Official Description

Excision or curettage of bone cyst or benign tumor of proximal, middle, or distal phalanx of finger;

Common Language Description

The CPT® Code 26210 refers to the excision or curettage of a bone cyst or benign tumor located in the proximal, middle, or distal phalanx of a finger. A bone cyst is defined as a fluid-filled space within the bone, which can vary in type. The most common type is the unicameral or simple bone cyst, recognized as a benign lesion. Another type, though less common, is the aneurysmal bone cyst, characterized by vascular tissue surrounding a blood-filled cystic lesion. Additionally, there are various benign bone tumors, including giant cell tumors, chondromyxoid fibromas, and enchondromas. The procedure involves making an incision over the lesion site in the phalanx of a finger, followed by dissection of the soft tissues to expose the lesion. If a cystic lesion is identified, the bone is incised to create a window, allowing access to the cyst for fluid aspiration, which is then sent for laboratory analysis. The curettage process involves using a curette to remove the lining of the cystic cavity completely. In cases where benign tumors are present, the procedure may involve excising the tumor along with a margin of healthy bone to ensure complete removal. This procedure is critical for addressing bone cysts and benign tumors in the fingers, facilitating proper treatment and recovery.

1. Indications

The procedure described by CPT® Code 26210 is indicated for the treatment of specific conditions affecting the phalanx of the finger. These include:

  • Bone Cyst: A fluid-filled space within the bone that may require intervention due to size, symptoms, or risk of complications.
  • Benign Tumor: Non-cancerous growths such as giant cell tumors, chondromyxoid fibromas, or enchondromas that may cause pain, discomfort, or functional impairment.

2. Procedure

The procedure for CPT® Code 26210 involves several critical steps to ensure the effective excision or curettage of the bone cyst or benign tumor:

  • Step 1: An incision is made in the skin directly over the site of the lesion located in the proximal, middle, or distal phalanx of the finger. This initial step is crucial for accessing the underlying structures.
  • Step 2: The soft tissues surrounding the lesion are carefully dissected to expose the lesion fully. This dissection must be performed with precision to avoid damage to adjacent structures.
  • Step 3: If a cystic lesion is present, the bone is incised, and a bone window is created to access the cyst. This allows for the aspiration of the fluid within the cyst, which is then sent to the laboratory for analysis.
  • Step 4: A curette is inserted through the bone window to remove the lining of the cystic cavity completely. This step is essential for ensuring that the cyst does not recur.
  • Step 5: In cases where a benign tumor is present, the lesion is excised along with a margin of surrounding healthy bone. This excision is critical to ensure complete removal of the tumor and to minimize the risk of recurrence.

3. Post-Procedure

Post-procedure care following the excision or curettage of a bone cyst or benign tumor includes monitoring for any signs of infection, managing pain, and ensuring proper wound healing. Patients may be advised to limit movement of the affected finger to promote recovery and prevent complications. Follow-up appointments are typically scheduled to assess healing and to determine if any further treatment is necessary.

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.

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.
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).
