Prosthetic Limb Vacuum Systems (CPB 0630, reviewed 2026-09-09)
Aetna considers the eVAC, the Harmony Vacuum Management System (Vacuum Assisted Socket System, VASS), and the LimbLogic VS Prosthetic Vacuum Suspension System medically necessary for lower limb prostheses when the prosthesis criteria are met and at least one of these applies: excessive pistoning that cannot be resolved by suspension adjustments, excessive residual limb hyperemia or excessive skin hyperhidrosis from prior socket use, or multiple falls in below-knee (trans-tibial) amputees. The use of these systems for multiple falls in above-knee (trans-femoral) amputees is considered experimental, investigational, or unproven. Magnetic panels used to enlarge a trans-tibial prosthetic socket to facilitate limb fluid volume stabilization are considered experimental because the evidence is insufficient.

A microprocessor-controlled knee is considered investigational for individuals who do not meet these criteria, and a powered knee is considered investigational.
