Your Insurance Changed Brands. What to Do With the Old Supplies

This one is never anybody's decision. A plan year turns over, an employer switches carrier, or a formulary quietly moves, and the letter arrives saying the new plan covers a different meter. The supplies you already have do not stop existing. They just stop being useful, overnight, through nothing you did.

Why the old boxes cannot simply be used up

Test strips are not a generic product. Each strip is calibrated to its own meter, so a OneTouch strip does not work in a Contour meter and a FreeStyle strip does not work in an Accu-Chek. There is no adapter and no setting to change. If the plan moved you to a different brand, the remaining boxes of the old one have no use to you at all.

The same applies on the CGM side, where a plan switching between Dexcom and FreeStyle Libre leaves sealed sensors that belong to a system you no longer have.

The pharmacy generally cannot take them back either. Once a prescription item has been dispensed it usually cannot be returned to stock, which is why people end up holding these rather than simply reversing the order.

The question everyone actually asks

Can you sell supplies that insurance paid for? This is the part that gets people wrong, and it is worth being exact about, because the answer depends entirely on which kind of insurance.

Supplies obtained through a government program cannot be resold. That is a firm line and it applies no matter how they came to be sitting in your cupboard.

Supplies that came through private insurance, an employer plan, or that you paid for yourself, are a different situation. So are supplies handed on by a relative who paid for them privately. In those cases the boxes are ordinary property.

The distinction is about the funding route, not about you, and nobody is asked to prove how a box came into their possession. It matters because a great many perfectly sellable boxes get thrown away by people who assumed that anything an insurer touched was off limits.

What to check before you do anything

• The seal. Factory sealed and unopened, in the original box. Once a box has been opened nobody downstream can verify how it was stored, so an opened box cannot be resold at any price.
• The date. Unexpired for strips, without exception — a degraded strip returns an inaccurate reading, which is a safety problem rather than a bargain. Two exceptions exist on the CGM side: expired Omnipod pods and expired Dexcom G7 sensors still have value, at a reduced rate. Expired Dexcom G6 sensors do not.
• The whole cupboard. A brand change usually leaves more than strips behind — lancets, control solution, unopened meters and, on the CGM side, transmitters and receivers. People carefully keep the strips and bin the rest.

Photograph the sealed boxes with the expiry dates and lot numbers visible before they go anywhere, and keep the photographs until you have been paid. Do not open a box to photograph what is inside — opening it destroys the only thing that made it sellable.

Where it goes from here

For a few boxes, the state pages show who is nearest to you and whether meeting someone in person is realistic where you live. Mail-in works from anywhere and the label costs you nothing.

Brand changes do not only happen to individuals. When a plan moves a whole population, pharmacies and supply companies are left holding the discontinued line in quantity. If that is the situation, or you are a reseller with a hundred pieces or more, the bulk page is the right starting point — mixed brands and mixed dates are expected in a lot that size and do not need sorting first.
