Summary & Overview
HCPCS L3300: Heel Elevation Lift, Tapered to Metatarsals, Per Inch
HCPCS Level II code L3300 represents a per-inch orthotic modification: a lift that elevates the heel and tapers to the metatarsals. This durable medical equipment (DME) code is used when providers or suppliers add incremental heel elevation to footwear or orthoses, and it matters nationally because appropriate coding ensures consistent billing for custom shoe modifications and orthotic interventions that address gait, limb length discrepancy, or pressure redistribution.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will get a concise policy and billing overview for L3300, learn typical service settings and clinical contexts where the code applies, and find guidance on common modifiers and billing practices. The publication summarizes payer coverage tendencies, documentation expectations, and where to look for medical necessity criteria. It also highlights benchmarking areas such as average utilization and reimbursement patterns when available.
This summary is intended for billing managers, orthotics and prosthetics suppliers, podiatry and orthopedic clinical teams, and compliance officers seeking a national-level reference for coding and billing of heel elevation modifications billed per inch under HCPCS Level II code L3300. Data not available in the input is noted where applicable.
Billing Code Overview
HCPCS Level II code L3300 describes a lift, elevation, heel, tapered to metatarsals, per inch. This item is an orthotic build modification intended to increase heel elevation while tapering toward the metatarsal region, measured and billed per inch of material added or adjusted.

Typical site of service: Durable medical equipment supplier, orthotics and prosthetics facility, or podiatry/orthopedics clinic supplying custom shoe modifications
Clinical & Coding Specifications
Clinical Context
A patient presents to a podiatry or orthotics clinic for evaluation of symptomatic leg-length discrepancy, Achilles tendon contracture, plantar fasciitis with heel pain, or asymmetric heel height after foot surgery. The clinician determines that a heel lift is required to correct limb length inequality or offload the posterior heel. An orthotist or podiatrist measures the required lift height and documents the need for a tapered heel lift extending to the metatarsals. The device is fabricated or adjusted per inch using prefabricated materials or inserts, and the clinician documents the amount of lift in inches and the medical necessity in the chart. Typical workflow: evaluation by the treating clinician, measurement and prescription of heel lift height (inches), fabrication or modification by orthotics staff, fitting and patient education, and billing using L3300 with appropriate modifier to indicate laterality, provider role, or unusual circumstances. Typical site of service is an outpatient clinic, orthotics/prosthetics facility, or ambulatory surgery/office-based setting when provided as part of conservative care.
