Sunflower Health Plan Burn Surgery (PDF) Form

Early burn debridement is vital to the overall survivability and outcome of burn patients. Early grafting is also directly related to improved survival rates.12 Grafts used to cover the wound bed include skin replacements (i.e., autograft and allograft) and skin substitutes. Autografts (split or full thickness skin grafts) are the current standard of care in burn surgery. When the total body surface area is larger than the available donor sites or tissues are too edematous to allow successful acceptance of autografts, allograft and skin substitutes are an alternative. Skin substitutes are tissue-engineered products designed to replace, either temporarily or permanently, the form and function of the skin. This policy addresses the medical necessity criteria for burn debridement and/or excision and the use of skin substitutes for burns during the acute phase of treatment. Note: For skin substitutes for chronic wounds, refer to CP.MP.185 Skin Substitutes for Chronic Wounds. Policy/Criteria I. It is the policy of health plans affiliated with Centene Corporation® that burn treatment with debridement and/or excision is medically necessary for either of the following: A. Deep partial-thickness burn; B. Full-thickness burn or deeper. II. It is the policy of health plans affiliated with Centene Corporation that burn treatment with skin replacement/substitutes (including the procedure, product, service) is medically necessary when meeting all of the following: A. Sufficient autograft is not available at the time of excision or is not feasible due to the physiological condition of the patient; B. No evidence of burn wound infection; C. Treatment with any of the following skin replacement/substitutes: 1. Allograft (human cadaver); 2. Xenograft (porcine); 3. Tissue engineered skin substitute (e.g., Biobrane®, Transcyte®, Apligraf®, TheraSkin®, Integra® Wound Matrix, Integra® meshed Bilayer Wound Matrix, Integra® Dermal Regeneration Template, or Epicel,® if used per FDA HDE). Background Johns Hopkins Health Library defines a burn as a type of painful wound caused by thermal, electrical, chemical, or electromagnetic energy. They cite smoking and open flame as the leading causes of burn injury for older adults and scalding as the leading cause of burn injury for children.1 According to the American Burn Association, burn injuries result in more than Page 1 of 7 CLINICAL POLICY Burn Surgery 500,000 hospital emergency department visits and approximately 50,000 acute admissions per year in the United States. The most severe burn injuries require admission to a specialty hospital or burn center.2 A severe or major burn is classified as any burn that is accompanied by a major trauma, inhalation injury, or a chemical or high-voltage electrical burn. Also considered severe are any burns involving over 20 percent of the total body surface area (TBSA), with the exception of first-degree burns. Burns to high-risk individuals such as older adults, young children and anyone with a major comorbidity may be considered severe even if less than 20 percent of their TBSA is involved. Burns to areas like the eyes, ears, face, hands, feet or perineum may require specialized burn center care due to the high risk of functional impairment.3 In addition, circumferential burns of the extremities or thorax require a consultation with a burn center as they are an indicator of decreased blood flow. Deep circumferential burns of the chest may impair or prevent mechanical ventilation of the burn victim.4 Burns are classified in terms or degrees. First-degree burns, also called superficial partial thickness, only involve the outer layer of skin, the epidermis. These burns will be red and painful but remain dry and without blisters. First-degree burns typically heal within about one week. Second degree, or partial thickness burns, extend deeper into the dermis, include blisters, and have a wet appearance. Second-degree burns are extremely painful and can take two to three weeks to heal. Third degree, or full thickness, burns have a white or leathery appearance and will be dry to the touch. These burns are often without sensation due to nerve damage. They extend the full depth of the skin. Skin grafts are typically required for healing third degree burns. The most severe burns are called fourth degree or are classified as with extension to deep tissues. These burns will extend to the muscles, tendons and/or bone. Skin grafting and even more intensive surgeries or amputations may be required for healing.4 In the past, burns were treated with painful debridement of blisters, daily soaking and scrubbing, and frequent bandage changes with topical medications. Today, tissue regeneration and grafting is rapidly becoming the new standard of care in burn injuries.3,5,6 The goal of burn treatment is to replace damaged or missing tissue with similar, healthy tissue and restore full function to the involved area with minimal to no scar tissue formation.13 Second, third and fourth degree burns most often require a surgical procedure to allow for healing. Although some of the most severe burns may require multisystem surgeries or amputations, most burn injuries are treated with the application of skin grafts.3,5,6 One of the greatest advances in burn treatment has been early excision of necrotic tissue and closure of thermal burn wounds. Early excision and grafting provide a skin substitute for the wound, but further reconstructive surgeries may still be required to restore a normal appearance and function.7 According to the International Society for Burn Injury (ISBI), management of major burns by debridement with dressings and subsequent delayed grafting may be the safest approach when resources are limited. By waiting until sloughing of the eschar has happened, minimal surgery is needed, with harvest of the skin grafts being the key surgical intervention.13 Hydrosurgery describes the use of high-pressure water jets to debride necrotic tissue. This technique aids in dermal skin preservation and scar reduction with twice as many patients, who noted a difference, reporting the hydrosurgically debrided area to be better or much better at 12 Page 2 of 7 CLINICAL POLICY Burn Surgery months, and one-fourth of patients saw no difference. Although encouraging, additional larger trials are necessary prior to recommendations for routine use.9 By performing early excision and grafting, the patient’s length of stay in the hospital is significantly reduced, as is the risk for hypertrophic scarring, joint contracture, infection and stiffness. Early closure also allows for quicker rehabilitation and lower mortality rates. As with any surgical procedure, there are also risks and challenges. Major challenges associated with burn surgery include extensive tissue loss and limited availability of tissue, exposure of other structures, scarring and limited tissue pliability.7 Skin Grafts Skin grafting consists of taking tissue from another source and placing it over a wound. Sources include unaffected skin from another location on the burn victim’s body, cadaveric skin grafts and amniotic chorion/membrane. The success of a skin graft relies on many factors. The graft bed must be suitable to sustain the graft during the imbibition phase of healing. Also, there must be sufficient perfusion to the graft, either from the graft bed or from another supply such as a flap repair. Skin grafts are used for coverage of exposed bone and tendons only if there is a vascularized layer of periosteum or the paratenon is intact.7,8 Coding Implications This clinical policy references Current Procedural Terminology (CPT®).
