The Massachusetts provider counts use the CMS NPPES supply-by-state snapshot dated 2026-05-06 – 2026-05-07, under methodology nppes-supply-by-state/v2026.05. That page snapshot is not a claim of current NPPES or Care Compare coverage; source and date fields vary by section.

How Massachusetts provider data is built

Provider counts aggregate the CMS NPPES supply-by-state datasets under methodology nppes-supply-by-state/v2026.05; facility counts read the latest CMS Care Compare snapshots; HPSA and exclusion figures draw from HRSA and OIG / state Medicaid sources. Supported values display the available source name, snapshot date, and methodology version.

Fonteum is a public-records evidence platform covering US, UK & Australia public records, plus global sanctions and entity identifiers, spanning healthcare, federal procurement, sanctions and watchlists, federal enforcement, intellectual property, securities filings, and global company registers. Production registry status is reported separately from loaded and fresh coverage. Dated platform counts come from the public platform-stats snapshot; source-file hashes are reported where present, and deterministic fact-to-signature linkage is not claimed.

Integrated, with-data, and fresh-observation counts are separate. No platform-wide source-completeness count is published. Completeness is source-specific and must be evaluated against the named source's expected scope. State coverage is a separate jurisdiction measure.

Source authority is record-specific

Use the issuer named on the record.

Fonteum spans federal, state, and global public publishers. A source page or returned record identifies its issuer and dataset where that metadata is available. A platform registry count does not assign every page to one authority or establish loaded, fresh, or complete coverage.

Reproducible by design

Inspect the evidence each published figure actually supplies.

Source and date

Research pages expose the named public file and observation date where those fields are available. Source-file SHA-256 coverage is separate; facts do not currently link deterministically to signatures.

Available derivation

Studies with a retained release and committed derivation link the SQL or method used. Other studies state the evidence and reproduction limits they actually have.

Daily observations

Dated table row-count observations can detect local drift. They do not imply that an upstream publisher released or Fonteum ingested new data that day.
