SkinTE is a fully autologous (from the patient for the patient) homologous (performing the same basic functions of skin tissue) skin construct intended to be used by physicians or other appropriate health care providers for homologous uses of the skin and integumentary system. Patients who have suffered from an event, disease, process or who have an acquired defect that has resulted in the functional loss or absence of the skin and integumentary system can use SkinTE as an adjunct and/or in place of split-thickness skin grafting, full-thickness grafting, temporizing skin coverage, skin substitute products or even vascularized free tissue transfer in some cases. Each SkinTE is intended for autologous use that is patient-specific, a single application and contains no allogeneic or xenogeneic tissue. SkinTE has been shown to regenerate permanent full-thickness (epidermis, dermis, hypodermis), hair-bearing skin with all its associated appendages.

SkinTE is processed aseptically under current Good Tissue Practice (cGTP) in a controlled clean room environment at an FDA-registered manufacturing facility. SkinTE manufacturing follows the rigorous quality control testing per FDA regulations.

Regulatory:SkinTE is FDA-registered as a human cells, tissues and cellular and tissue-based product (HCT/P) marketed solely under Section 361 of the Public Health Service Act and its implementing regulations under 21 CFR 1271. PolarityTE is registered with the U.S. Food and Drug Administration (FDA) as a tissue establishment for SkinTE. SkinTE is manufactured under Current Good Tissue Practice (cGTP) guidelines compliant per FDA regulations.

Intended Use:SkinTE is intended to be used by licensed medical professionals for homologous uses of skin tissues which may include the repair, reconstruction, replacement or supplementation of skin tissues and the integumentary system. SkinTE may be used to treat patients who have suffered from an event, disease, process or acquired deficit that results in the functional loss or void of skin tissues and the integumentary system in place of or in combination with split-thickness grafting, full-thickness grafting, temporizing skin coverage and/or skin substitute products. SkinTE has been used for the autologous, homologous treatment of skin tissue in the following conditions:

• Wounds (acute & chronic)

• Surgical reconstruction events

• Burns (acute, subacute & burn reconstruction)

• Scar Revision

• Traumatic Injuries

• Replacement of skin grafts or failed flap coverage

Harvest Size:SkinTE is manufactured from a small harvest sample of the patient’s full-thickness skin which is dependent on wound defect size and is shipped back to an FDA-registered manufacturing facility. The quantity of SkinTE developed is patient-specific and customized based upon the patient’s wound defect size. A 1 cm2 full-thickness skin harvest can generate SkinTE which can cover up to 10% of the patient’s total body surface area (TBSA). The application of SkinTE is a single application with no wastage. SkinTE can be returned as soon as the same day of harvest but is typically shipped back to the provider within 48–72 hours.

Deployment Size:SkinTE is supplied as an autologous, homologous skin product in an amount appropriate for the target wound surface area for treatment and is spread evenly across the treatment area. Following SkinTE application across the wound bed, it is secured in place per standard of care for skin grafting procedures and dressed accordingly.

Product Wastage:SkinTE is manufactured based on each individual patient’s wound size. The development of the autologous homologous skin product is customized for each patient’s defect, therefore, no wastage of product.

SkinTE™ Product Description

The Process for SkinTE Use is as Simple as:

1. Harvest Skin Specimen: Provider harvests a small piece of full-thickness skin and places the specimen in a provided PolarityTE Harvest shipping container and sends back to PolarityTE.

2. Manufacture SkinTE: The patient-specific skin harvest specimen is utilized to manufacture the SkinTE cell-tissue product in a PolarityTE manufacturing facility.

3. Ship SkinTE to Provider: The skin product is contained within a syringe and is then returned back to the provider and patient, typically within two days.

4. Apply SkinTE to Wound Defect: The patient-specific SkinTE product arrives in an all-inclusive SkinTE Deployment Box at the chosen facility and is applied to a prepared wound bed and dressed with included materials.

SkinTE Product Code

The Healthcare Common Procedure Coding System (HCPCS) level II codes are used for the reporting and billing of non-physician services. SkinTE has a unique product HCPCS code that was established January 1, 2019.

Current Procedural Terminology (CPT®) Coding

The Current Procedural Terminology (CPT) code set describes medical, surgical and diagnostic services and is maintained by the American Medical Association. These codes are designed to communicate standardized information about medical services and procedures.

The application of SkinTE is performed in two phases: a harvest phase and a deployment phase. The selection of an appropriate CPT code is based on the location and size of the patient’s wound defect and supported by the patient’s medical record. CPT add-on codes and modifiers may also be applicable.

Some CPT codes contain add-on codes for additional same procedures. These codes must be reported along with the primary procedure codes. Coding modifiers may also apply. Coding modifiers according to the AMA and CMS provides the means to report that a service or procedure has been performed or altered by some specific circumstance without changing the definition of the code. Due to the staged nature of the SkinTE service, it may be appropriate to report modifiers in addition to the procedure codes to identify reduced services or staged procedures. Please check with the patient’s insurer or Medicare Administrative Contractor (MAC) to inquire if modifiers are required with the CPT codes used. Potential CPT codes and modifiers are listed below.

Payment in the Outpatient setting (HOPD/ASC) is governed by the Hospital Outpatient Prospective Payment System (OPPS) and the Ambulatory Surgical Center (ASC) Payment System. Specific CPT codes are cross walked to specific facility payments under the Ambulatory Payment Classification (APC) and ASC. SkinTE is currently bundled into the facility payments for these procedures, and there is no separate payment. Providers and facilities should use the CPT codes and corresponding APC codes that are most relevant and appropriate for the procedures performed for both the harvest and deployment phases when using SkinTE.

Sample Prior Authorization Letter

[DATE]

[NAME OF INSURANCE COMPANY][ATTN:][FAX #:]

RE: [PATIENT NAME][INSURANCE IDENTIFICATION NUMBER][DATE OF BIRTH]

Dear Medical Director,

I am writing this letter as a pre-authorization request to provide an autologous homologous skin product to my patient [NAME Jane Doe]. This patient has a defect located on [defect location]. Conservative methods of treatment and standard of care therapy have failed in providing adequate healing, and it is medically necessary to change the plan of care and use the autologous, homologous skin product at this time.

[PATIENT NAME] medical history is the following:

• [AGE] [GENDER] who presented to me with [DESCRIBE SYMPTOMS WITH SPECIFICITY].

• [PRIMARY DX:]

• This patient’s comorbidities of [DESCRIBE, SUCH AS DIABETES, ETC.] have impacted the healing process.

• Prior treatments have included [DESCRIBE CONSERVATIVE CARE, USE OF MEDICATIONS, PRIOR TREATMENTS].

• Factors that influence healing have been addressed: [ i.e. VASCULAR STATUS, NUTRITIONAL STATUS, INFECTION, ETC.]

• The size of the patient’s defect [LENGTH (CM) X WIDTH (CM) X DEPTH (CM)] over the course of treatment

I believe the best course of treatment and medical necessity for this patient is the application of SkinTE™, the only currently available autologous homologous skin product, and it will provide a clinically effective and cost-effective therapy.

SkinTE is a fully autologous (from the patient for the patient), homologous (performing the same basic functions of skin tissue) cutaneous construct which facilitates the regeneration of permanent full-thickness skin and is intended for the repair, reconstruction and replacement of skin. SkinTE is regulated by the U.S. Food and Drug Administration (FDA) as a human skin tissue under its Human Cells, Tissues and Tissue-Based Products (HCT/P) guidelines.

The procedure to create and apply SkinTE involves harvest of a small full-thickness skin graft from an area of the patient’s healthy skin. This small harvest is sent to an FDA-regulated manufacturing facility where it is developed into SkinTE, shipped back to the provider to deploy in a single application, then secured over the wound bed and dressed accordingly. SkinTE is personalized for each patient’s wound size and allows for no product wastage. The use of this autologous homologous skin product will allow me to treat this patient [IN THE PRACTICE SETTING] and avoid other more costly therapies such as [WEEKLY APPLICATIONS OF A SKIN SUBSTITUTE OR ADVANCED WOUND CARE THERAPY OR USE OF OPERATING ROOM TIME AND RESOURCES FOR SKIN GRAFTING].

SkinTE is able to generate complete epithelial coverage and full-thickness skin demonstrating cutaneous appendages. Please refer to the included references and figures which showcase the spectrum of wounds treated with SkinTE. Should you have further questions or require additional information, please do not hesitate to call me.

Thank you for your immediate attention and anticipated authorization of these services for your insured member.

Sincerely,

[PHYSICIAN NAME], MD[PHONE NUMBER][BOARD CERTIFICATION][IN NETWORK]Tax ID:NPI #:

Spectrum of Wounds

Initial Wound: The patient suffering from necrotizing fasciitis was left with an open wound with exposed muscle and tendon over his right lower extremity following surgical debridement. Refractory wounds following split-thickness skin grafting were treated with SkinTE in the provider’s clinic.

Mid-Stage Healing of SkinTE: Three months following the single application of SkinTE in the clinic, the patient returned for routine follow-up. SkinTE regenerated full-thickness, functional skin within the wound bed and covered the previously exposed muscle and tendon. The donor site, which was closed primarily at the time of harvest, was also completely healed.

Acute Wound

Chronic Wound

Initial Wound: Following a traumatic crush injury, the patient was left with a refractory wound over his left lateral foot. SkinTE was deployed into this defect in the provider’s office.

Mid-Stage Healing of SkinTE: Six months following the application of SkinTE in the office, the patient experienced full-thickness, functional skin regeneration within the wound bed and the previously exposed bone was covered. The donor site, which was closed primarily at the time of harvest, was also completely healed.

Post-Mohs Reconstruction

Diabetic Foot Ulcer (DFU)

Initial Wound: Following Mohs surgical excision, the patient was left with a full-thickness skin defect with exposed muscle over her philtrum. Due to her history of complications with traditional local flap reconstruction, the patient elected to utilize SkinTE.

Initial Wound: The patient had a full-thickness, persistent DFU over his left foot with exposed bone. The patient’s wound failed conservative measure of treatment and, with the presence of exposed bone, presented a risk of underlying infection of the bone and made conventional treatment with skin grafting problematic. The provider elected to utilize SkinTE in the office.

Early-Stage Healing: One month following SkinTE deployment (done in the office), the patient experienced full-thickness skin regeneration over her exposed muscle with full three-dimensional contour restored without distorting the critical anatomical landmarks of the face. The donor site, which was closed primarily at the time of harvest, also healed completely.

Mid-Stage Healing: Four months following SkinTE deployment in the office, the patient experienced full-thickness skin regeneration over his exposed bone. The donor site, which was closed primarily at the time of harvest, also healed completely.

Acute Traumatic Wound

Mid-Stage Healing of SkinTE: Three months following the single application of SkinTE, SkinTE regenerated full-thickness functional skin within the wound bed and covered the previously exposed muscle, bone and tendon. The patient experienced limited donor site morbidity. The range of motion of her foot remained intact.

Initial Wound: Following a lawnmower injury, the patient was left with a wound on her right heel with exposed muscle, tendon and bone. SkinTE was deployed into this defect.

STSG Replacement

Traumatic Injury

Mid-Stage Healing of SkinTE: Five months following the single deployment of SkinTE, SkinTE had generated full-thickness, hair-bearing skin within the fibrotic wound.

Mid-Stage Healing of SkinTE: Four months following a single application of SkinTE, SkinTE regenerated full-thickness functional skin within the wound bed and covered the previously exposed joint, bone, muscle and tendon. The patient experienced limited donor site morbidity. The range of motion of his foot remained intact.

Initial Wound: Following excision of the fibrotic skin graft, the patient was left with a large defect over the left chest with exposed pectoral within a scarred wound bed. SkinTE was deployed into this defect.

Initial Wound: Following a motor vehicle collision, the patient was left with a full-thickness wound on his left foot with exposed joint, bone, muscle and tendon. SkinTE was deployed into this defect.

Initial Wound: 2-year-old female who suffered acute scald burns to both arms, legs and chest presented to the Burn Unit.

Early-Stage Healing: One month following the acute scald burns, full-thickness skin regeneration is seen over areas that failed initial treatment with split-thickness skin grafts.
