medcode_get_code
ActiveTool of io.github.cyanheads/medical-codes-mcp-server
Decode one or more US medical codes to their official descriptions across ICD-10-CM (diagnoses), ICD-10-PCS (inpatient procedures), HCPCS Level II (supplies/drugs/services), and RxNorm (drugs, by RXCUI). Also decodes a National Drug Code (NDC) — hyphenated or 10/11-digit — directly to its RxNorm product offline, tagged `source: "NDC"`. Auto-detects the system from each code's shape; pass an explicit `system` only when a value is genuinely ambiguous. Accepts 1–50 codes and returns partial success: resolved codes in `found`, unresolved in `notFound` with a per-code reason, so one bad code never fails the batch. Set `includeHierarchy` to attach each code's parent and immediate children. The resolved `system` is echoed on every result for chaining into medcode_map_codes or a billability check.
