Official Description

Open treatment of ulnar fracture, proximal end (eg, olecranon or coronoid process[es]), includes internal fixation, when performed

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Open treatment of an ulnar fracture at the proximal end involves a surgical procedure aimed at correcting a fracture in the ulna, which is one of the two long bones in the forearm, located on the side opposite the thumb. This procedure specifically addresses fractures that occur at the proximal end of the ulna, which includes the olecranon and coronoid processes. The olecranon is the prominent bony structure at the back of the elbow, while the coronoid process is a smaller projection located at the front of the elbow joint. These structures are critical for the stability and function of the elbow joint, as they articulate with the humerus, the upper arm bone. During the procedure, an incision is made over the elbow to access the fracture site. The surgeon carefully clears any debris from the fracture area to ensure a clean working environment. The fractured bone fragments are then realigned, or reduced, into their proper anatomical position. To maintain this alignment, the fragments are secured using various internal fixation methods, which may include the use of wires, pins, screws, or plates. After fixation, the elbow is immobilized with a sling or splint to promote healing and prevent movement that could disrupt the repair. This comprehensive approach ensures that the fracture is treated effectively, allowing for optimal recovery and restoration of function in the elbow joint.

1. Indications

The open treatment of ulnar fractures at the proximal end is indicated for specific conditions and symptoms that necessitate surgical intervention. These include:

  • Fracture of the Olecranon A fracture involving the olecranon, which is the bony prominence at the back of the elbow, often requires surgical treatment to restore proper function and stability to the elbow joint.
  • Fracture of the Coronoid Process A fracture of the coronoid process, the anterior projection of the ulna, may also necessitate open treatment to ensure proper alignment and healing.
  • Displaced Fractures Fractures that are displaced, meaning the bone fragments are not aligned properly, typically require surgical intervention to realign and stabilize the fracture.
  • Inability to Heal with Conservative Treatment Cases where conservative treatment methods, such as immobilization or casting, have failed to achieve adequate healing may warrant surgical intervention.

2. Procedure

The procedure for open treatment of a proximal ulnar fracture involves several critical steps to ensure effective repair and stabilization of the fracture. These steps include:

  • Incision The surgeon begins by making an incision over the elbow to gain access to the fracture site. This incision is strategically placed to minimize damage to surrounding tissues while providing adequate visibility and access to the bone.
  • Clearing the Fracture Site Once the incision is made, the surgeon carefully clears the fracture site of any debris, such as bone fragments or soft tissue, to create a clean environment for the repair. This step is crucial for preventing infection and ensuring proper healing.
  • Reduction of the Fracture After the site is cleared, the surgeon proceeds to reduce the fracture, which involves realigning the bone fragments into their correct anatomical position. This step is essential for restoring the normal function of the elbow joint.
  • Internal Fixation To maintain the alignment of the bone fragments, the surgeon employs internal fixation techniques. This may involve the use of sutures, wires, pins, screws, or a plate that is placed under the ulna and around the tip of the elbow, secured with screws. The choice of fixation method depends on the specific nature of the fracture and the surgeon's preference.
  • Immobilization Following the fixation, the elbow is immobilized using a sling or splint. This immobilization is critical for protecting the repair and allowing the fracture to heal properly.

3. Post-Procedure

After the open treatment of the ulnar fracture, post-procedure care is essential for optimal recovery. Patients are typically advised to keep the affected arm elevated to reduce swelling and to follow specific instructions regarding the use of the sling or splint. Pain management may be necessary, and the healthcare provider may prescribe medications to alleviate discomfort. Follow-up appointments are crucial to monitor the healing process, assess the stability of the fixation, and determine when it is safe to begin rehabilitation exercises. Physical therapy may be recommended to restore range of motion and strength in the elbow joint as healing progresses. Patients should be informed about signs of complications, such as increased pain, swelling, or signs of infection, and instructed to seek medical attention if these occur.

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).
GC This service has been performed in part by a resident under the direction of a teaching physician
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.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
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.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
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).
