The second axis

Who pays, and under what rules.

A healthcare agency is described on two axes. One is the care it delivers. The other is who pays for it. They are often confused, and software that confuses them ends up as a separate product for every combination.

Two axes

What care is delivered, and who pays for it.

Rows are service lines. Columns are kinds of payer. A mark shows a pairing that agencies commonly work under; coverage in any particular case depends on the plan, the state and the patient.

Healthcare staffing is not on this grid: a staffing company is paid by the client organization that needs the clinician. Medicaid home and community-based services and VA community care each have their own page because the program itself shapes the work.

Medicare and home infusion. The Medicare mark on the home infusion row is specific to a benefit. Since January 1, 2021, Medicare Part B has paid a qualified home infusion therapy supplier for the professional services, including nursing, training and monitoring, that go with certain drugs given through a pump covered as durable medical equipment. CMS states that those services are excluded from the home health benefit, and that for other infused drugs the professional services at home may be covered under the home health benefit when the patient is eligible for it. Medicare Advantage plans are required to include Part B benefits and apply their own networks and authorization rules. Medicare does not pay for every infusion given at home. The Medicaid and VA marks are also conditional: state Medicaid programs must cover home health nursing, and whether and how each pays for home infusion nursing differs by state; the VA lists home infusion among the skilled home health care it purchases from contracted community agencies for veterans who are eligible for community care and meet the clinical criteria. Home infusion nursing, in full →

Read along a row and the point is plain. An infusion suite may be paid by a pharmacy, by Medicare, by a managed-care plan, by an insurer and by patients, all in the same week. Read down a column and it is equally plain: a Medicaid plan may be paying the same agency for skilled home health, private duty nursing and personal care.

The clinical work follows the row. The money follows the column. An agency that grows almost always grows along both.

Private payA service agreement with the person or familyAn invoiceAn hour, a shift or a visitWeekly or monthly, by card or bank payment

Each row is a summary. The rules behind it, with their sources and the dates they were read, are on the service-line pages linked in each section below.

A pharmacy under contract

The pharmacy dispenses the drug and is the agency’s customer. Its contract sets what a nursing visit is worth, commonly a flat amount for the first hours and an hourly rate after, with its own rules for travel, mileage, supplies and missed visits. Every pharmacy’s contract differs, and an agency serving several holds several sets of terms at once.

What it changes: the authority to visit is the pharmacy’s order, the bill is an invoice, and the pharmacy expects the nursing note back in its own form within a stated time. There is no adjudication, but there is a customer who checks every line against its own records.

Medicare

Original Medicare pays for home health by period of care and for hospice by the day, under federal payment systems whose rates and groupings are republished on a cycle. It does not approve visits one at a time. It requires that the patient be eligible, that a practitioner certify the need, that the standardized assessment be completed and that the agency meet the Conditions of Participation.

What it changes: payment depends on the assessment and the diagnosis as well as the visits; a notice is due at the start of care; the claim lists every visit while paying for the period; and the agency is surveyed against federal conditions. Operational events, such as a late start or a missed visit, have payment consequences while care is still under way.

How Medicare home health actually operates →   Hospice →

Medicare Advantage

A private plan administers the Medicare benefit for its members and sets its own authorization, rate and claim rules. An agency contracted with several plans works under several rulebooks for patients who are clinically alike.

What it changes: care is usually approved in advance for a number of visits and must be re-approved to continue; the plan, not Original Medicare, receives the claim; and payment is commonly per visit at a contracted rate. Checking which coverage is active at referral matters, because the same patient’s care is billed to an entirely different party depending on the answer. Hospice is the exception: when a plan member elects hospice, Original Medicare pays the hospice.

Medicaid and managed care

Medicaid is run by each state within federal rules, and most states deliver much of it through managed-care plans. Home and community-based services, private duty nursing and personal care are authorized in units or hours for a period, by service.

What it changes: there is no single national workflow. The service authorization, the billing code, the unit, the claim rules and the requirement to verify visits electronically are set by the state and often by the plan. An agency in one state under three plans may have three sets of rules for the same aide visit.

VA programs

When the VA cannot provide care itself, it may authorize a community provider to deliver it. The authorization names the services, the disciplines, the quantity and the period, and care outside those terms is not covered by it.

What it changes: the authorization is a set of lines by discipline, each with its own quantity and dates; continuing care requires a new authorization before the first one ends; and the approval of care and the document that permits billing for it are separate facts that software must be able to hold apart. Claims go through the VA’s contracted network or to the VA, in the form the service requires.

Commercial insurance

An employer-sponsored or individual health plan covers home care by its own policy. Coverage, limits and the patient’s share differ by plan. Long-term care insurance is a separate product that reimburses personal care or nursing once the policyholder meets the policy’s conditions.

What it changes: prior authorization is the insurer’s, by code and quantity; the bill is a professional or institutional claim sent through a clearinghouse; and the result is adjudicated by that insurer’s rules, with the patient often owing part.

Private pay

A person or family engages the agency directly under a service agreement that states the service, the rate, the schedule and the terms of payment.

What it changes: nobody adjudicates anything, and the customer reads every line. The record of each shift or visit has to be exact, the invoice has to match it, and payment, balance and refunds have to be handled as carefully as a claim.

One structure underneath

However different these look, each is the same sequence with different contents.

  1. The party
  2. What it authorized
  3. Its pricing rule
  4. Care delivered
  5. Billable lines
  6. Invoice or claim
  7. Payment and remittance
  8. Reconciliation

Paloma’s architecture therefore represents the relationship first: who the agreement is with, what it authorizes, how it prices and how it must be told. A pharmacy contract is one such relationship. Medicare, a managed-care plan, a VA network, an insurer and a private-pay family are the same idea with different terms. Rates, codes and rules are held as data with effective dates, so a change in a payer’s terms is a change in data and an older visit is still judged by the terms in force on its date.

Because billing reads the operating record, the same reviewed visit is priced under whichever agreement governs it, and an agency with a mixed payer base keeps one roster, one schedule, one compliance record and one set of books.

A patient changes payer

Coverage moves from one plan to another in the middle of care. The patient, the orders and the clinicians are unchanged; the authorization and the party being billed change from a date.

Two payers for one patient

A program pays for skilled visits while the family pays privately for additional hours. Each visit is billed under the agreement that governs it.

One clinician, several payers

The same nurse sees a pharmacy’s infusion patient in the morning and a program’s patient in the afternoon. Their file is credentialed once.

Questions

Payer and program models: common questions

What is the difference between a service line and a payer model?

A service line is the kind of care an agency delivers, such as home infusion nursing, home health, hospice or private duty. A payer or program model is who pays and under what rules, such as Medicare, a Medicaid plan, a VA program, a pharmacy contract or a family. One service line can be paid under several models, and one payer can fund several service lines.

Why should software keep the two apart?

Because clinical work follows the service line and billing follows the payer. Software that fuses them needs a separate product for every combination, and an agency with a mixed payer base ends up running several systems. Kept apart, one record can express the combinations an agency actually has.

What does a payer change, in practice?

Four things: what must be authorized before care and in what unit; what form the bill takes; the unit in which the service is reported; and the cycle on which it is submitted and paid. The clinical visit itself is largely the same visit.

Is VA community care a service line or a payer?

A payer and program. The VA authorizes and pays for care that a community provider delivers, and the care itself may be skilled home health, home infusion, personal care or hospice. It is given its own service-line page here because its authorization and billing rules shape so much of the work.

Is a pharmacy a payer?

For an independent infusion nursing agency, usually yes. The pharmacy is the customer under a contract, and it pays the agency for nursing visits at agreed rates. The pharmacy in turn bills the patient’s insurer for the drug and related services. The agency’s bill is an invoice, not a claim.

Where does healthcare staffing fit?

On neither payer column. A staffing company is paid by the client organization that needs the clinician, under a staffing agreement, usually by the hour or shift. The patient’s payer is the client’s concern. What staffing shares with every other line is the clinician’s file.

What is a contractual counterparty?

Whoever the agency has an agreement with about a service: a pharmacy, Medicare, a managed-care plan, a VA network, an insurer or a private-pay customer. Each has terms that decide what is authorized, documented, charged and paid, and each is represented in the same way.
