Frequently Asked Questions
As of the latest NPPES update, 211 providers in Maryland are registered under taxonomy code 207K00000X (Allergy & Immunology). Of these, 64 (30%) are organizations and 147 (70%) are individual providers. Among the individual providers, 70 are female and 77 are male. The full directory spans 3 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.
