Is Healthgrades data based on NPPES?

Healthgrades uses NPPES data as one input for provider identity (NPI, name, address, taxonomy) but layers patient reviews, insurance network information, and state licensing data on top. The underlying federal identity layer is NPPES; the consumer-facing product adds review and profile layers that are not in NPPES.

Which is more accurate for provider address and specialty?

NPPES is the authoritative federal record for both. Healthgrades refreshes provider profiles at its own cadence from multiple sources; for regulatory or billing purposes, NPPES is always the primary source. Specialty on NPPES is self-reported at NPI enumeration time, which can be out of date — the same limitation applies to Healthgrades.

Can NPPES replace Healthgrades for a patient-facing application?

Only partially. NPPES provides the identity record and taxonomy but has no patient reviews, no ratings, and no insurance-network filters. A patient-facing application that needs review sentiment needs a platform like Healthgrades or a similar consumer review source on top of the NPPES identity layer.

What fields does Fonteum surface from NPPES?

Fonteum surfaces NPI (10-digit identifier), taxonomy code, taxonomy description (e.g., Dermatology, MOHS-Micrographic Surgery), and NPI enumeration date. Each field carries source attribution, last-checked date, and the applicable limitation. Fields are cross-resolved against PECOS, OIG LEIE, and Care Compare on the shared NPI backbone.

NPPES (CMS NPI Registry) vs Healthgrades: Side-by-Side Comparison

NPPES is the federal authoritative record for U.S. healthcare provider identity — the NPI, taxonomy, and address data that underlies all HIPAA billing. Healthgrades is a consumer-facing doctor-rating platform built on patient reviews and provider-submitted profiles. They serve fundamentally different audiences: NPPES is a regulatory data system; Healthgrades is a consumer discovery tool.
