Hyperbaric Oxygen Therapy (HBOT) for long COVID costs $150-400 per session at independent clinics, with a standard 40-session protocol totaling $6,000-$16,000 out of pocket. Insurance does not cover it. Long COVID is not among the 15 conditions Medicare and private insurers approve for HBOT reimbursement, and no FDA coverage determination for this indication is expected before 2027 at the earliest.
What Does HBOT for Long COVID Actually Cost?
The price depends on three variables: chamber type, facility setting, and session count. Understanding each variable helps you estimate total cost before committing to treatment.
Per-Session Costs by Facility Type
Independent clinic, hard chamber (2.0 ATA): $150-$400 per session. This is the setting used in most positive clinical trials and where most long COVID patients receive treatment. Mid-range clinics in suburban areas typically charge $200-$300. Urban clinics in major cities (New York, Los Angeles, Miami) often charge $350-$500+. The variance reflects real estate costs and local market competition more than differences in treatment quality.
Hospital outpatient program: $400-$650 per session. Higher due to facility overhead, staffing requirements, and hospital billing structures. Hospital bills can exceed $1,000-$2,500 when facility fees are included, but this scenario is uncommon for long COVID since hospitals typically only offer HBOT for the 15 FDA-cleared indications. A few academic medical centers offer off-label HBOT as part of research programs or long COVID clinics.
Soft chamber wellness studio (1.3 ATA): $50-$100 per session. Important caveat: all positive long COVID trials used hard chambers at 2.0+ ATA with 100% oxygen. Soft chambers operate at lower pressure with ambient air and have not been studied for long COVID. Paying less per session for an untested chamber type is not a cost saving. It is a different, unproven treatment.
Total Protocol Costs
Based on the clinical trial protocols that showed benefit:
- 40 sessions at $150/session: $6,000 (best-case clinic pricing or package deal)
- 40 sessions at $250/session: $10,000 (mid-range independent clinic)
- 40 sessions at $400/session: $16,000 (premium urban clinic)
- 60 sessions at $250/session: $15,000 (extended protocol, mid-range)
- 60 sessions at $400/session: $24,000 (extended protocol, premium)
Package deals reduce these totals meaningfully. Multi-session packages of 10-40 sessions typically save 5-15% off the single-session rate. Monthly memberships at some clinics bring per-session cost to $108-$150. A 40-session package with a 15% discount at a $250/session clinic drops from $10,000 to $8,5001.
Hidden Costs to Budget For
The session fee is not the only expense. Factor in:
- Initial consultation: $100-$300 (some clinics waive this with a package purchase)
- Transportation: Five trips per week for 8 weeks. Gas, parking, or rideshare costs add up, especially if the nearest HBOT clinic is 30+ minutes away
- Lost income: Sessions take 90-120 minutes including preparation and recovery. Five days/week for 8 weeks means significant time commitment. Some patients need to reduce work hours during treatment
- Follow-up imaging: Brain MRI or perfusion studies to assess progress may be recommended by some clinics. Cost: $500-$2,500 depending on type and insurance coverage for the scan itself
Why Insurance Won’t Cover HBOT for Long COVID
Medicare Part B covers HBOT for 15 specific medical conditions, including diabetic foot ulcers (Wagner grade III+), radiation necrosis, carbon monoxide poisoning, decompression sickness, gas gangrene, and compromised skin grafts. Most private insurers (UnitedHealthcare, Aetna, Blue Cross, Cigna) follow Medicare’s coverage list2.
Long COVID is not on the list. Neither are other common off-label HBOT uses like traumatic brain injury, autism, sports recovery, or anti-aging. Even though 10 RCTs and 8 systematic reviews now support HBOT for long COVID, insurance coverage decisions are regulatory, not scientific3.
What would need to happen for coverage:
- A formal National Coverage Determination (NCD) application to CMS (Centers for Medicare and Medicaid Services)
- CMS review of the evidence, which typically takes 12-24 months
- A positive coverage decision from CMS
- Private insurers would then likely follow Medicare’s lead
As of mid-2026, no NCD application for long COVID HBOT has been filed. The UHMS (Undersea and Hyperbaric Medical Society) and patient advocacy groups are working toward this, but the timeline is uncertain. Realistically, insurance coverage for HBOT for long COVID is unlikely before 2028.
This means every payment option described below is out of pocket.
What Do Clinical Studies Show?
Enrolling in a clinical trial is the only way to receive HBOT for long COVID at no cost. Trials cover all session fees and often include imaging, bloodwork, cognitive testing, and follow-up assessments that would otherwise cost thousands.
Where to find active trials:
- ClinicalTrials.gov: Search “hyperbaric oxygen long COVID” for currently recruiting studies. Filter by “Recruiting” status and your geographic area.
- UHMS (Undersea and Hyperbaric Medical Society): Lists affiliated research centers that conduct HBOT trials
- Individual hospital websites: Academic medical centers with HBOT departments sometimes run trials that are not yet listed on ClinicalTrials.gov
What to expect from a trial: Most long COVID HBOT trials require participants to be at least 3 months post-infection with documented symptoms. You will undergo screening assessments (cognitive testing, questionnaires, possibly imaging). Trials are typically sham-controlled, meaning you have a 50% chance of receiving a placebo treatment (room air at minimal pressure with simulated pressurization sounds). You will not know which group you are in until the trial ends. This is the tradeoff: free treatment, but no guarantee you get the active intervention.
Crossover option: Some trials offer a crossover design where sham group participants receive the active HBOT treatment after the initial trial period ends. Ask about this when screening.
Financial Assistance and Payment Options
HSA/FSA accounts. HBOT sessions at a licensed medical facility typically qualify as a medical expense for Health Savings Account (HSA) and Flexible Spending Account (FSA) reimbursement. This effectively reduces cost by your marginal tax rate (22-37% for most patients in the income bracket considering this treatment). A $10,000 protocol becomes $6,300-$7,800 after tax savings. Confirm eligibility with your HSA/FSA administrator. Keep receipts and a letter from the prescribing physician documenting medical necessity.
Payment plans. Many HBOT clinics offer 6-12 month payment plans. Some partner with medical financing companies like CareCredit, Prosper Healthcare Lending, or United Medical Credit. Interest rates range from 0% (promotional periods of 6-12 months) to 15-25% APR after the promotional period ends. A $10,000 protocol at 0% over 12 months is $833/month. At 18% APR over 24 months, the total cost rises to approximately $11,900.
Clinic package pricing. Buying 20-40 sessions upfront saves 5-15%. Some clinics offer a “full protocol” package at a 15-20% discount. Always negotiate. The per-session price at most independent clinics is not fixed. If you call three clinics in your area, you will get three different prices, often with room for negotiation on the highest quote.
Crowdfunding. GoFundMe campaigns for medical HBOT treatment have become common, particularly for long COVID patients. Success varies, but campaigns that include documentation of the patient’s condition, specific treatment plan, cost breakdown, and the supporting clinical evidence tend to perform better. Average medical crowdfunding campaigns raise $2,000-$5,000, which may cover a significant portion of a 40-session protocol at a lower-cost clinic.
Medical credit cards. CareCredit and similar medical credit cards offer 0% promotional periods (typically 6, 12, or 24 months) for qualified applicants. This effectively makes HBOT interest-free if you can pay off the balance within the promotional window. Apply before starting treatment, as approval amounts vary.
Home Chambers: A Cheaper Alternative?
Home soft chambers cost $3,500-$15,000 to purchase. This seems attractive compared to $6,000-$16,000 for clinic sessions. But there is a critical problem.
Every positive long COVID trial used hard chambers at 2.0 ATA with 100% medical-grade oxygen. Soft chambers operate at 1.3 ATA maximum with ambient air (21% oxygen) or oxygen concentrator (~90-95% via mask). The arterial oxygen difference is approximately 8x: ~230 mmHg in a soft chamber versus ~1,824 mmHg in a hard chamber at 2.4 ATA4.
No study has tested soft chambers for long COVID specifically. The two 10-session studies that found no benefit for long COVID used hard chambers with adequate oxygen delivery. Using a soft chamber with lower pressure and lower oxygen delivery has even less evidentiary support. The UHMS has issued a formal consumer warning about soft chambers, noting they are FDA-cleared only for acute mountain sickness.
Where a home chamber may make sense: As a maintenance tool after completing a full clinical protocol at a hard chamber facility. Some patients use home soft chambers for ongoing sessions after their initial 40-session course, on the theory that periodic mild pressurization may help maintain gains. This is based on clinical anecdote, not published trial data. It is not a substitute for the clinical protocol.
Hard chamber home purchase: Hard chambers suitable for home use start at $30,000-$50,000 and require an oxygen supply system, safety protocols, and ideally professional oversight. For patients who need multiple 40-session protocols, purchasing a home hard chamber may become cost-effective after 80-120 sessions (roughly the cost of two clinic-based protocols). This is a significant upfront investment that only makes sense for patients committed to long-term HBOT.
Cost-Effectiveness: Is It Worth It?
This depends on your specific situation. Here is the data to help you decide.
The best-case scenario. You are among the 56-63% of patients who achieve clinically relevant improvement (based on the 232-patient registry). If HBOT restores your cognitive function enough to return to work or resume normal activities, the $6,000-$16,000 investment pays for itself quickly. A patient earning $60,000/year who returns to full-time work 6 months earlier than without treatment gains $30,000 in income, dwarfing the treatment cost5.
The worst-case scenario. You are among the 13-19% who experience worsening symptoms, or the ~20-30% who see no meaningful change. In that case, you have spent thousands on a treatment that did not help. This risk is real and should be factored into the decision.
Comparison with alternatives. Long COVID cognitive rehabilitation programs cost $3,000-$8,000 for a full course. Low-dose naltrexone costs roughly $30-$60/month ($360-$720/year). Stellate ganglion blocks cost $1,000-$3,000 per treatment. None of these alternatives have the same level of RCT evidence as HBOT for long COVID, but they are cheaper. A reasonable approach might be to try lower-cost interventions first and escalate to HBOT if they do not produce sufficient improvement.
The Medicare data as a benchmark. For approved conditions, Medicare pays approximately $23,834 for a 40-session HBOT course (based on 2022 registry data). This suggests that even the insurance system values a 40-session protocol at roughly $24,000 when it does cover it. Patients paying $6,000-$16,000 out of pocket at independent clinics are actually paying less than what Medicare reimburses for the same number of sessions6.
How to Minimize Your Costs
Practical steps based on published pricing data and clinic practices:
- Search ClinicalTrials.gov first. A trial eliminates cost entirely. Even if you receive sham, many trials offer crossover to active treatment.
- Get quotes from 3-5 clinics. Pricing varies significantly even within the same city. A 10-minute phone call to each can save thousands.
- Ask about package deals upfront. A 40-session package should cost 10-20% less than 40 single sessions. If a clinic does not offer packages, ask. Many will create one.
- Use HSA/FSA funds. Tax savings of 22-37% are essentially guaranteed for qualifying expenses at licensed medical facilities.
- Apply for CareCredit or similar. Lock in a 0% promotional period before starting treatment.
- Negotiate. Many clinics will match competitor pricing, offer hardship discounts, or provide a reduced rate for prepayment.
- Consider travel. Clinics in lower-cost areas may charge $150/session vs $400 in your city. An 8-week stay near a cheaper clinic (Airbnb + sessions) may cost less than premium pricing at home.
- Avoid soft chambers as a substitute for the clinical protocol. The evidence does not support soft chambers for long COVID treatment.
