CPT® Code 15014

1. Indications

The preparation of a skin cell suspension autograft (SCSA) is indicated for the treatment of partial-thickness wounds. These wounds may arise from various conditions, including but not limited to:

• Burns: Partial-thickness burns that damage the epidermis and part of the dermis, requiring skin grafting for proper healing.
• Trauma: Wounds resulting from accidents or injuries that compromise the skin integrity and necessitate grafting for recovery.
• Chronic Ulcers: Non-healing wounds, such as diabetic ulcers or venous stasis ulcers, that may benefit from skin grafting to promote healing.

2. Procedure

The procedure for preparing a skin cell suspension autograft involves several detailed steps to ensure the effective harvesting and processing of skin cells. The first step involves the careful harvesting of a thin piece of skin, typically measuring between 0.006 to 0.008 inches in thickness. This harvested skin is then cut into smaller strips, each measuring approximately 2 cm by 3 cm. These strips are placed into a specialized SCSA device, where they undergo enzymatic incubation for a period of 15 to 20 minutes. This enzymatic processing is critical as it softens the skin tissue, allowing for easier separation of the skin cells.

After the incubation period, the physician evaluates the skin to determine if the enzymatic treatment has sufficiently broken down the tissue. If the skin is not adequately processed, it is returned to the device for additional enzymatic treatment. Once the skin cells can be easily separated, the physician rinses the tissue with a buffer solution to prepare it for the next step. The skin is then placed dermal side down on a mechanical scraping tray, where the physician employs vigorous scraping techniques from various orientations. This vigorous scraping is essential to ensure the complete removal of the skin cells from the tissue.

Following the scraping, the physician rinses the scraped material to capture all disaggregated cells. The final step involves using a syringe to draw up the prepared SCSA cells from the collection tray. These cells are then filtered through a cell strainer to ensure a clean and viable cell suspension, ready for application to the wound site. It is important to note that CPT® 15014 is reported for each additional 25 square centimeters of harvested skin or any part thereof, in addition to the primary procedure code for the first 25 square centimeters or less, which is CPT® 15013.

3. Post-Procedure

Post-procedure care following the preparation of a skin cell suspension autograft involves monitoring the wound site for signs of healing and potential complications. The physician may provide specific instructions regarding wound care, including keeping the area clean and protected. Patients are typically advised on how to manage any discomfort and when to seek further medical attention if complications arise. The expected recovery time may vary depending on the size and location of the wound, as well as the patient's overall health. Regular follow-up appointments may be scheduled to assess the healing process and determine if additional treatments are necessary.
