medical-codes-mcp-server

Offline US healthcare code lookup and crosswalk over a bundled SQLite index — keyless, no rate limit, deterministic. Bundled systems: ICD-10-CM (diagnoses), ICD-10-PCS (inpatient procedures), HCPCS Level II (supplies/drugs/services), and RxNorm drugs (the current normalized set). Decode a code with medcode_get_code (the 80% entry point; accepts a batch, auto-detects the system per code, and decodes an NDC directly to its RxNorm product). Go description → code with medcode_search_codes. Validate billability with medcode_check_code — a non-billable or terminated code is a successful result with a whyNot, not an error. Walk the hierarchy with medcode_browse_hierarchy (prefix for ICD-10-CM/HCPCS, axis-based for ICD-10-PCS). Crosswalk with medcode_map_codes — code parents/children, plus the RxNorm drug directions (drug name → RXCUI, NDC ↔ RXCUI, RXCUI → ingredients/brands). Confirm which release is active with medcode_list_systems. ICD-10-CM/PCS are the US clinical modificatio
