Summary & Overview
HCPCS L3610: Transfer of Caliper Plate Orthosis
HCPCS Level II code L3610 denotes the transfer of an orthotic caliper plate from one shoe to another. The code captures a specific orthotic service that preserves ambulatory support without issuing an entirely new device. Nationally, this code matters because it impacts durable medical equipment workflows, claims editing, and reimbursement for orthotics services provided in outpatient and supplier settings.
Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn what L3610 represents clinically and operationally, which payers commonly recognize the code, and how it fits into documentation and service-line workflows. The publication highlights billing benchmarks, common payer coverage patterns, and relevant clinical context for orthotic transfers. It also outlines where to expect the service to be provided—typically in outpatient clinics, orthotics/prosthetics suppliers, or shoe fitting locations—and describes the practical implications for claims processing and coding consistency.
Data not available in the input for specific modifiers, taxonomies, ICD-10 pairings, or related codes is noted where applicable in detailed sections.

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with a longstanding right-sided drop foot uses an ankle-foot orthosis (AFO) with a caliper plate mounted to a shoe. The patient presents to a prosthetics and orthotics clinic for replacement shoes; the existing caliper plate orthosis must be transferred from the patient’s old shoe to a new shoe that better fits current activity and wound-free skin. The orthotist inspects the orthosis and shoe interfaces, documents the need to transfer the caliper plate rather than fabricate a new orthosis, and performs the transfer: removing fasteners from the old shoe, aligning and attaching the caliper plate to the new shoe, verifying medial-lateral alignment and heel height, and testing gait in the clinic. The service is billed as L3610 (Transfer of an orthosis from one shoe to another, caliper plate, new). Typical workflow includes verification of patient identity and payer, orthotic assessment, device transfer, function testing, documentation of reason for transfer and materials used, and scheduling follow-up for fit and skin checks. Typical site of service is an outpatient prosthetics and orthotics clinic or hospital outpatient department. Common clinical reasons for transfer include shoe wear-out, change in foot size, new diabetic shoe ordering with continued use of existing caliper plate, or replacement shoe due to damage.
