The procedure described by CPT® Code 28108 involves the excision or curettage of a bone cyst or benign tumor located in the phalanges of the foot. A bone cyst is defined as a fluid-filled space within the bone, which can vary in type and presentation. The unicameral or simple bone cyst is the most common form, characterized as a benign lesion that typically does not pose significant health risks. In contrast, an aneurysmal bone cyst is less common and is composed of vascular tissue that encases a blood-filled cystic lesion. Additionally, there are various types of benign bone tumors that may be encountered, including giant cell tumors, chondromyxoid fibromas, and enchondromas. During the procedure, an incision is made over the affected area of the proximal, middle, or distal phalanx of one of the toes. The soft tissues surrounding the lesion are carefully dissected to expose the underlying bone. If a cystic lesion is identified, the surgeon incises the bone to create a window, allowing access to the cyst. The fluid within the cyst is aspirated and sent for laboratory analysis, which is reportable separately. Following this, a curette is utilized to thoroughly remove the lining of the cystic cavity through the created bone window. In cases where a benign tumor is present, the approach may differ slightly; the lesion is exposed similarly, and the physician excises the tumor along with a margin of healthy bone to ensure complete removal. This procedure is essential for addressing bone cysts and benign tumors in the foot, promoting recovery and alleviating any associated symptoms.

The procedure described by CPT® Code 28108 is indicated for the treatment of specific conditions affecting the phalanges of the foot. These indications include:
The procedure for excision or curettage of a bone cyst or benign tumor in the phalanges of the foot involves several key steps:
After the excision or curettage procedure, post-operative care is essential for optimal recovery. Patients may be advised to rest and limit weight-bearing activities on the affected foot to promote healing. Pain management may be necessary, and the surgical site should be monitored for signs of infection or complications. Follow-up appointments will be scheduled to assess healing and to discuss any further treatment if required. The recovery period may vary depending on the extent of the procedure and the individual patient's health status.

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. | 76 | Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service. | 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). | AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | CC | Procedure code change (use 'cc' when the procedure code submitted was changed either for administrative reasons or because an incorrect code was filed) | F1 | Left hand, second digit | F7 | Right hand, third digit | F9 | Right hand, fifth digit | 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) | SG | Ambulatory surgical center (asc) facility service | T1 | Left foot, second digit | T2 | Left foot, third digit | T3 | Left foot, fourth digit | T4 | Left foot, fifth digit | T5 | Right foot, great toe | T6 | Right foot, second digit | T7 | Right foot, third digit | T8 | Right foot, fourth digit | T9 | Right foot, fifth digit | TA | Left foot, great toe | X4 | Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period | 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 |
