The good news: replacement is well covered
Hip and knee replacement for arthritis is a standard covered benefit under Medicare and essentially all commercial insurance when medically indicated — meaning documented arthritis plus symptoms that persist despite conservative care. Coverage applies whether surgery happens in a hospital or an approved ambulatory surgery center, and regardless of surgical approach or robotic assistance.
What determines your out-of-pocket cost
Your own costs depend on your plan's structure rather than the surgery itself: your deductible and how much of it you've met this year, your coinsurance or copay tiers, your out-of-pocket maximum, and whether your surgeon, facility, and anesthesia group are in network. Patients who have met their deductible late in a calendar year sometimes time surgery to take advantage of it.
Outpatient surgery-center settings can carry lower facility fees than hospital stays for the same procedure — one more reason candidacy for same-day surgery is worth discussing.
Questions to ask before scheduling
Ask your insurer: Is prior authorization required? Are the surgeon, facility, and anesthesia providers in network? What's my remaining deductible and out-of-pocket max? Is physical therapy covered, and for how many visits? The practice's team helps navigate authorization — bring your insurance card to your consultation and the staff can verify benefits.
