Frequently Asked Questions
As of the latest NPPES update, 668 providers in Massachusetts are registered under taxonomy code 207RH0003X (Internal Medicine Hematology & Oncology). Of these, 68 (10%) are organizations and 600 (90%) are individual providers. Among the individual providers, 244 are female and 356 are male. The full directory spans 7 pages of up to 100 providers each.
Each card shows a PECOS badge based on the CMS Order and Referring dataset. A green PECOS badge means the provider appears in that dataset as eligible to order and refer. Open the provider profile, then verify directly in PECOS before relying on it for claims or credentialing.
The directory is rebuilt from the public NPPES registry, which is refreshed weekly. The NPI data on this page was last updated on July 12, 2026. A provider that recently updated their record may take a short time to appear here.
