Does Medicare Cover IV Therapy & Infusion? Eligibility & Requirements

Q: Did Medicare change home infusion coverage recently?

Yes. The Consolidated Appropriations Act of 2018 created a new Medicare home infusion therapy (HIT) benefit effective January 1, 2021. Under this new benefit, Medicare Part B pays for professional services (nursing visits, training, and monitoring) for certain home infusion drug therapies. The drugs themselves continue to be covered under Part B (if a DESI drug) or Part D (most other drugs). Contact your home infusion pharmacy about how your specific therapy is covered under the updated benefit.

Q: Are IV antibiotics covered by Medicare at home?

It depends. IV antibiotics administered via infusion pump are generally covered under Medicare Part B when administered via an infusion pump as a benefit for certain parenteral drug therapies — specifically drugs that qualify as "not usually self-administered." Antibiotic therapy for osteomyelitis, endocarditis, and similar serious infections is commonly covered. Nursing services for PICC care and monitoring may be covered under the Home Infusion Therapy benefit or Medicare Home Health if the patient is homebound.

Q: Does Medicare cover TPN (total parenteral nutrition) at home?

Yes. TPN is covered under Medicare Part B as a prosthetic benefit when the patient has a permanent impairment of the gastrointestinal tract requiring enteral or parenteral nutrition as the primary source of nutrition. Coverage includes the PN solution, infusion pump, supplies, and nursing services. Documentation of the underlying GI condition and medical necessity is required. TPN is not subject to capped rental — it is covered as a prosthetic item.

Q: What is the Medicare Home Infusion Therapy (HIT) benefit?

The Medicare Home Infusion Therapy (HIT) benefit, effective January 2021, covers professional services related to home infusion — specifically nursing visits for assessment, training, monitoring, and PICC/port care — for Medicare Part B beneficiaries receiving eligible home infusion drug therapies. The benefit pays per visit for training and per diem for professional services. Not all home infusion therapies qualify; the drug must be covered under Part B.

Q: Does Medicare Part D cover home infusion drugs?

Medicare Part D (prescription drug benefit) covers most self-administered drugs, but home infusion drugs administered via pump are generally excluded from Part D. Many infusion drugs are covered under Medicare Part B as "incident to" physician services or under the prosthetic benefit (TPN) or DME benefit (insulin pumps). The coverage pathway depends on the specific drug and how it is administered. Your home infusion pharmacy will determine the correct billing pathway.

Updated April 2026

Medicare coverage for home IV therapy is among the most complex topics in DME — with drugs covered under Part B or Part D, equipment under the DME benefit, and professional services under the new Home Infusion Therapy benefit. Understanding the pathways before starting therapy prevents unexpected costs.

Understanding Medicare Infusion Coverage Pathways

Home infusion coverage under Medicare is split across multiple benefit categories. The pathway that covers your therapy depends on the drug, the device used to administer it, and your clinical situation:

Therapy	Coverage Pathway	Key Requirements
IV antibiotics (pump)	Part B (DME + HIT benefit)	Diagnosis; physician order; enrolled supplier
TPN/Parenteral Nutrition	Part B (prosthetic benefit)	Permanent GI impairment documented
Insulin pump infusion	Part B (DME benefit)	Failed MDI; clinical criteria met
IVIG (IV immunoglobulin)	Part B (covered drug benefit)	Primary immune deficiency diagnosis
Biologic infusions (Remicade, etc.)	Part B (infusion drug benefit)	Diagnosis; physician order; enrolled infusion center or HIT provider
Home hydration (IV fluids)	Part B (HIT benefit, some cases)	Limited coverage; typically acute/hospital-related
Most oral medications used in infusion	Part D	Standard prescription drug coverage

Medicare coverage for home infusion is complex, and coverage decisions vary by specific drug, diagnosis, DME MAC jurisdiction, and whether the patient has Original Medicare vs. Medicare Advantage. Always verify coverage through your home infusion pharmacy BEFORE starting therapy to avoid unexpected bills.

The Home Infusion Therapy (HIT) Benefit

Effective January 1, 2021, Medicare Part B pays for professional services provided by a Home Infusion Therapy supplier when a Part B-covered drug is being administered via an infusion pump at home:

Covered professional services: Initial patient training, nursing visits for drug administration start-up and monitoring, PICC/port assessment and dressing changes
Covered drug categories: Drugs covered under Part B used for home infusion (antibiotic, TPN, insulin pump therapy, IV immunoglobulin for specific diagnoses)
Not covered: Drugs typically covered under Part D when taken orally; experimental or investigational infusion drugs; administration by unlicensed individuals
Supplier requirements: HIT supplier must be accredited and Medicare-enrolled

What Is Not Covered

Most home infusion drugs are NOT covered when administered for outpatient infusion — Part B typically covers the drug administration in the physician's office or outpatient hospital setting
Infusion drugs not in the Medicare Part B drug benefit (check the specific drug's coverage status)
Services provided by non-Medicare-enrolled home infusion suppliers
First doses of high-risk drugs typically administered in supervised settings
Patient-purchased infusion pumps, tubing, and supplies from non-enrolled suppliers
