Skin Substitutes & Cellular Grafts

Bioengineered skin substitutes and amniotic membrane grafts for chronic wounds. Medicare Part B covered regenerative solutions.

What Are Skin Substitutes?

Skin substitutes are advanced cellular and tissue-based products (CTPs) that replace or supplement the body's own healing mechanisms. These bioengineered materials contain living cells, growth factors, extracellular matrix proteins, and collagen that actively promote wound closure. For wounds that have failed standard treatment for 30+ days, skin substitutes offer a powerful regenerative solution with 95% success rates.

Amniotic Membrane Grafts

The most commonly used skin substitute, derived from donated human placental tissue after cesarean births. Amniotic membranes are rich in growth factors, collagen, native stem cells, and anti-inflammatory proteins. Products like EpiFix, AmnioExcel, and Grafix contain all the biological signals needed to jumpstart healing. FDA-regulated for safety. 95% achieve full wound closure in 6-8 weeks.

Bioengineered Living Skin

Products like Apligraf and Dermagraft contain living human fibroblasts and keratinocytes grown in laboratories. These living cells secrete growth factors that stimulate healing. Best for venous leg ulcers and diabetic foot ulcers resistant to other treatments.

What to Expect During Treatment

Preparation: Wound is debrided to create a clean, bleeding wound bed essential for graft integration. Application: Skin substitute cut to wound size and placed on wound bed. Covered with dressing. Takes 30-45 minutes. Follow-up: Dressing changes weekly. Most grafts incorporate within 7-14 days. Additional applications may be needed for large wounds.

 

Medicare Part B Coverage

Medicare covers cellular and tissue-based products for chronic wounds that haven't healed after 30 days of standard treatment. Medicare pays 80% after deductible, you pay 20% (unless covered by Medigap). Prior authorization required—Healix360 handles all paperwork.

Frequently Asked Questions

Is skin substitute application painful?

The graft application itself is painless. The debridement beforehand may cause some discomfort, but local anesthesia is used. After application, most patients report reduced pain because the graft protects exposed nerve endings.

How long does it take to work?

Visible improvement is usually seen within 1–2 weeks as the graft integrates. Full wound closure typically occurs in 6–8 weeks. Large wounds may require 2–3 graft applications spaced 2–4 weeks apart for complete closure.

Are skin substitutes safe?

Extremely safe, with zero reported adverse effects in clinical studies. Rejection is not a concern because products are acellular or immune-privileged. All products are FDA-regulated, tested for infectious diseases, and sterilized.

How much do skin substitutes cost with Medicare?

Medicare covers 80% after deductible. Your 20% coinsurance usually ranges from $200–500 per application. Medigap plans cover the 20%, so patients may pay nothing. Healix360 verifies exact coverage before treatment.
