Clinical Policy Title: Bioengineered Skin Substitutes for Ulcers and Wound Care Clinical Policy Number: 16.03.01 Effective Date: Initial Review Date: Most Recent Review Date: Next Review Date: Dec. 1, 2013 March 21, 2013 March 19, 2014 March 2015 Policy contains: • Bioengineered skin substitutes. • Lower extremity ulcers. • Pressure ulcers. • Burns. • Wound care. ABOUT THIS POLICY: Arbor Health Plan has developed clinical policies to assist with making coverage determinations. Arbor Health Plan clinical policies are based on guidelines from established industry sources, such as the Centers for Medicare & Medicaid Services (CMS), state regulatory agencies, the American Medical Association (AMA), medical specialty professional societies, and peer-reviewed professional literature. These clinical policies along with other sources, such as plan benefits and state and federal laws and regulatory requirements, including any state- or plan-specific definition of “medically necessary,” and the specific facts of the particular situation are considered by Arbor Health Plan when making coverage determinations. In the event of conflict between this clinical policy and plan benefits and/or state or federal laws and/or regulatory requirements, the plan benefits and/or state and federal laws and/or regulatory requirements shall control. Arbor Health Plan clinical policies are for informational purposes only and not intended as medical advice or to direct treatment. Physicians and other health care providers are solely responsible for the treatment decisions for their patients. Arbor Health Plan clinical policies are reflective of evidence-based medicine at the time of review. As medical science evolves, Arbor Health Plan will update its clinical policies as necessary. Arbor Health Plan clinical policies are not guarantees of payment. Coverage policy Arbor Health Plan considers the use of specific bioengineered skin substitutes to be clinically proven and, therefore, medically necessary when the following criteria are met: Product Coverage requirements Apligraf® (grafskin) The treatment of infection-free, full-thickness, neuropathic diabetic foot ulcers (DFU) when all of the following are met: • The individual is under current diabetes medical management (including nutritional support and neuropathy treatment) with evidence of stable HgbA1c levels. • The individual has adequate circulation/oxygenation to the affected extremity as evidenced by a palpable pulse on the foot (either dorsalis pedis or posterior tibial artery) or an ankle brachial index (ABI) of 0.7 or greater. • The individual is cognizant and able to participate in, or has a support system to assist with, the follow-up care associated with the treatment of the DFU with Apligraf.

All other uses of bioengineered skin substitutes are considered investigational and unproven, and not medically necessary as their effectiveness has not been established in peer-reviewed professional literature. Limitations Limitations apply to specific skin substitutes based upon the characteristics of each unique product or the absence of rigorous study. The limitations for each referenced skin substitute include those listed below. All other uses of the skin substitutes are not medically necessary. 5 Product Details Apligraf A single application of Apligraf may be all that is required to affect wound healing in those DFUs and VSUs that are likely to improve with this therapy. Additional applications, when less than a 50 percent “take” is observed, are limited to a total of four for the same initially qualified ulcer (for a total of five applications). • Additional applications beyond five in a oneyear period are generally not considered reasonable or medically necessary. • Retreatment within one year following the last successful Apligraf application is generally not considered reasonable or medically necessary. • Retreatment of an ulcer wound, following unsuccessful treatment that consisted of two failed Apligraf applications, is not considered reasonable or medically necessary. Dermagraft A single application of Dermagraft may be all that is required to affect wound healing in those DFUs that are likely to improve with this therapy. Additional applications of Dermagraft are limited to a total of seven for the same initially qualified DFU (for a total of eight applications). • Additional applications beyond eight in a one-year period are generally not considered reasonable, proven or medically necessary. • Retreatment within one year following the last successful Dermagraft application is generally not considered proven or medically necessary. EpiFix, Mimedx, Epifix should not be used for areas of active or latent infection; or if there is a risk of complications. Treatment with EpiFix for conditions beyond FDA approved indications are not covered, as there is insufficient peer-reviewed medical literature to support a conclusion of medical necessity. 6 GRAFTJACKET, OASIS, TheraSkin, PriMatrix • • • • • • Theraskin • All of the skin substitute products contained in this policy are to be used in a manner supported by their respective, specific FDA labeling. Medicare part B accepts the U.S. Food and Drug Administration's (FDA) classification and description of any bioengineered skin substitute. The FDA has regulated most skin substitutes as medical devices. However, some are regulated as human tissue and are therefore subject to the rules and regulations of banked human tissue, not the FDA approval process. The medical record must clearly state the skin substitute product is being used in an office- or clinic-based, comprehensive, organized wound management program. The application of bioengineered skin substitutes is limited to clinicians who are highly skilled in wound care management and have experience in the use of bioengineered skin substitutes for the treatment of wounds. The success of the procedure is somewhat dependent on the skill of the performing provider; therefore, the provider may be subject to a post payment peer review in order to verify his/her qualifications. Debridement and ulcer/wound preparation are considered a part of the material application procedure. Additional applications of the same bioengineered skin substitute occur with two weeks between applications for VSUs, and there should be no fewer than three weeks between applications for neuropathic DFUs, except when more frequent applications are either a part of the FDA product specific labeling instructions, or are clearly supported by medical record documentation of medically reasonable and necessary indications. Treatment with TheraSkin is usually expected to last no more than 12 weeks for any ulcer that initially qualifies for 7 • • • • treatment. Reapplication of TheraSkin within one week for the same ulcer is not considered reasonable or medically necessary: Retreatment with TheraSkin when the initial application has resulted in no decrease in size or increase in granulation tissue, epithelialization or progress towards closing is not considered reasonable or medically necessary. Retreatment within one year following the last successful application with TheraSkin is not considered reasonable or medically necessary. Retreatment of an ulcer following an unsuccessful treatment consisting of two failed TheraSkin applications is not considered reasonable or medically necessary.

Background The skin is the largest organ of the body and provides various functions, such as protection from harmful bacteria, excessive water loss, excretion and temperature regulation. It is composed of two layers, the epidermis and the dermis. The epidermis is the layer that comes into direct contact with the environment and depends upon the dermal layer for numerous structures and support; among these are connective tissue, vasculature to supply nutrients, sensory receptors and glandular activity. When these functions of the skin are disrupted it may become damaged and prone to develop wounds or infections. Ultraviolet sun rays, age and certain disease processes may cause detrimental changes to the skin. Skin grafts have a history of being used to replace damaged or absent areas of dermal tissue associated with disease or injury. Skin grafts may be full thickness (FTSG), involving all the layers of the skin, or splitthickness skin grafts (STSG) that involve the epidermis and a limited amount of the dermis. Autologous skin grafts, or auto grafts, use portions of an individual's own skin and are the least prone to tissue rejection. Though autologous grafts are excellent material for wound repair, their use is dependent upon the amount of healthy skin available. Skin harvesting procedures are painful, invasive and may add stress to an already compromised individual. Temporary skin is provided by the use of allografts, from other human donors, or xenografts, tissue from another animal species such a porcine (pig) or bovine (cow). These temporary skin grafts must be replaced with an autograft. Bioengineered skin substitutes were developed to address the problems encountered with the use of allografts, autografts and xenografts. These products are known by names such as tissue-engineered skin substitutes, skin alternatives and skin equivalents. Bioengineered products contain natural or synthetic matrix scaffolds composed of fibroblast or keratinocyte cells that provide a mechanically stable framework and tissue infiltration. Human skin substitutes are manufactured using selected human cells that are placed into a matrix and provided with nutrients for the cells to grow into the desired tissue. Skin substitutes have been developed to meet the needs of individuals with insufficient skin for grafting. They are designed to temporarily assume the functions of the dermal layers until an individual’s own skin repairs itself or until a skin replacement is found. 9 Bioengineered skin substitutes are approved for use in certain types of non-healing wounds and have been used for a variety of chronic wounds with the aim of reducing infection and promoting faster healing — beneficial clinical effects associated with complete wound closure. Venous stasis ulcers and diabetic foot ulcers are two types of chronic, non-healing wounds that affect all types of demographic groups. Bioengineered skin substitutes are classified into four main groups: 1. Human- and human/animal-derived bioengineered skin substitutes regulated through FDA premarket approval process (PMA) or humanitarian device exemption (HDE). 2. Human-derived bioengineered skin substitutes regulated as human cells, tissues, and cellular and tissue-based products. 3. Animal-derived bioengineered skin substitutes regulated through FDA 510(k) process. 4. Biosynthetic bioengineered skin substitutes regulated through FDA 510(k) process. Apligraf (grafskin) and Dermagraft are human/animal-derived bioengineered skin substitutes regulated through FDA premarket approval process (PMA) or humanitarian device exemption (HDE) as a manufactured viable bilaminate. Apligraf is a composite, bilayered product derived from human neonatal foreskin in a bovine matrix. Studies confirm that Apligraf combined with compression therapy improves healing times for venous stasis wounds. Dermagraft is a dermal replacement derived from human neonatal foreskin fibroblasts, and is FDA-approved for use in diabetic foot ulcers (DFU). EpiFix is amniotic membrane used for diabetic foot ulcers. Amniotic membranes are obtained post-partum, cleaned, sterilized and dehydrated for storage. The FDA classifies these as banked human tissue and regulates them under Section 361 of the Public Health Services Act. GRAFTJACKET Regenerative Tissue Matrix, EpiFix and TheraSkin are human-derived bioengineered skin substitutes regulated as human cells, tissues, and cellular and tissue-based products. GRAFTJACKET Regenerative Tissue Matrix is derived from cadaver skin and has been studied for use in individuals with DFUs. EpiFix is derived from amniotic cell lines. OASIS Wound Matrix and PriMatrix are animal-derived bioengineered skin substitutes regulated through FDA 510(k) processes. OASIS Wound Matrix is a natural extracellular matrix derived from porcine small intestinal submucosa that replaces the human body's absent or damaged extracellular matrix. It contains collagen, elastin, etc., is compatible with human tissue and has FDA approval for use in the treatment of partial- and full-thickness wounds, such as diabetic ulcers, venous stasis ulcers and other surgical wounds. Methods Searches Arbor Health Plan searched PubMed and the databases of: • UK National Health Services Centre for Reviews and Dissemination. • Agency for Healthcare Research and Quality’s National Guideline Clearinghouse and other evidencebased practice centers. • The Centers for Medicare & Medicaid Services. The search terms were “skin substitutes” and “wound care.” We included: • Systematic reviews, which pool results from multiple studies to achieve larger sample sizes and greater precision of effect estimation than in smaller primary studies. Systematic reviews use predetermined 10 • • transparent methods to minimize bias, effectively treating the review as a scientific endeavor, and are thus rated highest in evidence-grading hierarchies. Guidelines based on systematic reviews. Economic analyses, such as cost-effectiveness, and benefit or utility studies (but not simple cost studies), reporting both costs and outcomes — sometimes referred to as efficiency studies — which also rank near the top of evidence hierarchies. Overview of the literature — systematic reviews/guidelines and economic analyses for bioengineered skin substitutes: reverse chronological order and then alphabetically by first author. Summary of findings While the methodologic quality of the literature is generally poor, it has recently improved sufficiently for cautious conclusions that skin substitutes are safe and at least as effective as standard treatments. Citation Content Hayes (2013) OASIS Wound Matrix for lower extremity ulcers: • 3 RCTs and one quasi. • Low-quality evidence for improved healing. Hoogewerf (Cochrane; 2013) Topical treatment for facial burns: • RCTs, 1980 ‒ 2012. • Five trials (119 subjects) — two for antimicrobial agents, three for skin substitutes. • All high risk of bias. • Insufficient evidence. Wasiak (Cochrane; 2013) Dressings for superficial and partial thickness burns: • RCTs; 2012. • Thirty trials — generally poor quality. • Trials too heterogeneous for conclusions. Snyder (AHRQ; 2012) Skin substitutes for chronic wounds: • Eighteen RCTs — 12 DFU; six VSU; one pressure ulcer. • Overall moderate/low quality. Buchberger (2011) Growth factors and active skin substitutes for non-infected diabetic foot ulcers: • Publications since 1990. • Could be alternatives to standard wound treatment alone but weak evidence precludes firm conclusions. UK National Institute for Clinical Excellence (NICE) (2011) Inpatient management of diabetic foot problems: • Economic evaluations — Feb 2010. • Hospitals should have multi-disciplinary foot care teams (diabetologist and nurse specialist, surgeon, podiatrist, tissue viability nurse, and access to other specialist services) for diabetics with foot ulcers. • Wound dressing choice should take into account clinical assessment of wound, patient preferences and acquisition cost. 11 Citation Content • NOT recommended: dermal or skin substitutes, autologous platelet-rich plasma gel, regenerative wound matrices, growth factors, hyperbaric oxygen. Hayes (2010) Skin substitutes for wound healing (limited number of moderate quality RCTs): • Apligraf — in conjunction with standard therapy for non-infected chronic lower extremity ulcers for whom standard therapy is ineffective. • Biobrane — pediatric patients with non-infected partial thickness burns < 25% of body surface area. • Dermagraft — in conjunction with standard therapy for DFUs > 3 weeks and not responsive to standard therapy alone. Barber (Australian Safety and Efficacy Register of New Interventional Procedures - Surgical [ASERNIP-S]; 2008) Flack (2008) Skin substitutes for diabetic foot ulcers and venous leg ulcers: • RCTs; July 2008. • 18 poor/moderate quality trials (1,909 subjects). • Products with dermal component may improve healing. Barber (ASERNIP-S ; 2006) Bioengineered skin substitutes for wound management: • Evidence based rated average; limited by small sample sizes, short follow up time and general lack of methodologic rigor for all three indications (epidermal, dermal or both). • Safety — suggests that substitutes at least as safe as standard therapies for diabetic foot ulcers and venous leg ulcers but data insufficient for long-term outcomes judgment. Pham (ASERNIP-S; 2006) Bioengineered skin substitutes for burns: • RCTs — 2006. • Insufficient evidence. Economic evaluation: closure of partial thickness facial burns with bioactive skin substitute: • Effectiveness based on one low-quality RCT (34 subjects, no power calculation or randomization methods reported). • Skin substitutes cost-effective compared to current practice. Demling (2002) Economic evaluation: Vacuum-assisted wound closure vs. alternatives including Apligraf and Dermagraft for diabetic foot ulcers: • Markov model; one year horizon and data from RCTS. • No studies directly compared VAC to skin substitutes but VAC appears to be more effective and less expensive than alternatives. Glossary Reapplication — An additional application of a skin substitute to the same ulcer within the same treatment period. 12 Retreatment — A new treatment period in which the same ulcer is treated again because the initial treatment was apparently unsuccessful.
