Official Description

Open treatment of posterior pelvic bone fracture and/or dislocation, for fracture patterns that disrupt the pelvic ring, unilateral, includes internal fixation, when performed (includes ipsilateral ilium, sacroiliac joint and/or sacrum)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 27218 refers to the open treatment of posterior pelvic bone fractures and/or dislocations, specifically for fracture patterns that disrupt the pelvic ring on a unilateral basis. This procedure includes internal fixation when performed, which may involve the ipsilateral ilium, sacroiliac joint, and/or sacrum. Posterior pelvic ring fractures typically involve injuries to the ilium and/or sacrum, and they can also include dislocation or fracture dislocation injuries affecting the sacroiliac joints. To accurately assess the extent of the injury to the posterior pelvic ring, a radiographic study of the pelvis is conducted, which is separately reportable. The surgical approach involves making an incision to expose the fracture or dislocation site, followed by the removal of any debris to facilitate a clear view of the injury. Once the site is adequately prepared, the fracture or dislocation is reduced to restore anatomical alignment. After achieving proper reduction, the bone is prepared for the application of an internal fixation device, which may consist of screws, a transiliac sacral bar (commonly known as a Harrington rod), or a plate and screw fixation device. The procedure is completed by verifying the alignment of the fracture fragments through radiographic imaging, followed by the irrigation and closure of the wound.

1. Indications

The procedure described by CPT® Code 27218 is indicated for specific conditions related to posterior pelvic bone fractures and/or dislocations. These indications include:

  • Posterior Pelvic Ring Fractures These fractures involve the ilium and/or sacrum, which are critical components of the pelvic structure.
  • Dislocation Injuries This includes dislocation or fracture dislocation injuries that affect the sacroiliac joints, which are essential for pelvic stability.
  • Fracture Patterns Disrupting the Pelvic Ring The procedure is specifically indicated for fracture patterns that disrupt the integrity of the pelvic ring, necessitating surgical intervention for proper alignment and stabilization.

2. Procedure

The open treatment of posterior pelvic bone fractures and/or dislocations involves several critical procedural steps, which are detailed as follows:

  • Step 1: Radiographic Assessment A separately reportable radiographic study of the pelvis is performed to evaluate the extent of the posterior pelvic ring injury. This imaging is crucial for planning the surgical approach and understanding the fracture pattern.
  • Step 2: Incision and Exposure An incision is made to access the fracture or dislocation site. This step is essential to provide a clear view of the injury, allowing for effective treatment.
  • Step 3: Debris Clearance The surgical site is cleared of any debris, which is necessary to ensure that the area is clean and suitable for reduction and fixation.
  • Step 4: Reduction of Fracture/Dislocation Once the site is prepared, the fracture or dislocation is reduced to restore anatomical alignment. Achieving proper reduction is critical for the success of the procedure.
  • Step 5: Preparation for Internal Fixation After anatomical reduction, the bone is prepared for the application of an internal fixation device. This preparation may involve drilling to create a suitable pathway for screws or other fixation devices.
  • Step 6: Application of Fixation Devices Depending on the chosen method, screws may be placed, or a transiliac sacral bar (Harrington rod) or plate and screw fixation device may be utilized. If screws are used, a temporary pin fixation device is applied to maintain alignment while verifying the position radiographically.
  • Step 7: Verification of Alignment The alignment of the fracture fragments is confirmed through radiographic imaging, ensuring that the reduction is stable and accurate.
  • Step 8: Wound Closure After confirming proper alignment and fixation, the surgical site is irrigated to prevent infection, and the incision is closed to complete the procedure.

3. Post-Procedure

Post-procedure care following the open treatment of posterior pelvic bone fractures and/or dislocations includes monitoring for any signs of complications, such as infection or improper healing. Patients may require pain management and physical therapy to aid in recovery. Follow-up appointments are essential to assess the healing process and to conduct any necessary imaging studies to ensure that the internal fixation devices are functioning as intended. The expected recovery time may vary based on the severity of the injury and the individual patient's health status.

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.
