Official Description

Open treatment of phalangeal shaft fracture, proximal or middle phalanx, finger or thumb, includes internal fixation, when performed, each

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 26735 refers to the open treatment of a fracture located in the shaft of the proximal or middle phalanx of a finger or thumb. This procedure is specifically designed for cases where the fracture requires surgical intervention to ensure proper healing and alignment. The term "open treatment" indicates that the procedure involves making an incision to access the fractured bone directly, allowing for a thorough examination and repair of the injury. During the procedure, the surgeon will retract the overlying tissue to expose the fracture site, elevate the periosteum, and meticulously clear any debris that may impede healing. Once the fracture is identified, the surgeon will perform a reduction, which is the process of realigning the fractured bone fragments to their normal anatomical position. Internal fixation may be utilized to stabilize the fracture, employing devices such as pins, small screws, or a plate and screw system to maintain the alignment of the bone fragments during the healing process. It is important to note that if multiple fractures in the proximal or middle phalanx shafts are treated during the same surgical session, each fracture should be reported using CPT® Code 26735, ensuring accurate coding for each treated bone.

1. Indications

The open treatment of phalangeal shaft fractures, as described by CPT® Code 26735, is indicated for specific conditions and symptoms that necessitate surgical intervention. These indications include:

  • Fracture of the proximal phalanx - This involves a break in the bone located in the first segment of the finger or thumb, which may result from trauma or injury.
  • Fracture of the middle phalanx - This pertains to a fracture occurring in the second segment of the finger, often requiring surgical correction to restore function.
  • Displacement of fracture fragments - When the broken ends of the bone are not aligned properly, surgical treatment is necessary to realign and stabilize the fracture.
  • Inability to achieve adequate alignment through closed methods - If non-surgical methods, such as casting or splinting, are insufficient to stabilize the fracture, open treatment becomes necessary.

2. Procedure

The procedure for the open treatment of phalangeal shaft fractures involves several critical steps, which are outlined as follows:

  • Step 1: Incision - The surgeon begins by making a precise incision over the fractured phalanx. This incision allows for direct access to the bone and surrounding tissues, facilitating the subsequent steps of the procedure.
  • Step 2: Tissue Retraction - Once the incision is made, the overlying tissue is carefully retracted to expose the fracture site. This step is crucial for providing a clear view of the bone and ensuring that the surgical field is unobstructed.
  • Step 3: Elevation of the Periosteum - The periosteum, a dense layer of connective tissue surrounding the bone, is elevated to gain better access to the fracture. This elevation is essential for proper visualization and manipulation of the fracture fragments.
  • Step 4: Identification and Cleaning of the Fracture - The surgeon identifies the fracture and clears the site of any debris or foreign material that may hinder healing. This cleaning process is vital for reducing the risk of infection and promoting optimal recovery.
  • Step 5: Fracture Reduction - The next step involves the reduction of the fracture, where the surgeon realigns the fractured bone fragments to their normal anatomical position. Achieving proper alignment is critical for the healing process.
  • Step 6: Internal Fixation - If deemed necessary, internal fixation is applied to stabilize the fracture. This may involve the use of pins, small screws, or a plate and screw device, which are selected based on the specific characteristics of the fracture.

3. Post-Procedure

After the open treatment procedure is completed, post-operative care is essential for ensuring proper healing and recovery. Patients are typically monitored for any signs of complications, such as infection or improper alignment. Pain management strategies are implemented to alleviate discomfort during the recovery period. The surgical site may be bandaged, and instructions regarding wound care will be provided. Patients are often advised on activity restrictions to prevent undue stress on the healing bone. Follow-up appointments are scheduled to assess the healing process and to determine when rehabilitation or physical therapy may be initiated to restore function and strength to the affected finger or thumb.

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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
55 Postoperative management only: when 1 physician or other qualified health care professional performed the postoperative management and another performed the surgical procedure, the postoperative component may be identified by adding modifier 55 to the usual procedure number.
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.
74 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure after administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may terminate a surgical or diagnostic procedure after the administration of anesthesia (local, regional block(s), general) or after the procedure was started (incision made, intubation started, scope inserted, etc). under these circumstances, the procedure started but terminated can be reported by its usual procedure number and the addition of modifier 74. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
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).
