Summary & Overview
HCPCS L3310: Neoprene Heel and Sole Lift, Per Inch
HCPCS Level II code L3310 denotes a neoprene lift for the heel and sole, billed per inch. The code applies to adjustable orthotic or shoe modification accessories used to alter heel height for clinical reasons such as limb length discrepancy, gait abnormality, or pressure redistribution. Nationally, utilization of appliance-level HCPCS codes like L3310 matters for durable medical equipment coverage policy, supplier billing, and standardization of orthotic modifications across payers.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for use of a neoprene heel and sole lift, typical sites of service where the item is provided, and the payer landscape relevant to coverage and billing practice. The publication summarizes common billing modifiers and payer considerations, provides benchmark guidance where available, and highlights policy updates that affect durable medical equipment and orthotics reimbursement. Data not available in the input is noted where applicable. This resource is intended to clarify the billing purpose, clinical applicability, and payer scope for L3310 at a national level.

Typical site of service: Durable medical equipment suppliers, orthotics and prosthetics clinics, podiatry or orthopedic outpatient settings where shoe modifications or orthotic fittings are performed.
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with a leg-length discrepancy or footwear-related posterior heel pain who presents to an orthotic/prosthetic clinic or a podiatry/orthopedic outpatient clinic. The clinician measures the required lift height in inches and prescribes a heel-and-sole lift constructed of neoprene material to be bonded into the shoe or applied as an insert. The workflow includes evaluation of gait and limb length, documentation of measurement in inches, selection of lift material (neoprene) and height, fabrication or dispensing of the lift (often per inch charged), verification of fit in the shoe, and brief instruction on wear. The service is commonly billed by orthotists, prosthetists, podiatrists, or orthopedists in an outpatient setting or durable medical equipment supplier when providing custom or preformed lifts. Typical scenarios include postoperative limb-length correction, management of Achilles tendinopathy with heel lift, or symptomatic leg-length inequality affecting gait.
