Important Notice for Affected Microwize Clients
2026 Optum Electronic Submission Changes
Practices using Relay Health, Optum, Change Healthcare, Microwize Direct for electronic claims submission or real-time eligibility services need to transition to a new claims submission path before September 1, 2026.
Microwize is here to help you evaluate your options, determine upgrade requirements, and complete the transition before the deadline.
KEY DATES
September 1st, 2026
Electronic claims will no longer be submitted, and eligibility verification will stop working for affected practices. There is no grace period.
2028
ANSI 60/20 federal mandate takes effect, introducing new claims submission requirements.

Why is this happening?
What's Changing And How It Affects Your Practice.
Optum Is Changing Their System
Optum is requiring all connected software vendors to adopt a new technical format called ECG2. Every system connected to Optum must update before September 1, 2026 — or lose connectivity.
CGM Is Recommending eMEDIX
CGM (the company behind MEDISOFT and LYTEC) is recommending affected practices transition to eMEDIX, its fully supported clearinghouse solution. eMEDIX is already built into MEDISOFT and LYTEC and is designed to support electronic claims submission and eligibility transactions moving forward.
For practices affected by the Optum changes, eMEDIX provides a supported path with enrollment tools, training resources, and ongoing support from both CGM and Microwize.
September 1st Impact
Without action, practices using Optum-connected channels will lose access to claims submission and eligibility verification services on September 1. This is a hard cutoff with no grace period. Claims will stop going out, eligibility checks will fail, and practices may experience disruptions to both revenue cycle and front-office operations.
What this means for your practice
The upcoming changes originate with Optum and will impact certain claims submission and eligibility workflows. To help practices maintain uninterrupted operations, CGM is recommending eMEDIX as the supported path forward for affected MEDISOFT and LYTEC users.
Microwize is available to help practices evaluate their options, understand any upgrade requirements, and navigate the transition process.
Is my Practice Affected?
Are You Using Any of These?
If your practice uses any of the following channels to submit electronic claims or check eligibility, you are affected and need to take action before September 1.
If you use any of the above
You must transition to a new claims path before September 1. Claims will stop being submitted if you do not act. There is no grace period, the cutoff is hard and confirmed by both Optum and CGM.
If you’re already on eMedix
You’re all set. This change does not affect practices already submitting claims through eMedix. No action is required on your end.
Why Microwize Recommends eMEDIX
Before choosing your path, here’s what makes eMEDIX the right choice for most practices — and why it’s the only option Microwize fully supports.
- Fully supported by CGM and Microwize
- No custom development required
- Built directly into MEDISOFT and LYTEC
- Supported for future industry changes including ANSI 60/20
- Designed to minimize claims disruption during transition
The crosswalk advantage — claims don’t stop during the switch
CGM has built a crosswalk specifically for this transition. The moment you are set up on eMedix, your claims begin routing immediately — even before payer enrollment is complete. Claims continue going out through Change Healthcare in the background until enrollment finishes. Little to no downtime for your practice.
Your Next Steps
Find Your Transition Path
Your next steps depend on which software version you’re currently on. Check below to see exactly what your practice needs to do.
READY TO START
Medisoft v24+ / Lytec 2020+
You’re ready to begin eMedix enrollment.
NEED UPGRADE FIRST
Medisoft v23 or lower / Lytec 2019 or older.
You must upgrade your software to start eMEDIX enrollment.
Key Dates & Enrollment Timeline
Don't Wait Until August
Starting in August is almost certainly too late for Medicare practices. Payer enrollment takes 10 to 15 business days, and practices that start too late won’t be fully enrolled before September 1st.
Medicare enrollments take longer — plan ahead
If your practice bills Medicare, payer enrollment through eMEDIX typically takes 10 to 15 business days. This is normal, but it means you may need to start earlier than you think. Starting in August is almost certainly too late for Medicare practices.
Preparing for Future Industry Changes
Why a Supported Ecosystem Matters
September 1st is the immediate deadline, but it’s not the last change coming.
Here’s the broader context your practice should be aware of.
Right Now: September 1st, 2026
The Optum ECG2 change is the immediate problem. Practices not on eMEDIX by September 1 lose claims access. This is solvable — but only if you act now.
Coming Soon: ANSI 60/20 in 2028
The federal government is mandating a new claims file format in 2028. It requires deep changes to both the software and how EDI files are structured. This affects every practice in the country, not just Optum users.
Why It Matters Now
ANSI 60/20 will require significant software and EDI updates. Working with a supported ecosystem helps ensure your practice remains prepared for future industry changes.
2028: ANSI X12 60/20: A Government-Mandated Claims Format Change
ANSI 60/20 will require significant changes to how claims files are built and transmitted. Working within a supported ecosystem — where your software vendor is actively preparing for these changes — helps ensure your practice remains ready for future industry requirements.
Compare Your Options
eMEDIX vs. Choosing Another Clearinghouse
You have a choice, but the level of support your practice receives depends entirely on which path you take.
Move to eMEDIX (Recommended)
eMedix is built into Medisoft and Lytec. Microwize guides you through the entire process — enrollment, training, and testing. Your claims keep going out during the switch thanks to CGM’s crosswalk.
✓ Fully supported by CGM and Microwize✓ Claims continue routing during migration — no downtime
✓ EZ-ENROLL tools included
✓ Training provided by Microwize
✓ Eligibility stays uninterrupted
✓ Ready for 2028 ANSI 60/20 mandate
Choose Another Clearinghouse
You may choose a different clearinghouse. However, CGM is not updating Revenue Management to support any other format, meaning there is no automated claims flow. Your team would be managing a largely manual process.
—Revenue Management setup only
—No automated claims workflow
—You manage all enrollment directly
—No training provided by Microwize
—No custom configurations supported
—2028 ANSI compliance not guaranteed
