is it for?
Use it to check two or more CPT or HCPCS codes, review modifier guidance and edit reasons, analyze bundles, and estimate total Medicare payment when multiple codes are supplied.
Why use it?
It helps identify code pairs that Medicare may not pay separately and clarifies whether a billing modifier can change that result.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ncci-check scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

/ncci-check

Check NCCI PTP edits between two or more CPT/HCPCS codes.

Usage

/ncci-check <code1> <code2> [--hospital] [--disclosure]
/ncci-check <code1> <code2> <code3> ... [--hospital]

Examples

/ncci-check 29881 29877

What It Does

Two codes:

  1. Checks both directional NCCI PTP edits
  2. Returns modifier indicator (can unbundle or cannot)
  3. Recommends specific modifier if applicable
  4. Shows edit rationale and effective date

Three or more codes:

  1. Runs full bundle_analyzer on all codes
  2. Checks all pairwise NCCI edits
  3. Determines which codes are payable vs bundled
  4. Calculates expected total Medicare payment
  5. Provides recommended billing with modifiers

Tools Used

  • check_ncci_edits — For two-code checks
  • bundle_analyzer — For three or more codes
  • modifier_advisor — For modifier recommendations

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
