The CMS Access Rule: 5 new requirements that could transform HCBS if they survive

In April 2024, the Centers for Medicare and Medicaid Services published a rule that does something the home and community based services system has never had to do. It makes states show their work. Not eventually, not in principle, on specific dates, in public, with numbers attached. Whether any of it survives to 2030 is a genuinely open question. What you can do about it in the meantime is not.

What the rule actually is

The formal name is the Ensuring Access to Medicaid Services final rule, CMS-2442-F. Everybody calls it the Access Rule. It was published in April 2024 and it applies to home and community based services across the country, including the waivers your adult child depends on.

The rule does five things that matter to a family. It forces states to publish what they pay. It forces them to run a grievance process. It forces them to prove they are reassessing people annually. It forces them to report their waiting lists honestly. And eventually it forces most of the service dollar to reach the person doing the work.

Every one of those is a disclosure requirement dressed up as a payment rule. That is not a criticism. Disclosure is how families get leverage, because you cannot appeal a number you have never been allowed to see.

The five requirements, with their dates

One, rate transparency, July 1, 2026. States must publish all fee-for-service Medicaid fee schedule payment rates on a publicly available and accessible website, and must compare certain categories to Medicare rates every two years.

Two, the grievance system, July 9, 2026. States must establish a process for fee-for-service beneficiaries to file grievances about HCBS, with resolution inside 90 days. If your adult child receives services outside managed care, this is your complaint route and it now has a clock on it.

Three, person-centered plan reassessments, July 9, 2027. States must document that at least 90% of beneficiaries enrolled in HCBS for a year or more received an annual reassessment. Ninety percent, documented, reported.

Four, waiting list and timeliness reporting, July 9, 2027. States must disclose whether they maintain waiting lists, how many people are on them, the average time from enrollment to services, and the average time from service approval to the service actually starting.

That last measure is the one I would put on a billboard. Approval-to-initiation is the gap every family lives in and no state has ever had to report. It is the difference between a service existing on paper and a person showing up at your door.

Five, the 80/20 compensation rule, July 9, 2030. At least 80% of Medicaid payments for homemaker, home health aide, and personal care services must be spent on compensation for direct care workers. States report readiness three years out, actual percentages four years out, and must comply at six years.

Incident management runs alongside all of it: data tracking by July 9, 2027 and an electronic system by July 9, 2029. Quality measure reporting starts July 9, 2028 and repeats every two years.

Why the 80/20 rule is contested, and what I think

The compensation pass-through is the provision that generated the fight, and the objections are not frivolous.

Providers argue that an 80% floor on compensation ignores real operating costs. Training, supervision, scheduling, background checks, workers compensation, and the administrative machinery that keeps a service running are not luxuries. Rural providers with thin margins argue the rule could close them, which would leave families with a compliant payment structure and nobody to deliver the service.

Those are real arguments and I am not going to pretend otherwise. Here is where I land anyway.

For twenty years the answer to “why can nobody staff this shift” has been that Medicaid does not pay enough. That may be entirely true. It has also been unfalsifiable, because nobody had to disclose what share of the payment reached the worker. A rule that makes the pass-through visible does not fix the wage. It makes the wage argument checkable, which is the necessary first step to fixing it.

What this does not do

It does not create a service. It does not shorten a waiting list. It does not raise a rate. Nothing in the Access Rule requires any state to pay more for anything.

It requires states to say what they pay, prove they are reassessing people, count who is waiting, and eventually show where the money went. That is it.

Which means the rule is worth exactly as much as the use families make of it. A published rate schedule that nobody reads changes nothing. A published rate schedule that four hundred parents cite in four hundred appeals changes the politics of the next rate hearing.

That is not a rousing conclusion. It is the accurate one.

Your practical next steps

This month. Find your state’s published fee-for-service rate schedule. The publication requirement took effect July 1, 2026. Print the rate for every service your adult child receives and put it in the binder.

Next time a service goes undelivered. If your adult child is in fee-for-service HCBS, file a grievance and reference the 90-day resolution requirement by name. Put it in writing. Keep the copy.

In 2027. Ask your state for its waiting list report and its approval-to-initiation figures. If your county’s number is worse than the state average, you have found a specific, documented, official disparity, which is the single most useful thing an advocate can carry into a legislative office.

Before 2030. Watch whether the 80/20 provision is delayed or narrowed, and say something in public if it is. Rules with long runways get quietly shortened by people who assume nobody is tracking the calendar. Track the calendar.
