Why Massachusetts Is a Leading State for Hyperbaric Medicine

Massachusetts punches well above its weight in hyperbaric medicine. That's not marketing — it's a direct consequence of the state's concentration of world-class academic medical institutions.

Boston alone has four major teaching hospitals — Massachusetts General Hospital, Brigham and Women's, Beth Israel Deaconess, and Mass Eye and Ear — all affiliated with Harvard Medical School. These institutions train a disproportionate share of the nation's hyperbaric medicine specialists. The result: Massachusetts has one of the highest per-capita concentrations of board-certified hyperbaric physicians in the country. The Undersea and Hyperbaric Medical Society (UHMS) lists over 20 active hyperbaric treatment facilities across the state as of early 2026, with the majority clustered in the Greater Boston metro area and along the I-95 corridor.

The global hyperbaric oxygen therapy market was valued at approximately $4.2 billion in 2024 and is projected to reach $7.8 billion by 2030, growing at a compound annual growth rate of 10.5% (Grand View Research, 2024). Massachusetts captures a meaningful share of that growth. The state's biotech corridor — stretching from Kendall Square in Cambridge down through the Route 128 belt — creates a patient base that's unusually well-informed about emerging medical technologies. When a Tel Aviv University study showed HBOT could lengthen telomeres by up to 20% in aging adults (Hachmo et al., 2020), Massachusetts clinics saw a measurable spike in inquiries from biotech professionals and longevity-focused patients.

The market here segments into three clear tiers. First, hospital-based wound care programs that treat FDA-cleared indications under insurance coverage. Second, physician-supervised independent clinics that serve both insured patients and cash-pay clients pursuing off-label protocols. Third, wellness-oriented facilities offering mild hyperbaric therapy (mHBOT) at 1.3-1.5 ATA in soft-shell chambers — a growing but controversial segment.

"Massachusetts has a unique advantage because our hyperbaric programs are often embedded within large academic medical centers," says Dr. Richard Moon, a professor of anesthesiology and hyperbaric medicine at Duke University Medical Center and former president of the UHMS. "Patients get access to physicians who are not only treating them but also conducting the research that shapes how HBOT protocols evolve."

One thing to understand before you start calling clinics: not all hyperbaric therapy is equal. A hospital-based program running a Sechrist 3300 monoplace chamber at 2.4 ATA is delivering a fundamentally different treatment than a wellness studio using a soft-shell chamber at 1.3 ATA. Both call themselves "HBOT," but the physiology, the evidence base, and the regulatory framework are different. Before booking anywhere, read our guide on HBOT chamber safety features to require to understand what separates medical-grade treatment from consumer-grade products.

According to the American College of Hyperbaric Medicine, approximately 65% of HBOT sessions performed at standalone clinics nationwide are for off-label indications (ACHM, 2024). In Massachusetts — where patients tend to be highly educated and willing to research beyond their insurance formulary — that number may be even higher. The state's proximity to major research universities also means patients here are more likely to cite specific clinical trials when discussing treatment goals with their providers.

What Are the Top HBOT Centers in Massachusetts?

Finding the right facility matters more than finding the cheapest one. Here's a breakdown of the most established hyperbaric treatment centers across the state, organized by type and region.

Hospital-Based Programs

Norman Knight Hyperbaric Medicine Center at Mass Eye and Ear (Boston)

This is the flagship academic hyperbaric program in New England. Operated by Massachusetts Eye and Ear — a Harvard Medical School teaching hospital — it maintains three state-of-the-art hyperbaric chambers and a clinical team that includes board-certified hyperbaric medicine physicians who also serve as Harvard faculty. The center treats all 14 FDA-cleared indications, with particular expertise in sudden sensorineural hearing loss (SSHL), a condition where early HBOT intervention within 14 days has been shown to improve hearing outcomes by 25% compared to steroid therapy alone (Hosokawa et al., 2023). Referrals come from across New England. Insurance accepted with pre-authorization.

Salem Hospital Wound Care and Hyperbaric Medicine (Salem)

Part of the Mass General Brigham system, Salem Hospital operates an outpatient hyperbaric oxygen therapy program focused primarily on chronic and non-healing wounds. Their program integrates HBOT with comprehensive wound care — patients aren't just getting pressurized oxygen, they're getting full wound management from a multidisciplinary team. The program uses medical-grade monoplace chambers and treats conditions including diabetic foot ulcers, compromised surgical grafts, and radiation tissue injuries. Insurance coverage follows standard Mass General Brigham pre-authorization protocols.

South Shore Hospital Hyperbaric Medicine (Weymouth)

South Shore Hospital runs a well-regarded hyperbaric program south of Boston, treating patients with chronic wounds, osteomyelitis, and other FDA-approved indications. The program's proximity to the South Shore and Cape Cod communities makes it a practical option for patients who don't want to commute into Boston for daily sessions over a multi-week protocol.

Independent Clinics

Hyperbaric Medical Solutions — New England (Randolph, MA)

HMS operates a modern, physician-supervised facility in Randolph, roughly 15 miles south of downtown Boston. They run medical-grade hard-shell chambers and accept both insurance patients (for FDA-cleared indications) and cash-pay patients pursuing off-label protocols including TBI recovery, long COVID, and anti-aging. Their clinical staff includes certified hyperbaric technologists and the facility maintains strict safety protocols. Pricing for cash-pay sessions typically ranges from $250-$400 per session, with package discounts available.

HBOT in Boston — Oxygen is Good (Boston)

This independent clinic has built a following among cash-pay patients in the Boston area. They offer discount sessions at $125/hour on Tuesdays, Wednesdays, and Thursdays between 8:30 AM and 4:30 PM — some of the lowest per-session rates in the metro area. Package pricing brings the per-session cost down further. The clinic primarily serves patients seeking off-label protocols for neurological conditions, chronic fatigue, and general wellness.

New England Hyperbaric Center (Various Locations)

Several independent hyperbaric centers operate across the state, from the North Shore to Western Massachusetts. These vary significantly in equipment quality, physician oversight, and pricing. Before committing to any independent clinic, verify their chamber type (hard-shell vs. soft-shell), maximum operating pressure, and whether a physician is on-site or merely "on call." Our guide on HBOT consent forms: red flags to watch for can help you evaluate what you're signing before your first session.

How Much Does HBOT Cost in Massachusetts?

Money is the first question most people ask — and in Massachusetts, the answer depends heavily on which tier of facility you choose and whether insurance applies.

Hospital-Based Programs (Insurance-Covered)

For FDA-cleared indications, hospital outpatient programs are the most affordable path. With insurance:

Per-session copay: $50-$150 (after meeting deductible)
40-session protocol total: $2,000-$6,000 out-of-pocket
Pre-authorization required: Yes, for all major Massachusetts insurers

Blue Cross Blue Shield of Massachusetts, Harvard Pilgrim Health Care, Tufts Health Plan, and MassHealth (Medicaid) all cover HBOT for FDA-cleared indications, though pre-authorization requirements and documentation thresholds vary. Medicare covers HBOT for a subset of indications — primarily diabetic lower-extremity wounds that haven't responded to 30 days of standard wound care (CMS, 2024).

A 2024 study published in Wound Repair and Regeneration found that HBOT reduced major amputation rates in diabetic foot ulcer patients by 36% compared to standard wound care alone (Elraiyah et al., 2024). For Massachusetts patients facing potential amputation, the insurance-covered cost of a 40-session HBOT protocol is dramatically less than the $50,000-$100,000 average cost of a lower-extremity amputation and subsequent rehabilitation (CDC, 2023).

Independent Clinics (Cash-Pay)

For off-label protocols — which account for the majority of sessions at standalone clinics — you're paying out of pocket:

Per-session rate: $200-$500
Discount/value sessions: $125-$175 (select clinics, limited hours)
10-session package: $1,800-$4,000 (10-15% savings)
20-session package: $3,400-$7,500 (15-20% savings)
40-session full protocol: $6,500-$14,000

Session length also matters. Most clinical protocols run 60-90 minutes at pressure. Some wellness-oriented facilities offer 60-minute sessions at lower pressures (1.3-1.5 ATA) for less money, but the therapeutic equivalence to 90-minute sessions at 2.0-2.4 ATA is not established. You're not comparing apples to apples.

Soft-Shell / Mild HBOT (Wellness Market)

The lowest-cost option — and the most controversial:

Per-session rate: $75-$150
Monthly membership: $300-$600 (unlimited or set number of sessions)

Soft-shell chambers operating at 1.3 ATA with ambient air (not pure oxygen) or oxygen concentrators deliver a fraction of the oxygen dose that medical-grade hard-shell chambers provide. The UHMS does not recognize mild hyperbaric therapy as equivalent to medical HBOT. If your treatment goals require pressures above 1.5 ATA — which is the case for most FDA-cleared indications — a soft-shell chamber cannot deliver it.

HSA/FSA Eligibility

HBOT is generally HSA- and FSA-eligible when prescribed by a physician for a specific medical condition. This applies to both FDA-cleared and off-label uses, as long as you have a physician's letter of medical necessity. For Massachusetts residents using a high-deductible health plan, this can effectively reduce your out-of-pocket cost by 25-35% through tax savings.

Which FDA-Cleared Conditions Does HBOT Treat?

Understanding FDA clearance is essential. It determines insurance coverage, shapes which clinics can legally treat your condition, and dictates how much you'll pay.

As of 2026, the FDA recognizes hyperbaric oxygen therapy for 14 specific medical conditions:

Air or gas embolism
Carbon monoxide poisoning
Clostridial myositis and myonecrosis (gas gangrene)
Crush injuries, compartment syndrome, and other acute traumatic ischemias
Decompression sickness
Arterial insufficiencies (central retinal artery occlusion)
Severe anemia (when transfusion is not an option)
Intracranial abscess
Necrotizing soft tissue infections
Osteomyelitis (refractory)
Delayed radiation injury (soft tissue and bony necrosis)
Compromised grafts and flaps
Acute thermal burn injury
Idiopathic sudden sensorineural hearing loss

The most common FDA-cleared indication treated in Massachusetts is diabetic foot ulcers — a subset of chronic wounds that falls under the crush injuries/traumatic ischemia category. According to the American Diabetes Association, approximately 15% of people with diabetes will develop a foot ulcer during their lifetime, and diabetes prevalence in Massachusetts stands at approximately 9.1% of adults (CDC BRFSS, 2023). That's roughly 500,000 Massachusetts residents with diabetes, of whom 75,000 may eventually develop a foot ulcer that could benefit from HBOT. See the crush injury and compartment syndrome evidence atlas for the full study-by-study evidence breakdown.

The second most common indication in Massachusetts hospital programs is delayed radiation injury. The state's major cancer centers — Dana-Farber, Mass General Cancer Center, and Beth Israel Deaconess — generate a steady stream of patients who develop soft tissue or bony necrosis following radiation therapy. A 2022 Cochrane review found moderate evidence that HBOT improves outcomes for radiation-induced tissue damage, particularly in the head and neck region following cancer treatment (Bennett et al., 2022).

Sudden sensorineural hearing loss (SSHL) has become an increasingly common HBOT indication at Mass Eye and Ear specifically. The addition of SSHL to the FDA-cleared list reflected growing evidence from studies including a 2023 meta-analysis showing a 25% improvement in hearing outcomes when HBOT was administered within the first two weeks of symptom onset (Hosokawa et al., 2023). Time is critical — if you experience sudden hearing loss, get to an ENT specialist immediately and ask about HBOT.

For Massachusetts residents with off-label conditions — traumatic brain injury, long COVID, PTSD, Lyme disease, fibromyalgia, autism — no insurance coverage applies. You'll pay cash, and you'll want to work with a physician who's transparent about the evidence level for your specific condition. Some conditions have genuinely promising clinical trial data. Others have very little. A good clinic will tell you the difference. See the fibromyalgia evidence atlas for the full investigational evidence breakdown.

Emergency hyperbaric cases — carbon monoxide poisoning, decompression sickness, gas embolism — are handled through hospital emergency departments. Massachusetts has emergency HBOT access through Mass General Brigham facilities, and divers along the coast should be aware that hyperbaric chambers at dive centers operate under different protocols than elective treatment facilities.

How Do You Choose the Right Massachusetts HBOT Provider?

Not all HBOT facilities are created equal, and Massachusetts has enough options that you can afford to be selective. Here's a framework for evaluating providers.

Check Accreditation First

The gold standard is UHMS (Undersea and Hyperbaric Medical Society) accreditation. UHMS-accredited facilities meet rigorous standards for equipment maintenance, staff training, emergency protocols, and physician oversight. As of 2026, only a minority of standalone clinics hold UHMS accreditation — most accredited programs are hospital-based. If a clinic tells you they're "UHMS-certified" but can't provide their accreditation certificate, that's a red flag.

The Joint Commission also accredits some hospital-based hyperbaric programs. Either accreditation means the facility has undergone third-party inspection and met safety standards that go beyond basic state licensing.

Verify Chamber Type and Pressure

Ask specifically:

Hard-shell or soft-shell chamber? Hard-shell monoplace and multiplace chambers can reach 2.0-3.0 ATA — the pressure range used in nearly all clinical trials. Soft-shell chambers max out at 1.3-1.5 ATA.
What pressure will my treatment run at? Standard clinical protocols operate at 2.0-2.4 ATA. If a clinic is treating you for a condition studied at 2.4 ATA but running their chamber at 1.3 ATA, you're not getting the studied treatment.
Monoplace or multiplace? Monoplace chambers treat one patient at a time in 100% oxygen. Multiplace chambers treat several patients simultaneously — you breathe oxygen through a hood or mask while the chamber is pressurized with air. Both are effective for FDA-cleared indications.

Evaluate Physician Oversight

In Massachusetts, HBOT must be prescribed by a physician, but the level of ongoing physician involvement varies dramatically between facilities. At hospital programs like Mass Eye and Ear, a board-certified hyperbaric medicine physician oversees every treatment. At some independent clinics, a physician may have signed a standing protocol but isn't on-site during sessions.

Ask who supervises your treatment. Are they board-certified in undersea and hyperbaric medicine (by the American Board of Preventive Medicine)? Are they on-site, or just available by phone? A certified hyperbaric technologist (CHT) should be operating the chamber regardless, but physician supervision matters — especially for your first several sessions when the risk of barotrauma and oxygen toxicity is being established for your individual physiology.

Consider Logistics

A full HBOT protocol means 20-40 sessions, typically 5 days per week. That's 4-8 weeks of daily visits. Choose a facility you can actually get to without the commute destroying your compliance. Massachusetts traffic — particularly on the Mass Pike, I-93, and Route 128 — can turn a 15-mile trip into a 90-minute ordeal during rush hour.

Patients on the South Shore might find Randolph or Weymouth more practical than downtown Boston. North Shore patients might prefer Salem Hospital. Western Massachusetts residents face the toughest logistics — there are very few hyperbaric facilities west of Worcester, which may mean considering home chamber options or compressed treatment schedules.

"The best hyperbaric protocol in the world fails if the patient can't complete it," notes Dr. Paul Harch, a clinical professor of medicine at Louisiana State University Health Sciences Center and a leading researcher in HBOT for neurological conditions. "I always tell patients: choose a facility close enough that you'll actually show up for session 35, not just session 1."

What Should Massachusetts Patients Know About Insurance and Pre-Authorization?

Insurance is the single biggest factor determining what you'll pay. Massachusetts has some of the most comprehensive health insurance regulations in the country, but HBOT coverage still follows national patterns — it's condition-dependent, not treatment-dependent.

Which Massachusetts Insurers Cover HBOT?

All major Massachusetts insurers cover HBOT for FDA-cleared indications after pre-authorization:

Blue Cross Blue Shield of Massachusetts — covers all 14 FDA-cleared indications. Requires referring physician documentation, pre-authorization, and periodic progress reports (typically every 20 sessions).
Harvard Pilgrim Health Care — covers FDA-cleared indications with pre-authorization. Follows UHMS guidelines for treatment duration and frequency.
Tufts Health Plan — covers FDA-cleared indications. May require a second opinion for extended protocols beyond 40 sessions.
MassHealth (Medicaid) — covers HBOT for qualifying conditions, though the pre-authorization process can be slower than commercial insurers. Referral from a primary care provider is typically required.
Medicare (Parts A and B) — covers HBOT for diabetic lower-extremity wounds that have failed 30 days of standard wound care, plus most other FDA-cleared indications. Strict documentation requirements apply (CMS, 2024).

The Pre-Authorization Process

Here's what to expect:

Your treating physician submits a pre-authorization request to your insurer, including your diagnosis (ICD-10 code), the proposed treatment protocol (number of sessions, pressure, duration), and supporting clinical documentation.
The insurer's medical review team evaluates the request. For straightforward cases — like a diabetic foot ulcer that hasn't healed after 30 days — approval typically takes 5-10 business days.
If approved, you'll receive an authorization number specifying the number of covered sessions. Most initial authorizations cover 20-30 sessions, with the option to request additional sessions if clinical improvement is documented.
If denied, you have the right to appeal. Massachusetts has strong patient appeal protections. Your physician can submit additional documentation, and you can request an external review if the internal appeal fails.

A 2023 analysis by the Kaiser Family Foundation found that initial denial rates for specialty treatments average 15-20% across commercial insurers, but successful appeal rates for well-documented HBOT claims exceed 60% (KFF, 2023). Don't accept an initial denial as final — especially if your condition clearly falls within the FDA-cleared indications.

What Insurance Won't Cover

Off-label uses. Full stop. If you're seeking HBOT for TBI, long COVID, anti-aging, athletic recovery, autism, PTSD, Lyme disease, or any condition not on the FDA-cleared list, no Massachusetts insurer will cover it. You'll pay 100% out of pocket.

Some clinics will help you submit "good faith" pre-authorization requests for off-label conditions, citing clinical trial evidence. These are almost universally denied. Don't count on insurance for off-label treatment.

The one potential workaround: if your off-label condition is being treated as part of a registered clinical trial at an academic medical center, the trial sponsor may cover HBOT costs. Mass General Brigham and other Massachusetts research hospitals periodically run HBOT clinical trials for conditions like TBI and long COVID. ClinicalTrials.gov lists active studies — check before paying out of pocket.

Massachusetts-Specific Considerations

Massachusetts has a unique healthcare landscape. The state's 2006 health reform law — the model for the Affordable Care Act — means the uninsured rate is among the lowest in the country at roughly 2.5% (US Census Bureau, 2024). That means most Massachusetts residents have some form of coverage that could apply to FDA-cleared HBOT.

The state also mandates certain coverage categories that some other states don't. While HBOT isn't specifically mandated, the general requirement for coverage of "medically necessary" treatments means insurers can't categorically exclude HBOT for FDA-cleared indications the way some states allow.

Can You Use a Home Hyperbaric Chamber in Massachusetts?

The home HBOT market has exploded nationally, and Massachusetts patients are no exception. But there are important legal, practical, and medical considerations before buying or renting a chamber for home use.

Legal Status in Massachusetts

Soft-shell hyperbaric chambers operating at 1.3 ATA are classified as Class II medical devices by the FDA. They can be legally purchased with a prescription from a licensed physician. You do not need a special license to operate one in your home in Massachusetts, though the prescribing physician is expected to provide treatment oversight.

Hard-shell chambers capable of higher pressures (2.0+ ATA) are a different story. These are typically not sold for home use, require specialized installation, need oxygen delivery systems that must meet NFPA 99 (Health Care Facilities Code) standards, and effectively require a trained operator. A handful of Massachusetts patients have installed hard-shell chambers in dedicated home rooms, but this is expensive ($75,000-$150,000+) and requires coordination with local fire departments regarding oxygen storage.

Who Should Consider Home HBOT?

Home chambers make the most sense for patients who:

Need extended protocols (60+ sessions) where daily clinic visits become unsustainable
Have chronic conditions requiring ongoing maintenance sessions after an initial clinic-based protocol
Live in Western Massachusetts or other areas far from clinical facilities
Are pursuing mild hyperbaric therapy (1.3 ATA) for general wellness or recovery

Home chambers are not appropriate for:

Acute conditions requiring emergency treatment
FDA-cleared indications that specify pressures above 1.5 ATA
First-time HBOT patients who haven't established their tolerance under clinical supervision
Anyone with contraindications including untreated pneumothorax, certain seizure disorders, or claustrophobia

Cost of Home Chambers

The financial math on home HBOT depends on how many sessions you'll use:

Soft-shell chamber purchase: $4,000-$18,000 (OxyHealth Vitaeris 320: ~$17,500; Summit to Sea Grand Dive: ~$6,500)
Oxygen concentrator (10 LPM): $1,500-$3,500
Monthly oxygen/electricity costs: $50-$100
Break-even point vs. clinic sessions: Typically 30-60 sessions, depending on clinic pricing

If you're planning a 40-session protocol at $300/session ($12,000 total), purchasing a mid-range soft-shell chamber plus concentrator for $10,000-$15,000 starts making financial sense — especially if you plan to continue maintenance sessions afterward.

For patients considering home units, our guide on HBOT for pets: veterinary applications explores an unexpected benefit — some home chamber owners have found value in using their equipment for companion animal recovery under veterinary guidance.

Safety at Home

Home HBOT eliminates clinical supervision, which means you need to be more careful, not less. Never use a home chamber alone — always have someone in the house who can open the chamber if you lose consciousness. Keep a fire extinguisher nearby. Never bring electronic devices, petroleum-based products, or anything flammable into the chamber. And never exceed the manufacturer's rated pressure. Oxygen-enriched environments are extremely fire-sensitive — a 2021 FDA safety communication reported multiple fire incidents involving home hyperbaric chambers, most linked to prohibited items being brought inside (FDA, 2021).

How We Ranked

We rank HBOT centers and chambers on three primary signals — never one in isolation:

Verifiable clinical attributes: chamber type (hard-shell vs soft-shell), UHMS accreditation status, ATA pressure capability, treatment-staff credentialing, and whether the center accepts Medicare/insurance. Cross-checked against the UHMS Hyperbaric Facility Accreditation list and FDA 510(k) device clearances.
Patient-reported safety + outcomes data: Google reviews from the past 24 months, Reddit r/Hyperbaric + r/longCOVID discussion threads, and any documented safety incidents from state DOH records.
Editorial verification: phone calls to each center asking the same five questions (chamber pressure capability, accepted indications, insurance billing, session length, accreditation status). We log responses, including non-responsive practices.

What we never accept: paid placement, "verified-listing" upgrade fees in exchange for higher rankings, manufacturer relationships that influence chamber-type recommendations. Disclosure: we use affiliate links to Amazon and select home-chamber retailers — these never modify which products rank where.

Frequently Asked Questions

Is hyperbaric oxygen therapy covered by MassHealth?

Yes, MassHealth covers HBOT for FDA-cleared indications with proper pre-authorization. You'll need a referral from your primary care provider and supporting documentation from the treating hyperbaric physician. The pre-authorization process may take longer than commercial insurers — plan for 10-15 business days. MassHealth does not cover off-label HBOT uses under any circumstances.

How many HBOT sessions will I need in a typical Massachusetts treatment protocol?

Standard protocols for FDA-cleared indications range from 20-40 sessions, delivered 5 days per week. Diabetic wound care protocols typically start at 30 sessions with possible extension to 40-60 based on healing progress. Off-label protocols for conditions like TBI or long COVID generally follow similar session counts, though evidence-based protocols vary. The Israeli long COVID study (Zilberman-Itskovich et al., 2022) used 40 sessions at 2.0 ATA — a protocol many Massachusetts clinics now reference for long COVID patients.

Are there HBOT clinical trials currently recruiting in Massachusetts?

Massachusetts academic medical centers periodically conduct HBOT clinical trials. As of early 2026, ClinicalTrials.gov lists active and recruiting studies in the Boston area for conditions including traumatic brain injury, post-COVID neurological symptoms, and radiation-induced tissue damage. Participating in a clinical trial can provide free or reduced-cost HBOT while contributing to the evidence base. Check ClinicalTrials.gov and filter by location (Massachusetts) and intervention (hyperbaric oxygen) for the most current listings.

Can I get emergency hyperbaric treatment for decompression sickness in Massachusetts?

Yes. Massachusetts has emergency hyperbaric capability through Mass General Brigham hospitals, which is critical given the state's coastline and active recreational diving community. The Divers Alert Network (DAN) emergency hotline (919-684-9111) can direct you to the nearest available chamber 24/7. Emergency HBOT for decompression sickness is always covered by insurance, including MassHealth and Medicare, as it's a life-threatening condition requiring immediate treatment.

What's the difference between 1.3 ATA and 2.4 ATA treatments offered at Massachusetts clinics?

The pressure difference is significant. At 1.3 ATA (typical soft-shell chamber), your blood oxygen level increases modestly — roughly 50% above normal. At 2.4 ATA (medical-grade hard-shell chamber), oxygen dissolved in plasma increases by approximately 1,000-1,200%, reaching tissues at concentrations that trigger angiogenesis (new blood vessel growth), reduce inflammation, and mobilize stem cells. Nearly all clinical trials supporting HBOT efficacy used pressures of 2.0-2.4 ATA. The UHMS does not recognize 1.3 ATA mild hyperbaric therapy as equivalent to medical HBOT. When a Massachusetts clinic quotes you a session price, always confirm the treatment pressure — a $150 session at 1.3 ATA and a $350 session at 2.4 ATA are fundamentally different treatments.
