Frequently asked questions

A continuous glucose monitor, or CGM, is a small sensor you wear that measures your glucose throughout the day and night. Instead of a single number from a fingerstick, you see how your glucose is moving over time.

A small sensor worn on the back of your upper arm measures glucose in the fluid just under your skin and sends readings wirelessly to a compatible smartphone or reader— updated every minute, automatically.

People living with Type 1 or Type 2 diabetes who want a closer look at their glucose. Seeing patterns can help you and your provider understand how food, activity, and medication affect your levels. Your healthcare provider can help decide whether it's right for you.

In most cases a prescription or supporting documentation from your provider is needed, especially when a brace is billed to insurance. Requirements vary, and our team can walk you through what's needed for your situation.

We don't recommend a specific brace on our own. The right support depends on your diagnosis and your body. Your physician will confirm the brace style when prescribing it.

We supply back, knee, ankle, and wrist supports. You can see an overview on our orthotic braces page.

Sizing is based on measurements and your provider's guidance. Reach out to our team and we'll help you confirm the right size before your order goes out. Many braces are also universal in size.

Generally no. Resupply follows the duration your physician prescribed, and we reach out when your next shipment is due so nothing slips through the cracks.

Orders typically arrive within a few business days once they've been processed, though timing can vary by product and location.

Please contact our support team. We'll track the order down and help sort out a replacement or reshipment if it's needed.

Just let our support team know and we'll update your file before your next shipment goes out.

We work with Medicare and other major payors such as Humana, Aetna, United Healthcare, and many others. Coverage depends on your specific plan and prescription, so please contact us and we'll help review your eligibility.

We can't promise coverage in advance — it depends on your plan, your documentation, and your provider's prescription. We'll tell you what information is needed and keep you posted on what we hear back.

Where your plan applies, we bill your insurance first. Anything left over, such as a deductible or copay, is billed to you afterward.

A sensor that comes off needs to be replaced — it can't be reapplied. Clean and dry a new site before applying the replacement, and contact our team so we can help.

A new sensor can take up to an hour to warm up before it gives readings. If it still isn't working after that, check that it's placed correctly on the back of your upper arm and reach out to us.

Keep the site clean and dry before applying, consider an adhesive patch or sensor cover, and try to avoid excess moisture and knocks or bumps.

Check that Bluetooth is turned on and your phone is nearby, then try restarting the app or your phone. Reinstalling the app can also help if the problem sticks around.

Make sure the site is clean, dry, and free of lotions or oils before you apply the sensor. An extra adhesive patch can help during vigorous activity.

Try a clean, dry site and consider a barrier wipe or a different adhesive. If irritation continues, please check in with your healthcare provider.

A brief moment of discomfort is common, but ongoing pain is not. Remove the sensor and speak with your healthcare provider, then contact us about a replacement.
