Official Description

Excision or curettage of bone cyst or benign tumor, talus or calcaneus; with iliac or other autograft (includes obtaining graft)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 28102 refers to the surgical procedure involving the excision or curettage of a bone cyst or benign tumor located in the talus or calcaneus, which are bones in the foot. This procedure is performed with the use of an iliac or other autograft, which includes the process of obtaining the graft. A bone cyst is defined as a fluid-filled space within the bone, and it can be classified into various types. The unicameral or simple bone cyst is a common benign lesion, while the aneurysmal bone cyst is characterized by vascular tissue surrounding a blood-filled cystic lesion. Additionally, benign bone tumors can include giant cell tumors, chondromyxoid fibromas, and enchondromas. 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 fluid aspiration and laboratory analysis. The lining of the cystic cavity is then removed through curettage, or the benign tumor may be excised along with a margin of healthy bone. Following the excision or curettage, healthy bone is harvested from a separate site, typically the iliac crest, and is then packed into the defect created in the talus or calcaneus. This procedure is essential for addressing bone cysts and benign tumors, ensuring proper healing and structural integrity of the affected bone.

1. Indications

The procedure described by CPT® Code 28102 is indicated for the treatment of specific conditions related to bone cysts and benign tumors in the talus or calcaneus. The following are the primary indications for performing this procedure:

  • Bone Cysts A fluid-filled space within the bone that may require excision or curettage to alleviate symptoms or prevent complications.
  • Benign Bone Tumors Non-cancerous growths such as giant cell tumors, chondromyxoid fibromas, and enchondromas that necessitate removal to maintain bone health and function.

2. Procedure

The procedure involves several critical steps to ensure the effective excision or curettage of the lesion. Each step is detailed as follows:

  • Step 1: Incision and Exposure An incision is made in the skin over the site of the lesion located in the talus or calcaneus. The surgeon carefully dissects the soft tissues to expose the underlying lesion, ensuring minimal damage to surrounding structures.
  • Step 2: Accessing the Cystic Lesion If a cystic lesion is present, the surgeon incises the bone to create a window that allows access to the cyst. The fluid within the cyst is aspirated and sent to the laboratory for analysis, which may be necessary for further diagnostic purposes.
  • Step 3: Curettage or Excision A curette is inserted through the bone window to remove the lining of the cystic cavity completely. Alternatively, if a benign tumor is present, the surgeon excises the tumor along with a margin of healthy bone to ensure complete removal and reduce the risk of recurrence.
  • Step 4: Grafting After the lesion has been adequately treated, the surgeon obtains healthy bone from a separate site, such as the iliac crest. This autograft is then packed into the defect created in the talus or calcaneus, promoting healing and structural support.

3. Post-Procedure

Post-procedure care is essential for optimal recovery following the excision or curettage of a bone cyst or benign tumor. Patients are typically monitored for any signs of complications, such as infection or excessive bleeding. Pain management strategies are implemented to ensure patient comfort during the recovery phase. Rehabilitation may be necessary to restore function and strength to the affected area, and follow-up appointments are scheduled to assess healing and the success of the graft. It is crucial for patients to adhere to post-operative instructions provided by their healthcare provider to facilitate a smooth recovery process.

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).
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.)
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).
