UnitedHealthcare Enteral Nutrition Coverage Update

Coverage Criteria

Medical Necessity (State Code Reference)

Covered when criteria in Nebraska DHHS Code 471-7-004.02(V) are met

State-specified medical necessity: Medical necessity and coverage determinations for enteral and parenteral nutrition follow Nebraska Department of Health and Human Services Code 471-7-004.02(V). Providers must meet the clinical criteria in that code for coverage.refer to Code 471-7-004.02(V)

This policy delegates clinical criteria to the state regulation and does not restate the clinical rules.

The inclusion of a HCPCS code in this policy is for reference only and does not imply that the service described by the code is a covered or non-covered health service. Benefit coverage and payment determinations depend on applicable federal, state, or contractual requirements and laws; listing a code does not guarantee reimbursement or claim payment.

Coverage and payment are governed by applicable federal, state, and contractual benefit rules. Providers must verify the member’s plan and any governing regulations because services or items that do not meet federal, state, or contractual requirements — including the referenced Nebraska DHHS criteria — may not be covered.
