Eligibility Verification and Prior Authorization: What’s the Difference?

In Medical billing there is a lot of things to be handle, even for experienced doctors and practice managers. With insurance rules constantly changing, new online portals for every payer, and the way reimbursements work shifting all the time. Even if you are working in healthcare for years, still you need to stay update with the billing side, because one small mistake can result in delayed payments or denied claims.

In our recent Blog we explain the importance of Eligibility verification and prior authorization, these tasks directly impact the revenue cycle. They may look similar, but there is a great difference in between the two. And misunderstanding them or skipping them may lead to major issues like claim denials, payment delays, or unexpected bills left for patient. 

In this Blog, we’ll explain both terms clearly, highlight their differences, and show you how getting them right can save your practice from stress and revenue loss.

Why These Two Steps Matter in Medical Billing

The front end of your billing process is like setting the foundation of a building. If it’s not strong, everything else suffers. That’s exactly why eligibility verification and prior authorization are two steps on which every practice should focus on.

What Is Eligibility Verification?

Eligibility verification is the process of checking whether a patient’s insurance is active and what services are covered under their plan before the visit happens.

It answers key questions like:

• Is the patient’s policy currently active?
• What are the copays, deductibles, and co-insurance?
• Services are covered by insurance plan or not?
• Is the provider in-network?

It’s like confirming someone’s ticket before letting them into the event. If you skip this step, there’s a chance the insurance will not cover anything and the cost will be bear by provider or patient.

What Is Prior Authorization?

Prior authorization (sometimes called pre-authorization or pre-certification) is when a provider must get approval from the insurance company before delivering a service or procedure.

This is usually required for:

• Expensive procedures
• High-tech imaging (MRI, CT scans)
• Non-urgent surgeries
• Certain medications
• Repeated therapy sessions

In simple terms, it’s like asking to insurance company that: “Can we move forward with this treatment, and will you cover it?”

The Main Differences

How MedSole RCM Helps You Handle Eligibility and Authorization the Right Way

At MedSole RCM, we understand that providers are already struggling alot. Checking every detail about a patient’s insurance isn’t always the top priority especially in busy clinics or practices with limited staff.

That’s where we come in.

We handle eligibility checks before the appointment.

We don’t just verify the status of insurance, whether its active or not, we dive into the details. We check:

• Coverage specifics for the service type
• Any deductible or copay due
• Network status
• Effective dates

This helps avoid surprises and gives your front desk the confidence to communicate clearly with patients.

We request prior authorizations in time so you’re never waiting.

Many procedures require prior approvals that can take days or even weeks to get. We take that burden off your team by:

• Submitting the necessary documents
• Following up with insurance companies
• Notifying you once we get the approval
• Keeping all communication documented

This ensures that treatments will not be delay, and after providing services you don’t get stuck with denied payments.

We keep everything organized

You don’t have to spend hours checking through emails or chasing missing documents just to figure out what got approved and what didn’t. With our billing process, you can track everything clearly, from insurance verifications to authorization responses. Your team always knows what’s going on, which task is pending, and which needs follow-up. There is a clear communication and easy access to the information you need. A federal advisory body has issued recommendations that are completely aligned with the AMA’s comments and represent a major advocacy win to reduce administrative burdens and costs for physician practices. The AMA is challenging insurance companies to eliminate care delays, patient harms and practice hassles. AMA is fighting to fix prior authorization.

Why Ignoring Eligibility or Authorization Costs You Money

It’s not good for practices to skip these steps especially when the clinic is busy or the service seems routine. But here’s what happens when they don’t pay attention to these two major processes:

• Claim Denials

If a patient's insurance was inactive or the service wasn't covered, the claim will most likely be denied. That means extra work and possibly no payment.

• Payment Delays

Even if the claim is valid, still without authorization, it can be hold for weeks. That directly impacts your cash flow and staff morale.

• Patient Frustration

Patients often assume their insurance will cover everything. When it doesn't, they get upset with your office, clinic or practice and may not return.

• Higher Write-Offs

Denied claims take time to appeal. If they're not corrected in time, practices often write them off as lost revenue.

A Simple Example to Make It Clear

Let’s say a patient comes in for an MRI.

• If you verify eligibility, you’ll know that MRIs are covered under their plan but with a $500 deductible and $75 copay.
• If you get prior authorization, you’ll get to know that the insurance requires pre-approval for all MRI scans and you’ll get that approval prior to time.

If any of those steps is missed, there must be a chance that you will not get paid.

How to Make It Work in Your Practice

Whether you’re a solo provider or running a multi-location clinic, here are a few simple ways to improve your eligibility and authorization process:

1. Use a checklist for every new patient

Make insurance verification part of your workflow.

1. Train your staff to ask the right questions

Eligibility isn’t just about checking the active status of insurance but it’s about knowing what’s covered.

1. Start authorization requests as early as possible

Don't wait until the day before the procedure. Some payers take 7–10 days.

1. Outsource to a team that knows the system

At MedSole RCM, we handled a lot of verifications and authorizations for providers like you on time, with accuracy and consistency.

Key Takeaways

• Eligibility verification is the process which checks the active status of patient's insurance and the service they covered, on the other hand prior authorization is getting approval from the insurance company before delivering specific services.
• If you don’t verify the eligibility or don’t get prior approval, there’s a high chance the insurance company will not pay and that means delayed payments or patient dissatisfaction.
• Insurance may want extra documentation or proof that the service is medically necessary even if the patient has coverage.
• Some payers respond quickly, while others may take days. By starting the process on time helps to avoid delays.
• Incomplete eligibility verification or missed authorizations can result in denied claims and resubmissions.

FAQs (Frequently Asked Questions)

1. Is eligibility verification the same as checking the status of insurance?

No. It also involves to understand what the patient’s plan actually covers. Which means, it has to check how much of their deductible has been met, what their copay will be, the service to be delivered is included in their benefits or not, and your practice is in-network for that plan or not.

2. When is prior authorization required?

Prior authorization is required when any service, test or medication is expensive and when insurance companies want to check in detail before paying. These are not routine treatments like advanced imaging (such as MRIs), some specific surgeries, specialty medications, or ongoing therapy sessions. If you don’t get that approval in advance, there’s a chance that insurance panel will not pay for that service.

3. What happens if prior authorization is not obtained?

If prior authorization is not approved before providing the service, there are the chances that insurance company refuse to pay for it even if the procedure is important for the patient’s health. That means the provider could end up doing the work and not getting paid, or there might be burden on patient for the bill.

4. Can prior authorization be denied even if the patient is eligible?

Yes, just because a patient has active insurance and is eligible under their plan doesn’t automatically mean every service will be approved. Some treatments, tests, or medications require extra steps like medical records or explanation by doctor to prove that the service is necessary. If the insurance company can deny it after review, even if the patient is covered. That’s why it's so important to provide the right documentation when requesting for prior authorization.

5. How long does it take to get prior authorization?

It mostly depends on the insurance company. Some insurances have advanced systems and can give a decision within a few hours especially for simple requests. Others may take several days or even more than that. The reason behind it if they require more paperwork, medical records, or additional reviews. The timeline can also vary based on the type of service. That’s why it’s important to start the prior authorization process as early as possible to avoid delays.
