Reimbursement for outpatient parenteral antibiotic therapy: update.

Reimbursement policies of third-party payers, including Medicare, reflect a variety of coverage patterns. For a limited group of Medicare patients who are, in Medicare terms, confined to home and require skilled and intermittent care, Medicare Part A covers home care services deemed medically necessary by a physician. Medical equipment and supplies may be included under this coverage. Medicare Part B covers physician services, laboratory tests, and drugs used by out-patients. The latter must be administered directly by a physician or by an employee of a physician with direct supervision by a physician. These restrictions have, in general, prevented reimbursement by Medicare for iv antibiotic therapy in the home. Medicaid, Blue Cross/Blue Shield, various commercial insurers, and health maintenance organizations usually cover iv antibiotics, but in many cases prior approval is necessary for coverage.
