An osteotomy of the ulna, as described by CPT® Code 25360, is a surgical procedure aimed at correcting a deformity or realigning the ulna bone. This procedure may be performed on the ulna alone or in conjunction with the radius, depending on the specific deformity being addressed. The choice of the osteotomy type and its location is determined by the nature and site of the deformity. Various techniques can be employed during the osteotomy, including transverse, wedge, sliding, right or left angle, V-osteotomy, and Z-osteotomy. Prior to the surgical intervention, the physician utilizes radiographic studies to accurately identify the precise locations for the bone cuts necessary to achieve the desired alignment. During the procedure, an incision is made in the forearm at the site of the deformity, allowing for the dissection of soft tissues to expose the ulna. The periosteum, a layer of connective tissue surrounding the bone, is elevated to facilitate access. The bone is then cut using surgical instruments such as a drill, saw, or osteotome, following the predetermined configuration. If necessary, bone grafts may be placed between the cut segments to promote healing and stability. To ensure that the bone edges remain properly aligned, various internal fixation devices, such as pins, screws, or plates, may be applied. Alternatively, an external fixation device can be utilized if indicated. This procedure is critical for restoring proper function and alignment of the ulna, ultimately improving the patient's quality of life.

The osteotomy of the ulna, coded as CPT® 25360, is indicated for various conditions that necessitate the correction of bone deformities or misalignments. The following are specific indications for performing this procedure:
The procedure for an osteotomy of the ulna involves several critical steps, each designed to ensure the successful correction of the deformity. The following outlines the procedural steps involved:
After the osteotomy of the ulna is completed, the patient will require specific post-procedure care to ensure optimal recovery. This may include monitoring for any signs of complications, such as infection or improper healing. Patients are typically advised to limit movement of the affected arm to allow for proper healing of the bone. Follow-up appointments will be necessary to assess the healing process and to remove any internal fixation devices if used. Rehabilitation exercises may be recommended to restore function and strength to the forearm and wrist as healing progresses. The overall recovery time can vary based on the individual patient's condition and the extent of the procedure performed.

| 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). | 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.) | 80 | Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s). | 82 | Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s). | AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | CR | Catastrophe/disaster related | GC | This service has been performed in part by a resident under the direction of a teaching physician | 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) | 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 |
