Medicare Part B Supply List for SNFs
The short answer
- Five categories: surgical dressings (LCD L33831), ostomy supplies (LCD L33828), urological supplies (Policy Article A52521), tracheostomy supplies (LCD L33832), and splints and orthotics (42 U.S.C. § 1395x(s)(5) and (9)).
- Only for residents not in a covered Part A stay. During a covered Part A stay, consolidated billing bundles most supplies into the Part A payment.
- Billed to the A/B MAC on a UB-04 under the facility's institutional NPI. Durable Medical Equipment (DME) is a separate pathway and is excluded.
- Every claim needs a standard written order signed before delivery, a record supporting medical necessity under the LCD, and proof of delivery.
- Enteral nutrition: in some cases, for Medicare Advantage residents when the plan allows it. It is not part of the five Part B categories.
Last updated September 2026
1. Surgical dressings (LCD L33831)
**Coverage:** primary and secondary dressings used on a wound that meets the LCD criteria, such as foam, alginate, hydrocolloid, transparent film and gauze dressings. **Billing rules:** the record needs the wound type, size and stage, and dressing change frequency must match what the LCD allows for that dressing; quantities above the LCD limits need documented justification. Read more: surgical dressing billing and what the record must show.
2. Ostomy supplies (LCD L33828)
**Coverage:** pouches, skin barriers and related ostomy supplies for residents with a colostomy, ileostomy or urostomy. **Billing rules:** quantities follow the LCD's usual monthly maximums, and anything above them needs a documented reason in the record. Read more: ostomy supply billing.
3. Urological supplies (Policy Article A52521)
**Coverage:** intermittent and indwelling catheters, drainage bags and related urological supplies for residents with a documented permanent condition. **Billing rules:** the record must support the type of catheter and the quantity billed, following the policy article. Read more: urological supply billing.
4. Tracheostomy supplies (LCD L33832)
**Coverage:** tubes, inner cannulas, ties and care kits for residents with a tracheostomy. **Billing rules:** the resident must have an open surgical tracheostomy expected to stay open at least three months; care kits are coded A4625 only in the first two weeks, then A4629, and quantities and tube replacement frequency must match the LCD and be supported by the care record. Read more: tracheostomy supply billing.
5. Splints and orthotics (42 U.S.C. § 1395x(s)(5) and (9))
**Coverage:** splints and orthotic devices that meet Medicare's coverage criteria. **Billing rules:** the record must show the medical need for the device and the practitioner's order; off-the-shelf braces have drawn federal scrutiny, so the treating relationship and order must be clear. Read more: splint and orthotic billing.
What is not on this list
Durable Medical Equipment (DME) follows a different statutory pathway and requires DME MAC enrollment, so it is excluded. Supplies used during a covered Part A stay are bundled under consolidated billing and cannot be billed separately. Enteral nutrition is handled only in some cases for Medicare Advantage residents when the plan allows it. See SNF consolidated billing rules.
What every claim needs
A standard written order signed by the treating practitioner before delivery, a contemporaneous record showing the item meets the LCD's reasonable and necessary criteria, proof that the item reached the resident, and confirmation of continued need before recurring items ship. See the step-by-step billing guide, or have Burst handle it through Medicare Part B supply billing.
