Summary & Overview
CPT 27111: Iliopsoas Transfer to Femoral Neck for Hip Stability
CPT code 27111 represents a specialized orthopedic surgical procedure in which the iliopsoas muscle is transferred to the neck of the femur to improve lateral stability of the hip in patients with weakened hip abductor function. This reconstructive muscle-tendon transfer has implications for mobility, fall risk reduction, and functional outcomes following hip instability or abductor deficiency. Nationally, accurate coding for this procedure matters for clinical documentation, quality measurement, and appropriate payment for complex orthopedic surgery.
Major payers typically addressed in national analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, an overview of expected service setting and service type, and notes on common billing modifiers when data is available. The publication summarizes benchmarks and policy-relevant considerations such as coding specificity, typical sites of service, and alignment with surgical care pathways. The summary is intended to orient clinicians, coding professionals, and policy analysts to the code's clinical purpose and where to look for payer-specific coverage or reimbursement details. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 27111 describes a surgical iliopsoas transfer to the femoral neck performed to improve lateral hip stability by compensating for weak hip abductor muscles. The procedure involves detaching and relocating the iliopsoas muscle tendon to the neck of the femur to restore or enhance abductor function and hip joint stability.
-
Service type: Orthopedic reconstructive procedure (muscle transfer) intended to address hip abductor insufficiency and lateral instability.
-
Typical site of service: Inpatient or outpatient surgical setting, most commonly performed in an operating room within a hospital or ambulatory surgery center.
Clinical & Coding Specifications
Clinical Context
A typical patient for 27111 is an adolescent or young adult with chronic hip abductor insufficiency (for example, persistent Trendelenburg gait and lateral hip instability) following neuromuscular conditions, failed prior soft-tissue procedures, or congenital hip dysplasia. The patient commonly presents with lateral hip pain, gait deviation, and weakness on clinical exam. Imaging (radiographs, MRI) documents preserved femoral head structure but functional abductor deficiency. Conservative measures (physical therapy, bracing, activity modification) have been attempted without adequate functional improvement. The orthopedic surgical workflow includes preoperative evaluation with history and physical, gait analysis when available, informed consent discussing goals and risks, preoperative anesthesia evaluation, and perioperative antibiotic prophylaxis. Intraoperatively the iliopsoas tendon is identified, mobilized, and transferred to the femoral neck region to augment lateral stability; concurrent procedures (e.g., open reduction, corrective osteotomy) may be staged or performed as indicated. Postoperative care involves pain control, protected weight-bearing, physical therapy focused on gait retraining, and scheduled follow-up with serial clinical and radiographic assessment to document improved hip stability and function.
