What Changes Inside the Claim When CMS Moves to Molina
Part of our guide to the CMS Plan transition. Jessie Solognier, COO of Edwards Electronic Processing (EEP), on payer routing, remittances, electronic payment, and the patient-by-patient update every clinic has to make.
What’s happening
When the Florida CMS Plan moves to Molina, the claim itself barely changes. What changes is where it routes, how remittances arrive, and how you get paid electronically. There’s also manual work. Every CMS patient must be switched to the new plan in your practice system for October 1 dates of service and after.
For the transition overview and continuity-of-care detail, see our guide to the CMS Plan move to Molina.
What we know
Routing: Claims go to a different payer ID through a different EDI connection.
The claim itself: Largely unchanged. The same industry-standard rules apply.
Remittances: Molina begins issuing electronic remittance advice through its own vendor. Enrollment is required.
Payment: Confirm electronic funds transfer with Molina. Paper checks slow payments that will already be slower than usual.
Patient records: Each CMS patient’s plan changes from CMS Sunshine to CMS Molina for October 1 dates of service.
The interview
What actually changes inside a claim during this Florida transition to Molina?
Less than you might think. We’ll bill a different payer ID, and the claim routes through a different EDI connection, which is handled on the billing side. The claim itself follows the same industry-standard rules.
One caveat on the routing. Molina hasn’t published the CMS-specific payer ID yet, so that’s a confirm-with-your-clearinghouse item close to the cutover, not something to assume. The bigger changes sit around the claim, remittances, and payment enrollment, and those are worth their own answer.
What is your billing team doing differently right now?
We’ve added Molina to all of our billing databases and found the remittance vendor. We’re also building rules into our system that flag a claim headed to CMS Sunshine with a date of service after October 1, because that one is going to the wrong place. That matters because clinics have to update each patient’s plan from CMS Sunshine to CMS Molina. There are a lot of updates, and realistically, some will slip. At EEP, it’s a partnership. We put rules on our side, and when we catch one, we fix it.
On the clinic side, add CMS Molina as an insurance in your system now, before October. If you need help with that, let us know. Then the plan is already in place when your team starts updating charts, rather than being built under time pressure.
Where do claims for September visits go if they’re filed after October 1?
To Sunshine. Routing follows the date of service, not the date you submit. A September visit filed in November still goes to Sunshine, and appeals and corrections on those claims stay with Sunshine too. Only October 1 dates of service and later go to Molina.
Nothing in the guidance published so far extends timely filing on that trailing book, so work it on the normal clock.
Do remittances and direct deposit carry over, or start from scratch?
You set up payment for each plan from scratch. Molina issues remittances through its own payment vendor, so ERA enrollment is a separate step, distinct from contracting and credentialing. We know which vendor Molina uses, and we’re ready to send enrollment requests, intentionally timed. In our experience, going too early in a changeover just results in rejections stating that the payer doesn’t recognize the provider yet.
The same goes for payment itself. Most clients get funds straight to their bank account today, and that enrollment has to be set up again with Molina. Sometimes it rides along inside the credentialing packet, and sometimes it doesn’t, so ask specifically what yours covers. If those first payments arrive as paper checks, they’ll take longer, compounding the delay in a window when payments are likely to be slower anyway.
Is there anything that won’t be clear until October?
Some of it, yes. How secondary and coordination-of-benefits claims behave under Molina, and how remittances post in practice, are things we’ll learn as volume starts flowing. We’d rather say that plainly than guess. The pieces we can control, like routing, enrollment, and plan updates, are the ones worth finishing before the first claim goes out.
Claim-side setup
- Add CMS Molina as an insurance in your practice system before October.
- Plan the patient-by-patient switch from CMS Sunshine for October 1 dates of service.
- Confirm remittance enrollment is handled by your billing team or clearinghouse.
- Confirm electronic funds transfer with Molina so early payments don’t arrive as checks.
- Keep pre-October claims with Sunshine because earlier dates of service still route there.
Where EEP fits
EEP and TheraPlan focus on speech therapy, physical therapy, occupational therapy, and ABA therapy. Payer routing and remittance enrollment are plumbing a billing partner like EEP handles as a matter of course. TheraPlan lets a clinic add the new plan and work through patient updates in one place, so nothing gets tracked on the side.
