What Wound Care Services Does Medicare Cover?

Medicare Part B covers a broad range of wound care services when they are medically necessary and properly documented. The coverage is real and the reimbursement rates support a viable wound care practice -- but each service category has specific requirements that determine whether the claim pays or denies. Here is what is covered, what conditions apply, and where the common pitfalls are.

Evaluation and Management Visits

Covered. Wound care E/M visits are covered under standard office and outpatient visit codes (99202-99215) as well as home visit codes (99341-99345 for new patients, 99347-99350 for established patients). Place of service determines the code set -- POS 12 for home visits, POS 31 for SNF visits, POS 11 for office-based wound care.

Home visits are a particular strength for mobile wound care providers. Medicare reimburses home visit codes at rates that reflect the additional time and resources required to deliver care outside a clinical facility. A home visit E/M code paired with a debridement procedure on the same encounter is a common and well-supported billing pattern.

Debridement

Covered. Medicare covers both selective debridement (97597/97598 -- sharp selective debridement of devitalized tissue) and surgical debridement (11042-11047 -- debridement by tissue type and depth). The CPT code selection depends on the depth of tissue removed and the wound bed characteristics.

The documentation requirement is specific: the note must describe the type of tissue debrided, the instrument used, the depth reached, and the clinical rationale for debridement. A wound bed with 100% granulation tissue does not support a debridement claim. The wound bed description in the encounter note must be consistent with the procedure billed.

Skin Substitutes

Covered with LCD compliance. Cellular and/or tissue-based products (CTPs) -- commonly called skin substitutes or skin grafts -- are covered when applied in accordance with the applicable Local Coverage Determination. LCD requirements typically include documented failure of conservative therapy for a defined period (usually 30 days), a wound that meets size and depth criteria, and appropriate wound bed preparation.

Medicare Advantage plans may require prior authorization for skin substitute application even when the LCD criteria are met. Traditional Medicare generally does not require prior authorization for CTPs, but the LCD documentation requirements function as a prospective coverage standard -- if the documentation does not demonstrate LCD compliance at the time of the encounter, the claim is vulnerable to post-payment denial.

Negative Pressure Wound Therapy (NPWT)

Covered. NPWT (wound VAC therapy) is covered under Medicare Part B for wounds that have failed to respond to conservative treatment. The critical documentation requirement: at least 30 days of prior conservative wound therapy must be documented before NPWT initiation, unless the wound presents with acute characteristics that justify immediate NPWT (surgical dehiscence, traumatic wounds, certain flap or graft failures).

The 30-day conservative therapy requirement is the most common reason NPWT claims are denied. The documentation must show specific conservative treatments attempted, the duration of each, and the wound's failure to respond. Vague notes stating "wound has not improved with conservative care" are insufficient -- the prior treatment must be itemized with dates.

Hyperbaric Oxygen Therapy (HBOT)

Covered for specific indications. HBOT is covered under Medicare Part B for a defined list of conditions. For wound care, the primary covered indication is diabetic foot ulcers classified as Wagner grade 3 or higher that have failed 30 days of standard wound therapy. The wound must be of adequate size and severity, and the patient must have adequate vascular status to benefit from hyperbaric treatment.

HBOT coverage is narrower than many providers expect. Not all chronic wounds qualify -- the indication list is specific, and the documentation requirements for demonstrating failed conservative therapy are rigorous.

Compression Therapy

Covered. Application of compression bandaging systems (29580/29581) is covered for venous leg ulcers and wounds with venous insufficiency as a contributing factor. Adequate arterial perfusion must be documented before compression is applied -- an ABI (ankle-brachial index) of >0.5 is generally required to demonstrate safe arterial status for compression.

What Is NOT Separately Billable

Several wound care activities are part of the E/M service and are not billed as separate line items:

Routine dressing changes. Applying a standard wound dressing during an E/M visit is included in the E/M service. It does not generate a separate CPT charge.
Basic wound care supplies. Gauze, tape, saline irrigation, and standard dressings used during the encounter are bundled into the service. Advanced wound care products (CTPs, NPWT supplies) are billed separately under their respective codes.
Wound photography. Clinical photographs are a documentation element, not a billable service. There is no CPT code for wound photography.
Patient education. Teaching the patient or caregiver about wound care, dressing changes, or offloading is part of the E/M service.
