Service line
Home infusion nursing: the pharmacy dispenses, the agency administers.
A patient who receives an infused drug at home is usually served by two organizations: a pharmacy ships the drug and a nursing agency sends the nurse. This page explains the nursing agency as a business, under which standards it works and how it is paid.
- Pharmacy referral
- Governing order confirmed
- Nurse matched by license, therapy, device and distance
- Visit scheduled against drug delivery
- Assessment and access care
- Administration and monitoring
- Teaching
- Note signed and reviewed
- Note returned to the pharmacy
- Invoice at the contract rate
- Payment reconciled
1. Two organizations, one patient
Home infusion is the administration of a drug through a needle or catheter somewhere other than a hospital or clinic. The work divides cleanly. The pharmacy receives the prescription, verifies coverage, compounds or prepares the drug, ships it with the pump and supplies, and manages the therapy clinically from a distance. The nurse is the only member of that team who stands in the patient’s home.
Some pharmacies employ their own nurses. Many do not, or not everywhere they ship, so they contract with independent nursing agencies. For that agency the pharmacy is the customer. The agency does not dispense, does not own the drug and usually does not bill the patient’s insurer. It sells a clinical service under an agreement, and most agencies hold agreements with several pharmacies at once.
The agency’s work therefore begins with a document it did not write, the pharmacy’s referral and order, and ends with a document it must send back, the nursing note. Why this segment is a useful starting point is set out in Why home infusion first, and the handoffs are described in The fragmented infusion nursing workflow. This page describes the business underneath them.
2. The therapies given at home
The National Home Infusion Association names intravenous antibiotics for serious infections as by far the most common reason for home infusion, followed by therapies for gastrointestinal disease, immune disorders, cancer, dehydration and chronic conditions treated with specialty biologics. For a nursing agency, each family is a different kind of visit and a different competency to prove.
| Therapy family | What it is, in outline | What it asks of the nursing agency |
|---|---|---|
| Anti-infectives | Antibiotics, antifungals and antivirals given intravenously, often after a hospital stay | A fast start, often on the day of discharge. Much of the nursing is teaching the patient or caregiver to give doses between visits, with line care and reassessment. |
| Immunoglobulin, intravenous | Immune globulin infused into a vein on a repeating cycle | A nurse present for a long infusion, with a rate that changes under the order and observation throughout. |
| Immunoglobulin, subcutaneous | Immune globulin infused under the skin, often by the patient after training | Training visits, a return demonstration, and a documented decision that the patient can continue independently. |
| Biologics and other specialty drugs | Infused or injected drugs for chronic inflammatory, neurologic and rare conditions | Therapy-specific competency, observation after the dose and any program requirements the pharmacy passes down. |
| Parenteral nutrition | Nutrition delivered into a central vein, usually cycled daily over long periods | Central line care, caregiver training on the pump, and laboratory draws on the pharmacy’s schedule. |
| Hydration | Fluids and electrolytes given intravenously | Short episodes, sometimes at short notice, often through a peripheral line placed at the visit. |
| Inotropes | Continuous cardiac infusions for advanced heart failure | A continuous pump, a central line that cannot be interrupted, and a plan for after-hours problems. |
| Pain management | Opioid and other infusions, intravenous or subcutaneous, often near the end of life | Pump programming under the order, controlled-substance handling under policy, and coordination with hospice. |
The table is an outline of operations, not a clinical reference. The prescriber’s order and the agency’s policies govern each visit.
3. Vascular access: what nursing has to know
Every infusion goes through a device, and the device decides much of the visit. Before it promises a visit, an agency has to know which device the patient has and whether the nurse it intends to send is competent with it.
| Device | What it is | What the agency has to manage |
|---|---|---|
| Peripheral intravenous catheter | A short catheter placed in a vein of the hand or arm, usually for the visit or a short course | The nurse’s insertion skill, site assessment at each use, and a plan when access cannot be obtained. |
| Midline catheter | A longer catheter placed in an arm vein whose tip stays in the peripheral circulation | Knowing it is not a central line, dressing and securement care, and whether policy allows the ordered therapy through it. |
| Peripherally inserted central catheter | A catheter placed through an arm vein with its tip in the central circulation | Dressing changes, flushing and locking, connector changes, and surveillance for occlusion and infection, on the schedule policy sets. |
| Tunneled central catheter | A central catheter tunneled under the skin before it enters the vein, used for long-term therapy | Long-term site care, repair and occlusion procedures, and patient teaching that lasts for years rather than weeks. |
| Implanted port | A reservoir placed under the skin and reached with a non-coring needle | Competency in accessing and de-accessing, needle change intervals under policy, and maintenance between cycles. |
The professional standard for this work is the Infusion Therapy Standards of Practice, published by the Infusion Nurses Society. The Society describes the Standards, now in their ninth edition, as setting expectations for safe, consistent infusion care across all patient populations and in any setting where infusion therapies are administered. An agency writes its policies and its competency checklists against the Standards, and updates both when a new edition is published.
Coding practice shows how central the device is to the business. The national coding standard for home infusion claims has separate codes for catheter care as a standalone service, for supplies used to clear or repair a catheter, and for insertion by a nurse of a peripherally inserted central catheter or a midline. Pharmacy contracts usually price these as separate services.
4. The referral and the governing order
A referral from a pharmacy is a packet: the patient, the address, the diagnosis, the drug, dose, route and frequency, the prescriber, the device, the delivery date and what the pharmacy wants back. The center of it is the prescriber’s order. The pharmacy dispenses against it and the nurse administers against it. Medicare’s rules for its home infusion benefit state the principle formally: the patient must be under the care of a physician, nurse practitioner or physician assistant, with a plan of care established by a physician that prescribes the type, amount and duration of services and is periodically reviewed.
Orders change, usually reaching the agency through the pharmacy, and the operating question is which order governs the next visit. A revised order is a new order. It has its own date, signature status and effective period, and it supersedes the earlier one from that point forward. It does not rewrite the past. A visit made last week was made under last week’s order, and the record has to keep saying so. An agency that edits the order in place can no longer show a pharmacy or a surveyor what the nurse was authorized to give on a particular day.
5. First doses and emergency preparedness
The first time a patient receives a drug carries a risk later doses do not: nobody yet knows how this patient will respond. Agencies and pharmacies therefore decide, by policy and by therapy, whether a first dose may be given at home, what has to be on hand and how long the nurse stays afterward. Some first doses are given in a clinic or an infusion suite for that reason, with later doses at home.
Preparedness for a severe reaction, including anaphylaxis, is an organizational duty rather than an individual one. It consists of an order or protocol from the prescriber for what the nurse may give in an emergency, the emergency medications and supplies present at the visit and in date, a nurse trained and assessed on the agency’s procedure, a means of calling emergency services, and a record afterward of what happened and who was told. The specifics belong to the prescriber’s order and the professional standards. Operationally, each element is evidence that is present or missing before the nurse leaves.
6. The nursing visit
A visit has a fixed anatomy, whatever the drug. The nurse confirms the patient’s identity and the order that governs today, checks the delivered drug against it, and assesses the patient and the access device. Premedications are given if ordered. The therapy is started and monitored as the order and policy require. The patient and caregiver are taught what they will do between visits. The device is secured or the needle removed, supplies are counted, and the patient signs.
CMS guidance on Medicare’s home infusion benefit lists what the teaching may cover: vascular access device maintenance, medication education and disease management, medication storage and patient safety, and self-monitoring. A pharmacy contract asks for the same content under different headings.
7. Documentation and the turnaround to the pharmacy
The nursing note is the agency’s product as much as the visit is. The pharmacy needs it to ship the next dose, to answer the prescriber, to satisfy its accreditor and, where it bills a plan for nursing, to support the claim. Each pharmacy states what it wants: its own form or the agency’s, which fields are mandatory, and how quickly the packet must arrive, commonly stated in hours or by the next business day.
A note has to be complete when it is signed, because one returned for a missing field delays the patient’s next shipment and the agency’s invoice together. And it has to be reviewed by a clinical lead before it leaves, because the pharmacy treats what it receives as the agency’s statement of what happened.
8. Who pays, and how
A home infusion visit can be paid for in several ways. The payer and program models page describes the general pattern; for this line the arrangements are these.
| Arrangement | Who pays the nursing agency | Unit of payment |
|---|---|---|
| Pharmacy contract | The pharmacy, by invoice | Per visit or by time, with travel and mileage terms |
| Commercial plan, per diem model | The pharmacy, or the plan if the agency is contracted | Per diem and drug to the pharmacy; nursing per visit and additional hour |
| Medicare Part B home infusion therapy services | Medicare, to a qualified supplier, on a professional claim | One payment per infusion drug administration calendar day |
| Medicare Part D drug | Not Medicare: Part D does not pay for nursing | Whatever other arrangement exists |
| Medicare home health | Medicare, to a certified home health agency | The 30-day home health payment period |
The pharmacy contract
The usual agreement pays a rate for a visit of up to a stated length and a further rate for each additional hour. It then deals with what a home visit costs that a clinic visit does not: travel time, mileage beyond a radius, visits that could not be completed, after-hours work, supplies the nurse provided, and laboratory draws or line-care visits priced on their own. It states the documentation terms, and often makes payment conditional on the note arriving within the stated window.
Commercial plans and the per diem
Commercial insurers generally pay for home infusion under the per diem model. The National Home Infusion Association’s coding standard defines the term: a per diem represents each day that a patient is provided access to a prescribed therapy, from the day the therapy is initiated to the day it is permanently discontinued. Each per diem code in the federal code set includes administrative services, professional pharmacy services, care coordination and all necessary supplies and equipment. The codes are the “S” codes of the Healthcare Common Procedure Coding System, of which the standard counts approximately 80 for home infusion.
Two things are deliberately left out of the per diem. Drugs are coded and paid separately. So are nursing visits: the standard states that the per diem codes specifically exclude nursing visits, and that nursing is coded with one code for a visit of up to two hours and another for each additional hour. That structure is the reason pharmacy contracts with nursing agencies look the way they do. The pharmacy is paid for nursing by the visit and by the hour, and it buys nursing on the same terms.
Medicare
Medicare’s coverage of home infusion is split across benefits. The pieces are these.
Part B, durable medical equipment. Medicare covers external infusion pumps as durable medical equipment under a national coverage determination, with the drugs necessary for the effective use of a covered pump. The pump, drug, supplies and dispensing are paid to an enrolled equipment supplier.
Part B, home infusion therapy services. Section 5012 of the 21st Century Cures Act created a separate benefit, in effect since January 1, 2021, for the professional side of the same therapy. It covers professional services including nursing under the plan of care, patient training and education not covered under the equipment benefit, and monitoring. It applies only to home infusion drugs: parenteral drugs and biologicals administered intravenously, or subcutaneously for an administration period of 15 minutes or more, in the home through a pump that is an item of durable medical equipment. Insulin pump systems and self-administered drugs are outside it.
Only a qualified home infusion therapy supplier can bill the benefit: a pharmacy, physician or other provider of services or supplier licensed by the state in which it furnishes items or services. It must ensure safe and effective provision of the therapy seven days a week and 24 hours a day, be accredited by an organization CMS has designated, and enroll in Medicare as a Part B supplier. It need not furnish the pump or drug. The requirements are in 42 CFR Part 486, Subpart I.
Payment is a single amount for each infusion drug administration calendar day, which CMS defines as a day on which home infusion therapy services are furnished by skilled professionals in the patient’s home on the day the drug is administered. CMS guidance is explicit that payment is made only on days the supplier is in the home; services on other days are bundled into it. There are three payment categories: category 1 for certain intravenous drugs such as antifungals and antivirals, inotropes, pain management and chelation drugs; category 2 for subcutaneous infusions such as subcutaneous immunotherapy; and category 3 for intravenous chemotherapy and other highly complex drugs and biologicals. Each has a billing code for an initial visit and one for subsequent visits. Visits are reported in 15-minute units, while payment is one unit per visit, an amount CMS describes as equal to five hours of infusion in a physician’s office. An initial visit may be billed only for a new patient or one whose last such visit was more than 60 days earlier.
Intravenous immune globulin at home. Section 4134 of the Consolidated Appropriations Act, 2023 added coverage, from January 1, 2024, of items and services for administering it at home to patients with primary immune deficiency disease.
Part D. CMS guidance gives antibiotics as an example of infusion drugs whose home administration the Part B home infusion benefit does not cover; such drugs may be covered under Part D. The industry association states the consequence: Part D may cover the drug, and the services, supplies, equipment and nursing are not covered.
Home health. For an eligible, homebound patient, nursing for those other infusion drugs can be covered under the Medicare home health benefit through a certified agency. For the pump drugs it is different. CMS guidance states that for dates of service on or after January 1, 2021 home infusion therapy services are excluded from the home health benefit. A home health agency that wants to provide and bill them enrolls as a qualified home infusion therapy supplier, and when a visit serves both purposes it separates the time and submits two claims.
9. Accreditation, licensure and the pharmacy’s standards
Accreditation. For Medicare’s home infusion benefit, accreditation is a condition of enrollment. CMS enrollment guidance lists the recognized accreditation organizations for home infusion therapy suppliers as The Joint Commission, URAC, the Accreditation Commission for Health Care, Community Health Accreditation Partner, the National Association of Boards of Pharmacy and The Compliance Team. Outside Medicare, accreditation is a commercial fact: accredited pharmacies have to show how they oversee contracted nursing, so they ask the agency for evidence. One of the recognized organizations offers a separate accreditation service for infusion nursing.
State licensure. States regulate this work through more than one door. The nurse holds a license from a board of nursing. The agency may need a license as a home health or home care organization, depending on how the state defines skilled services delivered at home. The pharmacy answers to a board of pharmacy. CMS enrollment guidance reflects the same pattern for Medicare: a supplier must be appropriately licensed in each state in which it provides services in patients’ homes, including across a state border. An agency entering a new state answers the licensing question for the organization, not only the nurse.
Pharmacy standards that reach the nurse. The pharmacy prepares sterile drugs under USP General Chapter <797>, Pharmaceutical Compounding, Sterile Preparations, whose current revision became official on November 1, 2023. USP states that administration, and preparation according to the manufacturer’s approved labeling, are outside the scope of the chapter. The nurse is therefore not a compounder. The standard still reaches the visit through the pharmacy’s label, which the nurse checks before anything is given.
10. Nurses, competency and geography
A license says a nurse may practice. It does not say the nurse can access an implanted port or teach parenteral nutrition. Competency in this line is specific to the therapy and the device, assessed and documented by the agency, and asked for by pharmacies before they send a patient. The roster is therefore a matrix: each nurse, therapy and device, with a date and an assessor, beside the license.
Geography multiplies the problem. A pharmacy ships across a region and asks one question: can you cover this patient in this town on this date. The answer depends on which competent nurse lives within practical reach. For agencies near a state line, the Nurse Licensure Compact matters. It allows a registered nurse or licensed practical or vocational nurse whose primary state of residence is a compact state to hold one multistate license and practice in other compact states, under the laws of the state where the patient is located. A patient in a state outside the compact needs a nurse licensed in that state.
Travel is a cost of production, and the contract may or may not pay for it. An agency that knows the drive before it accepts the referral can price it, decline it, or find a nearer nurse. How demand for a nurse in a particular place becomes a search for one is the subject of clinical demand meets workforce supply.
11. Invoicing the pharmacy
The invoice is the contract applied to the reviewed visit: the patient by the pharmacy’s identifier, the date, the service, time in and out, units beyond the base visit, mileage and travel where payable, and supplies. Many pharmacies will not process a line until the note has been received.
Three things have to be true for the invoice to be right. The visit happened and was documented. The documentation was reviewed. And the rate applied is the rate in the agreement in force on the date of service, not the rate someone remembers. The agency holds each of those facts, usually in three different places.
Where it breaks
What goes wrong when the work is spread across systems.
The referral typed three times
The packet arrives by fax or portal and is keyed into a schedule, a chart and a billing sheet. The three copies begin to differ the same day.
Last month’s order in the nurse’s hand
A revision reached the office and not the nurse, or replaced the earlier order so completely that nobody can tell which visits it applied to.
Licensed, and not shown competent
The schedule checks the license. The competency for this therapy and this device lives in a binder, and the pharmacy asks for it after the visit.
A note the pharmacy sends back
Each pharmacy wants different fields. An incomplete note delays the next shipment, restarts the turnaround clock and holds the invoice.
Rates from memory
The same visit is worth different amounts to different pharmacies, with different mileage rules. Typed from memory, the invoice is late and sometimes wrong.
What software has to do
Each failure above is a dependency between two steps recorded in different places. Software has to hold the dependencies, not only the steps. Against the six engines of one operating model, the work divides as follows.
| Engine | What it has to do for this line |
|---|---|
| Clinical | Hold each order and each revision as its own record and know which one governs a given date. Guide the note through verification, assessment, access device care, administration, monitoring, teaching and signatures, and compare what was given with what was ordered before the note is signed. Put clinical review between the visit and anything sent outside the agency. |
| Administration | Read the referral once and have a person confirm it. Schedule the visit against the drug delivery and the order’s frequency. Track each pharmacy’s turnaround clock from the end of the visit to receipt of the note, with an owner for every exception. |
| Revenue Cycle | Hold each pharmacy’s agreement as dated terms: base visit, additional time, travel, mileage, supplies. Price a reviewed visit from the terms in force on the date of service. Show every completed visit that has not reached an invoice, and why. Where a plan is billed, produce the professional claim with nursing coded by visit and additional hour. |
| Continuous Compliance | Treat each accreditation standard, state rule and agency policy as an obligation with evidence drawn from the record: competency before assignment, emergency supplies at a first dose, review before release, a signed plan of care. Judge a past visit by the rule and the order in force on its date. |
| Workforce | Keep the matrix of nurse by therapy by device, with license, compact status and expirations. Answer the coverage question from the patient’s address and the order, including the drive, before the referral is accepted. When no one on staff fits, carry the same requirement to a wider search. |
| Interoperability | Receive referrals and revisions the way each pharmacy sends them, return the note in the form it requires, and give the pharmacy a governed view of its own patients. Connect to the pharmacy’s system where it offers a connection, and to fax where it does not. |
One chain, shared with every other line
A patient, an order, a clinician, a visit, the evidence created, the obligation being satisfied and the money earned are not unrelated records. They are different views of the same operational event.
In home infusion nursing the order, the nurse’s competency, the visit, the reviewed note, the pharmacy’s terms and the invoice line are six views of one infusion. The same structure carries an agency’s other lines. A specialty pharmacy program adds program requirements to the same visit. An infusion suite adds a chair and removes the drive. Medicare home health replaces the pharmacy’s terms with a federal payment system. The patient, the clinician and the evidence are shared, which is why compliance and revenue can both be read from one record.

Questions
Home infusion nursing: common questions
What does a home infusion nursing agency do?
It sends nurses to patients’ homes to administer drugs that a home infusion or specialty pharmacy dispenses. The pharmacy supplies the drug, the supplies and the prescriber’s order. The agency assesses the patient, cares for the vascular access device, gives the therapy, teaches the patient, documents the visit and returns that documentation to the pharmacy.
Who pays a home infusion nursing agency?
Most often the pharmacy, under a contract that sets a rate per visit or by time, with terms for travel, mileage, supplies and documentation. Where the agency bills a health plan itself, commercial plans generally pay the pharmacy a per diem for services, supplies and equipment and pay for drugs and nursing visits separately.
Does Medicare pay for home infusion nursing?
Only in a narrow case. Since January 1, 2021, Medicare Part B has a home infusion therapy services benefit that pays an accredited, enrolled qualified home infusion therapy supplier for professional services on days a professional is in the home, and only for drugs given through a pump covered as durable medical equipment. Part D may cover other infusion drugs but does not pay for the nursing.
Why is a revised order treated as a new order?
Because every dose given has to be traceable to the order that authorized it. If a revision overwrites the earlier order, visits already completed appear to have been given under instructions that did not exist at the time. Keeping each revision as its own order, with one order governing at any moment, preserves that trace.
What is the professional standard for infusion nursing?
The Infusion Nurses Society publishes the Infusion Therapy Standards of Practice, now in its ninth edition, which the Society describes as setting expectations for infusion care across all patient populations and in any setting where infusion therapies are administered. Agencies write their policies, competencies and vascular access procedures against it.
Can a home health agency provide Medicare home infusion therapy services?
Under CMS guidance, home infusion therapy services for covered pump drugs are excluded from the Medicare home health benefit for dates of service from January 1, 2021. A home health agency that wants to furnish and bill them enrolls as a qualified home infusion therapy supplier. Infusion of drugs outside that definition can remain under the home health benefit for an eligible patient.
Which organizations accredit home infusion therapy suppliers for Medicare?
CMS enrollment guidance lists The Joint Commission, URAC, the Accreditation Commission for Health Care, Community Health Accreditation Partner, the National Association of Boards of Pharmacy and The Compliance Team as recognized accreditation organizations for home infusion therapy suppliers.
Why does general home health software fit home infusion nursing poorly?
Because the customer is usually a pharmacy under contract and each pharmacy has its own order format, documentation requirements, turnaround and rates. Software has to hold the pharmacy relationship next to the clinical record, since that relationship decides what is documented, what is returned and what the visit is worth.
