How to Check Your Insurance Coverage Before a Doctor Visit (And Avoid Surprise Bills)
You see a doctor. You get care. Weeks later, a bill arrives — and it’s nothing like what you expected.
“I thought this was covered.”
“Why is this so expensive?”
“Did I need preauthorization?”
This happens to millions of people every year. And it’s almost always preventable.
At Sheer Health, we help you check your coverage before your appointment — so you walk in knowing exactly what to expect.
Why Checking Coverage Before Your Visit Matters
Most people interact with their insurance after something goes wrong — a denied claim, a surprise bill, a confusing EOB. But the highest-leverage moment is actually before you receive care.
Before any appointment, there are several things to keep in mind that influence what you’ll pay:
- In-network status: whether your provider is in-network, and whether every part of your visit (labs, imaging, biopsies) is too.
- How the visit is billed: preventive, diagnostic, and procedural visits are billed differently, even at the same doctor’s office.
- Deductible progress: how much you’ve met this year, and how much is left.
- Copay vs. coinsurance: a flat fee vs. a percentage of the total cost.
- Preauthorization: whether your plan requires approval before a service, even if your doctor already ordered it.
- Plan limits: caps on how often your plan covers specific services—like dental cleanings, acupuncture or physical therapy—or total annual limits on how many visits you're allowed.
This is the framework Sheer Health checks for every visit. The scenarios below show what happens when one of those gets missed.
What Most People Get Wrong
In theory, you can verify all of this yourself. In practice, here’s what that looks like:
Consider your annual physical. You log into your insurance portal. You search for your provider and hope the directory is up to date (it often isn’t).
You plan to ask about a nagging symptom during your physical, potentially shifting the visit from "preventive" to "diagnostic". Determining your cost requires calling your provider’s office for the CPT and diagnosis codes they plan to use—assuming they’re even willing to provide them ahead of time. Next, you call member services, endure a 20-minute hold, and get transferred to a "specialist" who makes you wait all over again.
By the time you confirm it’s being processed as "diagnostic" and you’re on the hook for the full $3,000, you’re still left with a nagging question: is this information even accurate?
Sheer Health exists so you don’t have to choose between spending hours figuring it out yourself and flying blind.

Scenario 1: The New Doctor Visit That Costs More Than You Expect
You’re seeing a new specialist your primary care doctor referred you to. You assume the referral means you’re covered. But here’s what can go wrong:
The specialist is out-of-network. Your plan covers out-of-network care, but at 50% after a separate $3,000 deductible — not the $1,500 in-network deductible you’ve been tracking. What you thought would be a $50 copay visit is now a $350 out-of-pocket expense.
Scenario 2: The MRI That Needed Preauthorization
Your doctor orders an MRI for a shoulder injury. The imaging center schedules you for next week. Nobody mentions preauthorization.
Your plan requires it for diagnostic imaging. Without it, the claim can be denied after the fact — and you’re responsible for the full cost. That’s typically $1,200 to $3,000 depending on your market.
Sheer Health flags preauthorization requirements before your appointment so this doesn’t happen. If preauth is needed, we tell you exactly what to do and when.
Scenario 3: The Ongoing Care That Adds Up
You're starting physical therapy, twice a week for eight weeks. Your plan covers 30 visits per year with a $40 copay per session. Straightforward, right?
Except your therapist also bills an evaluation code on the first visit, which carries a different copay. And after visit 20, your plan switches from a flat copay to 30% coinsurance — a threshold most people don’t know exists.
Over 16 sessions, the difference between what you expected and what you actually owe could be $400 or more. Sheer Health maps this out before session one.

What to Check Before Any Appointment: A Quick Guide
| Term | Definition |
|---|---|
| Network status | Confirm your provider's network status with the doctor's office before your appointment, as participation can change at any time. Sheer Health can also help verify your coverage. |
| How your visit will be billed | A visit to the same doctor can be billed as preventive (usually fully covered) or diagnostic (subject to your deductible). The difference can be hundreds of dollars, and it depends on why you're going — not where. |
| Preauthorization | Some plans require approval before certain services. If you skip this step, your claim could be denied even if the care is medically necessary. This is one of the most common causes of denied claims. Ask Sheer to check if preauthorization is required for your upcoming visit. |
| Deductible progress | Know how much of your deductible you've met this year, if the care you receive is accruing towards one. If you're close to meeting it, timing a procedure strategically could save you real money. Ask Sheer to check where you are in your deductible and how that might impact how much you’ll have to pay out-of-pocket for the visit. |
| Copay vs. coinsurance | These work differently, and your plan may switch between them depending on the service, where you are in your deductible, or how many visits you've had. Read the fine print — or let us read it for you. |
| Plan limits | Some plans cap the number of sessions or visits covered annually for services like physical therapy or acupuncture. Hitting these limits mid-treatment can leave you with the full bill, so ask us to check if you have a cap or if you’re approaching your cap before you schedule. |
What is Preauthorization, and Do You Need It?
Preauthorization (also called prior authorization) is your insurer's approval to cover a specific service before you receive it. Many plans require it for things like MRIs, CT scans, certain procedures, and specialty medications.
If your provider skips this step, or your insurer decides the request doesn't meet its criteria, your claim can be denied — even if your doctor determined the care was necessary. The best way to find out if your upcoming service needs preauthorization is to check with your insurer directly, or have Sheer Health confirm it for you as part of your coverage review.
