CODEMAP

Translate and validate medical codes across ICD-10, SNOMED CT, LOINC, RxNorm, and CPT from the CLI.

Healthcare & Life-Sciences — HIPAA, PHI, FHIR/HL7, and clinical data.

pip install cognis-codemap
codemap scan .            # → prioritized findings in seconds

Usage — step by step

1. Install:

   pip install -e .

2. Validate a code (the coding system is auto-detected) with the validate subcommand:

   codemap validate E11.9

   Validate a batch from a file (one code per line) for CI-friendly output:

   codemap validate --input codes.txt --format json

3. Crosswalk a code to equivalent concepts in other terminologies (ICD-10 / LOINC / RxNorm / CPT). Use --to to limit the target system and --table to supply your own terminology CSV:

   codemap crosswalk E11.9 --to RXNORM --format json

4. Read the result. validate reports per-code format (valid/INVALID) and whether it is known, exiting 1 if any code is invalid/unknown. crosswalk lists mapped concepts and exits 1 when there are zero matches. detect identifies the coding system of raw codes:

   codemap detect 4548-4

5. Use it in CI — fail when a code set contains anything invalid:

   codemap validate --input codes.txt --format json || {
     echo "Invalid/unknown medical codes present"; exit 1; }

Why codemap?

Offline, scriptable terminology crosswalk — turns a painful UMLS-portal lookup into a piped one-liner every clinical data engineer will star.

codemap is single-purpose, scriptable, and self-hostable: point it at a target, get prioritized results in the format your workflow already speaks (table · JSON · SARIF), gate CI on it, and let agents drive it over MCP.

Quick start

pip install cognis-codemap
codemap --version
codemap scan .                       # scan current project
codemap scan . --format json         # machine-readable
codemap scan . --fail-on high        # CI gate (non-zero exit)

Example

$ codemap scan .
  [HIGH    ] COD-001  example finding             (./src/app.py)
  [MEDIUM  ] COD-002  another signal              (./config.yaml)

Use it from any AI stack

codemap is interoperable with every popular way of using AI:

• MCP server — codemap mcp (Claude Desktop, Cursor, Cognis.Studio, uncensored-fleet)
• OpenAI-compatible / JSON — pipe codemap scan . --format json into any agent or LLM
• LangChain · CrewAI · AutoGen · LlamaIndex — wrap the CLI/JSON as a tool in one line
• CI / scripts — exit codes + SARIF for non-AI pipelines

How it compares

	Cognis codemap	OHDSI Athena + UMLS
Self-hostable, no account	✅	varies
Single command, zero config	✅	⚠️
JSON + SARIF for CI	✅	varies
MCP-native (AI agents)	✅	❌
Polyglot ports (JS/Go/Rust)	✅	❌
Open license	✅ COCL	varies

Built in the spirit of OHDSI Athena + UMLS, re-framed the Cognis way. Missing a credit? Open a PR.

Integrations

Pipes into your stack: SARIF for code-scanning, JSON for anything, an MCP server (codemap mcp) for AI agents, and a webhook forwarder for SIEM/Slack/Jira. See docs/INTEGRATIONS.md.
