5 Reasons Ohio Medicaid Agencies Get Audited

Ohio is not being quiet about Medicaid audits right now. Between the Governor’s office, the Auditor of State, and a state Medicaid department that is actively building new fraud detection tools, home care and home health agencies in Ohio are operating under more scrutiny than they have in years.

The good news: almost every recoupment that shows up in an Ohio audit report traces back to one of a handful of repeat issues. And they apply whether you run skilled services, non-skilled services, or both. Here are the five that matter most, and what helps agencies stay ahead of them.

1. Missing or Insufficient Service Documentation

This is the single most common finding in Ohio compliance audits. In one recent examination, five services had no supporting documentation at all. In another, 253 services had zero documentation, and units billed for 67 more services didn’t match what was actually documented. In a separate case, two services had units billed that exceeded the documented time of the visit.

The standard auditors apply is simple: documentation needs to exist, and it needs to match the claim. That’s true whether the service is skilled or non-skilled. A note that’s incomplete or doesn’t line up with what was billed puts that payment at risk, even when great care was delivered.

The best defense is documentation that happens the same day as the visit, checked against the plan before the claim ever goes out. GEOH’s billing team builds that check into the process automatically, reviewing documentation against every claim before submission, so mismatches get caught and corrected before you get a denial.

2. Billing Before the Service Plan Is Properly Signed and Dated

One statistical sample of home health services found 220 billed before the physician had signed the plan of care, 35 with an undated signature, 25 with no plan of care covering the service at all, and 13 where the plan didn’t authorize the specific service billed.

For skilled services, this is the physician-signed plan of care. For non-skilled and waiver services, it’s the signed service or support plan and prior authorization. Different paperwork, same principle: the authorizing document needs to be signed, dated, and on file before the visit happens for the claim to hold up.

Because timing on signatures can be hard to track by hand, especially across a busy caseload, GEOH flags what’s missing before a claim is submitted, including a signature or authorization that isn’t on file yet, so agencies can fix it before it turns into a denial instead of after.

3. EVV Data That Doesn’t Match the Billed Claim

Ohio’s own Auditor of State found that 56 percent of Medicaid-reimbursed home care services in 2022 were processed without the electronic visit verification required by federal law. That gap represented roughly $1.1 billion in claims with no matching EVV visit.

That gap is closing, and fast. Ohio has rolled out EVV hard edits: if a claim doesn’t have a matching visit in the state’s aggregator, it denies automatically, with no grace period. This applies to personal care services and home health services alike, so every agency billing either service type carries the same exposure.

Catching this before it becomes a denial means scheduling, EVV, and billing need to work as one connected system rather than three separate ones. GEOH links scheduling and EVV directly into billing, automatically matching visit data to claims before submission, so a mismatch gets flagged and resolved early instead of coming back as a denial weeks later.

4. Caregiver or Clinician Credentials That Have Lapsed

Ohio auditors have flagged this repeatedly. In one audit, none of six sampled aides had valid first aid certification, and when auditors expanded the sample, they found the same result across the board. In a separate audit, an agency owed nearly $141,000 after aides were found working on expired first aid certifications, a mix-up that traced back to unclear internal recertification timelines. In another case, nearly 80 aides at one agency needed updated first aid certification.

The specific credential differs by role. Aides need current first aid certification and required continuing education hours. Nurses and therapists need current licensure. But the stakes are the same either way: every service delivered by someone without a current credential can be deemed ineligible, regardless of whether the service itself was skilled or non-skilled.

Credential tracking is a lot easier to stay on top of with one system watching expiration dates instead of a spreadsheet or filing cabinet. GEOH keeps every caregiver and clinician credential in one place, with automatic alerts well ahead of expiration, so renewals happen on schedule instead of becoming a surprise.

5. Overlapping or Duplicate Billed Service Times

In one audit, a provider was recouped $7.8 million for nearly 150,000 services that were found to have overlapping service times, alongside missing documentation and services delivered without a care plan. It’s a pattern that shows up often: two different clients billed in two different locations for the same time slot, or a caregiver’s schedule showing simultaneous visits.

A caregiver or clinician can only be in one place at a time, no matter the service type, which makes overlapping time entries one of the easiest patterns for a data-driven audit to catch. Ohio has explicitly built new analytic tools to look for exactly this kind of billing outlier.

This is where automated scheduling earns its keep. GEOH’s scheduling system flags overlapping shifts before they get scheduled, so the conflict gets resolved before it ever has the chance to reach a claim.

Why This Matters More in Ohio Right Now

In May 2026, Governor DeWine announced new Medicaid fraud prevention initiatives aimed at home care providers, backed by an executive order directing more frequent revalidation of high-risk providers. The Ohio Department of Medicaid has paused new enrollment for home health, hospice, waiver, and personal care providers through November 2026, and has already suspended payments to a group of newly identified high-risk providers.

ODM has encouraged existing agencies to get ahead of this by reviewing their own claims for issues now, and the same data analytics behind that effort are built to look across skilled and non-skilled billing equally.

The Bottom Line

Every one of these five issues comes down to the same root cause: a gap between what happened in the field and what got documented, authorized, or billed. Closing that gap is what keeps an agency’s revenue and reputation protected, whether the services delivered are skilled, non-skilled, or both.

This is exactly the kind of gap GEOH was built to close. From documentation and authorization checks to EVV matching, credential tracking, and overlap detection, GEOH’s billing and software services are built specifically for Ohio home care and home health agencies navigating exactly this kind of scrutiny.
