Infusion IV Therapy FAQs

What is infusion therapy?

Infusion therapy involves the administration of medication through a needle or catheter. It is prescribed when a patient’s condition is so severe that it cannot be treated effectively by oral medications. Typically, “infusion therapy” means that a drug is administered intravenously, but the term also may refer to situations where drugs are provided through other non-oral routes, such as intramuscular injections and epidural routes (into the membranes surrounding the spinal cord).

“Traditional” prescription drug therapies commonly administered via infusion include antibiotic, antifungal, antiviral, chemotherapy, hydration, pain management and parenteral nutrition.

Infusion therapy is also provided to patients for treating a wide assortment of often chronic and sometimes rare diseases for which “specialty” infusion medications are effective. While some have been available for many years, others are newer drugs and biologics. Examples include blood factors, corticosteroids, erythropoietin, infliximab, inotropic heart medications, growth hormones, immunoglobulin, natalizumab and many others.

What diseases are treated with infusion therapy?

Diseases commonly requiring infusion therapy include infections that are unresponsive to oral antibiotics, cancer and cancer-related pain, dehydration, gastrointestinal diseases or disorders which prevent normal functioning of the gastrointestinal system, and more. Other conditions treated with specialty infusion therapies may include cancers, congestive heart failure, Crohn’s Disease, hemophilia, immune deficiencies, multiple sclerosis, rheumatoid arthritis, and more.

By far, the major home infusion therapies are IV antibiotics, prescribed primarily for such diagnoses as cellulitis, sepsis, and osteomyelitis; other diagnoses include urinary tract infections, pneumonia, sinusitis and more.

Why are infusions performed at home?

Until the 1980s, patients receiving infusion therapy had to remain in the inpatient setting for the duration of their therapy. Heightened emphasis on cost-containment in health care, as well as developments in the clinical administration of the therapy, led to strategies to administer infusion therapy in alternate settings. For individuals requiring long-term therapy, inpatient care is not only tremendously expensive but also prevents the individual from resuming normal lifestyle and work activities.

The technological advances that enabled safe and effective administration of infusion therapies in the home, the desire of patients to resume normal lifestyles and work activities while recovering from illness, and the cost-effectiveness of home care are important. Consequently, home infusion therapy has evolved into a comprehensive medical therapy that is a much less costly alternative to inpatient treatment in a hospital or skilled nursing facility.

Home infusion has been proven to be a safe and effective alternative to inpatient care for many disease states and therapies. For many patients, receiving treatment at home or in an outpatient infusion suite setting is preferable to inpatient care. A thorough patient assessment and home assessment are performed before initiating infusion therapy at home to ensure that the patient is an appropriate candidate for home care.

What is a home infusion therapy provider?

An infusion therapy provider is most normally a “closed-door”, state-licensed pharmacy that specializes in provision of infusion therapies to patients in their homes or other alternate-sites. The infusion therapy always originates with a prescription order from a qualified physician who is overseeing the care of the patient.

A nationally-accepted, technical definition of a home infusion therapy pharmacy is a:

Pharmacy-based, decentralized patient care organization with expertise in USP 797-compliant sterile drug compounding that provides care to patients with acute or chronic conditions generally pertaining to parenteral administration of drugs, biologics and nutritional formulae administered through catheters and/or needles in home and alternate sites. Extensive professional pharmacy services, care coordination, infusion nursing services, supplies and equipment are provided to optimize efficacy and compliance.

Qualified infusion pharmacies must satisfy licensing and other regulatory requirements imposed by state pharmacy boards as well as accreditation standards required by most third-party payers. Home infusion pharmacies may also provide additional professional therapies and services, including enteral nutrition therapy, inhalation therapies using nebulizers, and disease state and care management services.

Pharmacy organizations providing infusion therapy include local, regional, and national organizations. Some are independent pharmacies. Others are affiliated with hospitals, home nursing agencies, traditional retail pharmacies, respiratory therapy suppliers or other health care providers.

What are the highly specialized services, supplies and equipment obtained from an infusion pharmacy that are necessary to ensure quality practices and outcomes?

Pertaining directly to the medications used, the infusion pharmacy ensures that infusion drugs are:

  • Compounded in a sterile environment.
  • Maintained in appropriate conditions to ensure sterility and stability.
  • Administered at exactly the right dose and on the right schedule.
  • Administered using the appropriate vascular access device (often a long-term device) which is placed in the correct anatomical location based on the expected duration of therapy, the pH, osmolarity, and osmolality of the medication.
  • Administered using an appropriate drug delivery device.
  • Flushed with the proper flushing solution between doses.
  • Monitored for adverse reactions and therapeutic efficacy.

No less important, infusion pharmacies provide an extensive array of professional services — patient assessment and admission, education and training, care planning and coordination, care management by clinical infusion pharmacists, trouble-shooting and treatment plan oversight, and much more—all essential to achieving high-quality outcomes for patients receiving infusion therapy.

Also essential are the specialized equipment (infusion pumps and poles) and many administration supplies (such as IV sets, syringes, and more) required for infusion therapy. The infusion pharmacy also supplies these to the patient and services the equipment when necessary

What is the extensive array of professional services performed by infusion pharmacies?

To ensure safe and proper administration of infusion drugs, infusion pharmacies provide the following services:

  • Comprehensive assessment that considers patient history, current physical and mental status, lab reports, cognitive and psychosocial status, family/care partner support, prescribed treatment, concurrent oral prescriptions, and over-the-counter medications.
  • Maintenance of appropriate procedures for the compounding and distribution of sterile infusion products as outlined in the national standards and state and federal regulations.
  • Drug interaction monitoring and identification of potential drug, dose or drug catheter incompatibilities.
  • Comprehensive admission procedures that include patient education of medical and disposable equipment use, medication storage and handling, emergency procedures, vascular access device management, recognition and reporting of adverse drug reactions.
  • Comprehensive care planning that considers actual or potential drug or equipment-related problems, therapy monitoring with specific patient goals, and coordination of activities with other providers such as home health agencies and physicians.
  • Ongoing patient monitoring and reassessment activities to continually assess for response to treatment, drug complications, adverse reactions, and patient compliance.
  • Laboratory report reviews, as applicable, and subsequent consults with care professionals to adjust medication orders if necessary.
  • Maintenance of appropriate physical facilities for storage, preparation, dispensing, and quality control of all infusion medications and equipment.
  • Ongoing employee education and competence validation activities.
  • Performance improvement programs that include collection of clinical outcomes data, patient perception data, trending and analysis of these and other performance measurement data, and root cause evaluations of all sentinel events.

These essential specialized services listed above, as well as many other services, equipment and supplies needed for infusion therapy, are paid for by the majority of health insurance plans under a per diem payment system. The NHIA National Definition of Per Diem provides a complete list of everything included in per diem payment.

Are home infusion pharmacies accredited?

While accreditation is voluntary, most commercial insurers require infusion pharmacies to be accredited to serve their patients. The three organizations primarily involved in accrediting infusion therapy pharmacies are the Accreditation Commission for Health Care, the Community Health Accreditation Program and the The Joint Commission. Learn more about the requirements that must be met by accredited infusion pharmacies.

Do government and private insurance plans cover infusion therapy in the home and other alternate-sites?

The range of variables that must be managed by the infusion pharmacy to ensure safe and appropriate administration has led nearly all commercial health plans to treat home infusion therapy as a medical service, reimbursed under their medical benefit (rather than the prescription drug benefit) and paid for using a per diem for clinical services, supplies, and equipment with separate payments for the drugs and nursing visits. It also has led most commercial plans to require that infusion pharmacies be accredited by nationally recognized accreditation organizations. Commercial plans have used this model aggressively to reduce overall health care costs while achieving high levels of patient satisfaction.

Government health plans such as Medicaid, TRICARE, and the Federal Employees Health Benefits Program also reimburse for home infusion therapy, although for Medicaid in a few states the extent of coverage can have gaps. A major exception in completeness of coverage is, unfortunately, the Medicare program.

For infusion therapy provided in Ambulatory Infusion Suites, commercial insurers are fast recognizing the appropriateness of this infusion setting and its cost-competitiveness with other Ambulatory Infusion Center settings. Medicaid coverage varies by state. Medicare’s prescription drug plan (Part D) may cover the cost of the infusion drugs, but the costs of AIS services, supplies, equipment and nursing are not covered. The infusion therapy provider will ascertain coverage for patients and advise on the extent of coverage and patient obligations prior to start of service.

Does medicare cover home infusion therapy?

Unfortunately, Medicare’s fee-for-service program (Parts A, B and D) is the only major health plan in the country that has not recognized the clear benefits of adequately covering provision of infusion therapies in a patient’s home. Because most Medicare beneficiaries are enrolled in the fee-for-service program, when seniors and the disabled find they may need infusion therapy they often find it unaffordable to receive this care in the comfort of their home.

Providing home infusion therapy involves not only the delivery of medication, but also requires professional services, specialized equipment and supplies to ensure safe and effective administration of the therapy. While most infusion drugs may be covered by the Medicare Part D prescription drug benefit, the Centers for Medicare & Medicaid Services (CMS) has determined that it does not have the authority to cover the infusion-related services, equipment and supplies under Part D. As a result, many Medicare beneficiaries are effectively denied access to home infusion therapy and are being forced into receiving infusion therapy in hospitals and skilled nursing facilities at a significantly higher cost to Medicare and at great inconvenience to the patients. NHIA is underway with a critical legislation initiative to rectify this situation.

In Medicare Part B, there is some coverage for certain therapies administered using durable medical equipment (a mechanical or electronic external infusion pump). Unfortunately, only a select few therapies are covered and only under very specific conditions. These include some anti-infective, some chemotherapy drugs, some inotropic therapies (e.g., dobutamine), some pain management, immune globulin administered subcutaneously, and a few other therapies. For parenteral and enteral nutrition therapies, there can be coverage in Part B only if the need for the therapy is documented to be for at least 90 days and other coverage criteria are met. There may be coverage for intravenous immune globulin (IVIG) for primary immune deficiency patients but the supplies and equipment are not paid for. More specific information can be obtained by contacting the Medicare entities called Durable Medical Equipment Medicare Administrative Contractors (DME MACs). The coverage criteria for home infusion that all contractors follow are found from a DME MAC.

For home nursing visits needed for beneficiaries receiving infusion therapy, there can be Medicare Part A coverage under Medicare’s home health benefit only if the patients are serviced by a Medicare-certified home health agency, as well as considered to be homebound and in need of intermittent (not 24 hour) home nursing. NHIA’s Medicare legislation initiative is intended to broaden this gap in coverage too.

Some Medicare fee-for-service plan patients may have other insurance that will pick up some of the home infusion costs not covered by Medicare. A minority of the Medicare population is enrolled in the Medicare Advantage (Part C) program. Similar to most commercial health plans, many Medicare Advantage health plans cover home infusion because they recognize it will reduce their overall health care costs and achieve high levels of patient satisfaction.

Most home infusion therapy providers are familiar with Medicare’s coverage details and will advise prospective patients of their specific coverage and anticipated out-of-pocket obligations should they undertake home infusion therapy.
