Medical necessity determined by NC Medicaid 5A-1

Coverage and medical necessity determinations are governed by the referenced state policy.

NC Medicaid governs medical necessity: Medical necessity clinical coverage criteria are those in the North Carolina Medicaid (Division of Health Benefits) Clinical Coverage Policy, Medical Equipment: 5A-1, Physical Rehabilitation Equipment and Supplies.

Providers must refer to that policy for specific indications, prior authorization requirements, and supporting documentation.

Inclusion of HCPCS codes in this policy is for reference only and does not guarantee coverage or payment. Benefit determination and medical necessity are governed by applicable federal, state, or contractual requirements; providers must follow the North Carolina Medicaid Clinical Coverage Policy, Medical Equipment: 5A-1, for specific indications, prior authorization requirements, and documentation rules. Use of codes not on the NC Medicaid Fee Schedule (marked with *) risks denial when billed to NC Medicaid.

Background

Pneumatic compression devices are medical devices that deliver intermittent or segmental pneumatic compression for conditions such as lymphedema and venous insufficiency. These devices are regulated by the U.S. Food and Drug Administration; many systems are cleared as Class II devices. Specific systems (for example, the FDA-cleared Flexitouch Plus System) have distinct clearances for particular indications (such as head and neck lymphedema). FDA clearance alone does not establish coverage—medical necessity and coverage decisions are determined by applicable coverage policies.
