Medicaid has been through cycles of major change before, from the Affordable Care Act to the pandemic-era unwinding. H.R. 1 is the latest chapter, and it’s arriving in two waves. Eligibility rule changes tied to immigration status take effect October 1, 2026. Work requirements, more frequent renewals, and shorter windows for retroactive coverage follow on January 1, 2027, giving states a real window to get communications right before that volume hits. How clearly agencies communicate through both waves shapes whether members keep their coverage and whether caseworkers can keep up.

We’ve spent nearly 30 years supporting government and healthcare clients through this kind of transition. Here’s what we’ve learned about what communications need to get right, and some best practices that hold true across every major Medicaid shift we’ve supported.

Members need to understand what’s changing, and when

Every eligibility change starts with a simple question: does the person affected actually understand what’s happening to them? Members need plain-language explanations of upcoming eligibility, renewal, and CE changes, delivered through outreach materials that meet people where they are. Provider communications matter just as much, keeping referral and documentation processes moving smoothly as the rules shift underneath them.

Caseworkers and call centers need the same clarity, earlier

The information members need starts with the people answering their questions. Caseworkers and call center staff need clear, well-timed communication about new policies, procedures, and systems, well before renewal and eligibility volumes spike. Reference materials they can actually use under pressure often matter more than the training session itself.

Sustained communication carries a transition past go-live

A transition this size doesn’t end on the effective date. States need a communication plan that continues afterward: channels for feedback as issues surface, updates as guidance evolves, and a network of people inside the agency who keep reinforcing what’s changed long after the rollout.

Best practices we’ve seen work, transition after transition

• Start before the deadline forces your hand. The states that fare best begin outreach months ahead of an effective date, not in the weeks before it.
• Segment your audience. A single notice rarely reaches everyone effectively. Members affected by immigration-status changes, work requirements, or renewal timing each need messaging tailored to their situation.
• Repeat the message across channels. Mail, text, email, and phone outreach each catch a different slice of the population. Redundancy is a feature, not a waste of effort.
• Build feedback loops into every communication. Frontline staff who can flag confusing guidance or unexpected member questions early help agencies catch problems before they scale.
• Keep communicating after go-live. The messages that matter most are often the ones sent months later, reinforcing what changed and why it still applies.

How we support this work

For state Medicaid agencies: The transitions that go smoothly tend to share a pattern: member communication, caseworker readiness, and post-launch reinforcement get planned together from the start. If your team is thinking through how to sequence that work for H.R. 1, we’re glad to share what’s worked for other states.

For technology vendors: System go-lives succeed or stall based on how well caseworkers and members understand what’s changed underneath them. We partner with integrators and vendors on that communications piece, and we’re happy to compare notes on what a strong readiness plan looks like for your engagement.
