HCPCS L3600: Transfer of Caliper Plate Orthosis from One Shoe to Another
HCPCS Level II code L3600 covers the transfer of an existing caliper plate orthosis from one shoe to another. This code is used when a previously provided orthotic component is removed and refitted into different footwear rather than replaced. Nationally, accurate use of L3600 affects durable medical equipment billing, inventory tracking, and patient continuity of orthotic care.
Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The review highlights payer coverage patterns and coding expectations relevant to orthotic component transfers.

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with a longstanding ankle-foot orthosis (AFO) that includes a caliper plate presents to an orthotics clinic for follow-up after obtaining a new pair of shoes. The patient ambulates with gait instability due to peripheral neuropathy and drop foot. The orthotist inspects the existing orthosis, verifies fit and alignment, removes the caliper plate and associated hardware from the old shoe, and transfers and secures the caliper plate and attachments into the new shoe. The workflow includes confirming the device is an existing orthosis (not new fabrication), documenting the transfer procedure, checking for wear or damage, making minor adjustments to fasteners or pads, performing a brief static gait assessment, and providing patient education on proper donning, doffing, and shoe selection. Time on task is typically 15–45 minutes depending on complexity. Billing uses L3600 for transfer of an orthosis caliper plate from one shoe to another, existing, with modifiers as applicable and documentation that the orthosis component was previously furnished.
