Ozone Therapy: What's Covered, the Evidence and What to Check

Ozone therapy - blood infused with ozone gas, or ozone administered by other routes - is sometimes marketed as a fix for everything from diabetic foot to chronic fatigue. Before asking about funding, it's important to understand something fundamental: Israel's Ministry of Health has not approved a defined medical indication for ozone, and it operates in Israel mainly within the framework of complementary medicine under a physician's responsibility, not as a recognized conventional treatment. The practical implication is twofold: both "is this covered" and "is this safe" require caution and independent checking before you start.

What Ozone Therapy Is and How It's Given

Ozone is a reactive form of oxygen (O3), studied for its disinfectant and oxidative properties. In the complementary-medicine context it's administered in several ways: drawing the patient's own blood, treating it with ozone gas, and returning it to the body (major autohemotherapy); local injection; intra-articular treatment; or external use as an oil/cream on wounds and skin.

In Israel, this treatment is offered mainly at private clinics defined as pain medicine or complementary medicine, by physicians who have completed dedicated training in the field - but without official Ministry of Health recognition of any specific clinical indication. It's important to distinguish this from external ozone products (like creams) that have received limited approval as a medical device for localized use - that is not equivalent to approval of systemic ozone treatment.

What the Scientific Evidence Shows - and Why It Matters

Most existing evidence on ozone therapy comes from experimental models, small clinical studies, or observational reports with substantial methodological variability. High-quality randomized controlled trials are few, and the proposed biological rationale has not yet been consistently translated into proven clinical outcomes. The U.S. FDA classified ozone as far back as 1976 as "a toxic gas with no known useful medical application," and issued a public warning against the use of ozone treatments in 2019 - a position shared by most international regulators.

This isn't a semantic point. It means there is currently no scientific-regulatory consensus supporting ozone therapy as a proven treatment for any disease, and any decision to use it should be made with full awareness of that limitation - not with an expectation of a guaranteed medical outcome.

Safety: The Risks Worth Knowing Before You Decide

Ozone therapy has a narrow therapeutic window - incorrect dosing can cause oxidative damage to tissue. One safety point is absolute: injecting ozone gas directly into a vein is contraindicated, because the gas itself can cause a fatal air embolism, and no amount of practitioner training or equipment makes direct intravenous gas administration safe. This is fundamentally different from major autohemotherapy, where blood is drawn, mixed with ozone outside the body, and returned - if a provider offers to inject ozone gas straight into a vein, treat it as a red flag. Air embolism - gas bubbles entering the bloodstream that block blood flow to the brain or other organs - is a rare but life-threatening complication. In addition, ozone damages lung tissue and must never be inhaled directly at high concentrations.

Long-term safety data remain limited - there isn't yet enough information on cumulative oxidative effects, interaction with underlying conditions, or the impact of repeated administration over time. Anyone considering ozone therapy should confirm it is given at a clinic with appropriate equipment and immediate response capability in case of an unexpected reaction, and should disclose it to their treating physician along with any medications or underlying conditions.

Funding Routes Available in Israel

Because there is no official Ministry of Health recognition of ozone therapy as a recognized clinical treatment, it is almost never included in the public health basket delivered through the kupot. Anyone seeking partial funding should check two possible routes: שב"ן, the HMO's supplementary insurance, some of whose plans include a quota for complementary-medicine treatments - though ozone is not a common item on those lists and is often not recognized at all; and a dedicated complementary-medicine service letter, a separate product that expands the recognized-treatment basket and sometimes includes experimental or less common treatments - but again, subject to that specific plan's list.

Private health insurance usually does not cover treatments lacking clear regulatory approval, so the odds of reimbursement through that channel are especially low. In any case, it's advisable to get written confirmation from your fund or insurer before starting treatment, rather than relying on a verbal promise from the clinic performing it.

What to Check Before You Start

Before booking an ozone therapy appointment, it's worth going through the following checklist.

• Whether you have written confirmation from your fund or insurer that this specific treatment is recognized under שב"ן or a complementary-medicine service letter
• Whether the clinic employs a physician with recognized training in ozone therapy, not just a practitioner without a medical background
• Whether safety equipment and immediate response capability are in place for an unexpected reaction
• Whether you've disclosed the planned treatment to your family doctor or primary treating physician, including underlying conditions and regular medications
• Exactly what's included in the cost - number of sessions, follow-up tests, and whether hidden costs exist
• The reimbursement filing process if partial eligibility exists, and which documents are required

Practical Bottom Line

Ozone therapy currently sits in a gray area between complementary and conventional medicine: it's available in Israel through private clinics, but without a defined indication approval from the Ministry of Health and with a limited evidence base. Anyone considering it should go in with eyes open - check funding in writing beforehand, verify the practitioner's safety and skill, and remember it is not a substitute for conventional medical follow-up or treatment of an existing condition.
