Is Knee Decompression Therapy Covered by Insurance in Charleston?
May 4, 2026
If you have been struggling with knee pain and someone told you that Knee Decompression Therapy might help, your first question was probably not about how it works — it was about whether your insurance will cover it. That is a completely reasonable place to start, and the answer is more nuanced than a simple yes or no. Understanding how insurers classify this treatment, what factors affect eligibility, and what your real financial options look like will help you make a confident decision before stepping into any clinic.
What Is Knee Decompression Therapy and Why Does It Matter?
Knee Decompression Therapy is a non-surgical treatment designed to relieve pressure inside the knee joint by gently stretching and separating the joint surfaces. This process creates negative pressure within the joint, which can draw in synovial fluid, improve circulation, reduce inflammation, and encourage the repair of damaged cartilage and surrounding tissue. In Charleston, SC, this treatment has become a meaningful alternative to cortisone injections or knee replacement surgery, particularly for patients dealing with osteoarthritis, meniscus damage, or degenerative joint disease.
The Knee on Trac® system is one of the most widely used devices for this purpose. It delivers controlled, measurable decompression in a supervised clinical setting. Most patients undergo a series of sessions over several weeks and report meaningful reductions in pain and improvements in mobility — without the risks that come with surgery. Because it sits between conservative physical therapy and invasive surgery, it occupies a complicated position when it comes to how insurers categorize it.
How Insurance Companies Typically Classify This Treatment
Most major health insurers — including Blue Cross Blue Shield, Aetna, Cigna, and Medicare — evaluate treatments based on whether they meet the definition of medically necessary and whether sufficient peer-reviewed clinical evidence exists to support coverage. Knee Decompression Therapy, while clinically supported by many practitioners, is still classified by most insurers as experimental or investigational. This means standard health insurance plans often do not cover it as a standalone treatment.
That said, individual plan details vary widely. Some patients in Charleston, SC have received partial reimbursement by submitting claims with the appropriate ICD-10 diagnostic codes and supporting documentation from their provider. Context matters too: when Knee Decompression Therapy is administered alongside covered services such as chiropractic care or physical therapy, there may be opportunities to structure billing in a way that maximizes your existing benefits.
What to Do Before Your First Appointment in Charleston, SC
Taking a proactive approach before beginning treatment can save you significant expense and frustration. Work through the following steps before committing to a treatment plan.
- Call your insurer directly and ask whether Knee Decompression Therapy or joint distraction therapy is covered under your specific plan.
- Request a letter of medical necessity from your doctor or chiropractor documenting your diagnosis, prior treatments attempted, and the clinical rationale for decompression therapy.
- Ask the clinic to submit a pre-authorization request on your behalf before treatment begins, which creates a paper trail and may improve your chances of at least partial coverage.
- Find out whether your plan includes out-of-network benefits, since some clinics operate outside insurance networks but still allow you to submit claims for partial reimbursement.
- Confirm whether your Flexible Spending Account (FSA) or Health Savings Account (HSA) can be used, since these funds typically apply to this type of treatment even when traditional insurance does not.

Frequently Asked Questions
Does Medicare cover Knee Decompression Therapy?
Medicare does not currently cover Knee Decompression Therapy as a standard benefit because it continues to classify the treatment as investigational. Medicare Advantage plans vary by provider and region, so it is worth calling your specific plan directly.
Can I use my HSA or FSA to pay for treatment?
In most cases, yes. Knee Decompression Therapy qualifies as a medical expense under IRS guidelines, making it eligible for payment through a Health Savings Account or Flexible Spending Account. Confirm with your plan administrator to be certain.
Will my insurance cover the diagnostic work needed before treatment?
Diagnostic services such as X-rays or MRIs ordered by a licensed provider are typically covered under standard insurance plans, even when the treatment that follows is not.
What happens if my insurance denies the claim?
You have the right to appeal a denial. Your provider can assist by preparing clinical notes, supporting research, and a letter of medical necessity. Some appeals succeed when backed by a strong clinical case.
Is Knee Decompression Therapy a one-time cost or ongoing?
Most patients complete an initial course of care over several weeks. Some return for periodic maintenance sessions, but many experience lasting relief without ongoing treatment once the initial plan is finished.
