Changed insurance? Here's what to do with leftover diabetic supplies

Insurance changes — whether from a new job, an open enrollment switch, or a Medicare formulary update — are a frequent reason people contact buyback companies. Your new plan covers FreeStyle Libre 3 but you have a cabinet full of sealed G7 sensors. Or your new employer plan requires OmniPod but you just stocked up on DASH pods. Here's exactly what to do.

Why this happens so often

Health insurance formularies — the list of covered drugs and devices — change every year. A CGM that was previously preferred may become non-preferred after a formulary change, making the monthly cost jump from $35 to $200+. Most people make the rational decision to switch brands, which leaves sealed boxes of the old system behind.

The timing compounds the problem. If you ordered a 90-day supply in November and your new insurance started January 1, you might have two months of the old brand sitting unopened when you can no longer use it.

The most common switch scenarios

• Dexcom G6 → G7 (or vice versa) — not interchangeable; sensors and apps are specific to each system
• FreeStyle Libre 2 → Libre 3 — different readers; sensors from one don't work with the other's app
• OmniPod DASH → OmniPod 5 — different controllers; pods are not interchangeable
• Any CGM → different brand — Dexcom to Libre, Libre to Dexcom, etc.
• Test strip brand changes — formulary requires Contour Next instead of OneTouch, or Accu-Chek instead of FreeStyle Lite

Can you sell supplies purchased through insurance?

Insurance payment does not create a universal resale rule. Eligibility can depend on the product, package labeling, payer or supplier terms, government-program involvement, ownership, and state law.

Do not offer items labeled for Medicare, Medicaid, samples, institutional use, or “not for resale.” If coverage came through a government program or the plan’s terms are unclear, contact the plan or dispensing supplier before transferring the supplies.

Act before the expiration window closes

The most time-sensitive piece of this: expiration dates keep running. Supplies with 12 months remaining are worth significantly more than supplies with 4 months remaining. And once you drop below 3 months, most buyers can't accept them at all.

If your insurance changed in January and your leftover G6 sensors expire in September, you have a limited window to act at full value. Don't let the deadline creep up.

How the process works

1. Check boxes for Medicare/Medicaid labeling — those can't be sold
2. Note expiration dates on each item type
3. Submit a quote request with brand, quantity, and expiration dates
4. Receive a same-day offer from us
5. Accept and receive your free prepaid UPS label
6. Pack and ship — paid same day we receive

Frequently asked questions

What happens to my supplies when I change insurance?

If your new plan requires a different CGM brand or test strip brand, your sealed supplies from the old plan become sellable personal property. You can sell them legally as long as they're sealed, unexpired, and not Medicare/Medicaid-labeled.

Can I sell supplies I got through my old insurance?

Yes — supplies covered by private insurance are your personal property once received. The key restriction is Medicare and Medicaid labeling, which prohibits resale regardless of when they were obtained.

How fast can I get paid after an insurance change?

Once you submit a quote and accept an offer, we send you a free prepaid UPS label by text or email the same day. Most packages arrive within 2–4 business days. You're paid the same day we receive and inspect your supplies.

What if my new insurance doesn't cover the same CGM?

This is one of the most common reasons people sell with us. If your new plan requires Dexcom instead of FreeStyle Libre (or vice versa), your sealed previous-plan sensors can be sold for cash through our mail-in program.
