eMEDIX vs Optum/Change Healthcare: What’s Actually Changing for Medisoft Users

If you have been using Change Healthcare or Optum with your Medisoft practice for years, the idea of switching clearinghouses probably feels like more disruption than you want right now. That reaction makes sense. Switching anything in a medical practice takes time and energy, and the last thing you need is a forced change that makes your billing harder. This post is an honest eMEDIX vs Change Healthcare comparison written specifically for Medisoft users, covering what is actually different, where eMEDIX is a genuine improvement, and where the historical arguments for staying on Change Healthcare no longer hold up.

An Important Note:Throughout this post you may see both “eMEDIX” and “Medisoft EDI.” They are the same product. 

eMEDIX is the clearinghouse itself, owned by CGM. Medisoft EDI is the name CGM uses when that same clearinghouse is being specifically talked about for Medisoft practices. So, whether you see eMEDIX or Medisoft EDI, we are talking about the same great clearinghouse software built specifically for your Medisoft.

This Is Not Just a Swap. It Is an Upgrade.

The framing most practices bring to this conversation is “I have to replace my clearinghouse.” That framing is understandable but incomplete. A more accurate way to think about it: the clearinghouse you have been using lost its integration advantage with Medisoft several years ago, and the forced cutover on September 1, 2026 is the moment that makes switching to a better option unavoidable rather than optional.

Practices that make this move are not trading one clearinghouse for another equivalent one. They are moving to a clearinghouse that CGM has been actively developing and improving for years. It is the only clearinghouse built specifically for Medisoft, owned by the same company that makes the software. That is a structural difference, and it shows up in your billing workflow every single day.

How Change Healthcare Used to Work With Medisoft

To understand what is actually changing, it helps to start with an honest account of what the old relationship looked like.

Change Healthcare, and RelayHealth before it, was once the best-integrated clearinghouse option available for Medisoft practices. For a long time it was the default choice, and that made sense given what was available. Many practices have been on it for a decade or more, and the billing workflows around it are deeply familiar to their staff.

The Optum integration inside Medisoft was never a bad one. For years it worked well, and in many ways it still does. The gap between Optum and eMEDIX is not that one is native and one is not. Both integrate inside Medisoft. The difference is that CGM stopped developing the Optum integration a few years ago when eMEDIX became the supported clearinghouse. Since then, every new feature, every workflow improvement, and every update that touches the clearinghouse has been built for eMEDIX and not for Optum. So eMEDIX has not just kept pace, it has pulled ahead, while the Optum integration has stayed where it was.

That development gap is what makes this a genuine upgrade rather than just a swap.

How eMEDIX Works With Medisoft (What Is Actually Different)

Here is where the eMEDIX vs Change Healthcare difference becomes concrete. These are not marketing claims. They are structural differences in how each clearinghouse integrates with Medisoft.

Integration Depth

Both eMEDIX and Optum integrate natively inside Medisoft. But the meaningful difference is how much each integration has grown over the last few years. CGM stopped updating the Optum integration when eMEDIX became the supported clearinghouse, so every improvement since then has gone to eMEDIX exclusively. Claims submission, remittance posting, eligibility verification, claim status, and reporting inside Medisoft have all gotten more capable and more seamless on the eMEDIX side. The Optum integration has not kept up, not because it was built differently, but because it stopped being developed.

Single-Vendor Support vs Being Bounced Between Vendors

This is the difference that practice managers feel most acutely but often cannot name until they experience the alternative. When something goes wrong between Medisoft and Change Healthcare, most practices end up in the middle: call the software vendor, get an answer, take that answer back to the clearinghouse vendor, wait for a response, go back and forth until someone owns the problem. With Medisoft EDI from AZCOMP, one team supports both the software and the clearinghouse. One call. One team. One resolution.

Electronic Secondary Claims

Change Healthcare did not support electronic secondary claim submission for Medisoft users. That meant billers had to print secondary claims and mail them by hand, or pull EOBs from payer portals and reprocess them manually. eMEDIX supports electronic submission of secondary claims directly from inside Medisoft. For practices with significant secondary-payer volume, this single feature eliminates dozens of hours of manual work per month and brings secondary payments in months faster.

Clean Claims Rate

eMEDIX posts a 99% clean claims rate, which beats industry averages. Fewer rejected claims means less time on resubmissions and faster average payment per claim.

Medisoft EDI vs Optum on Eligibility

Both Optum and eMEDIX support eligibility verification, but eMEDIX’s eligibility tools have been developed significantly further. With Medisoft EDI, eligibility runs in about thirty seconds, with results displayed directly in the patient appointment screen. Automated batch eligibility can be set to run on a schedule, so every appointment on the calendar is flagged before the day starts. No phone calls to insurance companies. No separate websites to navigate.

The One-Vendor Advantage

The single-vendor support model deserves its own section because it is the difference practices feel every week, not just on migration day.

Jenny Caraway, who manages billing for Speech Therapy Plus in Richmond, Texas, described what it was like before switching from Waystar to Medisoft EDI: “If we were having problems between Medisoft and Waystar, I was the one in the middle. So I had to reach out to AZCOMP and then get their response and then turn around and turn that to Waystar. There’s that constant back and forth of being caught in the middle.”

That dynamic is not specific to Waystar. It is the inevitable result of using any clearinghouse that is not supported by the same vendor as your practice management software. When the clearinghouse and the software are from different companies, the practice becomes the translator between two support teams that each have limited visibility into the other’s system.

With Medisoft EDI from AZCOMP, that dynamic disappears. AZCOMP supports both Medisoft and Medisoft EDI. When something breaks at the intersection, we can see both sides of the problem. You call one number and one team owns the resolution from start to finish.

What About Direct Payer Connections?

One of the historical arguments for staying on Change Healthcare was the claim that it had the most direct payer connections of any clearinghouse, meaning claims reached payers faster and with fewer intermediary steps.

That argument has eroded significantly since the 2024 Change Healthcare cybersecurity outage. The outage exposed the risk of relying on a single clearinghouse with centralized infrastructure, and eMEDIX along with other clearinghouses worked hard to build out their own direct payer connections in the months that followed. The gap between Change Healthcare and eMEDIX on direct connections is much smaller than it was before 2024, and “most direct connections” is no longer a meaningful selling point for the old clearinghouse.

The honest position: direct payer connection counts are not something we can put a precise number on in a public comparison. But the practical experience of practices that have made the switch does not show meaningful differences in payer reach. What they do notice is that fewer claims come back rejected, because eMEDIX’s 99% clean claims rate means the claims are cleaner before they go out.

Real Results From the Switch

The time savings from moving to Medisoft EDI are not hypothetical. Jenny Caraway’s practice at Speech Therapy Plus in Richmond, Texas, runs roughly 700 claims per month. After switching from Waystar to Medisoft EDI in early 2025, her practice saves approximately 64 hours per month on payment posting alone. Secondary-payer payments now arrive about three months faster because those claims go out electronically rather than by mail.

“It’s been great,” she said. “I’m never going back.”

That outcome is not unique to Jenny’s practice. It is the predictable result of moving from Optum to eMEDIX.

Frequently Asked Questions

Are Change Healthcare, Optum, and RelayHealth the same thing?

Yes. They are all the same clearinghouse service operating under different names from different eras. For a detailed breakdown you can read, Change Healthcare, RelayHealth, Optum EDI: Why They Are All the Same Thing.

Is eMEDIX better than Change Healthcare for Medisoft users?

For Medisoft practices specifically, yes. Both eMEDIX and Optum integrate natively inside Medisoft, but CGM stopped developing the Optum integration years ago when eMEDIX became the supported clearinghouse. Since then, every new feature and workflow improvement has gone to eMEDIX exclusively. Add electronic secondary claims support and the single-vendor support model that comes with eMEDIX from AZCOMP, and the result is a meaningfully better product, not just a lateral move.

Does eMEDIX have as many payer connections as Change Healthcare did?

The gap between eMEDIX and Change Healthcare on direct payer connections has narrowed significantly since the 2024 CHC cybersecurity outage, when eMEDIX and other clearinghouses built out their own direct connections substantially. In practice, Medisoft users who have switched to eMEDIX do not report meaningful differences in payer reach. What they do report is a higher clean claims rate, which means more claims are accepted on first submission regardless of which routing path they take.

Can eMEDIX submit secondary claims electronically from Medisoft?

Yes. eMEDIX supports electronic submission of secondary claims directly from inside Medisoft. Change Healthcare did not support this for Medisoft users, which forced billers to print and mail secondary claims by hand. For practices with significant secondary-payer volume, switching to eMEDIX eliminates that manual process entirely and brings secondary payments in months faster.

What happens to my existing Change Healthcare connection when I switch?

Your existing connection stays active during the migration. AZCOMP migrates your practice payer by payer: your Change Healthcare or Optum connection keeps submitting claims and receiving payments for each payer until your Medisoft EDI enrollment for that payer is approved. Only then does that payer’s routing switch over. There is no gap in claims or cash flow.

Can I stay on Change Healthcare or Optum instead of switching to eMEDIX?

After September 1, 2026, no. CGM will not support the existing Optum and Change Healthcare connection from Medisoft going forward, and Optum is making back-end technical changes that will break the connection regardless. Technically you could switch to a different third-party clearinghouse instead of eMEDIX, but CGM has only certified eMEDIX as the supported clearinghouse for Medisoft, and other clearinghouses do not have the same depth of native integration. You would be trading one external clearinghouse for another and missing the integration benefits that come with Medisoft EDI.
