You can lose Medicaid revenue long before a claim ever reaches billing.
Often, it starts with the authorization.
An authorization tells an agency what a client is approved to receive, including the service, amount, frequency, and dates covered. The exact rules vary by state, Medicaid program, and payer. But operationally, the job is the same: keep what's approved, what's scheduled, what actually happened, and what gets billed aligned.
When those four things drift apart, revenue can slowly start slipping through the cracks.
Here are seven places to look:
Medicaid authorization is the approval that says which services an eligible person can receive under a Medicaid program.
Depending on the state and payer, it may specify the service, amount, frequency, duration, and dates covered. In managed care, the managed care organization (MCO) may be responsible for managing or issuing the authorization.
Also, it matters to revenue because authorization is part of the chain that determines whether a service can be billed.
CMS’s HCBS billing-validation guidance identifies three essential tests: whether the individual was eligible for the waiver on the date of service; whether the billed service was included in the approved service plan and met the authorized type, scope, amount, duration, and frequency, including applicable prior authorization requirements; and whether the service was actually provided and supported by appropriate documentation.
Also, whether the service was actually provided and supported by appropriate documentation. Following applicable prior authorization requirements is part of the second test.
That doesn't mean every state or payer uses the exact same process. It does mean authorization isn't something an agency can safely treat as paperwork sitting off to the side.
It has to stay connected to the work being scheduled and delivered.
An end date sitting in a file doesn't do anything by itself.
The client still needs care. The caregiver still shows up. The schedule still looks normal.
Nothing about the day-to-day operation necessarily tells the scheduler that the authorization has expired.
You may find out when someone checks the record. Or you may find out later when a claim doesn't go through.
Texas offers one example of a more structured approach. In STAR+PLUS HCBS, Texas uses a monthly Individual Service Plan Expiring Report that identifies plans expiring within the next 90 days.
MCOs must provide a status update for members whose plans expire within 45 days.
That's a state-level process. It is not a universal agency deadline. But the operational idea is useful because expiration tracking works better when it happens on a defined schedule rather
than when someone remembers to check it.
Your agency should be able to answer the following:
The exact lead time you need depends on your program and payer. The important part is that an expiration date should trigger a workflow, not just sit in a record.
“Patients are scheduled too far in advance, and authorizations expire and are not renewed expeditiously.” Authorization gaps can start with something as simple as scheduling ahead of an authorization’s approved period. Keeping upcoming schedules, authorization end dates, and renewal activity connected can help agencies catch these gaps before they affect delivered services or billing.
— Kelli Hansen, Home Care Industry Expert
Expiration is what you see.
Late renewal is often what caused it.
If an authorization isn't reviewed until it's close to its end date, there may be little time left to gather documentation, answer payer questions, correct a submission, or deal with a change in the client's needs.
There's no single national renewal timeline that works for every Medicaid program. That's why the agency's internal process matters.
Break renewal into stages instead of treating it as one task.
| Stage | What to check |
|---|---|
| Before expiration | Current services and units, changes in client needs, required documentation, owner |
| While pending | Submission status, payer requests, outstanding information, time remaining |
| After approval | New dates and units, schedule, billing, planned service utilization |
The point is to keep the authorization connected to day-to-day operations throughout the process, not just when someone receives the approval.
This is one of the clearest ways a scheduling decision can become a revenue problem.
A scheduler knows a client needs ongoing care, so they build the calendar weeks or months ahead.
The authorization, meanwhile, may cover a shorter period or fewer units.
Now the schedule says one thing and the authorization says another.
Kelli's broader point is that agencies can lose revenue when visits continue after an authorization expires or when authorization requests are made too late. Her experience also highlights the importance of having a defined process and a designated person responsible for managing authorizations.
Colorado's Medicaid program provides another example. In November 2025, the state issued guidance stating that providers must have an approved Prior Authorization Request (PAR) on file. And that billed services must correspond to the approved service, dates, and units.
The state also warned that claims without a valid PAR or claims exceeding approved units would be denied once the applicable system edits were reinstated.
The practical lesson is simple:
1. Is there an active authorization covering the provided service and date?
2. How much of the authorization has already been scheduled or used?
That becomes especially important when an agency has recurring schedules, multiple programs, or authorization units that change during a client's care period.
An authorization isn't necessarily fixed once it's issued.
A payer may approve different units, change dates, add a service, or issue a new authorization after a reassessment.
The problem usually starts when the update reaches one person but not everyone who needs it.
A revised authorization sitting in an inbox doesn't help a scheduler working from the old one.
That's how a small administrative change can turn into a chain of operational problems:
When an authorization changes but the schedule is not updated, the visit may, or most likely will, still happen based on outdated information. Billing then works from the same outdated details, and the discrepancy may not surface until later in the billing or claims process.
A simple handoff process can break that chain.
Whenever an authorization changes, the answers to the questions given below become necessary:
The goal is one current version of the authorization.
This is where authorization management gets particularly difficult.
A renewal is pending. The client still needs care. The caregiver still shows up.
Whether those services can continue, and whether they can ultimately be reimbursed, depends on the specific Medicaid program, payer, authorization status, and applicable rules.
The key question isn't simply whether the service was eventually billed. It's whether the agency had a clear, documented process for handling services when authorization status was uncertain.
That's why an authorization gap shouldn't be handled as an improvised exception.
Your agency should already understand and know:
The goal isn't to create one universal policy for every Medicaid program.
It's to make sure your team doesn't have to invent a process after the gap has already happened.
An authorization can be active and still create a revenue problem. Why?
Because approved hours aren't necessarily the same as scheduled or delivered hours.
A caregiver works longer than expected. A visit gets moved. A shift is covered by someone else. A client cancels. A schedule changes.
None of those events necessarily creates a problem on its own.
But over the course of an authorization period, small changes can add up.
Four factors bring the picture closer to transparency:
Authorized: What the payer approved.
Scheduled: What the agency plans to deliver.
Delivered: What actually happened.
Billed: What the agency submitted.
Put those together, and you can start seeing where the process is breaking.
When authorized hours exceed scheduled hours, the agency may have unused capacity. When scheduled hours exceed authorized hours, it may indicate a potential scheduling risk that needs to be reviewed before services are delivered.
Delivering more hours than authorized can create an overutilization issue, depending on the program’s rules. And when delivered hours are higher than billed hours, it’s worth checking whether some hours were missed during billing or not.
The goal isn't to squeeze every approved hour out of an authorization.
It's to know whether the four numbers still agree.
Revenue protection is one part of a bigger operational picture. Scheduling, staffing, billing, and financial discipline all affect how much of the work your agency can turn into predictable and consistent revenue.
Billing may be where an authorization problem becomes visible, but it isn't necessarily where the problem began.
By the time a claim reaches billing, the agency may already have paid for the caregiver's time, completed the documentation, and closed out the visit. If the authorization was expired, changed, or exceeded earlier in the process, billing may be left trying to reconcile a problem that started upstream.
That is why recurring authorization-related issues need more than just a billing fix.
Start by looking at what happened before the claim:
Billing can identify the discrepancy. The goal of authorization management is to catch it earlier before it becomes a claim problem.
Sadiatun's broader point of view is that agencies can provide services without confirming authorization, eligibility, approved hours, payer requirements, or whether EVV and documentation are complete. She also recommends regular reconciliation across scheduled and completed visits, billed claims, payments, denials, and outstanding balances

They should monitor the exact metrics. But depending on their state, programs, payers, and internal workflow.
An authorization management view can help your team answer questions like these:
| What to monitor | What it tells you |
|---|---|
| Authorizations expiring soon | Where renewal risk is building |
| Pending renewals | What is still unresolved |
| Authorized vs scheduled | Whether the schedule is getting ahead |
| Authorized vs delivered | How approved services are being used |
| Delivered vs billed | Where billing gaps may exist |
| Authorization-related denials | Which problems are recurring |
| Under- or overused authorized hours | Where utilization needs attention |
| Status by office, payer, or program | Where problems are concentrated |
The value increases when these metrics are connected.
An agency that sees an authorization expiring soon and sees how much of that authorization is already scheduled has more information than an agency looking at either number alone.
That's the difference between reporting what happened and spotting where action may be needed.
EVV and authorization management are not the same thing.
But they are connected.
Under Section 12006(a) of the 21st Century Cures Act, states must implement EVV for Medicaid personal care services and qualifying home health services that require an in-home visit. Federal EVV requirements include electronically verifying the type of service, individual receiving the service, individual providing the service, date of service, start and end time, and location of service delivery.
Think of the four records this way:
Authorization: What's approved?
Schedule: What's planned?
EVV: What happened?
Billing: What was submitted?
EVV doesn't replace authorization management. It gives the agency another operational record that needs to line up with the authorization, schedule, and claim.
Texas provides a useful example of how closely these records can be connected. In January 2026, TMHP advised providers and financial management services agencies to review visits in their EVV system or EVV Portal and make sure they had been accepted by the EVV Aggregator before billing claims.
The notice also referenced EVV rejections related to Medicaid member authorization and eligibility issues.
The exact workflow varies by state.
The principle doesn't:
Don't let authorization, scheduling, EVV, and billing become four separate versions of what happened.
Software won't fix a process your agency hasn't defined. What it can do is make that process easier to run consistently.
When comparing home care software, look at whether authorization information stays connected to the work that depends on it:
The important question isn't simply whether a system has an authorization field.
Ask whether your team can use that information where decisions are being made.
That's where reporting becomes important.
CareSmartz360 home care software includes client authorization management alongside scheduling, EVV, billing, and reporting workflows, giving agencies a connected operational view rather than requiring authorization information to live separately from the work it affects.
It also supports importing multiple client authorizations through Excel, which can reduce the need to enter authorizations individually.

Medicaid revenue doesn't always slip away because billing made a mistake. Sometimes the problem started weeks earlier. A renewal wasn't started in time. A schedule ran beyond what was approved. An authorization changed, but the update stayed in someone's inbox. A visit happened during a gap that nobody had resolved. Or billing was the first team to notice that the numbers didn't line up.
Good authorization management spreads those checks across the entire process instead of leaving billing to catch everything at the end.
The simplest way to think about the process is as four connected steps: what’s authorized, what’s scheduled, what’s actually delivered, and what’s ultimately billed.
When your team can see all four and act when they stop lining up, you have a much better chance of finding an authorization problem while it's still an operational problem, rather than after it becomes a revenue problem.
The rules will always depend on the state, program, and payer. The operational question is much simpler: Can your team spot an authorization problem before it becomes a billing problem?
