Home infusion/specialty pharmacy
Home infusion therapy is the administration of acute and chronic medications using intravenous, subcutaneous, epidural and enteral routes, which allows patients to receive therapy at home.
These therapies are covered under the UnitedHealthcare medical benefit as they require a clinician, such as a nurse, for the administration of the drug. Drugs covered under the pharmacy benefit are self-administered and do not require a clinician (e.g., nurse) for administration of the drug.
UnitedHealthcare contracts for home infusion services include 3 components:
- Drugs which can include both acute and chronic medications
- Acute medications are commonly used to support hospital discharges and have a short-term duration (e.g., antibiotics)
- Chronic medications commonly have longer-term duration and are used to support management of chronic diseases (e.g., Remicade® or immunoglobulin (IVIG))
- Nursing services for administration of the drug (this does not mean home infusion is a home health provider)
- Per diems which cover administrative services that are inclusive of clinical management, supplies, equipment, delivery, drug compounding, hazardous waste disposal and standard additives for nutritional products (not all drugs require a per diem)
