Selling a used insulin pump is more complicated than listing most electronics. Insulin pumps are prescription medical devices, which means major online marketplaces restrict or prohibit their sale, and there are legal gray areas to navigate. Your most straightforward option is a manufacturer trade-in program, but other channels exist depending on your situation.
Manufacturer Trade-In Programs
The simplest and most reliable way to get value from an old insulin pump is trading it back to a manufacturer when upgrading. Medtronic runs the most established program. If your Medtronic pump is out of warranty, you can receive a $1,000 trade-in credit when upgrading to a newer system through insurance. The same $1,000 credit applies to out-of-warranty Tandem, Animas, or Roche pumps. Omnipod receivers qualify for a $750 credit. You need to return your old pump within 30 days of placing the upgrade order.
If your pump is still in warranty but belongs to a competitor brand, Medtronic offers a pathway to switch for as little as $499. And if you’re already a Medtronic customer with an in-warranty MiniMed 770G, 670G, or 630G with more than six months left on the warranty, their Zero Pathway Program lets you upgrade to the MiniMed 780G system at no additional cost.
These credits aren’t cash in your pocket. They’re applied to the cost of a new device through your insurance order. But for most people looking to offload an old pump, this is the cleanest route: no legal ambiguity, no buyer to find, and often a better dollar value than you’d get selling privately.
Why Major Marketplaces Won’t Work
If your first instinct was to list your pump on eBay, Facebook Marketplace, or Craigslist, you’ll likely run into problems. These platforms restrict or outright ban the sale of prescription medical devices. Facebook has been actively shutting down groups and flagging posts where diabetes supplies are sold or traded. Even groups that tried to operate as peer support communities have been forced to migrate to other platforms after repeated flagging.
eBay’s policies on medical devices are similarly restrictive. While you may occasionally see listings slip through, they risk being pulled, and both buyer and seller lose any platform protections if a transaction goes sideways. Craigslist has no formal enforcement mechanism, but selling prescription devices there carries its own risks, from scams to potential legal exposure.
The Legal Gray Area
There is no single federal law that explicitly bans an individual from reselling a personal insulin pump. However, insulin pumps are FDA-regulated prescription devices, meaning they were prescribed specifically for you. The FDA has issued warnings about unauthorized diabetes management devices circulating outside normal channels, emphasizing that patients should only use devices reviewed by the agency for safety and effectiveness.
The practical legal risk depends on your state. Some states have laws restricting the resale of prescription medical devices. Others don’t address it directly. What’s clear is that selling a used pump privately puts you in a gray zone where platform policies, FDA guidance, and state regulations all create friction. You won’t face a federal enforcement action for selling one personal pump, but you also won’t have legal protections if something goes wrong for the buyer.
Donation and Community Options
If you’re open to giving your pump away rather than selling it, several nonprofit organizations accept donated diabetes supplies, including pumps that are still functional. Organizations like Insulin for Life and CR3 Diabetes collect unused supplies and redistribute them to people without insurance or in underserved countries. Donating may also qualify you for a tax deduction, which can recover some of the value.
Online diabetes communities on Reddit, Discord, and specialized forums sometimes facilitate peer-to-peer exchanges. These aren’t formal marketplaces, and transactions happen at your own risk. The diabetes community is tight-knit, though, and many people have successfully connected with others who needed a specific pump model. Just be aware that any platform hosting these exchanges could change its policies at any time, as Facebook groups discovered.
Preparing Your Pump Before It Changes Hands
Whether you’re trading in, donating, or selling your pump, you need to clear your personal health data first. Your pump stores delivery history, basal rates, carb ratios, and other information tied to your specific treatment. For Medtronic pumps, you can access your device settings and clear saved data through the Settings menu under Device Settings. Other brands have similar reset options in their menus. Check your specific model’s user guide for the exact steps, since the process varies.
Cleaning is the other essential step. The CDC recommends following manufacturer-specific instructions for disinfecting medical devices, since different materials and components may react differently to cleaning agents. Your pump’s user manual will list compatible cleaning solutions. Typically this means wiping the exterior with a lightly dampened cloth and an approved disinfectant, while keeping moisture away from ports and battery compartments. Don’t submerge the device or use harsh chemicals unless the manufacturer specifically says it’s safe.
Remove your infusion set, reservoir, and any accessories. If you’re sending the pump to a manufacturer trade-in program, they’ll handle final processing, but clearing your data beforehand is still a smart precaution.
Which Option Makes the Most Sense
For most people, the answer breaks down by situation. If you’re upgrading to a new pump, a manufacturer trade-in gives you the best combination of value and simplicity, potentially $750 to $1,000 in credits. If your pump is functional but you’ve switched to a completely different management approach (like multiple daily injections), donating to a nonprofit is the path of least resistance and helps someone who needs it. If you’re determined to sell privately for cash, you can find buyers through diabetes community channels, but expect limited buyer protections, platform restrictions, and legal ambiguity that make the process harder than selling typical consumer electronics.
