Hyperbaric Oxygen Therapy in Maryland: How to Find a Provider

Maryland has strong HBOT access, especially in the Baltimore metro and the DC suburbs. The state is home to some of the most recognized academic medical centers in the country. Patients in suburban Maryland also have the option of accessing providers in Washington DC or Northern Virginia.

Where to Find HBOT in Maryland

• Hospital-based wound care centers. These are the most common setting for HBOT. Insurance is most likely to cover FDA-approved conditions here.
• Academic medical centers. Johns Hopkins Medicine and the University of Maryland Medical System are both major academic centers with complex wound care programs.
• Standalone clinics. These exist in the state. Verify credentials and chamber specifications before starting treatment.

The UHMS provider directory at uhms.org/find-a-hyperbaric-facility.html is the best starting point. It lists accredited facilities only.

Major Areas in Maryland Where HBOT Is Available

Baltimore. Baltimore has the highest concentration of HBOT providers in the state. Johns Hopkins Medicine is a nationally recognized academic medical center with expertise in complex wound care and related conditions. The University of Maryland Medical System operates multiple hospitals throughout the city and surrounding counties. MedStar Health also has a significant Baltimore presence.

DC Suburbs (Bethesda, Rockville, Gaithersburg, Silver Spring). The Maryland suburbs of DC are well served by MedStar Health, Holy Cross Health, and University of Maryland Medical System facilities. Some patients in this corridor also access providers in Washington DC itself, depending on insurance network and location.

Columbia and Howard County. Howard County sits between Baltimore and the DC suburbs and is served by hospitals affiliated with major regional systems.

Annapolis and the Eastern Shore. Anne Arundel Medical Center, part of the Luminis Health system, serves the Annapolis area. The Eastern Shore is more rural, and patients there may travel to Baltimore or DC for specialized care. Use the UHMS directory to find the nearest accredited facility.

Frederick and Western Maryland. Frederick Health Hospital serves the Frederick corridor. Patients in western Maryland may need to travel to Baltimore or the DC metro for HBOT programs.

What to Ask a Potential Provider

Ask these five questions before committing to a program:

1. Is this a medical-grade hyperbaric chamber (2.0 ATA or higher)?
2. Is there a board-certified or credentialed hyperbaric physician on staff?
3. Is my condition FDA-approved for HBOT?
4. Does your facility work with my insurance for prior authorization?
5. Is the facility UHMS-accredited?

Our guide to questions to ask a provider explains what each answer tells you about the quality of the program.
