Hyperbaric Oxygen Therapy in Illinois: How to Find a Provider

Hyperbaric oxygen therapy (HBOT) is available across Illinois at hospital-based wound care centers, academic medical centers, and standalone hyperbaric clinics.

Here’s how to find an accredited provider near you.

Where to Find HBOT in Illinois

Illinois has a strong medical HBOT infrastructure, particularly in the Chicago metro area.

Hospital-based wound care centers are the most common HBOT option in Illinois. They’re affiliated with regional hospitals, staffed by hyperbaric-certified physicians, and typically covered by Medicare and commercial insurance for FDA-approved conditions.

Academic medical centers in Chicago have some of the most established hyperbaric medicine programs in the Midwest. University-affiliated hospitals treat complex wound care cases and other FDA-approved indications.

Standalone clinics operate in the Chicago suburbs and some downstate areas. Verify physician oversight and chamber pressure ratings before booking. Not all clinics in Illinois are medically supervised.
