Learn About Medicare Coverage for Knee Treatment
How Medicare Covers Knee Treatment
Medicare is a federal health insurance program that covers certain medical services and treatments for people age 65 and older, as well as some younger people with disabilities or end-stage renal disease. When it comes to knee treatment, Medicare covers various procedures and services, but the amount of coverage depends on which part of Medicare you have and the specific type of treatment you need.

Medicare Part A covers hospital inpatient services, which means if you need knee surgery that requires an overnight hospital stay, this part may cover the hospital facility costs. Medicare Part B covers outpatient services, including doctor visits, diagnostic tests, and outpatient surgical procedures. For knee treatment, this might include imaging like X-rays or MRI scans ordered by your doctor, office visits with orthopedic specialists, and certain outpatient procedures.
It's important to understand that Medicare coverage for knee treatment typically requires that the treatment be medically necessary—meaning a doctor has determined it's needed to treat a specific knee condition or injury. The treatment must also be performed by a Medicare-enrolled provider or facility. Medicare does not cover treatments considered experimental, cosmetic, or not medically necessary.
The coverage structure means you may be responsible for certain costs even when Medicare covers the service. These might include deductibles (the amount you pay before Medicare starts paying), coinsurance (a percentage of the cost you share with Medicare), and copayments (fixed amounts you pay per visit). Understanding these out-of-pocket costs helps you plan financially for knee treatment.
Practical Takeaway: Before pursuing any knee treatment, ask your healthcare provider whether they accept Medicare and what specific services they plan to provide. Request information about which Medicare parts cover each service and what costs you might owe.
Types of Knee Conditions Medicare May Cover
Medicare covers treatment for various knee conditions that affect people as they age or due to injury. Osteoarthritis is one of the most common conditions Medicare covers. This is the wear-and-tear arthritis that develops when the protective cartilage in the knee joint gradually breaks down. Many people over 65 experience some degree of osteoarthritis, and Medicare covers diagnostic imaging, office visits with doctors, physical therapy, and surgical interventions like knee replacement when the condition becomes severe enough.

Meniscus tears are another condition Medicare covers. The meniscus is cartilage in the knee that acts as a shock absorber. Tears can happen from sports injuries or degenerative changes over time. Medicare covers the diagnostic imaging needed to confirm a meniscus tear, such as MRI scans, and may cover arthroscopic surgery (minimally invasive surgery using a camera) to repair or remove damaged meniscus tissue.
Knee injuries from accidents or falls are also covered, including anterior cruciate ligament (ACL) tears, posterior cruciate ligament (PCL) injuries, and ligament sprains. Medicare covers the emergency room visits, imaging studies, and surgical reconstruction if needed. Bursitis (inflammation of small fluid-filled sacs around the knee) and tendinitis (inflammation of tendons) are conditions where Medicare covers office visits, imaging, injections, and physical therapy.
Rheumatoid arthritis affecting the knee is another condition with Medicare coverage. Unlike osteoarthritis, rheumatoid arthritis is an autoimmune condition. Medicare covers the rheumatology office visits, laboratory tests to monitor the condition, imaging studies, and various treatment options including medications and physical therapy. In some cases, if the rheumatoid arthritis causes significant knee damage, surgical options may also be covered.
Practical Takeaway: Keep a record of your knee symptoms and when they started. This information helps your doctor determine what condition you have and whether treatment is medically necessary for Medicare coverage purposes.
Diagnostic Services and Imaging Coverage
When you have knee pain or injury, the first step is usually getting a diagnosis. Medicare Part B covers the office visit with your doctor or specialist to evaluate your knee problem. This initial consultation allows your healthcare provider to take a history, perform a physical examination, and determine what diagnostic tests might be needed.

X-rays are among the most common diagnostic tools for knee problems and are covered by Medicare. X-rays can show bone fractures, joint alignment, and signs of arthritis. A standard knee X-ray typically costs between $100 and $300 for the facility fee, though your out-of-pocket cost depends on your deductible and coinsurance. Medicare covers 80% of the cost after you meet your Part B deductible (which is $240 in 2024).
MRI (magnetic resonance imaging) scans are more detailed and can show soft tissue damage like meniscus tears, ligament injuries, and cartilage problems. Medicare covers MRI scans when ordered by your physician for a medically necessary reason. The facility fee for a knee MRI ranges from $400 to $3,500 depending on where you get it done, though Medicare negotiates specific payment rates. You typically pay 20% of the Medicare-approved amount after meeting your deductible.
CT (computed tomography) scans may be ordered in certain situations to get a three-dimensional view of knee structures. Medicare covers these when medically necessary. Ultrasound imaging of the knee can visualize soft tissues and fluid and is also covered. Some newer imaging techniques, like advanced 3D imaging, may have coverage limits, so it's worth asking your provider what imaging they're recommending and confirming Medicare covers it.
Physical examination by your doctor may include special tests like the Lachman test (for ACL injuries) or McMurray's test (for meniscus tears). These office-based assessments are covered as part of your doctor visit. If your doctor thinks you might need surgery, they may order imaging to confirm the diagnosis before proceeding.
Practical Takeaway: Ask your doctor which imaging tests they're recommending and why. Request that they use Medicare-enrolled facilities for imaging, as this ensures you receive the Medicare negotiated rates and proper coverage.
Physical Therapy and Conservative Treatment Options
Medicare Part B covers physical therapy as an outpatient service when it's ordered by your physician for a knee condition. Physical therapy is often the first treatment approach for many knee problems and can be effective for conditions like osteoarthritis, ligament sprains, post-surgical rehabilitation, and tendinitis. The coverage includes the cost of the physical therapist's services and any equipment used during therapy sessions.

In 2024, Medicare covers up to 30 visits per benefit period (with some exceptions) for physical therapy related to orthopedic conditions like knee problems. Each visit typically costs between $50 and $150 for your coinsurance, depending on your plan and whether you've met your deductible. Your physical therapist should be Medicare-enrolled, and the therapy must be medically necessary and aimed at improving your knee function.
During physical therapy for knee problems, patients typically work on exercises to strengthen the muscles around the knee (particularly the quadriceps and hamstrings), improve flexibility, restore range of motion, and reduce pain. A physical therapist might use techniques like manual therapy, heat or cold therapy, electrical stimulation, or ultrasound as part of your treatment plan. Each session usually lasts 30 to 60 minutes.
Medicare also covers certain injections for knee conditions as a conservative treatment option. Corticosteroid injections can reduce inflammation in the knee joint and provide pain relief, particularly for arthritis. Hyaluronic acid (viscosupplementation) injections may be covered in some cases for knee osteoarthritis. These injections are typically given in your doctor's office and cost you coinsurance based on the office visit fee, usually between $20 and $50 per injection.
Medications prescribed by your doctor for knee conditions may also have coverage through Medicare Part D (prescription drug coverage), if you're enrolled in a Part D plan. Common medications for knee arthritis and pain include NSAIDs (nonsteroidal anti-inflammatory drugs), acetaminophen, and in some cases, topical creams or ointments.
Practical Takeaway: Before starting physical therapy, confirm with the facility that they accept Medicare and understand your out-of-pocket costs per visit. Ask your doctor about the expected number of visits and what improvements you should expect.
