HCPCS Level II code E0665 identifies a non-segmental pneumatic appliance for use with a pneumatic compressor, designed to deliver circumferential compression to the full arm. This durable medical equipment code matters nationally because pneumatic compression devices are commonly prescribed for lymphedema, chronic venous insufficiency, and post-operative edema management, and coverage and utilization affect outpatient and home health care costs and access to therapy.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise national perspective on what the code represents, why it is used clinically, and what to expect in payer coverage patterns. The publication provides benchmarks where available, outlines typical sites of service and clinical contexts for use, and summarizes policy and coding considerations related to durable medical equipment provisioning of full-arm pneumatic compression systems.

This summary is intended to orient clinicians, billing staff, and policy analysts to the clinical role of the device, the primary payers involved, and the types of information covered in the full publication, including reimbursement benchmarks, common billing modifiers, and implementation issues. Data not available in the input will be noted where applicable.
