Official Description

Arthrodesis, with extensor hallucis longus transfer to first metatarsal neck, great toe, interphalangeal joint (eg, Jones type procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 28760 refers to an arthrodesis involving the great toe, specifically the interphalangeal joint. Arthrodesis is a surgical procedure that fuses two bones together, in this case, the proximal and distal phalanx of the great toe, to eliminate movement at the joint. This is often indicated in cases where there is severe joint pain or instability, typically due to conditions such as arthritis or injury. The procedure involves a meticulous surgical approach, beginning with an incision made over the lateral aspect of the interphalangeal joint. Surgeons must take care to protect surrounding nerves and blood vessels during this process. Once the joint is accessed, the articular cartilage is excised, which is the smooth tissue that covers the ends of bones in a joint, allowing for smooth movement. The next step involves scaling the articular surfaces of the proximal and distal phalanx using an osteotome, a specialized surgical instrument. This prepares the bone surfaces for fusion by exposing cancellous bone, which is the spongy bone that facilitates healing and integration. A key component of this procedure is the transfer of the extensor hallucis longus tendon to the first metatarsal neck. This tendon is responsible for extending the big toe and its transfer helps to stabilize the joint post-fusion. To ensure stability during the healing process, internal fixation devices such as pins, screws, staples, or a small plate are utilized to hold the bones in place across the joint. Finally, the incision is closed, and a bulky dressing is applied to protect the surgical site and support the healing process. This comprehensive approach aims to alleviate pain and restore function to the great toe, enhancing the patient's overall mobility and quality of life.

1. Indications

The procedure described by CPT® Code 28760 is indicated for specific conditions affecting the great toe, particularly the interphalangeal joint. The following are the explicitly provided indications for performing this procedure:

  • Severe Joint Pain - This procedure is often indicated in patients experiencing significant pain in the great toe joint, which may be due to degenerative joint disease or other arthritic conditions.
  • Joint Instability - Arthrodesis may be necessary when there is instability in the joint, which can lead to functional impairment and difficulty in ambulation.
  • Previous Injury - Patients who have sustained injuries to the great toe that have resulted in chronic pain or joint dysfunction may also be candidates for this surgical intervention.

2. Procedure

The procedure for CPT® Code 28760 involves several critical steps to ensure successful arthrodesis of the great toe. Each step is detailed as follows:

  • Step 1: Incision - The surgical process begins with the creation of an incision over the lateral aspect of the interphalangeal joint of the great toe. Surgeons must exercise caution to protect the surrounding nerves and blood vessels during this initial step to prevent complications.
  • Step 2: Joint Exposure - After the incision is made, the joint is carefully exposed. This involves the removal of any overlying tissue to gain access to the articular surfaces of the joint.
  • Step 3: Cartilage Excision - The next step involves the excision of the articular cartilage from the joint surfaces. This is crucial as it prepares the bones for fusion by removing the smooth surfaces that allow for joint movement.
  • Step 4: Bone Preparation - Using an osteotome, the articular surfaces of the proximal and distal phalanx are scaled. This action exposes the cancellous bone, which is essential for the fusion process as it promotes healing and integration of the bones.
  • Step 5: Tendon Transfer - The extensor hallucis longus tendon is then detached from its original attachment and transferred to the first metatarsal neck. This step is vital for providing stability to the joint post-fusion.
  • Step 6: Internal Fixation - To stabilize the joint during the healing process, internal fixation devices such as pins, screws, staples, or a small plate are placed through the bones and across the joint. This ensures that the bones remain in the correct position as they heal together.
  • Step 7: Closure - Finally, the incision is closed using appropriate suturing techniques, and a bulky dressing is applied to protect the surgical site and support the healing process.

3. Post-Procedure

Post-procedure care following an arthrodesis of the great toe is essential for optimal recovery. Patients can expect to have a bulky dressing applied to the surgical site, which should remain intact until the first follow-up appointment. It is important to monitor the incision for any signs of infection or complications. Patients may be advised to limit weight-bearing activities on the affected foot for a specified period to allow for proper healing. Rehabilitation may include physical therapy to restore mobility and strength in the toe and foot once the initial healing phase has passed. Follow-up visits will be necessary to assess the healing process and determine when it is safe to resume normal activities.

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.
