If you run a home-care agency that bills Medicaid for personal care, you have almost certainly heard about the 80/20 rule by now. It is one of the most consequential changes to the economics of home-based care in years, and it lands hardest on exactly the agencies with the least room to absorb it: the small and mid-size operators.
This guide explains what the rule actually requires, why it compresses margin so sharply, and where the margin levers still sit for an operator who cannot change federal policy but still has to make payroll.
What the 80/20 rule requires
The rule comes from the federal Ensuring Access to Medicaid Services Rule. Its central provision requires that at least 80 percent of Medicaid payments for homemaker, home health aide, and personal care services be spent on compensation for the direct care workers who actually deliver the care. Wages, benefits, and related worker compensation have to add up to at least four-fifths of what the program pays for those services.
That leaves roughly 20 percent of each payment to cover everything else the agency does. Not just profit. Everything: administrative staff, billing and collections, scheduling, nurse supervision, quality reporting, electronic visit verification, software, rent, insurance, and compliance with the growing list of federally mandated functions. Margin is whatever survives after all of that fits inside the 20 percent.
The intent behind the rule is defensible on its own terms. Direct care workers are underpaid, turnover is punishing, and policymakers wanted to push more of the Medicaid dollar to the front line. The difficulty is that the rule caps the non-labor side of the business without accounting for how much of that side is now federally required rather than optional.
Why it compresses margin so sharply
The reason the rule is so hard for smaller agencies is that the 20 percent has to stretch across costs that are mostly fixed and increasingly mandated. Electronic visit verification is not optional. Nurse supervision is not optional. Quality reporting is not optional. Those functions carry real administrative cost, and that cost does not shrink just because the payment formula changed.
The pressure is compounding, too. The 80/20 provision is arriving at the same time as broader Medicaid funding reductions and continued wage inflation for caregivers in a labor market where turnover runs high. An agency can face rate pressure on the top line, a wage floor pushing up the 80 percent, and a hard cap on the 20 percent, all at once. That is the environment a lot of operators are now planning around.
It is worth confirming the specifics for your own state. The payment-adequacy provision is being phased in over a multi-year timeline rather than switched on overnight, the exact effective date has continued to move through rulemaking and legal challenge, and states are implementing the details differently, sometimes with accommodations for smaller providers. Your state Medicaid agency is the authoritative source for where the timeline stands and how it applies to your service lines.
The margin lever you still control
Here is the part that matters for an operator. You cannot change the rule, the rate, or the wage floor. Those are set above you. But there is one margin lever that stays entirely in your hands, and it becomes more valuable, not less, as the cap tightens: collecting the revenue you already earned.
In most agencies, a meaningful slice of the revenue the agency was entitled to collect never actually gets collected. It slips out in small, quiet categories:
- Authorized but unbilled visits: care that was authorized and delivered but never made it onto a claim, usually because of a handoff gap between scheduling and billing.
- Denied claims that were never worked: denials that aged out of their appeal window before anyone corrected and resubmitted them.
- Lapsed authorizations: a renewal that slipped, so visits delivered afterward were denied for having no active authorization.
- Silent underpayments: claims that paid, but at the wrong rate, because a modifier or code was off. No denial, so nobody noticed.
- EVV documentation gaps: visits exposed to denial or later clawback because the electronic record did not line up with the claim.
None of this is money you are not owed. It is care your caregivers actually delivered, on authorizations that actually existed, that simply was not captured cleanly on the way to payment. In a normal-margin business, that leakage is annoying. In a 20-percent-cap business, it comes directly out of the part of the payment that keeps the lights on.
There is a second, quieter advantage. Recovered revenue is not new administrative spending. It does not add to the overhead side of the 80/20 equation. It is money you already earned, brought back onto the books. When almost every other lever either raises the 80 percent or is capped inside the 20 percent, collecting more of what you already earned is one of the few moves that improves the math without fighting the formula.
What to actually do about it
The practical first step is to find out how much is actually leaking in your own book, rather than assuming it is small. The most reliable way to do that is a structured look-back over a recent, closed period: pull your authorizations, delivered visits, and claims for the last 90 days and compare them at the line level. Look for authorizations with delivered visits but no matching claim, visits delivered just before an authorization expired, denials sitting past 60 days without a resubmission, and remittance lines that paid below the contracted rate.
That comparison will tell you more about where your margin is going than a monthly P&L will. Our guide on home care revenue recovery walks through how to run that 90-day review step by step, and where home-care margin leaks maps the five categories in detail. For the compliance side that the 20 percent now has to absorb, see EVV billing in home care and timely filing limits by payer, since the filing deadline is what turns a recoverable dollar into a permanent loss.
The agencies that come through the 80/20 transition in the best shape will not be the ones that found a way to cut supervision or skimp on compliance. They will be the ones that stopped leaving earned revenue on the table, because in a capped-margin world, that is the cleanest dollar left to go get.

Questions home-care owners ask about the 80/20 rule
What is the Medicaid 80/20 rule?
It comes from the federal Ensuring Access to Medicaid Services Rule and requires that at least 80 percent of Medicaid payments for homemaker, home health aide, and personal care services go to compensation for the direct care workers who deliver the service. That leaves roughly 20 percent to cover administration, billing, compliance, EVV, supervision, and margin.
When does the 80/20 rule take effect?
The payment-adequacy provision is being phased in over a multi-year timeline, and the exact compliance date has continued to move through federal rulemaking, state implementation, and legal and political challenges. Confirm the current effective date and any small-provider accommodations with your state Medicaid agency, because the details vary by state and are still changing.
Which services does the rule apply to?
It applies to Medicaid-funded homemaker, home health aide, and personal care services delivered through home and community-based services, rather than skilled home health billed to Medicare. Because implementation is set at the state level, the specific service lines and waivers covered can vary by state.
How can agencies protect margin under the rule?
You cannot change the rule, but you can stop leaving earned revenue uncollected. When only about 20 percent of each payment is available for everything other than direct-care wages, revenue lost to unbilled visits, aged-out denials, lapsed authorizations, and silent underpayments comes straight out of the thinnest part of the business. Recovering it is one of the few margin levers an agency still fully controls.
Does recovering lost revenue actually help under the rule?
Yes. Recovered revenue is money the agency already earned for care already delivered, brought back onto the books. It is not new overhead, so it does not add to the 20 percent side of the equation. In a capped-margin environment, collecting more of what you already earned is a more reliable way to protect the business than cutting overhead that is already stretched.
