CPT® Code 15774

Add-On Code

Grafting of autologous fat harvested by liposuction technique to face, eyelids, mouth, neck, ears, orbits, genitalia, hands, and/or feet; each additional 25 cc injectate, or part thereof (List separately in addition to code for primary procedure)

Autologous fat grafting, commonly referred to as fat transfer, is a surgical procedure that involves the harvesting of adipose tissue from one area of the patient's body, typically through a liposuction technique, and then injecting it into another area to restore volume or improve contour. This procedure can be performed for both reconstructive and aesthetic purposes, addressing issues such as volume loss or contour deformities that may arise from various factors including disease, trauma, tumor removal, congenital defects, or the natural aging process. The process begins with the careful harvesting of fat, which is then processed through specific techniques to prepare it for injection. During the procedure, small incisions are made in the skin, corresponding to the size of the injection cannula(s). These cannulas are inserted through the incisions and guided to the targeted areas where the fat is to be injected. As the cannula is withdrawn, the autologous fat is injected in small amounts, distributed in a fanned-out pattern at different depths. This technique helps to minimize interstitial pressure and prevents overcrowding of the transplanted adipocytes, which is crucial for the success of the graft. The CPT® Code 15773 is used to report the initial autologous fat grafting procedure involving 25 cc or less of injectate, while CPT® Code 15774 is designated for each additional 25 cc or part thereof, allowing for precise billing and documentation of the procedure performed.
