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 and its subsequent injection into another area to restore volume or improve contour. This technique is utilized for both reconstructive and aesthetic purposes, addressing issues such as volume loss or deformities that may arise from various causes, including disease, trauma, tumor removal, congenital defects, and the natural aging process. The procedure begins with the collection of fat through liposuction, which is a minimally invasive technique that uses small incisions to access the fat deposits. The harvested fat is then processed to prepare it for injection. During the injection phase, small cannulas are used to deliver the fat into the targeted areas, such as the face, eyelids, mouth, neck, ears, orbits, genitalia, hands, and feet. The injection technique is critical, as the fat is distributed in small amounts at different depths to minimize pressure and ensure the survival of the transplanted adipocytes. The specific code for this procedure, CPT® Code 15773, is applicable when 25 cc or less of the injectate is used. For larger volumes, additional coding is required, as indicated by CPT® Code 15774, which accounts for each additional 25 cc or part thereof.

Autologous fat grafting is indicated for a variety of conditions and purposes, including:
The autologous fat grafting procedure involves several key steps, which are detailed as follows:
Following the autologous fat grafting procedure, patients may experience some swelling, bruising, and discomfort in the treated areas. It is important for patients to follow post-operative care instructions provided by their healthcare provider, which may include recommendations for pain management, activity restrictions, and follow-up appointments to monitor healing. The expected recovery time can vary depending on the extent of the procedure and the individual patient's healing response. Patients should be informed about the potential for some of the injected fat to be absorbed by the body over time, which may necessitate additional treatments to achieve the desired results.

| GC | This service has been performed in part by a resident under the direction of a teaching physician | 22 | Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service. | 51 | Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 52 | Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use). | 58 | Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78. | 59 | Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25. | 78 | Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.) | 79 | Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.) | AQ | Physician providing a service in an unlisted health professional shortage area (hpsa) | AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | F5 | Right hand, thumb | FA | Left hand, thumb | GA | Waiver of liability statement issued as required by payer policy, individual case | KX | Requirements specified in the medical policy have been met | LT | Left side (used to identify procedures performed on the left side of the body) | RT | Right side (used to identify procedures performed on the right side of the body) | SG | Ambulatory surgical center (asc) facility service | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
