Official Description

Excision or curettage of bone cyst or benign tumor of carpal bones;

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 25130 involves the excision or curettage of a bone cyst or benign tumor located within the carpal bones, which are the eight small bones that form the wrist joint. A bone cyst is characterized as a fluid-filled space within the bone, and it can manifest in various forms. One common type is the unicameral or simple bone cyst, which is a benign lesion that typically does not pose a significant health risk. Another type, the aneurysmal bone cyst, is less common and is composed of vascular tissue that surrounds a blood-filled cystic lesion. Additionally, there are several types of benign bone tumors that may be encountered, including giant cell tumors, chondromyxoid fibromas, and enchondromas. During the procedure associated with CPT® Code 25130, the physician initiates the process by making an incision in the skin directly over the lesion located in the carpal bone. Following this, the soft tissues are carefully dissected to expose the lesion. If a cystic lesion is identified, the physician incises the bone to create a window, allowing access to the cyst. The fluid within the cyst is then aspirated and sent to a laboratory for analysis, which is reportable separately. A curette is subsequently inserted through the bone window to completely remove the lining of the cystic cavity via curettage. In cases where a benign tumor is present, the procedure may involve excision instead of curettage. The lesion is exposed in a similar manner, and the physician excises the benign lesion along with a margin of surrounding healthy bone to ensure complete removal. This procedure is critical for addressing bone cysts and benign tumors in the wrist, facilitating recovery and preventing further complications.

1. Indications

The procedure described by CPT® Code 25130 is indicated for the removal of bone cysts or benign tumors located in the carpal bones. The following conditions may warrant this procedure:

  • Bone Cyst: A fluid-filled space within the bone that may require intervention if symptomatic or causing structural issues.
  • Unicameral Bone Cyst: A common type of benign lesion that may necessitate excision or curettage if it leads to pain or functional impairment.
  • Aneurysmal Bone Cyst: A less common, vascularized cyst that may require surgical intervention due to its potential for expansion and associated symptoms.
  • Benign Bone Tumors: Various types of benign tumors, such as giant cell tumors, chondromyxoid fibromas, and enchondromas, which may require excision to alleviate symptoms or prevent complications.

2. Procedure

The procedure for CPT® Code 25130 involves several critical steps to ensure the effective removal of the bone cyst or benign tumor:

  • Step 1: The physician begins by making an incision in the skin directly over the site of the lesion located in the carpal bone. This incision allows for direct access to the underlying structures.
  • Step 2: Following the incision, the physician carefully dissects the soft tissues to expose the lesion. This step is crucial for visualizing the cyst or tumor and determining the appropriate course of action.
  • Step 3: If a cystic lesion is present, the physician incises the bone to create a bone window. This window provides access to the cyst, allowing for further intervention.
  • Step 4: The fluid within the cyst is aspirated and sent to the laboratory for analysis. This step is important for diagnostic purposes and may provide additional information regarding the nature of the lesion.
  • Step 5: A curette is then inserted through the bone window to remove the lining of the cystic cavity completely. This process, known as curettage, ensures that the cyst is adequately addressed.
  • Step 6: In cases where a benign tumor is present, the physician may opt for excision instead of curettage. The lesion is exposed as previously described, and the physician excises the benign lesion along with a margin of surrounding healthy bone to ensure complete removal.

3. Post-Procedure

After the procedure associated with CPT® Code 25130, the patient may require specific post-operative care to ensure proper healing and recovery. This may include monitoring for any signs of infection at the incision site, managing pain with prescribed medications, and following up with the physician for any necessary imaging or assessments. The expected recovery time can vary depending on the extent of the procedure and the individual patient's health status. Patients are typically advised to limit activities that may stress the wrist during the initial healing phase, and rehabilitation exercises may be recommended to restore function and strength in the wrist joint.

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.)
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).
