The Senate passed the reconciliation bill on July 1 by a 51 to 50 vote, the House passed it on July 3 by 218 to 214, and the President signed the One Big Beautiful Bill Act on July 4, 2025. Most of the coverage has been about tax policy. For a medical practice, the part that matters is buried in the Medicaid title, and it changes who will still have coverage when they arrive at the front desk in 2027.
We spent last week reading the Medicaid sections with the practices we support in mind, not the state budget offices. The short version: nothing changes for eligibility this year, several things change at the end of 2026, and the cost of a sloppy eligibility process goes up sharply after that. A practice that verifies coverage once a year and trusts the card on file is going to see denials it has never seen before.
This article covers what the law does, when each piece starts, and what we think a practice should change in its workflow before the first deadline arrives.
Key takeaways
- Nothing in the law changes Medicaid eligibility in 2025. The work requirement and six-month renewals for expansion adults arrive at the end of 2026, and the shorter retroactive coverage window on January 1, 2027.
- Coverage losses under work requirements have historically come from paperwork, not from people refusing to work, so the practice will see them as CO-27 and CO-31 denials on patients who believe they are covered.
- Per-visit 270/271 eligibility checks and a captured renewal date are the two workflow changes that matter, and both can be turned on this summer.
- The three-month retroactive coverage window still exists through 2026. Use it: register uninsured Medicaid-eligible patients as pending Medicaid and hold the claim.
- Provider tax limits starting in fiscal 2028 will pressure state Medicaid rates, which is a planning question for any practice with a meaningful Medicaid share.
What the law does to Medicaid
The Congressional Budget Office's June 29 estimate of the Senate text projected 11.8 million more people uninsured in 2034, most of them through Medicaid. The Senate dropped one Medicaid provision before the final vote, so the updated estimate for the enacted law, which CBO has not yet published, should land somewhat lower. Whatever the final figure, the coverage losses come from four mechanisms, each with its own effective date.
| Provision | Who it affects | Effective |
|---|---|---|
| Community engagement (work) requirement: 80 hours per month of work, community service, education or a combination | Expansion adults ages 19 to 64, with exemptions for groups such as pregnant women, parents of young children and people who are medically frail | States must implement by December 31, 2026; states can request an extension to the end of 2028 |
| Eligibility redeterminations every six months instead of every twelve | Expansion adults | Renewals after December 31, 2026 |
| Retroactive coverage cut from three months to one month for expansion adults and two months for other groups | New enrollees | Applications starting January 1, 2027 |
| Cost sharing of up to $35 per service, with exemptions for primary care and behavioral health | Expansion adults with income between 100 and 138 percent of the poverty level | October 1, 2028 |
| Provider tax limits: a freeze on new or increased taxes, and a phase-down of the allowable rate in expansion states from 6 percent toward 3.5 percent | States, and indirectly hospitals and the supplemental payment programs they fund | Phase-down begins in fiscal year 2028 |
The law also created a $50 billion Rural Health Transformation Program spread over five years, which states will apply for. It did not extend the enhanced ACA premium tax credits that expire at the end of 2025, and it tightens marketplace enrollment and verification in later years. Expect a second wave of coverage change in January 2026 from the marketplace side, separate from Medicaid.
Why this is an eligibility problem before it is a coverage problem
The people who lose Medicaid under a work requirement are not, in the main, people who fail to work. Georgia's experience since 2023 and Arkansas's in 2018 showed that most of the losses came from paperwork: people who did not receive the notice, did not understand the reporting portal, or missed a monthly deadline. Six-month redeterminations double the number of chances for a renewal packet to go astray.
For a practice, this shows up as a patient who was covered at the last visit, believes they are still covered, and is not. The claim comes back with CO-27 (expenses incurred after coverage terminated) or CO-31 (patient cannot be identified as our insured), and by then the visit is weeks old and the patient is hard to reach. Medicaid programs rarely allow you to bill the patient for a covered service, and the retroactive coverage window that used to rescue these situations shrinks to one month in 2027.
Put numbers on it. Suppose a practice has 1,500 active Medicaid patients in the expansion group, each averaging three visits a year at about $95 per visit. If six-month renewals push even 5 percent of them into a coverage gap they do not know about, and the practice catches none of it at check-in, that is 75 patients, roughly 225 visits and about $21,000 in claims that will deny and, under Medicaid rules, mostly cannot be billed to the patient. The same 75 patients checked at every visit produce a conversation at the desk and, often, a same-day renewal or a rescheduled visit. The figures are illustrative, but the shape is what we saw in every denial report during the 2023 to 2024 unwinding.
What to change in the workflow
Verify at every visit, not every year
Most practice management systems can run a 270/271 eligibility transaction in a batch two days before the appointment. Turn it on for every Medicaid patient, every visit, and read the response for more than active or inactive. The 271 usually carries the plan code, the managed care organization, the primary care assignment and sometimes the renewal or recertification date. Capture the MCO and the renewal date in the patient record. We covered the mechanics in our billing service description and in the eligibility workflow article on this site.
Track the renewal date as a field, not a memory
Once redeterminations happen twice a year, the renewal date becomes the single most useful data point at the front desk. A patient whose renewal falls in the next 45 days should hear about it at check-in. This is not the practice's job in any legal sense, but a thirty-second conversation is far cheaper than a denied claim and a patient who disappears from care.
Rebuild the self-pay script
Between now and 2027 the three-month retroactive window still exists, and practices should use it. When a Medicaid-eligible patient arrives without coverage, the visit should be registered as pending Medicaid, not as self-pay, and someone should hold the claim rather than write it off. After January 2027 the window closes faster, and the script has to change to same-day application assistance or a clear self-pay arrangement.
Watch your state, not the federal text
Every deadline in the table is a federal ceiling. States decide how to implement work requirement reporting, what their exemption process looks like, and whether to ask for the 2028 extension. Assign one person to read the state Medicaid agency's provider bulletins monthly. The practices that struggled most during the 2023 to 2024 unwinding were the ones who learned about state changes from denial codes.
The provider tax piece, in plain terms
Independent practices do not pay provider taxes, so it is tempting to skip this section. Do not. Provider taxes fund the state share of many supplemental payment programs, and the phase-down starting in fiscal 2028 will force expansion states to find money elsewhere or cut. The usual candidates are Medicaid fee schedule rates and managed care capitation. If Medicaid is more than 15 percent of your payer mix, the rate environment in 2028 to 2030 is a planning question for your practice, not just for the hospital down the road.
A timeline for the practice
- Summer 2025: Turn on per-visit eligibility for Medicaid. Add the renewal date field. Pull a report of your Medicaid patients by MCO so you know where the volume sits.
- Fall 2025: Train the front desk on the new marketplace enrollment season. Patients moving from Medicaid to marketplace plans in January will arrive with new cards and, often, deductibles they did not have before.
- 2026: Watch for your state's implementation plan for community engagement reporting. Decide whether the practice will offer any enrollment assistance or refer to a navigator.
- Late 2026: Expect the first work requirement terminations and the first six-month renewals. Review Medicaid denial codes weekly for two quarters.
- 2027 onward: New retroactive coverage limits apply. Rewrite the pending-Medicaid hold rule to match.
Questions we hear
Does this affect Medicare patients or dual eligibles?
The work requirement and six-month redeterminations are aimed at the expansion adult group, which is largely under 65 and not on Medicare. Dual eligibles are generally in other eligibility groups. The retroactive coverage change touches non-expansion groups too, with a two-month window rather than one.
Should we stop accepting Medicaid?
That is a business decision that depends on your payer mix and your community, and we would not make it on the strength of this law alone. What the law does argue for is running Medicaid like a commercial payer: eligibility every visit, denials worked by root cause, and a monthly look at the state bulletin. Practices that already do this will feel the change far less than practices that do not. If you want help setting up the eligibility rhythm, book a call with our team.
Our state never expanded Medicaid. Does any of this apply to us?
Less of it. The work requirement and the six-month renewals apply to the expansion adult group, which your state does not have. Three pieces still reach you: the retroactive coverage window for non-expansion groups drops from three months to two for applications from January 2027, the provider tax freeze applies in every state, and the marketplace changes in January 2026 will affect patients in the coverage gap who currently buy subsidized plans. The per-visit eligibility habit is still worth building; it is simply less urgent.
What to do this month
- Ask your practice management vendor to enable batch 270/271 eligibility for every Medicaid appointment, two business days ahead, and confirm the full 271 response is stored, not just the active flag.
- Add a renewal date field (or repurpose an existing custom field) in the patient record and start filling it from 271 responses and state portal lookups.
- Run a report of Medicaid patients by managed care organization and, as far as your system can tell them apart, by eligibility group.
- Write the pending-Medicaid hold rule down: who registers the patient as pending, how long the claim is held, and who checks for retroactive eligibility each week.
- Subscribe one named person to your state Medicaid agency's provider bulletin and put a fifteen-minute monthly review on the calendar.
