The procedure described by CPT® Code 28106 involves the excision or curettage of a bone cyst or benign tumor located in the tarsal or metatarsal bones, excluding the talus or calcaneus. A bone cyst is defined as a fluid-filled space within the bone, which can be benign in nature. Among the various types of bone cysts, the unicameral or simple bone cyst is the most common, while the aneurysmal bone cyst, characterized by vascular tissue surrounding a blood-filled cystic lesion, is less frequently encountered. Additionally, there are several types of benign bone tumors, including giant cell tumors, chondromyxoid fibromas, and enchondromas, which may also necessitate surgical intervention. The procedure begins with an incision made over the lesion site, followed by dissection of the soft tissues to expose the lesion. If a cystic lesion is identified, a window is created in the bone to access the cyst, allowing for aspiration of the fluid for laboratory analysis. The lining of the cystic cavity is then removed using a curette. In cases where a benign tumor is present, the lesion is excised along with a margin of healthy bone. Following the excision or curettage, the procedure involves obtaining an autograft, typically from the iliac crest, which is then packed into the defect created in the tarsal or metatarsal bone. This comprehensive approach ensures the removal of the lesion while promoting healing through the use of the patient's own bone tissue.

The procedure described by CPT® Code 28106 is indicated for the treatment of specific conditions affecting the tarsal or metatarsal bones, particularly when a bone cyst or benign tumor is present. The following conditions may warrant this surgical intervention:
The procedure for CPT® Code 28106 involves several critical steps to ensure the effective removal of the bone cyst or benign tumor:
Post-procedure care following the excision or curettage of a bone cyst or benign tumor involves monitoring the surgical site for signs of infection and ensuring proper healing. Patients may be advised to limit weight-bearing activities on the affected foot to facilitate recovery. Follow-up appointments are essential to assess the healing process and to ensure that the graft integrates properly with the surrounding bone. Pain management strategies may also be implemented to address any discomfort during the recovery period.

| 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). | 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. | 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.) | 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 | 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) | T5 | Right foot, great toe | TA | Left foot, great toe | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure |
