HCPCS Level II code E0935 designates a continuous passive motion (CPM) device intended for knee-only use. CPM devices are used to provide controlled passive movement of the knee joint, commonly in postoperative rehabilitation to preserve range of motion and reduce stiffness. Nationally, billing and coverage for DME items such as CPM devices affect post-acute care patterns and prosthetic/rehabilitative pathways for joint surgery patients.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the device’s clinical role and the payer landscape, plus information on coverage benchmarks, coding practice considerations, and relevant policy updates where available. The publication outlines typical sites of service and the service type classification to inform billing and revenue-cycle teams, clinicians, and compliance staff.

This summary addresses what E0935 represents, why accurate coding matters for reimbursement and utilization tracking, and what to expect in payer interactions and documentation requirements. Data not available in the input is noted where applicable.
