Medicare covers Axonics therapy, but only under specific conditions

Axonics is a neuromodulation system — a small implanted device that sends mild electrical pulses to nerves to treat overactive bladder and bowel control problems. Medicare Part B covers the device and the surgical implant procedure, but you will need to meet certain medical requirements first. Your doctor must document that you have tried conservative treatments (like pelvic floor exercises or medications) without adequate relief before Medicare will pay for the implant.

Coverage also depends on which Axonics system your doctor recommends. Medicare covers the rechargeable Axonics r-SNM system for overactive bladder symptoms. The specific approval process and any out-of-pocket costs you face depend on whether your doctor's office is in-network with Medicare and whether you have supplemental coverage.

Key Takeaways

  • Medicare Part B covers the Axonics implant procedure and device for overactive bladder when conservative treatments have not worked.
  • Your doctor must document a trial of at least one other treatment method before requesting Medicare authorization for the implant.
  • You will typically pay 20 percent of the approved amount for the procedure after you meet your Part B deductible.
  • The surgical center or hospital where the implant is placed must be Medicare-enrolled for the procedure to be covered.
  • Prior authorization from Medicare is required before the procedure — your doctor's office handles this step.

What Medicare requires before covering the implant

Medicare does not cover Axonics as a first-line treatment. You must have already tried and documented failure with at least one other approach. This usually means your doctor has prescribed oral medications for overactive bladder (such as anticholinergics) or you have completed a course of pelvic floor physical therapy without reaching your symptom goals.

Your urologist or urogynecologist will need to document this trial in your medical record with specific dates and details about why the treatment did not work for you. Medicare reviewers look for evidence that the conservative treatment was given a fair trial — typically at least 4 to 12 weeks depending on the medication or therapy type.

You will also need a diagnosis code that Medicare recognizes. Overactive bladder (OAB) is the most common diagnosis covered. Some patients with neurogenic detrusor overactivity (a bladder control problem related to spinal cord injury or multiple sclerosis) may also meet criteria, but this requires additional documentation from your neurologist or specialist.

How the prior authorization process works

Before your surgery date is scheduled, your doctor's office submits a prior authorization request to Medicare. This request includes your medical records, the documentation of failed conservative treatments, and the specific Axonics model your surgeon plans to implant. Medicare typically responds within 5 to 10 business days, though the timeline can vary.

If Medicare denies the request, your doctor can appeal. The appeal process allows your doctor to submit additional clinical information or clarification about why you meet the coverage criteria. Many initial denials are overturned on appeal, especially if the documentation of prior treatment was incomplete in the first submission.

You should not schedule your implant surgery until you have written approval from Medicare. If you proceed without authorization, you may be responsible for the full cost of the procedure, which typically ranges from $15,000 to $25,000 depending on the facility and surgeon.

What you pay out of pocket

Once Medicare approves the procedure, your out-of-pocket cost depends on your deductible status and whether you have supplemental insurance. For 2024, the Medicare Part B deductible is $240 per year. After you meet this deductible, Medicare pays 80 percent of the approved amount for the implant procedure, and you pay 20 percent.

The approved amount varies by geographic region and facility type. A hospital outpatient department typically has a higher approved amount than an ambulatory surgery center, which means your 20 percent coinsurance will be higher at a hospital. Ask your surgeon's office for an estimate of the approved amount before your procedure so you know what to expect.

If you have a Medigap supplemental policy, it may cover some or all of your 20 percent coinsurance. If you have a Medicare Advantage plan (Part C), your out-of-pocket costs follow your plan's rules, which may include copays or coinsurance amounts different from Original Medicare. Check your plan documents or call your plan's member services line to confirm your coverage before the procedure.

Differences between Axonics models and coverage

Axonics makes two main systems: the rechargeable r-SNM system and the non-rechargeable system. Medicare covers the rechargeable r-SNM system for overactive bladder. The rechargeable device lasts longer (typically 15+ years) and does not require replacement surgery, which is why Medicare considers it cost-effective over time.

The non-rechargeable Axonics system is also available but has different battery life and replacement requirements. Coverage for non-rechargeable systems may vary, so confirm with your doctor and Medicare before proceeding. Your surgeon will discuss which system is appropriate for your situation based on your age, activity level, and medical history.

What happens if Medicare denies coverage

If Medicare denies your prior authorization request, you have the right to appeal. The appeal process has multiple levels: reconsideration, hearing before an administrative law judge, and further appeal if needed. Many patients succeed on appeal by providing more detailed documentation of their failed conservative treatments or by having their doctor submit additional clinical reasoning.

While your appeal is pending, you can continue to explore other treatment options. Some patients pursue sacral neuromodulation through other manufacturers (such as InterStim) if Axonics is not covered, though coverage criteria are similar across devices. Your doctor can discuss whether an alternative device might be a better fit for your situation.

If you exhaust the Medicare appeal process and coverage is still denied, you may choose to pay out of pocket for the procedure. Some surgeons offer payment plans or discounts for self-pay patients. Before making this decision, discuss the financial impact with your family and consider getting a second opinion from another urologist about whether the procedure is medically necessary for your situation.

Frequently Asked Questions

Do I need to try medications before I can get Axonics?

Yes. Medicare requires documentation that you have tried at least one conservative treatment — usually oral medication or pelvic floor physical therapy — for at least several weeks without adequate symptom relief. Your doctor must include this documentation in the prior authorization request.

How long does it take to get Medicare approval?

Medicare typically responds to prior authorization requests within 5 to 10 business days. If approved, you can schedule surgery. If denied, the appeal process can take several weeks to months depending on the level of appeal and how quickly your doctor submits additional information.

Will I have to pay anything if Medicare covers the procedure?

Yes. You will pay your Part B deductible (if you have not met it for the year) plus 20 percent coinsurance on the approved amount. A Medigap supplemental policy may cover some or all of this coinsurance. Medicare Advantage plans have their own cost-sharing rules.

What if my doctor's office is out of network with Medicare?

If your surgeon is not enrolled with Medicare, you may still receive coverage, but the approved amount may be lower and your coinsurance will be based on that lower amount. Ask your surgeon's office whether they are Medicare-enrolled before scheduling your procedure.

Can I get Axonics covered if I have a Medicare Advantage plan?

Yes, but coverage rules vary by plan. Some Medicare Advantage plans cover Axonics with the same prior authorization requirements as Original Medicare; others may have additional restrictions. Contact your plan's member services line to confirm coverage before your doctor submits a prior authorization request.
