Official Description

Open treatment of acetabular fracture(s) involving anterior or posterior (one) column, or a fracture running transversely across the acetabulum, with internal fixation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 27227 pertains to the open treatment of acetabular fractures, which are injuries to the acetabulum, the socket of the hip joint where the femur (thigh bone) fits. The acetabulum is a complex structure made up of several components, including the anterior (iliopubic) column, posterior (ilioischial) column, anterior wall, posterior wall, quadrilateral plate (medial wall), and dome. An anterior column fracture occurs when there is a break that extends through the anterior wall and into the ischiopubic segment of the pelvis, while a posterior column fracture involves a break that extends through the posterior wall and disrupts the ilioischial line. A transverse acetabular fracture is characterized by a fracture that crosses both columns but does not completely disrupt the dome of the acetabulum, allowing a portion of the dome to remain attached to the iliac wing. During the procedure, a surgical incision is made over the hip joint to gain access to the fracture site. The hip joint is then thoroughly debrided and irrigated to remove any loose fragments and debris. Following this, the fracture is carefully reduced, and the anatomic alignment is verified using radiographic imaging. To stabilize the fracture, permanent fixation devices are applied, which may include a combination of lag screws and plate and screw devices. In the case of lag screw fixation, the outer cortex of the bone is over-drilled, and the screws are inserted perpendicularly to the fracture site. For plate and screw fixation, a reconstruction plate is positioned along the acetabular surface at the fracture site and secured with lag screws. In instances of posterior column fractures, an additional plate may be placed from the ischial tuberosity to the lateral ilium. Additionally, bone grafts that are separately reportable may be utilized to further secure the fracture fragments, ensuring proper healing and stability of the hip joint.

1. Indications

The open treatment of acetabular fractures as described by CPT® Code 27227 is indicated for specific types of fractures involving the acetabulum. These indications include:

  • Anterior Column Fracture A fracture that extends through the anterior wall and into the ischiopubic segment of the pelvis, necessitating surgical intervention for stabilization.
  • Posterior Column Fracture A fracture that extends through the posterior wall and disrupts the ilioischial line, requiring open treatment to restore the integrity of the hip joint.
  • Transverse Acetabular Fracture A fracture that runs transversely across the acetabulum, affecting both columns but not completely disrupting the dome, which requires surgical fixation to ensure proper alignment and healing.

2. Procedure

The procedure for the open treatment of acetabular fractures involves several critical steps to ensure effective stabilization and healing of the fracture. The following procedural steps are performed:

  • Incision and Exposure A surgical incision is made over the hip joint to provide access to the acetabulum. This incision allows the surgeon to visualize the fracture site and surrounding structures.
  • Debridement and Irrigation Once the fracture is exposed, the hip joint is thoroughly debrided to remove any loose fragments, debris, or damaged tissue. The area is then irrigated to ensure a clean surgical field, which is essential for reducing the risk of infection.
  • Fracture Reduction After debridement, the fracture is carefully reduced to restore the normal anatomical alignment of the acetabulum. This step is crucial for the proper function of the hip joint and is verified radiographically to ensure accurate positioning.
  • Application of Internal Fixation Devices Following successful reduction, permanent fixation devices are applied to stabilize the fracture. This may involve the use of lag screws, which are inserted into the bone after over-drilling the outer cortex, or plate and screw devices, where a reconstruction plate is placed along the acetabular surface and secured with lag screws.
  • Additional Fixation for Posterior Column Fractures In cases of posterior column fractures, a second plate may be placed from the ischial tuberosity to the lateral ilium to provide additional stability and support to the fracture site.
  • Bone Grafting If necessary, separately reportable bone grafts may be utilized to further secure the fracture fragments, promoting healing and ensuring the structural integrity of the acetabulum.

3. Post-Procedure

Post-procedure care following the open treatment of acetabular fractures involves monitoring the patient for any complications and ensuring proper recovery. Patients are typically advised on weight-bearing restrictions and may require physical therapy to regain strength and mobility in the hip joint. Follow-up appointments are essential to assess the healing process through radiographic imaging and to make any necessary adjustments to the treatment plan. Pain management and rehabilitation strategies are also discussed to facilitate a successful recovery.

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).
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).
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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) 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).
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.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 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).
