Short answer up top, then the exact rule. Here's what Original Medicare does and doesn't cover for an infusion pump in 2026 — and where a Medicare Advantage plan can fill the gap.
Quick answer: Yes. Part B covers infusion pumps and supplies as durable medical equipment when they're medically necessary. That includes some external pumps and some implantable pumps, plus the home infusion equipment — pump, IV pole, tubing, catheters. You pay 20% after the Part B deductible.
Medicare Advantage plans cover the same equipment and drugs, but route them through their own network and prior-authorization rules — and infusion is one of the categories plans most often require authorization for. Confirm the pump, the drug, and the home-infusion supplier are all approved before therapy starts; they can be three separate approvals.
Anyone starting infusion therapy at home, and the family managing it. Worth knowing up front: the equipment and the services are two different Medicare benefits, so ask which one each bill is coming from before you pay it.

See 2026 Medicare Costs →Yes. Part B covers the home infusion equipment and supplies — the pump, IV pole, tubing, and catheters — as durable medical equipment for certain infusion drugs given at home, and Medicare has a separate home infusion therapy services benefit for the related professional services and training. You pay 20% of the Medicare-approved amount after the Part B deductible.
Both external and implantable pumps can qualify when they're medically necessary. Medicare's own examples include an external pump for deferoxamine to treat iron poisoning, an external pump for morphine for cancer pain, and an implantable pump delivering chemotherapy for certain liver cancers.
