Summary & Overview
HCPCS L7405: Upper Extremity Prosthesis Addition for Shoulder Disarticulation, Acrylic
HCPCS Level II code L7405 denotes an addition to an upper extremity prosthesis for patients with shoulder disarticulation or interscapular thoracic amputations made from acrylic material. This code represents a specialized prosthetic component used to adapt or customize high-level upper limb prostheses, reflecting a niche but clinically important segment of prosthetic care focused on complex fittings and patient-specific fabrication. Nationally, accurate coding for such additions affects coverage decisions, billing consistency, and access to appropriate prosthetic customization for beneficiaries.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of what L7405 represents clinically and operationally, followed by benchmarking and payer coverage context where available. The publication provides: (1) an overview of the clinical context for shoulder disarticulation/interscapular thoracic prostheses and the role of acrylic additions; (2) typical sites of service and service-line implications for prosthetics and orthotics providers; and (3) summaries of payer coverage patterns and coding considerations relevant to billing and documentation. Data not available in the input is noted where specific payer policies, taxonomies, ICD-10 mappings, related codes, and detailed service-line metrics are required.
Billing Code Overview
HCPCS Level II code L7405 describes an addition to an upper extremity prosthesis for shoulder disarticulation/interscapular thoracic amputation levels, constructed of acrylic material. The service type is an upper extremity prosthetic component addition intended to augment or customize a prosthetic socket or structure for high-level shoulder amputations. The typical site of service is an outpatient prosthetics or orthotics clinic or a prosthetic fabrication laboratory equipped to fit and deliver upper extremity prostheses for shoulder disarticulation and interscapular thoracic patients.
Clinical & Coding Specifications
Clinical Context
A 48-year-old male patient with a right shoulder-level amputation (shoulder disarticulation) presents for fitting of a custom prosthetic socket and component additions. The prosthetist evaluates residual limb shape, scapular and thoracic contours, and functional goals (cosmetic restoration, suspension, and stability for transfers). The service involves fabrication and addition of an acrylic material component integrated into an upper extremity prosthesis for a shoulder disarticulation/interscapular thoracic level. Workflow typically includes prosthetic evaluation, cast or digital scan of the torso and residual limb, ordering and fabrication of the acrylic addition in the prosthetics lab, fitting session to adjust fit and suspension, and follow-up visits for adjustments and patient training. Documentation includes the amputation level, sidedness, prior prosthetic history, functional status, measurements/scans, description of the acrylic addition, time and materials used, and any complications or additional services provided.
