Here is a scenario that is about to get a lot more common. A patient who was covered by Medicaid last month walks in today. Your front desk has no reason to think anything has changed. The visit happens. The claim goes out. Weeks later it comes back denied, because coverage lapsed somewhere in between and nobody knew.

Medicaid eligibility is entering a period of real volatility. For practices that lean heavily on Medicaid populations, behavioral health, pediatrics, rural primary care, FQHCs, this is not a policy debate. It is an operational problem with a finite window to solve.

What Is Actually Changing

Two structural changes under the One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, are reshaping the Medicaid eligibility landscape:

• Work requirements are now active for the Medicaid expansion population (adults ages 19 to 64 covered under the ACA expansion). Affected enrollees must meet 80 hours per month of work, training, or community engagement to maintain coverage.
• Six-month redeterminations begin on December 31, 2026 for expansion adults subject to work requirements. Instead of the annual redetermination cycle most state Medicaid programs run today, these enrollees will have their eligibility rechecked every six months.

The Congressional Budget Office estimates 11.8 million Americans will lose Medicaid or CHIP coverage by 2034 as a result. Some analyses, factoring in interaction effects with marketplace subsidies and state implementation choices, project the total coverage loss closer to 16 million people, with significant variation between states.

For a given practice, the relevant question is not the national number. It is what percentage of your panel is in that population, and how often coverage is going to change for them.

Why the Old Eligibility Cadence Will Not Hold

Most practices today run an eligibility verification step at the time of scheduling. Some run a second check at intake. That cadence works when Medicaid eligibility is annually redetermined and reasonably stable. It does not work when coverage can lapse every six months due to a missed work-requirement reporting deadline, or change between one visit and the next.

The denial path is predictable. A patient is covered when you schedule the appointment in March. They miss their April work-requirement reporting. Their coverage terminates in May. The visit happens in June. The claim goes out, comes back denied weeks later, and now you are reconciling write-offs.

In a year when coverage is this fluid, the only protection is upstream verification. Knowing before the visit instead of after the denial is the difference between a clean claim and a write-off.

What a Stronger Workflow Looks Like

The workflow patterns that drive eligibility-related denials toward zero in this environment:

• Real-time eligibility verification at scheduling. The 270 request goes out the moment the appointment is booked, with results visible to scheduling staff in real time.
• Pre-visit recheck on a documented cadence. For Medicaid populations specifically, a 24 to 72 hour pre-visit recheck catches coverage changes that happened after scheduling.
• Re-verification at check-in. If anything looks different, a patient mentions a new card, a reminder letter from the state, anything, front-desk staff can trigger a real-time recheck before the patient leaves the lobby.
• Eligibility data inside the workflow staff already use. A separate portal that requires logging in is a portal that gets used inconsistently. Verification has to live where the rest of the work happens.
• Established-patient recheck cadence. For high-volume Medicaid practices, a monthly or pre-visit recheck across the established patient panel surfaces coverage changes proactively, not after a denial.

What to Track to Know If It Is Working

Three numbers tell you whether your eligibility workflow is keeping up with the new environment:

• Eligibility-related denial rate by payer. If this number is climbing for your Medicaid MCO payers, that is the workflow falling behind the volatility, not bad luck.
• Coverage-change discovery rate. How often is your team finding coverage changes BEFORE the visit versus after the denial? The pre-visit number should be climbing as your workflow tightens up.
• Write-off volume tied to eligibility-related denials missed in the pre-visit window. This is the dollar figure that tells you what coverage volatility is currently costing you.

How HSC Approaches This

Harris Secure Connect’s 270/271 eligibility verification is built for exactly this kind of environment. Real-time response. Comprehensive coverage data, not just a yes/no. Integrated into the systems your team already uses. And backed by 26 years of payer relationships that mean responses come back fast and reliably.

If you serve a Medicaid-heavy patient panel and your current eligibility verification is starting to feel like a step ahead of the denials, our team is happy to walk through what stronger infrastructure looks like in this environment.
