Does insurance cover a broken-bone cast?

For most of what's on this checklist, the real answer runs through your FSA or HSA, not an insurance claim — except crutches, which are the one item Medicare or insurance can actually help pay for directly. The cast or splint itself never shows up in Medicare's equipment data at all, and that's not a gap in this site's dataset — it's genuinely billed a different way.

The fact

Casts and splints are billed clinically — a CPT procedure code, part of the ER or urgent-care visit itself — not through Medicare's DME fee schedule. Searching this site's own 68-code coverage_status.json dataset for "cast," "splint," or "fracture" returns zero hits.

That's correct, not a gap: applying a cast or splint is a clinical service, not a piece of durable medical equipment. The one genuine exception on this whole checklist is crutches, covered below.

The one exception: crutches

If a broken leg means you need crutches, that's the one item on this checklist where Medicare's rules actually help.

“Crutches underarm, other than wood, adjustable or fixed, pair, with pads, tips and handgrips.”

Crutches, underarm, non-wood, pair, with pads/tips/handgrips E0114 $57.17–$88.73 $11.43–$17.75 44,541

Policy citation: Canes and Crutches (A52459). A prescription (a Written Order Prior to Delivery, on file before the item is handed over) is required, the same rule that applies across every DME category Medicare covers.

Everything else: no code exists

Waterproof cast covers, sling comfort pads, wedge/leg-elevation pillows, and cast-specific ice wraps all return zero hits in this site's own 68-code dataset — not a code that pays $0 by rule (like a shower chair), but no billing code assigned to the category at all. Buy them retail; there's no prescription path and no coinsurance math to run for these.

FSA and HSA: the broader, more useful rule for most readers

This is the bigger story for most people on this checklist, especially parents managing a child's cast — Medicare simply doesn't apply to most of this hub's readers, but IRS Publication 502's medical-expenses definition does.

The IRS rule

Crutches — You can include in medical expenses the amount you pay to buy or rent crutches.

Named explicitly, by category, in IRS Publication 502 — the strongest, most directly on-point FSA/HSA citation available for this checklist. Publication 502's medical-expense list is the same IRC §213(d) definition that governs what FSA and HSA funds can reimburse tax-free (cross-referenced in IRS Publication 969).

“Bandages — You can include in medical expenses the cost of medical supplies such as bandages.”

— IRS Publication 502, Medical and Dental Expenses

That's a real, named, adjacent category to the cast padding and dressing supplies used to treat a fracture — not this site inferring eligibility by analogy. And Publication 502's general definition covers the visit itself, without needing a cast-specific line item:

“Medical expenses are the costs of diagnosis, cure, mitigation, treatment, or prevention of disease and for the purpose of affecting any part or function of the body. These expenses include payments for legal medical services rendered by physicians, surgeons, dentists, and other medical practitioners. They include the costs of equipment, supplies, and diagnostic devices needed for these purposes.”

— IRS Publication 502, “What Are Medical Expenses?”

An ER or urgent-care visit for a fracture is squarely "treatment... for the purpose of affecting a part of the body," so it qualifies without a cast-specific line item in Publication 502. Save every receipt — the visit itself, the crutches, and the medical supplies used to treat the injury are all reimbursable this way.

What this rule does — and doesn't — confirm

Publication 502 confirms the ER/urgent-care visit, crutches, and general medical supplies (bandages) are FSA/HSA eligible. It does not automatically extend to every product on this hub's checklist by name — this research pass did not run a per-item marketplace eligibility check (an FSAstore.com listing check) for the waterproof cast cover, sling pad, or wedge pillow specifically. Those items likely qualify under the same general medical-supplies logic, but we're stating that as a reasonable inference, not a confirmed per-item fact — check your own FSA/HSA administrator or a marketplace like FSAstore.com before assuming a specific product qualifies.

This page explains what Medicare's published rules and IRS Publication 502 say — it isn't a coverage determination for your specific claim or plan. FSA and HSA plan rules vary by employer and administrator; confirm your own plan's eligibility list before you buy. A Medicare Advantage plan can set different rules than the Original Medicare figures cited here.
