CMS Provider Data API

Hospital quality ratings, nursing home data, and Medicare coverage. No authentication required.

Data Model

• Dataset — A published dataset (e.g. Hospital General Information, Nursing Home Compare).
• Distribution — Download format for a dataset (CSV, JSON, API endpoint).
• Theme — Category grouping (Hospitals, Nursing Homes, Physicians, Home Health).

Key Datasets

• Hospital General Information — Star ratings, ownership, emergency services, location.
• HCAHPS — Patient satisfaction survey results by hospital.
• Timely and Effective Care — Quality measures (heart attack, pneumonia, surgical care).
• Complications and Deaths — Readmission and mortality rates.
• Nursing Home Compare — Quality ratings, staffing, health inspections for nursing homes.
• Physician Compare — Individual physician data, specialties, group practices.

Metastore API

• /metastore/schemas/dataset/items — List all available datasets with metadata.
• /metastore/schemas/dataset/items/{id} — Single dataset details.
• Datasets have identifier, title, description, modified, and distribution arrays.

Gotchas

• The metastore API lists datasets; actual data downloads use distribution URLs.
• Star ratings range from 1-5 (5 = best); some hospitals are "Not Available".
• HCAHPS scores are percentages (top-box, middle-box, bottom-box responses).
• Provider data is updated quarterly; check modified dates.
• Blue Button API (beneficiary claims data) requires separate OAuth registration.
