Knee pain can disrupt daily life for many older adults. Conditions like osteoarthritis often lead to stiffness, swelling, and limited mobility. When conservative treatments fail, knee replacement surgery becomes a viable option to restore function and reduce discomfort.
Medicare provides coverage for this procedure under certain conditions. Original Medicare includes Parts A and B, which handle hospital stays and medical services. Understanding how these parts apply helps patients plan effectively.
This guide explores eligibility, costs, and additional options. It aims to clarify the process for those considering surgery. Always consult your doctor and Medicare plan for personalized advice.
What Is Knee Replacement Surgery?
Knee replacement involves removing damaged bone and cartilage from the joint. Surgeons then insert artificial components made of metal and plastic. This procedure, also called knee arthroplasty, typically lasts one to two hours under anesthesia.
Patients often experience significant pain relief afterward. Recovery includes physical therapy to regain strength and range of motion. Total knee replacement addresses the entire joint, while partial targets specific areas.
The surgery suits those with severe arthritis or injury. Doctors recommend it when pain interferes with walking or sleeping. Success rates are high, with most implants lasting 15 to 20 years.
Medicare Coverage for Knee Replacement
Original Medicare (Parts A and B)
Part A covers inpatient hospital stays for knee replacement. This includes room costs, nursing care, and meals during admission. Coverage applies if your doctor admits you as an inpatient and deems the surgery medically necessary.
For outpatient procedures, Part B handles surgeon fees and anesthesia. It also covers pre-surgery tests like X-rays or MRIs. Physical therapy sessions after discharge fall under Part B as well.
Both parts require meeting deductibles before coverage begins. Part A has no annual limit on benefit periods. Part B covers 80% of approved amounts after its deductible.
Medicare Advantage (Part C)
Medicare Advantage plans must match Original Medicare coverage for knee replacement. These private plans often include extras like transportation to appointments. Some offer lower out-of-pocket costs for surgeries.
Plans vary by provider and location. Prior authorization may be required before surgery. Check your plan’s network to ensure your hospital and surgeon participate.
Advantage plans cap annual out-of-pocket expenses. This protects against high costs from complications. Review your Evidence of Coverage document for specifics.
Prescription Drug Coverage (Part D)
Part D plans cover pain medications prescribed after surgery. This includes opioids for short-term use or anti-inflammatories. Coverage helps manage post-operative discomfort at home.
Plans have formularies listing covered drugs. Tier levels affect copayments. Generic options often cost less than brand names.
If your Advantage plan includes drug coverage, it functions similarly. Compare plans during open enrollment for better drug benefits. Some medications require step therapy before approval.
Eligibility Requirements for Coverage
Medicare covers knee replacement only if medically necessary. Your doctor must document severe joint damage through imaging. This includes X-rays showing bone-on-bone contact or significant narrowing.
Conservative treatments must have been tried first. These include physical therapy, weight management, or injections. Failure of these options supports the need for surgery.
Pain must limit daily activities like walking or climbing stairs. Resting pain or instability also qualifies. Medicare follows specific criteria for total or partial replacements.
No age limit exists for coverage. Eligibility applies to those 65 and older or with qualifying disabilities. Surgery must occur at a Medicare-approved facility.
Here are key medical necessity criteria:
- Advanced osteoarthritis or rheumatoid arthritis confirmed by imaging.
- Functional limitations despite non-surgical interventions.
- Deformity or instability in the knee joint.
- Avascular necrosis or fractures affecting the knee.
Costs Involved in Knee Replacement with Medicare
Under Original Medicare, expect to pay deductibles and coinsurance. Part A deductible is $1,736 per benefit period in 2026. After that, days 1-60 cost nothing for inpatient stays.
For longer hospital stays, coinsurance applies. Days 61-90 cost $434 each. Lifetime reserve days beyond 90 add $868 per day.
Part B deductible stands at $283 annually. Then, you pay 20% of approved amounts for doctor services and outpatient care. This includes surgeon fees during surgery.
Total out-of-pocket costs vary by procedure type. Inpatient surgeries might total $2,000-$5,000 after coverage. Outpatient often costs less due to lower facility fees.
Additional expenses include physical therapy copays. Each session might cost 20% under Part B. Home health aids could add up if needed.
| Coverage Type | What It Covers | Your Potential Costs (2026) |
|---|---|---|
| Part A (Inpatient) | Hospital room, nursing, meals | $1,736 deductible; $434/day (61-90); $868/day (91+) |
| Part B (Outpatient/Medical) | Surgeon, anesthesia, therapy | $283 deductible; 20% coinsurance |
| Part C (Advantage) | Similar to A/B plus extras | Varies; often lower copays, annual max out-of-pocket |
This table compares core aspects. Actual amounts depend on your specific plan and procedure details.

Preparing for Your Knee Replacement
Start with a thorough doctor consultation. Discuss your symptoms and medical history. Obtain necessary imaging to confirm eligibility.
Arrange pre-surgery tests like blood work. Quit smoking if applicable to improve healing. Strengthen muscles through prescribed exercises.
Plan for transportation home post-surgery. Stock up on easy meals and aids like ice packs. Inform family about your recovery needs.
Review your Medicare coverage details. Confirm hospital acceptance of Medicare assignment. Ask about any required referrals.
Mental preparation matters too. Learn about the procedure to reduce anxiety. Join support groups for shared experiences.
Post-Surgery Care and Rehabilitation
Recovery begins immediately after surgery. Hospital staff monitors for complications like infection. Pain management uses medications and ice.
Physical therapy starts within days. Sessions focus on walking and bending the knee. Home exercises reinforce progress.
Medicare covers up to 100 days in a skilled nursing facility if needed. This requires a qualifying hospital stay first. Part A handles costs after day 20 with coinsurance.
Outpatient therapy under Part B has no session limit if medically necessary. You pay 20% after deductible. Track progress with your therapist.
Watch for signs of issues like swelling or fever. Follow-up appointments ensure proper healing. Full recovery takes 3-6 months for most.
Here are tips for smooth rehabilitation:
- Use assistive devices like walkers initially.
- Elevate your leg to reduce swelling.
- Adhere to weight-bearing instructions.
- Incorporate low-impact activities gradually.
Alternatives to Knee Replacement
Non-surgical options include pain relievers like NSAIDs. These reduce inflammation without invasive procedures. Topical creams offer localized relief.
Injections provide temporary help. Corticosteroids ease swelling, while hyaluronic acid lubricates the joint. Effects last several months.
Physical therapy strengthens surrounding muscles. It improves stability and reduces pain. Braces support the knee during activities.
Weight loss lessens joint stress. Even modest reductions help. Low-impact exercises like swimming maintain mobility.
Stem cell or PRP therapy shows promise. These regenerative approaches aim to repair tissue. Coverage varies, so check with Medicare.
Arthroscopic surgery cleans the joint minimally. It’s less invasive than full replacement. Discuss suitability with your orthopedist.
Conclusion
Knee replacement can transform lives by restoring mobility and easing pain. Medicare offers solid coverage when criteria are met, but planning for costs is key. Explore supplements or Advantage plans for extra protection. Stay informed to make the best choices for your health.
