Quick Answer
Lytec itself will not stop working on September 1, 2026. What stops is the ability to submit claims through Optum, Change Healthcare, or RelayHealth from inside Lytec. Whether you need to take action depends on which version you are running. If you are on Lytec 2021 or higher, your software is already eMEDIX ready and no upgrade is needed. If you are on Lytec 2020 or earlier, an upgrade is required as part of the migration.
If you heard about the September 1, 2026 Optum deadline and immediately started worrying about your Lytec stop working, take a breath. Lytec is not going away, and your practice is not about to lose its software. What is changing on September 1 is more specific than that, and once you understand exactly what stops and what does not, the path forward is straightforward. Which version of Lytec you are running determines what that path looks like for your practice.
The Short Answer: Lytec Is Not Going Away
Lytec will continue to work normally after September 1, 2026. Scheduling, patient records, charge entry, reporting, all of it keeps running exactly as it does today.
What stops on September 1 is one specific function: the ability to transmit claims to payers through Optum, Change Healthcare, or RelayHealth. That is a clearinghouse connection, not a Lytec function. The software is fine. It is the connection to one particular clearinghouse that is being retired.
The fix is to migrate to Lytec EDI powered by eMEDIX, the clearinghouse purpose-built for Lytec and the only one CGM has certified as the supported path forward. Once that migration is complete, Lytec returns to full functionality, and in most cases runs better than before because Lytec EDI integrates more deeply with the software than the old Optum connection ever did.
What Is Actually Stopping on September 1, 2026?
Optum is making a back-end technical change to how its clearinghouse connects to practice management software. Starting September 1, 2026, the existing connection between Lytec and Optum, Change Healthcare, or RelayHealth will no longer function for claims submission.
This is an Optum-side requirement, not a Lytec issue. CGM, the company that makes Lytec, has confirmed to Optum that it will not build a new connection to support the old pathway. The supported replacement is eMEDIX, which CGM owns and has built specifically for Lytec and its companion products.
The practical impact of doing nothing is straightforward: claims stop transmitting to payers on September 1. Your software keeps running, but nothing goes out, which means no new payments coming in. The cash flow effect builds quietly at first, but compounds within a few weeks once the claims already in the pipeline have cleared and nothing new is behind them.

Does This Affect Me? It Depends on Your Version
Not every Lytec practice is in the same position heading into September 1. The first thing to figure out is which version you are running, because that determines whether you need a software upgrade as part of your migration or whether you can go straight to setting up Lytec EDI.
How to check your Lytec version: Open Lytec, click Help in the top menu, and select About Lytec. The version number is displayed there. If you have any trouble locating it, send us a screenshot and we will confirm it for you.
Once you know your version, Lytec version compatibility with eMEDIX comes down to one clear threshold:

I Am on Lytec 2021 or Higher. What Do I Need to Do?
Good news: your software is already eMEDIX ready. There is no need to upgrade Lytec or make any major changes to your system. The only step is to contract for Lytec EDI through AZCOMP and complete the migration setup before September 1.
Here is what that process looks like:
- AZCOMP sets up your Lytec EDI account, typically within one to two days of sign-up.
- You are scheduled with an AZCOMP implementation specialist within the first week.
- In a single session of about two hours, we configure your Lytec EDI connection, set up your eMEDIX receiver in Revenue Management, and walk your staff through the new workflows.
- After that session, you can begin submitting claims to commercial payers right away.
- Payer enrollments run in the background over the following weeks, with AZCOMP coordinating the process throughout.
Your total hands-on time is roughly that one two-hour session. The rest is mostly waiting for payer enrollments to process, and your existing Optum or Change Healthcare connection keeps handling claims in the meantime so there is no gap in your cash flow.
The most important thing practices in this group can do right now is start the process. Enrollment processing takes several weeks for some payers, and the earlier you begin, the more room every enrollment has to clear comfortably before September 1. Start today by scheduling your migration consultion.
I Am on Lytec 2020 or Earlier. What Does an Upgrade Involve?
First: do not let the word “upgrade” derail you. It is more involved than a simple setup, but it is a path AZCOMP has walked with many practices, and we will map out exactly what yours looks like before anything happens.
Practices on Lytec 2020 or earlier have typically not updated their software in five or more years. That means the upgrade may involve more than just a new software version. Depending on your current environment, there could be operating system requirements, SQL Server version considerations, or licensing updates needed to support the current version of Lytec alongside Lytec EDI. Every practice’s situation is a little different, which is why AZCOMP assesses your specific setup first.
A few things worth knowing before you start:
- The upgrade and the migration to Lytec EDI happen together as one coordinated process. You are not managing two separate projects.
- AZCOMP handles the technical work. Your staff’s involvement is largely the same two-hour implementation session that every migration involves.
- Many practices on older versions find the September 1 deadline is the push they needed to finally tackle an upgrade they had been putting off for years. The disruption of doing it now is far smaller than the disruption of missing the deadline.
- Your cash flow is protected throughout. The same payer-by-payer enrollment model applies: your existing connection keeps handling claims until each payer’s Lytec EDI enrollment is approved.
If you are on Lytec 2020 or earlier and have not yet started a conversation with AZCOMP, now is the time to do it. The upgrade adds steps and time, and September 1 is not moving.

What About My Cash Flow During the Switch?
Regardless of which version you are on, the migration is built to protect your cash flow from start to finish.
Your existing Optum, Change Healthcare, or RelayHealth connection keeps submitting claims and receiving payments until your Lytec EDI enrollment is approved for each individual payer. There is no point where claims stop and a payment gap opens up. Only once eMEDIX is fully ready for a given payer does the routing switch over for that payer, and not a moment before.
One Exception: Eligibility Cuts Over Right Away
Eligibility verification uses different routing than claims and remittance, and it switches to Lytec EDI immediately. This is why getting the Medicare eligibility enrollment form submitted early in the process is worth prioritizing. AZCOMP will walk you through it during your migration.
Why Trust AZCOMP With This Migration?
AZCOMP has been named CGM’s number 1 reseller in the United States for 21 consecutive years. That recognition comes from CGM itself, the maker of Lytec, based on sales, customer retention, and service quality. It is not a title we gave ourselves.
When Change Healthcare went down in the 2024 cybersecurity outage, AZCOMP migrated 220 practices and billing companies from Change Healthcare to eMEDIX in about four months, under genuine emergency conditions with no advance warning. The September 1, 2026 deadline has been announced well ahead of time. If we could handle 220 migrations in four months with no notice, a planned transition is entirely within our capacity.
Right now we support 555 active eMEDIX client businesses, hold a 4.9-star Google rating with more than 620 five-star reviews, and have served independent practices nationwide since 2000.
There is also a structural advantage worth mentioning: AZCOMP supports both Lytec and Lytec EDI under one roof. When something goes wrong at the intersection between your software and your clearinghouse, you call one number and one team owns the fix. You are never the one stuck in the middle between two separate vendors pointing fingers at each other.
Jenny Caraway, who manages billing for Speech Therapy Plus in Richmond, Texas, put it simply after her migration: “We didn’t even have to do a whole lot. AZCOMP just took over to take care of all those system setups. The transition was actually really, really smooth.”
Frequently Asked Questions

Will my Lytec stop working on September 1, 2026?
No. Lytec itself will continue to work normally after September 1, 2026. You can still see patients, enter charges, and run reports. What stops is the ability to submit claims through Optum, Change Healthcare, or RelayHealth from inside Lytec. Once you migrate to Lytec EDI powered by eMEDIX, Lytec returns to full functionality.
How do I check which version of Lytec I am running?
Open Lytec, click Help in the top menu, and select About Lytec. The version number is displayed there. If you have any trouble locating it, send us a screenshot and we will confirm it for you.
Do I need to upgrade Lytec to use eMEDIX?
It depends on your version. If you are on Lytec 2021 or higher, your software is already eMEDIX ready and no upgrade is needed. You just need to set up Lytec EDI through AZCOMP. If you are on Lytec 2020 or earlier, you will need to upgrade to a current version as part of your migration.
I am on Lytec 2020. What does upgrading actually involve?
An upgrade from Lytec 2020 or earlier typically involves more than a simple software update. Depending on your setup, there may be operating system, SQL Server, or licensing items to address alongside the software itself. AZCOMP will assess your specific environment and map out exactly what your upgrade path looks like before anything happens. The upgrade and the Lytec EDI migration happen together as one coordinated process.
How long does the migration take if I am already on Lytec 2021 or higher?
The end-to-end migration averages about six weeks, but most of that time is spent waiting for payer enrollments to process rather than on active setup work. Your hands-on time is roughly one two-hour implementation session. After that session, you can begin submitting claims to commercial payers right away.
What happens if September 1 passes and I have not migrated yet?
Your claims will stop submitting through Optum, Change Healthcare, or RelayHealth, and your practice will begin accumulating unbilled days. The financial impact builds quickly. AZCOMP will still help practices that come to us after September 1, but every additional week of delay is another week of cash flow disruption. The right move is to start now while you still have lead time.
