The CPT® Code 28104 refers to 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 cavity within the bone, which can vary in type and presentation. The most common form is the unicameral or simple bone cyst, recognized as a benign lesion that typically does not pose significant health risks. Another type, the aneurysmal bone cyst, is characterized by a vascular structure surrounding a blood-filled cystic lesion, which may require more complex management. Additionally, benign bone tumors such as giant cell tumors, chondromyxoid fibromas, and enchondromas can also necessitate surgical intervention. The procedure associated with CPT® Code 28104 involves making an incision over the affected area of the tarsal or metatarsal bone, followed by careful dissection of the surrounding soft tissues to expose the lesion. If a cystic lesion is identified, the surgeon creates a window in the bone to access the cyst, aspirating its fluid for laboratory analysis. The curettage process involves using a curette to meticulously remove the lining of the cystic cavity. In cases where benign tumors are present, the excision technique is employed, which entails removing the tumor along with a margin of healthy bone to ensure complete removal and minimize the risk of recurrence.

The procedure described by CPT® Code 28104 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 associated with CPT® Code 28104 involves several critical steps to ensure the effective excision or curettage of the bone cyst or benign tumor. The following procedural steps are outlined:
After the completion of the procedure associated with CPT® Code 28104, post-operative care is essential for optimal recovery. Patients are typically monitored for any signs of complications, such as infection or excessive bleeding. Pain management strategies may be implemented to address discomfort following the surgery. The surgical site will require appropriate dressing and care to promote healing. Patients may be advised to limit weight-bearing activities on the affected foot for a specified period to allow for proper recovery. Follow-up appointments are crucial to assess healing and determine if any further interventions are necessary. Additionally, any laboratory results from the aspirated fluid will be reviewed to guide further management if needed.

| 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) | 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. | 50 | Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 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). | 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). | AG | Primary physician | 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) | F9 | Right hand, fifth digit | GC | This service has been performed in part by a resident under the direction of a teaching physician | GW | Service not related to the hospice patient's terminal condition | 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 | 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 |
