Summary & Overview
HCPCS L1710: Legg Perthes Orthosis, Newington Type, Custom Fabricated
HCPCS Level II code L1710 designates a custom-fabricated Legg Perthes orthosis (Newington type), a specialized lower-extremity brace used to manage hip stability and gait in patients with Legg-Calvé-Perthes disease. Nationally, this code matters for durable medical equipment (DME) and orthotics billing because custom fabrication affects coverage determinations, documentation requirements, and reimbursement compared with off-the-shelf devices. Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise overview of what L1710 represents, payer coverage patterns and benchmarks, and the clinical context for use of a Newington-type orthosis. The publication summarizes applicable billing considerations such as typical sites of service, utilization drivers tied to pediatric hip disorders, and common documentation elements insurers request for custom-fabricated orthoses. It also highlights policy updates that affect prior authorization and medical necessity review for custom devices, and provides comparative benchmarks where available. Data not available in the input is noted where applicable.
Billing Code Overview
HCPCS Level II code L1710 denotes a Legg Perthes orthosis (Newington type), custom fabricated. This orthotic device is a custom-made protective and corrective lower-extremity brace designed specifically for patients with Legg-Calvé-Perthes disease to support hip joint alignment and gait mechanics.

Clinical & Coding Specifications
Clinical Context
A pediatric patient, typically a child aged 3–10 years, presents with unilateral hip pain, limp, and reduced range of motion after an episode of atraumatic onset or delayed presentation following hip pain. Imaging (plain radiographs or MRI) confirms Legg–Calvé–Perthes disease with femoral head osteonecrosis and varying degrees of collapse and subchondral fragmentation. An orthotist receives a prescription from a pediatric orthopedic surgeon for a custom-fabricated Legg Perthes orthosis (L1710, Newington type) to provide containment of the femoral head, limit abduction/adduction extremes, and maintain appropriate hip positioning during the active disease phase.
Clinical workflow:
-
Referral: Pediatric orthopedic surgeon documents diagnosis, clinical goals, and measurable parameters (hip range of motion, abduction angle, weight-bearing status) and sends a written order to the orthotics clinic.
-
Evaluation: Certified orthotist performs a focused assessment including hip measurements, gait observation, skin inspection, and functional goals. The orthotist documents measurements and selects the Newington-style design for custom fabrication.
-
Fabrication: A custom device is fabricated using cast or digital scanning, thermoplastic materials, and appropriate padding to offload areas at risk. The device is coded as
L1710for a Newington-type Legg Perthes orthosis, custom fabricated. -
Fitting and training: Orthotist fits the device, adjusts straps/closures, checks alignment and pressure points, provides caregiver education on wear schedule, skin care, and safe transfers, and documents fit and instructions.
-
Follow-up: Periodic clinic follow-up coordinated with the orthotist and pediatric orthopedic surgeon for device adjustments, growth accommodations, and outcomes monitoring until skeletal healing and clinical goals are met.
