Frequently Asked Questions
As of the latest NPPES update, 263 providers in Illinois are registered under taxonomy code 207K00000X (Allergy & Immunology). Of these, 80 (30%) are organizations and 183 (70%) are individual providers. Among the individual providers, 114 are female and 69 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 June 21, 2026. A provider that recently updated their record may take a short time to appear here.
