Registry provenance
How this entry was verified
live CapabilityStatement fetch (fhirVersion 4.0.1, 144 resource types). The CapabilityStatement names the vendor, not the plan: publisher '1upHealth', software '1up FHIR Server'. Attribution to Health Plan of San Mateo rests on the plan printing this base URL on its own site, at https://www.hpsm.org/about-us/data-interoperability/app-developer-resources, under the heading 'Available Patient Access and Provider Directory API Endpoints'. The same base URL appears in ONC's Lantern export via the 1upHealth endpoint directory. One base serves both surfaces per the plan's own heading (recorded 2026-08-07)
