SNOMED Codes

Search and lookup SNOMED CT clinical concepts via the @sequoiaport/codes package.

When to Apply

• User asks for a SNOMED concept or concept ID
• User needs standardized clinical terminology
• User wants to map a clinical condition to SNOMED CT
• User mentions clinical ontology or concept hierarchies

Getting an API Key

First check if SEQUOIA_CODES_API_KEY is already set in the environment. If it is, skip key generation entirely and proceed to usage. Only if no key exists, see AGENT_PROMPT.md for how your agent can obtain one via the agent auth flow.

MCP Server

Once you have an API key, you can set up the MCP server for direct tool access from Claude Code, Cursor, or VS Code. See MCP_SETUP.md.

How It Works

import { SequoiaCodesClient } from "@sequoiaport/codes";

const client = new SequoiaCodesClient({
  apiKey: process.env.SEQUOIA_CODES_API_KEY!,
});

Available Operations

client.snomed.searchCode({ query, limit? })

Hybrid search for SNOMED CT concepts.

const results = await client.snomed.searchCode({
  query: "congestive heart failure",
  limit: 10,
});
// results.results → [{ concept_id, fsn, preferred_term, semantic_tag, similarity, icd10_codes, ... }]

client.snomed.identifyCode({ code })

Look up a specific SNOMED concept by concept ID.

const result = await client.snomed.identifyCode({ code: "73211009" });
// result.concept → { concept_id: "73211009", preferred_term: "Diabetes mellitus", semantic_tag: "disorder", ... }

REST API (curl)

Response Fields

Each SNOMED concept includes:

• concept_id - SNOMED CT concept ID
• fsn - Fully Specified Name
• preferred_term - Preferred display term
• semantic_tag - Category (disorder, finding, procedure, etc.)
• definition_status - Primitive or fully defined
• active - Whether concept is active
• similarity - Search relevance score (0-1)
