Product methodology
Formulary Atlas
Source contract, normalization path, entity-graph join, refresh posture, and publication limits for this Branmoor product.
Status
Pending. This product is pending. The methodology page is published first so the source contract and join path are visible before Branmoor represents the product as live.
Distribution Scope
Nationwide; TN Medicaid/Part D slice; Nashville prescriber/hospital impact
Product Question
Tracks formulary coverage, restrictions, and payer drug access changes.
Primary Sources
- Commercial payer formulary publications — Tier placement, UM constraints, quantity limits, site-of-care
- Medicare Part D formulary files — Plan-level coverage for Part D drugs
- State Medicaid PDLs — Preferred Drug List status by state
- PayerPolicy Watch change feed — Same pipeline, queried by drug rather than by code/policy
Entity-Graph Join
`ndc`/RxCUI, `payer_id`, `npi`, `ccn`, local utilization.
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
Coverage is reconstructed from primary payer documents. Each cell carries a 'last verified' date and a link to the underlying source document.
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.
