⚡ Quick Takeaways (30-Second Read)
- The Threat: Hospitals sometimes miscode 100% covered “Well-Visits” as “Sick Visits” if you discuss a separate health issue, triggering deductibles that can average $250 – $600.
- The Law: Under the Affordable Care Act (ACA), preventive care must be free ($0 copay/coinsurance) if coded correctly.
- The Fix: You must demand a code review if you see CPT Code 99213 instead of 99391-99395 on your Explanation of Benefits (EOB) for a routine physical.
The Official Scoop: Why You Might Get a Surprise Bill
The Centers for Medicare & Medicaid Services (CMS) enforces the mandate that preventive services must be covered without cost-sharing. However, a common issue can lead to unexpected bills.
When a patient asks detailed questions or discusses a significant, separate health problem during a routine checkup, coders are sometimes instructed to “unbundle” the visit. This can turn a free checkup into a billable consultation.
The Reality Check: Why This Matters
I saw this play out yesterday when a neighbor, “Sarah,” ran over to my porch in a panic. She was holding a bill from her pediatrician for $485.00.
Sarah had taken her 6-year-old in for his standard annual physical. It should have been free. But during the visit, she spent 10 minutes asking the doctor about her son’s persistent allergies, a topic that required separate evaluation. Because she asked those questions, the billing auditor flagged the visit. They claimed the appointment was no longer just “Preventive” (maintenance) but also “Diagnostic” (problem-oriented).
She was billed for a “Level 4 Office Visit” just for addressing a separate issue. Here is how we fixed it—and how you can too.
The “Split-Bill” Trap: Preventive vs. Diagnostic
Hospitals use a tactic called “Modifier 25.” This allows them to bill you for a sick visit during a well visit. To stop this, you must understand the codes they are hiding on your bill.
| Feature | ✅ Preventive (The Goal) | ❌ Diagnostic (The Trap) |
|---|---|---|
| Cost to You | $0 (100% Covered) | Deductible + Copay |
| Typical CPT Codes | 99381-99387 (New) 99391-99397 (Established) |
99203-99204 (New) 99213-99214 (Established) |
| Diagnosis Codes (ICD-10) | Z00.129 (Routine Exam) | Specific Symptom (e.g., R53.83 Fatigue) |
The Paperwork Guide: How to Slash the Bill
If you receive a bill for a preventive exam, do not pay it immediately. Follow these exact steps to force a recode.
Step 1: Obtain the Itemized Statement
Call the hospital billing department. Do not ask for the “Bill”—ask for the “Itemized Statement with CPT Codes.”
Step 2: Identify the Error
Look for Code 99213 or 99214 appearing on the same day as your physical. If you see this, they have likely double-billed you.
Step 3: The Dispute Script
Call your insurance company (Member Services) first, then the provider. Use this exact wording:
“I am disputing this claim. The primary purpose of my visit on [Date] was Preventive Care under the Affordable Care Act guidelines. The provider has inappropriately unbundled the service using Modifier 25 for counseling that is inherent to a preventive exam. I am requesting a coding review to remove the problem-oriented E/M code.”
Deadline Warning
You typically have 180 days from the date of the Explanation of Benefits (EOB) to file an internal appeal with your insurance. Do not wait.

🙋♂️ Frequently Asked Questions (FAQ)
Can a doctor bill me for asking a question during a physical?
Technically, yes, if the question requires “significant, separately identifiable medical decision making” distinct from the physical. However, you should contest this if the conversation was general counseling that did not lead to a new diagnosis or prescription.
What if the hospital refuses to change the code?
Request a “Peer-to-Peer Review.” This forces the doctor to explain to the insurance company’s doctor why the visit was coded that way. Often, the hospital will drop the charge to avoid the administrative hassle.
Does this apply to all insurance plans?
This applies to all ACA-compliant plans (Marketplace, most Employer plans). It does not apply to “Short-Term” health plans or “Health Sharing Ministries,” which are not bound by federal preventive care mandates.
So don’t be like my panic-stricken neighbor Sarah—who almost wrote a check for $485 out of fear. Check your codes, make the call, and keep your money.
