340B Contract Pharmacy Map
Source contract, normalization path, entity-graph join, refresh posture, and publication limits for this Branmoor product.
Status

Distribution Scope
Nationwide; TN covered entities; Nashville hospital/pharmacy map
Product Question
Maps 340B covered entities, pharmacies, restrictions, and exposure.
Primary Sources
- HRSA OPAIS — Covered entity database, contract pharmacy database, registered relationships
- Manufacturer 340B restriction notices — Active restrictions by manufacturer and product
- CMS Medicare cost reports — DSH percentage, hospital size and case mix
- Federal Register and HRSA dispute postings — Active disputes and policy developments
Entity-Graph Join
340B ID, `ccn`, pharmacy NPI/NCPDP, `irs_ein`, parent entity.
Publication Rule
Branmoor does not treat raw public records as the product. A surface is publishable only when the source record is dated, normalized, source-linked, and joined to the relevant Branmoor entity identifiers with enough confidence to state the limits of the result.
Current Methodology Note
Graph is rebuilt monthly from the OPAIS public extract. Manufacturer restriction overlays carry effective dates and source citations.
Limits
Coverage follows the underlying source. Missing state portals, gated APIs, PDF-only filings, suppressed fields, lagged agency refreshes, and entity-name ambiguity can all limit product completeness. Pending products are not marketed as live until those limits are documented on the product surface.
