Healthcare Providers in MA

DocTransparency publishes federal Medicare claims, Open Payments industry transfers, and PECOS enrollment records for every healthcare provider with an active National Provider Identifier (NPI) practicing in Massachusetts. This page summarizes what is currently visible at scale for 215,726 Massachusetts providers and the economic context of the counties where they practice.

Provider coverage

215,726 providers have records in our database for Massachusetts. The data is sourced from CMS Open Payments, Medicare Physician & Other Practitioners Public Use File, NPPES, and the OIG List of Excluded Individuals and Entities. We do not include user-generated reviews, ratings, or commentary — only verifiable federal records.

The top specialties by provider count in Massachusetts are:

• Mental Health Counselor: 17,712 providers
• Clinical Social Worker: 16,623 providers
• Student in an Organized Health Care Education/Training Program: 13,295 providers
• Behavior Technician: 10,574 providers
• Counselor: 9,279 providers

These rankings reflect raw provider counts, not quality or volume of care. A specialty appearing high on this list means there are more providers registered in Massachusetts; it does not mean those providers receive higher Medicare payments or industry transfers than peers elsewhere.

Economic context

Massachusetts county-level demographics from the 2022 American Community Survey (5-year):

• Total county population covered: 6,984,205
• Median household income: $98,751
• Poverty rate (B17001): 10.0%
• Adults with bachelor's degree or higher (B15003): 45.9%
• Uninsured rate (B27001): 2.7%
• Unemployment rate (B23025): 5.3%

We surface these indicators alongside provider data because healthcare access correlates with local economic conditions. A county with high poverty and low insurance coverage may have provider patterns (specialty mix, Medicare reliance, payment distributions) that differ materially from a wealthier county in the same state.

What you can do with this data

For each Massachusetts provider profile, we publish: NPI, specialty, practice address, Medicare submitted charges and beneficiary counts, Open Payments industry transfers broken down by manufacturer and payment category, PECOS enrollment status, and OIG exclusion status. We provide canonical URLs, structured JSON-LD metadata, and a sitemap index for crawlers. We do not sell access and do not accept payment from providers to remove or modify profile content. Starting 2026-08-08, the site carries standard programmatic display advertising (Google AdSense), unrelated to any specific profile — see Trust.

Methodology and limitations

Our methodology is documented in full at /methodology. Key caveats specific to Massachusetts:

• State board license verification is currently only available for Florida providers. Massachusetts medical board records are published separately by the Massachusetts licensing authority and we have not yet integrated them.
• Payment dollar amounts are reported as published by CMS; we do not adjust for inflation or specialty norms.
• A provider listed as PECOS-enrolled but without Medicare claims or Open Payments is shown with a minimal record because the federal claims dataset has no additional public information for that NPI.
