Coverage starts with a qualifying wound
Medicare covers surgical dressings when a qualifying wound is present: a wound caused by, or treated by, a surgical procedure, or a wound after debridement.

Calcium alginate and gelling fiber dressings
Alginate and gelling fiber dressings absorb drainage and form a soft gel as they work. PCSS carries both in standard and silver versions, in pads from 2×2 to 10×10 plus rope for depth.

Medicare notes
What applies to wound dressings.
Applied in the office vs. sent home
When a practitioner applies dressings as part of a professional service billed to Medicare, the dressings are included in that service and are not separately payable. Dressings sent home with the patient can be billed on their own claim, with the patient's home as the place of service — not the office.
Policy Article A54563(opens in a new tab)Silver and honey formats
We list silver (Ag) and honey products by their base dressing type. Medicare's surgical dressing LCD lists silver and honey among materials whose safety and effectiveness “have not been established,” and classifies dressings by their clinically predominant component — one made predominantly of such materials isn't considered reasonable and necessary. Code each product by its PDAC listing; choose products on clinical judgment.

Questions
Alginate & gelling fiber: common questions
Net-30 termsNo minimums to startStock orders in the wholesale portal
What's the difference between calcium alginate and gelling fiber?
Both are absorbent primary dressings that gel as they take up drainage. Calcium alginate is made from alginate fibers; gelling fiber dressings use fibers that gel on contact and hold fluid. Both fall in the same HCPCS family, A6196–A6199.
Which HCPCS codes apply to alginate dressings?
Alginate and other fiber gelling dressings are coded by pad size: A6196 (16 sq. in. or less), A6197 (more than 16 up to 48 sq. in.) and A6198 (more than 48 sq. in.). Rope and other fillers use A6199, per 6 inches. Confirm final coding with your billing staff.
How often can alginate dressings be changed under Medicare?
Medicare's surgical dressing LCD (L33831) allows alginate and gelling fiber dressings up to once per day, on a qualifying wound.
