Hyperbaric Oxygen Therapy in Washington State: How to Find a Provider

This page covers Washington State, not Washington D.C. Hyperbaric oxygen therapy (HBOT) is available across Washington State at hospital-based wound care centers, academic medical centers, and standalone clinics. The Seattle metro area has the state’s strongest concentration of medically supervised HBOT programs, with options also available in Spokane and other mid-sized cities. Here’s how to find an accredited provider near you.

Where to Find HBOT in Washington State

Hospital-based wound care centers are Washington’s most common HBOT option. 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 Seattle run nationally recognized programs for complex wounds and other medically indicated HBOT cases.

Standalone clinics operate in several Washington cities, particularly in the Seattle metro. Some focus on wellness applications rather than medical HBOT. Verify physician credentials and chamber pressure ratings before committing. Medical HBOT requires a chamber rated to 2.0 ATA or higher.

The best starting point: use the UHMS provider search at uhms.org. It lists accredited facilities across Washington State.

What to Ask a Potential Provider

Before you book, ask every potential provider these questions.

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

Washington has a notable wellness clinic market, especially in Seattle. The questions above will help you tell a medical program apart from a wellness operation. Read our guide to questions to ask a provider for more detail.
