You may see this same service written as Optum EDI, OptumEDI, Change EDI, Change Healthcare EDI, or RelayHealth EDI. Whichever name appears on your statements, your contract, or inside your software, it is the same connection, and the September 1, 2026 deadline and the fix are identical.
Answer three quick questions to find out exactly where you stand.
Not sure? Open your software, click Help in the top menu, then About Medisoft or About Lytec. The version number is shown there. Send us a screenshot and we will confirm it for you.
It comes down to which version you are running. Use the table below, or send us a screenshot of your version and we will confirm it for you.
On a version that needs upgrading? You are not alone, and it is not as daunting as it sounds. Practices in this group often have not updated in five or more years, so beyond the software itself there may be operating system, SQL Server, or licensing items to bring current. AZCOMP will map out exactly what your specific upgrade path looks like before anything happens, so there are no surprises. Many practices find the September 1 deadline is the nudge they needed to finally tackle an upgrade they had been putting off.
On September 1, 2026, your ability to send claims through Optum, Change Healthcare, or RelayHealth stops. Here is what that does and does not mean.
Your Medisoft or Lytec keeps working. You can still see patients, enter charges, and run reports. What stops is claim submission: claims no longer transmit to payers through the old connection, so nothing goes out and nothing new comes back in.
That is a cash flow problem, and it builds quietly. Everything looks normal at first, which makes it easy to underestimate. But every day claims are not going out is a day of future payments that disappears, and for most practices a short interruption becomes a real revenue gap a few weeks later, once those claims would have been paid.
The good news: this is entirely avoidable. Once you migrate to eMEDIX, claims flow again, often through a workflow that runs better than before, because eMEDIX integrates with Medisoft and Lytec more deeply than the old connection ever did. The practices that come through this cleanly are simply the ones that start early.
eMEDIX is the medical claims clearinghouse purpose-built for Medisoft and Lytec, the service that sits between your software and the insurance payers to handle claim submission, payment posting, eligibility checks, and denials. As the integrated EDI solution for each platform, it is also known as Medisoft EDI and Lytec EDI, powered by eMEDIX.
Why is it the replacement? Because CGM, the same company that makes your software, built eMEDIX for Medisoft and Lytec specifically, which is exactly why CGM chose it as the path forward when the old Optum connection was retired. A few things set it apart:
With other clearinghouses, your biller leaves Medisoft or Lytec, logs into a separate website, and copies data back and forth. With eMEDIX, claims, remittance, eligibility, claim status, and reporting all happen right inside your software. No separate logins, no exporting batch files, no re-typing what is already in your system.
When something breaks at the seam between the two, most practices get bounced between vendors. With eMEDIX from AZCOMP, you call one number, and one team owns the fix.
eMEDIX posts a 99% clean claims rate, so the vast majority of claims are accepted on first submission, which means faster payment and far less rework. It handles every major claim type (professional, institutional, dental, workers' compensation, and auto accident) and submits secondary claims electronically, something several competing clearinghouses cannot do with Medisoft or Lytec.
There is no point where your claims stop and your payments dry up.
Your current Optum, Change, or RelayHealth connection keeps submitting claims and receiving payments until your eMEDIX enrollment is approved for each individual payer. Only then does that payer switch over, so there is no gap.
Enrollments take time, and some payers approve faster than others. For any payer not yet approved, claims keep routing through your existing connection during the transition. Your claims and remittance never experience an interruption.
Eligibility verification uses different routing and switches to eMEDIX immediately, which is why eligibility-related enrollment, including the Medicare eligibility form, is the one piece worth handling early.
There is no cash flow cliff on September 1. But the longer you wait to start, the more enrollment work compresses into a tight window right before the deadline. Starting now simply gives every enrollment room to clear comfortably.
Because no one in the country has done this longer, or more, than we have. AZCOMP has been named CGM’s #1 reseller in the United States for 21 consecutive years. That recognition is awarded by CGM itself, the maker of Medisoft and Lytec, based on sales, customer retention, and service quality. It is not a title we gave ourselves, and no other reseller in the Medisoft and Lytec channel has matched it.
When Change Healthcare went down in the 2024 cybersecurity outage, practices lost their clearinghouse overnight, with no warning and no lead time. AZCOMP migrated 220 practices and billing companies to eMEDIX in about four months, during a genuine emergency. The September 1, 2026 deadline is the same kind of move, except this time it has been announced well in advance. If we could move 220 practices in four months with no notice, we can absolutely handle a transition that everyone can see coming.
That experience is the whole point. We are not figuring out the Optum-to-eMEDIX path for the first time on your account. We have run it at scale, we know where the friction is, and we have built our process around protecting your cash flow while it happens.

Once you are signed up, AZCOMP creates your eMEDIX account and prepares your implementation. (Days 1 to 2, and we are working to bring this down to 24 hours.)
You are paired with an AZCOMP implementation specialist who will handle the setup with you. (Days 3 to 7.)
In a single session of about two hours, we configure Medisoft or Lytec, set up your eMEDIX connection in Revenue Management, and walk your staff through the workflows. As soon as this session is done, you can begin submitting claims to commercial payers that do not require their own enrollment.
Some payers approve in days, others take a few weeks. This is the part that takes time, and it is also the part you mostly wait on rather than work on. AZCOMP coordinates these enrollments with you, provides the forms, walks you through what each one needs, reminds you when items are pending, and stays with it through approval. (Weeks 1 to 6, running in parallel.)
As each payer's enrollment is approved, that payer switches to eMEDIX. Until then, your existing connection keeps handling those claims, so there is never a gap. When the last enrollment clears, you are fully migrated.
You are not stuck, and you are not the first. AZCOMP regularly takes on practices in exactly this position. Every year, roughly fifty practices come to us because their original VAR closed, got acquired, or simply went quiet, and we have a well-worn process for adopting them.
If that is you, here is the reassuring part: the Optum deadline and an absent VAR are the same conversation, solved in one move. When you come to AZCOMP, we:
You do not need to have been an AZCOMP customer before. Most of our clients found us from somewhere else, and many of them came to us in exactly this situation. Becoming an AZCOMP customer and migrating to eMEDIX happen together, as one step.
The deadline is forcing a lot of these conversations to happen sooner than they otherwise would have. That is not a bad thing. It is a good reason to finally get back onto solid ground with a partner who answers the phone.
Partly, and less than Medisoft and Lytec users. Here is the short version:
If you need eligibility, you can run it through the eMEDIX website directly. Longer term, CGM recommends Practice Partner practices consider moving to Aprima, the actively developed CGM EHR, and another option is to use Medisoft or Lytec as your back end. There is no single right answer for every practice, which is exactly the kind of thing a short call sorts out.
On September 1, 2026, Optum is making a back-end technical change to how its clearinghouse connects to medical practice software. Practices submitting claims through Optum, Change Healthcare, or RelayHealth from Medisoft will not be able to submit claims after that date unless they have migrated to a supported clearinghouse. CGM, the company that makes Medisoft, will not support the old Optum connection going forward. The path forward is to migrate to eMEDIX.
September 1, 2026 is the date Optum is implementing a back-end technical change to how its clearinghouse connects to medical practice software. If your Lytec practice currently sends claims through Optum, Change Healthcare, or RelayHealth, those claims will stop transmitting on that date unless you’ve moved to a supported clearinghouse. The old Optum connection is being retired, and CGM, the company behind Lytec, will not support it going forward. The path forward for Lytec practices is to migrate to eMEDIX.
On September 1, 2026, Optum is making a back-end technical change that ends its clearinghouse connection to Medisoft (and Lytec). If your Medisoft practice currently submits claims through Optum, Change Healthcare, or RelayHealth (all the same clearinghouse under different names), those claims will stop transmitting after September 1st unless you’ve moved to a supported clearinghouse first. Medisoft itself keeps working normally: you can still see patients, enter charges, and run reports. What stops is claims going out through the old connection. CGM, the company behind Medisoft, has confirmed eMEDIX as the supported path forward, and AZCOMP can migrate your practice with no gap in your claims or cash flow.
Yes. They are all the same clearinghouse service under different names from different eras. RelayHealth was the original brand, which became Change Healthcare, which was later acquired by Optum (part of UnitedHealth Group). If your practice uses any of these names for its clearinghouse, you are affected by the September 1, 2026 deadline.
Yes. If you’re on Medisoft and your clearinghouse is RelayHealth (also known as Optum or Change Healthcare, all the same service), you’ll need to move to a supported clearinghouse before September 1, 2026, or your claims will stop transmitting. The path forward is eMEDIX, the clearinghouse CGM built specifically for Medisoft. AZCOMP can handle the migration with no gap in your claims or cash flow. You’re not alone in this, CGM estimates thousands of practices are in the same position.
Yes, you do. Change Healthcare, Optum, and RelayHealth are three names for the same clearinghouse, and the connection between that clearinghouse and Lytec is going away on September 1, 2026. After that date, claims submitted through it will no longer transmit. To keep your billing running, you’ll need to migrate to a supported clearinghouse before then. For Lytec practices, that’s eMEDIX, the clearinghouse CGM built and maintains specifically for Lytec. AZCOMP handles the full migration with no interruption to your claims or your cash flow, and you’re in good company doing it. CGM estimates thousands of practices are making the same move right now.
No. Medisoft itself will keep working normally. You can still see patients, enter charges, and run reports. What stops is the ability to send claims through Optum, Change, or RelayHealth from inside Medisoft. Once you migrate to eMEDIX, Medisoft returns to full functionality, and in many cases works better than before, because eMEDIX integrates with Medisoft more deeply than the old connection did.
No. Lytec itself will keep working normally. You can still see patients, enter charges, and run reports. What stops is the ability to send claims through Optum, Change, or RelayHealth from inside Lytec. Once you migrate to eMEDIX, Lytec returns to full functionality, and in many cases works better than before, because eMEDIX integrates with Lytec more deeply than the old connection did.
Your software keeps working, but your claims stop going out. Medisoft and Lytec will still open, still let you see patients, still let you enter charges and run reports. What stops is the connection between your software and Optum (also known as Change Healthcare or RelayHealth), which means claims no longer transmit to payers through that route. Nothing new gets submitted, and nothing new comes back in.
The trouble is that the impact builds quietly. Everything looks normal for the first few days, which makes it easy to underestimate. But every day claims aren’t going out is a day of future payments that disappears, and for most practices a short interruption turns into a real revenue gap a few weeks later, when those claims would have been paid.
The good news is that this is entirely avoidable, and AZCOMP can still help even if September 1 has already passed. The sooner you start, the smaller the disruption. Practices that come to us after the deadline still get migrated to eMEDIX, they just lose some billing days in the process. Practices that start now won’t lose any billing days.
Yes. This isn’t a marketing tactic or a vendor scare, it’s a back-end technical change Optum is making to how its clearinghouse connects to medical practice software. CGM, the company that makes Medisoft and Lytec, has confirmed the September 1, 2026 date and has told Optum directly that it will not support the old connection after that point. The same change applies whether your contract is labeled Optum, Change Healthcare, or RelayHealth, which are all the same clearinghouse under different names.
It’s reasonable to be skeptical. Software deadlines do sometimes move, and Optum has not been the most reliable communicator throughout this rollout. Some practices got direct letters from Optum, some didn’t, and Optum has acknowledged its own customer list isn’t clean. But CGM and Optum have already agreed to the technical handoff, and the engineering work to retire the old connection is in motion on both sides. Treat September 1 as firm and plan accordingly.
eMEDIX is a medical claims clearinghouse purpose-built for Medisoft and Lytec. It is owned by CGM, the same company that makes Medisoft and Lytec, and it is the integrated EDI solution for each platform, also known as Medisoft EDI and Lytec EDI. Claims submission, electronic remittance, eligibility verification, claim status, and reporting all happen inside Medisoft or Lytec rather than through a separate external portal.

It depends on your version. If you are on Medisoft 24 or higher, your software is already set up to integrate with eMEDIX, and no upgrade is needed. You just need to set up eMEDIX through AZCOMP. If you are on Medisoft 23 or earlier, you will need to upgrade to a current version as part of the migration.
It depends on your version. If you are on Lytec 2020 or higher, your software is already set up to integrate with eMEDIX, and no upgrade is needed. You just need to set up eMEDIX through AZCOMP. If you are on Lytec 2019 or earlier, you will need to upgrade to a current version as part of the migration.
The end-to-end migration averages about six weeks, but most of that time is spent waiting for payer enrollments to process, not on active setup work. Your hands-on time is roughly one two-hour implementation session, after which you can begin submitting claims to commercial payers that do not require their own enrollment. You do not have to wait until every enrollment is finished to start using eMEDIX.
No. AZCOMP coordinates the enrollment process with you. We provide the forms, walk you through what each one needs, remind you when items are pending, and stay engaged through approval. Some enrollments require you to sign personally or create your own login, because those credentials must be in your name, but you are not left to figure it out alone.
It is a recently introduced CMS requirement, not something specific to AZCOMP or eMEDIX. To submit claims, eligibility, or remittance through Medicare, every provider NPI must have a current attestation document on file. The form is straightforward and available through CGM’s Easy Enroll tool, and AZCOMP will walk you through it during your migration. Because Medicare claims will not process without it, it is one of the few items worth handling early.
Some training is needed, because eMEDIX has a different interface than your old clearinghouse, but the learning curve is shorter than you might expect. Most of the workflow happens inside Medisoft or Lytec, which your staff already uses every day. The new patterns are mostly in the eMEDIX portal, for things like the worklist, timely filing letters, and claim status. AZCOMP includes training with every migration, plus a recorded training library and live webinars.
No, if you take action well in advance of the deadline, the migration is designed to protect your cash flow. Your existing Optum, Change, or RelayHealth connection keeps submitting claims and receiving payments until your eMEDIX enrollment is approved for each payer. Only when eMEDIX is fully ready for a given payer does that payer’s routing switch over, so there is no gap.
Your claims will still submit. For any payer whose eMEDIX enrollment is not yet approved, claims keep routing through your existing connection during the transition window. Eligibility cuts over to eMEDIX immediately, because it uses different routing, but claims and remittance will not experience a gap. The model assumes enrollments take weeks for some payers and handles that gracefully. Start now anyway, because the longer you wait, the more enrollment work compresses into a tight window.
AZCOMP has been named CGM’s #1 reseller in the United States for 21 consecutive years, a distinction awarded by CGM based on sales, customer retention, and partnership strength. We currently support 555 active eMEDIX client businesses, hold a 4.9-star Google rating with more than 620 five-star reviews, and have served thousands of independent practices nationwide since 2000. By every objective measure, we are the most experienced Medisoft and Lytec partner in the country.
Yes. During the Change Healthcare cybersecurity outage in early 2024, AZCOMP migrated 220 practices and billing companies to eMEDIX in about four months, under genuine emergency conditions with very little lead time. The September 1, 2026 cutover has been announced months in advance, which gives everyone more room to plan. If we could move 220 practices in four months under emergency conditions, we can handle this.
Your claims will stop submitting through Optum, Change, or RelayHealth, and your practice will start accumulating unbilled days. The financial impact compounds quickly, since every day without claims going out is a day of future cash flow lost. AZCOMP will still help practices that come to us after September 1, but timing matters, because every additional week of delay is another week of disruption. The right move is to start now, while you still have lead time.
Technically yes, and AZCOMP can still support your Medisoft or Lytec software if you do. But it is not the path we recommend, for two reasons. First, CGM has certified eMEDIX as the clearinghouse purpose-built for Medisoft and Lytec, and other clearinghouses do not integrate as deeply, so you would miss the time-saving tools that only a native, fully integrated workflow provides. Second, your support stops being seamless. When a claim or remittance problem comes up, our support team has no way to see into another company’s clearinghouse to determine whether the issue lives there, which means you become the one who has to go back to your clearinghouse to get it sorted out. With eMEDIX from AZCOMP, one team supports both your software and your clearinghouse, so a single call resolves the whole thing.
If the Optum cutover has you reconsidering whether to keep billing in-house, this is a natural time to evaluate outsourced billing. AZCOMP offers full-service revenue cycle management through a team recognized as Best in KLAS for three years running (2024, 2025, 2026). For practices that want to step away from billing entirely, we handle the whole process end to end. For practices that want to keep billing in-house with more support, we also offer biller staffing and consulting.
The practices that come through this cleanly are simply the ones that start early. A short consult is the easiest first step. We will confirm which software and version you are on, tell you exactly what your path to eMEDIX looks like, and answer any questions, with no obligation and no pressure.
