Medicare Coverage for Axonics Therapy

Medicare does cover Axonics therapy, but only under specific conditions. Axonics is a sacral neuromodulation device — a small implant that sends electrical pulses to nerves that control bladder and bowel function. Medicare Part B covers the device and the surgical implantation procedure, but you must meet clinical criteria and follow Medicare's approval process before the procedure can happen.

The key requirement is that you must have already tried and failed conservative treatments. This means you need documentation showing that you have used behavioral therapy, pelvic floor exercises, or medications for at least six weeks without adequate improvement. Medicare also requires that your condition — overactive bladder, urinary retention, or fecal incontinence — be diagnosed by a urologist or colorectal specialist, not a primary care doctor.

Coverage also depends on which Medicare plan you have. Original Medicare (Parts A and B) covers the procedure at an in-network hospital or surgical center. If you have a Medicare Advantage plan, coverage varies by plan, and some plans may require prior authorization or have different cost-sharing rules.

Key Takeaways

  • Medicare Part B covers both the Axonics device and the surgical implantation procedure, but only after you have documented six weeks of failed conservative treatment.
  • A urologist or colorectal specialist must diagnose your condition and recommend the device — your primary care doctor's referral alone is not enough.
  • Your doctor's office must submit a prior authorization request to Medicare before scheduling surgery, and this process typically takes one to two weeks.
  • You will owe the Part B deductible (currently $226 per year) and 20 percent coinsurance for the procedure, unless you have supplemental coverage.
  • Medicare Advantage plans may have different rules, so contact your plan directly to confirm coverage before moving forward.

What Conservative Treatment Documentation You Need

Medicare requires proof that you have tried and failed at least one conservative treatment before approving Axonics. Conservative treatments include pelvic floor physical therapy, behavioral modifications (like timed voiding or dietary changes), and medications such as anticholinergics for overactive bladder or alpha-blockers for urinary retention.

Your urologist or specialist must document in your medical record the specific treatments you tried, the dates you used them, and why they did not work for you. "Did not work" means the symptoms did not improve enough to be functional — not that you disliked the treatment or found it inconvenient. Medicare reviewers will look for notes showing that you gave each treatment a fair trial, usually at least six weeks.

If your doctor has not documented this clearly, ask them to add a note to your chart before submitting the prior authorization. Vague documentation is the most common reason Medicare denies Axonics requests on the first submission.

The Prior Authorization Process and Timeline

Before your surgery can be scheduled, your urologist's or colorectal specialist's office must submit a prior authorization request to Medicare. This request includes your medical history, the conservative treatments you have tried, imaging or test results showing your condition, and the surgeon's recommendation for Axonics.

Medicare typically responds to prior authorization requests within 5 to 14 business days. If approved, you will receive a letter confirming coverage, and your surgeon's office can then schedule the implantation procedure. If denied, the letter will explain the reason — usually missing documentation or insufficient trial of conservative treatment — and you have the right to appeal.

Do not schedule surgery before receiving the approval letter. If you do and Medicare later denies the request, you may be responsible for the full cost of the procedure and device, which can exceed $30,000.

Your Out-of-Pocket Costs Under Original Medicare

Under Original Medicare, you pay the Part B deductible ($226 in 2024, though this amount changes yearly) and then 20 percent coinsurance for the procedure and device. The total cost of Axonics implantation, including the device, surgeon fees, and facility charges, typically ranges from $25,000 to $35,000 before insurance, so your 20 percent coinsurance could be $5,000 to $7,000.

If you have a Medigap supplemental policy, it may cover some or all of your coinsurance, depending on which Medigap plan you hold. Plans C, D, G, and M typically cover the Part B coinsurance. If you have a Medigap policy, contact your supplemental insurer before surgery to confirm what they will pay.

If you cannot afford the coinsurance, ask your surgeon's billing department about payment plans. Many hospitals offer interest-free financing for patients who owe more than a certain amount.

Medicare Advantage Plan Coverage

Medicare Advantage plans are required to cover Axonics at least as generously as Original Medicare does, but they can impose additional requirements. Some plans require prior authorization, some charge a higher copay or coinsurance than Original Medicare, and some may limit which surgeons or facilities you can use.

Contact your Medicare Advantage plan's member services line before your doctor submits the prior authorization request. Ask whether the plan covers Axonics, what documentation they need, whether your surgeon is in-network, and what your out-of-pocket cost will be. Having this information in advance prevents delays and surprises.

If your plan denies coverage and you believe the denial is wrong, you have the right to appeal. Your surgeon's office can help you file an appeal and provide medical evidence supporting the need for the procedure.

What Happens If Medicare Denies Your Request

If Medicare denies your prior authorization request, the denial letter will state the specific reason. The most common reasons are: insufficient trial of conservative treatment, missing documentation from your specialist, or a diagnosis that does not meet Medicare's criteria for Axonics.

You have 120 days from the denial date to file an appeal. The appeal process has multiple levels: reconsideration (reviewed by a different Medicare contractor), followed by an administrative law judge hearing if you are still denied. Many patients succeed on appeal after their doctor provides additional documentation or clarification.

Your surgeon's office can guide you through the appeal process. Some offices have staff dedicated to insurance appeals and can resubmit with stronger documentation without you having to do the work yourself.

Frequently Asked Questions

Do I need to try medications before Axonics, or is physical therapy enough?

Medicare requires documentation of at least one conservative treatment, which can be physical therapy, medication, or behavioral changes. You do not need to try all three — one documented six-week trial that did not work is sufficient. If you have already tried medication and it failed, physical therapy documentation alone may be enough, depending on your condition.

Can my primary care doctor refer me for Axonics, or does it have to be a specialist?

Medicare requires that a urologist or colorectal specialist diagnose your condition and recommend Axonics. Your primary care doctor can refer you to a specialist, but the specialist must be the one who submits the prior authorization request to Medicare. A prior authorization submitted by a primary care doctor will likely be denied.

What if I have both Original Medicare and a Medicare Advantage plan?

You cannot have both at the same time. If you are enrolled in a Medicare Advantage plan, that is your primary coverage, and Original Medicare is secondary. Contact your Medicare Advantage plan for coverage information. If you want to switch to Original Medicare, you can do so during the annual enrollment period (October 15 to December 7) or if you have a may have access to life event.

How long after approval can I have the surgery?

Once Medicare approves your prior authorization, your surgeon's office can schedule the procedure as soon as an operating room slot is available. This typically happens within two to four weeks, but it depends on your surgeon's schedule and the facility's availability. Ask your surgeon's office for an estimated date when you receive the approval letter.

Will Medicare cover the trial period before permanent implantation?

Yes. Axonics therapy usually begins with a trial period, during which a temporary external device is worn for three to five days to test whether the therapy works for you. If the trial is successful, you then proceed to permanent implantation. Medicare covers both the trial and the permanent implant under the same prior authorization.
