medcode_list_systems

Tool of io.github.cyanheads/medical-codes-mcp-server

List the bundled US medical code systems with their release identifiers, effective dates, and code counts. Confirms which ICD-10-CM fiscal year, ICD-10-PCS fiscal year, HCPCS Level II release, and RxNorm Prescribable Content snapshot are active before acting on any decode, search, or crosswalk result. The corpus is offline and built at package-build time — this call reports exactly which release is baked into the running server. ICD-10-CM/PCS are the US clinical modifications, not the ICD-10/ICD-11 base.
