HBOT & Diabetes — Your Top Questions Answered

For many people living with diabetes, Hyperbaric Oxygen Therapy (HBOT) sounds promising, but the details can be confusing. Does it really help wounds? How long are the sessions? What oxygen levels are used? And will insurance cover it?

This guide answers the most common patient questions about HBOT and diabetes, based on current research, insurance guidelines, and clinical practice.

HBOT involves sitting or lying in a pressurized chamber while breathing oxygen at levels higher than normal air. Under pressure, oxygen dissolves more efficiently into the blood and tissues, which can accelerate healing, reduce infection, and improve circulation.

For diabetes patients — especially those with chronic foot ulcers or circulation problems — this extra oxygen can be life-changing.

1. Does HBOT really help diabetic wounds?
   

   Yes. HBOT is FDA-approved for non-healing diabetic foot ulcers. Evidence shows it promotes wound closure, lowers infection risk, and reduces amputations.

2. How long is each HBOT session?
   

   Sessions generally last 30 minutes to 2 hours, with 90 minutes being most common. Duration depends on the wound, patient health, and type of chamber used. 

3. How many treatments will I need?

   • Early improvements may appear after 5–10 sessions.
   • Most hyperbaric oxygen treatment courses include 20–40 sessions (often 5 per week).
   • Some diabetic patients continue with weekly or monthly maintenance sessions for long-term benefits. 

4. What oxygen level and pressure are used?

   • HBOT can begin at 1.3 ATA (“mild” HBOT) and go up to 2.5 ATA in clinical settings.
   • For diabetic wounds, treatment typically occurs at 2.0–2.5 ATA, depending on insurance coverage and medical need.
   • Oxygen concentration is usually close to 100%, though delivery method (mask vs. monoplace chamber) may vary.
   • Insurance often requires specific documentation of pressure and oxygen concentration for reimbursement.

5. Is HBOT covered by insurance or Medicare?
   

   Yes, but with conditions:

   • Medicare and most insurers cover HBOT for non-healing diabetic foot ulcers that don’t improve after standard care.
   • Coverage may require proof of wound severity (e.g., Wagner grade) and strict session documentation.

6. Is HBOT safe for diabetics?
   

   Yes, under medical supervision.

   • Most common side effect: mild ear pressure (like flying).
   • Serious side effects are rare and carefully monitored.

7. Does HBOT cure diabetes?
   

   No. HBOT does not cure diabetes. It is an adjunctive therapy that helps manage complications such as slow-healing wounds, infections, and circulation issues. Patients should continue their doctor’s care plan.
   

8. What research supports HBOT?
   

   Cochrane Review: HBOT accelerates wound healing in diabetic foot ulcers.
   Undersea & Hyperbaric Medical Society (UHMS): Recommends HBOT for non-healing diabetic ulcers.
   American Diabetes Association (ADA): Notes HBOT may help in severe, non-healing cases.
   CMS (Medicare): Covers HBOT when criteria are met, including specific pressure and oxygen delivery requirements.

• • Sessions last 30–120 minutes
  • Full course = 20–40 treatments
  • Pressure: 1.3–2.5 ATA
  • Oxygen: usually near 100%
  • Covered by Medicare/insurance (if criteria met)
  • Helps prevent amputations
