Got Questions? We Have Answers.

What do I need to do to get started?

The process begins by clicking Get Sparrow Ascent to see if you qualify. If you do, you’ll be connected via telehealth with a U.S. licensed substance use provider to discuss your specific needs and determine whether Sparrow Ascent is the right next step on your recovery journey.

Your telehealth provider will never prescribe a treatment without first addressing any questions or concerns. He or she will also be available for continued substance use treatment support. If you're deemed a good candidate for Sparrow Ascent, then the telehealth provider will prescribe treatment and it will be shipped directly to your home.

Does my insurance cover Sparrow Ascent?

Although Sparrow Ascent is FDA-cleared, it is not yet covered by insurance. That means you’ll need to pay out of pocket for the device. You can also use HSA or FSA dollars to cover the cost of Sparrow Ascent. The cost of your office visit or telehealth appointment may be covered by US-based health insurance carriers.

What happens after I complete the treatment?

Sparrow Ascent is designed to make overcoming opioid withdrawal easier. But overcoming withdrawal is just the first step on your recovery journey. What happens next is even more important and up to you. Your telehealth provider may prescribe additional out-patient counseling or other programs to ensure you address the circumstances that led to opioid use in the first place.

Should you need more than 28 earpieces, additional earpiece packs may be prescribed as needed at an additional cost.

How much does Sparrow Ascent cost?

The List Price of the Sparrow Ascent Kit is $4,500, but with the instant $1,000 patient rebate, you will only pay $3,500. This is significantly lower than traditional in-patient behavioral health programs, which average about $20,000 per detox.

Although Sparrow Ascent is FDA-cleared, it is not yet covered by insurance. That means you’ll need to pay out of pocket for the device, though you may be able to use HSA or FSA dollars to cover the cost of Sparrow Ascent. Rebates and Costs of Sparrow Ascent from Healthcare Providers may vary.

The Sparrow Ascent shipment comes with a total of 28 daily-disposable earpieces. However, your healthcare provider may prescribe additional Sparrow Ascent Earpieces for purchase if needed. A 7-pack of Earpieces costs $600.
