ANSWERS "does Medicare cover X" / "is X covered by Medicare" / "what is Medicare's coverage policy for X" — searches current Medicare National Coverage Determinations (NCDs), the national policy documents that say whether Medicare covers a drug, device, procedure or therapy. Search by everyday prod…
medicare_ncd_detail
Retrieve one official Medicare National Coverage Determination by CMS document ID and optional version, including covered indications, limitations, effective dates, benefit category, and revision text.
medicare_lcd_search
Search current final Medicare Local Coverage Determinations (LCDs), optionally restricted to a state. LCDs are contractor- and jurisdiction-specific and can differ across locations.
medicare_lcd_detail
Retrieve one Medicare LCD by document ID and version. Detailed LCD text requires a CMS license-agreement bearer token because documents may contain licensed AMA/ADA/AHA material; pass _licenseToken obtained directly from CMS after accepting those terms.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Medicare Coverage is categorized under Developer Tools and uses a remote streaming HTTP/SSE transport. In contrast, Kernel MCP Server belongs to Developer Tools using local stdio subprocess. Select Medicare Coverage when you need capabilities focused on developer tools and Kernel MCP Server when you require tools for developer tools.
Search National Coverage Analyses (NCAs) and Coverage Analyses for Labs (CALs), including open and completed CMS evidence reviews. An open analysis is a policy process, not a coverage decision.
medicare_nca_detail
Retrieve one CMS National Coverage Analysis by document ID, including request, issue, benefit category, dates, decision memo, and public-comment status when supplied by CMS.
medicare_recent_coverage_changes
Recently published or updated national Medicare coverage documents from CMS, including NCDs, NCAs, CALs, MEDCAC meetings, and technology assessments.
medicare_coverage_states
List CMS Coverage API state identifiers used to scope local Medicare coverage searches.
medicare_article_code_profile
Retrieve one CMS Medicare Coverage Article with its CPT/HCPCS codes and contractor records. Licensed AMA/ADA/AHA content requires a caller-provided CMS license token. Code inclusion describes billing guidance, not guaranteed coverage or payment.
medicare_local_coverage_variation
Compare final LCD search matches across 1–15 states and Medicare Administrative Contractors. Different matching document counts or titles are policy signals, not proof of unequal beneficiary access or payment.
medicare_coverage_timeline
Retrieve official CMS version or revision history for a Medicare NCD, NCA, CAL, or LCD. Accepts either identifier CMS publishes for a coverage document: the public one that appears in the policy text and in every citation of it — an NCD section number such as 310.1 or 90.2, an NCA/CAL tracking numb…
medicare_hcpcs_utilization_trend
Show annual Medicare Physician & Other Practitioners national utilization and payment metrics for one HCPCS code. Claims are fee-for-service aggregates with suppression and methodology limits; they do not measure total US use, coverage, demand, or company revenue.
