Hyperbaric Oxygen Therapy in Wyoming: How to Find a Provider

Wyoming is the least populous state in the country, and its hyperbaric oxygen therapy options reflect that. In-state hospital-based HBOT is limited. Many Wyoming patients travel to Denver, Salt Lake City, or Billings for a full course of treatment. Knowing which direction to travel before you start is important — it can save you weeks of logistics.

Where to Find HBOT in Wyoming

Hospital-based wound care centers are the most reliable source of accredited HBOT. These programs run under physician supervision, use medical-grade chambers, and work with Medicare and commercial insurers for prior authorization. Wyoming has fewer such programs than most states, which is why out-of-state travel comes up so often.

Wyoming Medical Center in Casper is the largest hospital in the state. It’s the primary referral center for much of central and northern Wyoming. A wound care program at Wyoming Medical Center may offer HBOT or coordinate referrals to facilities in Denver or Billings depending on the specific case and what’s available on-site.

Cheyenne Regional Medical Center serves the state capital and the southeastern corner of Wyoming. Cheyenne is 100 miles north of Denver on I-25, which makes Denver’s major academic medical centers a realistic option for most Cheyenne residents who need HBOT. University of Colorado Hospital and UCHealth in Denver are the primary academic systems that would handle those referrals.

Banner Health operates facilities in Wyoming, including Washakie Medical Center and other smaller hospitals. Banner’s presence in northern Wyoming is limited, but its network connects to larger facilities in neighboring states.

Major Areas in Wyoming and Where to Look for HBOT

Cheyenne is 100 miles from Denver. For most Cheyenne patients, the drive to a Denver-area academic medical center for a multi-week HBOT course is a realistic option. Confirm in-network status with your insurer before traveling.

Casper is the geographic center of the state and home to Wyoming Medical Center. This is the most likely starting point for in-state HBOT referrals for patients in central Wyoming. Patients who can’t be treated locally from Casper often look at Denver (4-5 hours south) or Billings, Montana (4 hours north).

Jackson and Teton County are closer to Salt Lake City than to any major Wyoming city. Patients here typically look at University of Utah Health or Intermountain Health facilities in Salt Lake City for specialized care.

Sheridan and Johnson County in northern Wyoming are less than 2 hours from Billings, Montana. Billings Clinic is the largest healthcare system in Montana and the most realistic option for patients in northern Wyoming seeking HBOT.

Laramie and Albany County are close to Cheyenne and within reach of the Denver metro. University of Wyoming is in Laramie, but the university hospital system is not a major clinical referral center for HBOT.

Rock Springs and Sweetwater County in the southwest are between Salt Lake City and Denver. Either city is a 3-4 hour drive. Your specific insurer’s network will likely determine which direction makes more sense financially.

What to Ask a Potential Provider

Before you book, ask every 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?

Insurance Coverage for HBOT in Wyoming

Coverage for HBOT in Wyoming follows national standards, but out-of-state travel adds complexity.

Medicare Part B covers HBOT for 14 FDA-approved conditions at hospital outpatient facilities anywhere in the country — including Denver, Salt Lake City, and Billings. Rates change annually — verify current figures with your facility’s billing team.

Wyoming Medicaid coverage varies by condition. If you’re being referred out of state, confirm in advance that Wyoming Medicaid will pay for services at an out-of-state facility. This is not automatic and may require prior authorization through your managed care plan.

Commercial insurers generally follow Medicare coverage criteria. Prior authorization is almost always required. Out-of-state referrals add another layer — confirm both that HBOT is covered and that the specific out-of-state facility is in-network before traveling.

Off-label uses are not covered by any insurance in Wyoming or anywhere else.
