Met Your Deductible? Why December Is the Smartest Time for Hip or Knee Replacement

Already hit your 2026 deductible? Learn why Metro Detroit patients schedule hip and knee replacement before Jan 1 — and how Dr. Ali Sobh can help you plan before year-end surgery dates fill.

If you have spent this year living with a painful hip or knee, there is a good chance you have also spent this year paying toward your health insurance deductible. Imaging, injections, physical therapy, specialist visits — it adds up. And on January 1, most plans reset that progress to zero. That is why late fall is the busiest season for joint replacement across the country. For many patients, the math is simple: if you have already met your deductible or out-of-pocket maximum, having surgery before the year ends can significantly lower what you pay for the same procedure.

How your deductible affects the cost of joint replacement

Your deductible is the amount you pay out of pocket before your insurance starts covering care. After you meet it, most plans move to coinsurance — you pay a percentage, and insurance pays the rest — until you reach your out-of-pocket maximum. After that, covered care is typically paid in full for the remainder of the plan year.

Most plans run on the calendar year. That means:

• If you have met your deductible: your share of a hip or knee replacement this year may be limited to coinsurance.
• If you have hit your out-of-pocket maximum: covered costs for the rest of the year may be paid entirely by your plan.
• If you wait until January: you start over, and your deductible applies first.

Every plan is different. Before scheduling, call your insurer and ask three questions: How much of my deductible have I met? How close am I to my out-of-pocket maximum? Does my plan require prior authorization for joint replacement? Our team can help you through the authorization process once you have those answers.

Who benefits most from scheduling before January 1

Year-end scheduling makes the most sense if you:

• Have already been told you are a candidate for hip or knee replacement and have been putting it off
• Have had imaging, injections or therapy this year that counted toward your deductible
• Have a high-deductible health plan (HDHP)
• Have unused FSA dollars that may expire at year-end — confirm eligible uses with your plan administrator
• Have pain in both knees or both hips and want to plan the first joint now

Why winter is a good season to recover

The financial reason is the headline, but many patients find winter is simply a practical time to recover. The holidays often bring time off work and family close by to help. Michigan's coldest months are when most people are indoors anyway. And by the time spring arrives, you can be walking, golfing, gardening and traveling on a joint that no longer hurts.

Modern techniques make that timeline more realistic than ever. With direct anterior hip replacement, Dr. Sobh reaches the hip joint between muscles rather than cutting through them, which is designed to support a faster, more comfortable early recovery. With MAKO robotic-arm assisted knee replacement, each implant is planned from a 3D model of your own knee and placed with robotic precision.

Don't wait on joint pain just to save money later

Saving money is a good reason to schedule now. It is not a good reason to keep putting surgery off year after year. Joints with advanced arthritis can continue to lose motion and strength, and the muscles around them weaken as you move less. Patients who wait too long often face a harder recovery. If your pain is limiting your sleep, your walking or your work, it is worth an evaluation now — regardless of the calendar.

How to plan for surgery before the year ends

Year-end surgery requires a few steps, so starting early matters:

• 1. Schedule a consultation. Dr. Sobh will examine your joint, review your imaging and confirm whether replacement is the right next step.
• 2. Complete pre-surgical clearance. This usually includes lab work and a visit with your primary care physician.
• 3. Prior authorization. Many insurers require approval before surgery, and some require proof that conservative treatment was tried first. Our office handles the paperwork.
• 4. Lock in your surgery date. December dates fill quickly at hospitals and surgery centers across Metro Detroit.

Frequently asked questions

If I've met my deductible, is my surgery free?

Not always. Many plans still require coinsurance after the deductible until you reach your out-of-pocket maximum. Call your insurer to confirm your exact numbers.

Is it too late to schedule joint replacement this year?

It depends on clearance and authorization timelines. The sooner you schedule a consultation, the better your chances. Call (833) 667-3627 to check current availability.

Can I have both knees or both hips replaced in the same year?

Some patients do, typically a few months apart, but not everyone is a candidate. Dr. Sobh will determine the safest timeline for you based on your anatomy and recovery.
