CPT 27226: Open Fixation of Acetabular Wall Fracture
CPT code 27226 represents open surgical repair of a posterior or anterior acetabular wall fracture with internal fixation (plates, pins, or screws). This orthopedic trauma procedure is performed to restore acetabular stability, joint congruity, and to reduce the risk of post-traumatic arthritis. Nationally, acetabular fracture care has implications for trauma systems, hospital surgical capacity, and payer coverage for complex inpatient and same-day surgical episodes.
Key payers referenced in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines what readers should expect about clinical context, common sites of service, and payer coverage considerations for this procedure.
Readers will learn: benchmarks for service utilization and site-of-service patterns where available; how CPT code 27226 is described and applied in clinical documentation; and policy-relevant facts that affect billing and reimbursement for open acetabular wall fixation. Data not available in the input is noted where applicable.

Billing Code Overview
CPT code 27226 describes an open treatment of an acetabular wall fracture (posterior or anterior) using internal fixation implants such as plates, pins, or screws. The procedure involves surgical exposure of the acetabulum and direct fixation of the fractured posterior or anterior wall to restore joint stability and anatomic alignment.
Service Type: Open surgical fracture fixation (orthopedic trauma surgery)
Typical Site of Service: Inpatient hospital or ambulatory surgical center, depending on clinical status and complexity
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult who sustained a high-energy pelvic injury after a motor vehicle collision or a fall from height and presents with severe hip pain, inability to bear weight, and radiologic evidence of an acetabular wall fracture (posterior or anterior). Initial evaluation occurs in the emergency department with trauma survey, pelvic and hip radiographs, and CT pelvis with 3D reconstructions to define fracture pattern. After stabilization and appropriate clearance by trauma and medical services, an orthopedic trauma surgeon schedules open reduction and internal fixation of the acetabular wall using plates, screws, and/or pins. The procedure is performed in an inpatient operating room under general anesthesia with intraoperative fluoroscopy. Postoperatively the patient is monitored for neurovascular status, received DVT prophylaxis, and undergoes physical therapy with weight-bearing restrictions determined by fixation stability. Subsequent follow-up visits include wound checks, radiographic assessment of fracture healing, and gradual progression of weight bearing.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the procedure requires substantially greater work than usual due to complexity, extensive dissection, or intraoperative complications. |
23 | Unusual anesthesia | Use when general anesthesia is medically contraindicated and an unusual form of anesthesia is administered for an otherwise normally anesthetized procedure. |
26 | Professional component | Use if billing separately for the physician professional component when technical component is billed by facility (rare for this surgical procedure). |
50 | Bilateral procedure | Use when both acetabular walls are treated in the same operative session (rarely applicable but included when bilateral fixation performed). |
51 | Multiple procedures | Use when other unrelated procedures are performed at the same operative session in addition to the acetabular fixation. |
52 | Reduced services | Use when the full procedure is not completed or is intentionally reduced (partial fixation). |
53 | Discontinued procedure | Use if the procedure is started but discontinued due to extenuating circumstances or patient safety. |
59 | Distinct procedural service | Use to indicate a separate and distinct procedure when other services on the same day might be bundled. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons performing distinct portions of the procedure (co-surgery). |
66 | Surgical team | Use when a surgical team approach is reported for complex cases requiring multiple surgeons of the same specialty. |
78 | Return to OR for related procedure during global period | Use when the patient returns to the operating room for a related procedure during the postoperative global period (unplanned reoperation). |
79 | Unrelated procedure during global period | Use when an unrelated procedure is performed during the global period. |
80 | Assistant surgeon | Use when an assistant surgeon is present (usually requires documentation and appropriate taxonomy/credentialing). |
LT | Left side | Use to indicate laterality when the left acetabular wall is treated. |
RT | Right side | Use to indicate laterality when the right acetabular wall is treated. |
