Free Preventive Care That Turned Into a Bill
The law requires most recommended preventive care to be free, no copay, coinsurance, or deductible. So when a bill shows up for a screening or wellness visit, it is often a coding problem or a charge that should not be there. Find your situation, and what to do.
Which preventive care got billed?
Pick one to see whether the bill should exist, and what to do. Nothing is saved.
Preventive care that is supposed to be free
On non-grandfathered ACA plans, these are covered with no cost-sharing when done as recommended screening. A bill usually means it flipped to diagnostic or was coded wrong.
Colorectal cancer screening
Colonoscopy and stool-based tests (Cologuard, FIT) for adults 45 to 75.
Colonoscopy billed?Cervical cancer screening
Pap and HPV testing on the recommended schedule.
Annual wellness and well-woman visits
Your yearly preventive visit and its standard screenings and counseling.
Immunizations
Routine vaccines recommended for your age (flu, COVID-19, shingles, Tdap, and others).
Blood pressure, cholesterol, and diabetes screening
Recommended cardiovascular and metabolic screenings for eligible adults.
Depression, HIV, and certain STI screenings
Recommended behavioral-health and infectious-disease screenings.
Lung cancer screening
Low-dose CT scans for eligible current and former smokers.
Why free preventive care turns into a bill
- It flipped from screening to diagnostic. Something was found, or you had symptoms, so it was billed as diagnostic. For some services the follow-up must still be free, that is where a dispute starts.
- It was miscoded. A routine screening carrying a diagnostic code, or a missing preventive modifier, triggers cost-sharing that should have been waived.
- A separate charge was added. A lab, a facility fee, a 3D imaging line, or an out-of-network provider you never chose.
- A wellness visit became an office visit. You raised a new problem, and a separate problem-oriented visit was billed on top of the free one.
The deciding move in every case is comparing your bill to your Explanation of Benefits and reading the codes. Our denial-code decoder explains what they mean.

Send us the bill and the EOB. CareRoute Bill Defense checks whether a preventive service was miscoded or wrongly cost-shared, whether a state law required your follow-up to be free, and whether any added charge is proper, then disputes what should not have been billed and negotiates the rest.

Frequently asked questions
Is preventive care supposed to be free?
On most plans, yes. The Affordable Care Act requires non-grandfathered health plans to cover recommended preventive services with no cost-sharing: the services graded A or B by the U.S. Preventive Services Task Force, routine immunizations recommended by the ACIP, and the preventive care in the HRSA women’s and children’s guidelines. No copay, coinsurance, or deductible, even before you meet your deductible. Grandfathered and some non-ACA plans are exempt.
Why did I get a bill for a visit that was supposed to be free?
A few common reasons. The visit may have flipped from screening to diagnostic (something was found, or you had symptoms). It may have been miscoded. A separate charge (a lab, a facility fee, or an out-of-network provider) may have been added. Or you raised a new or ongoing health problem during a wellness visit, and the provider billed a separate office visit on top of the free preventive one.
My screening found something and now I owe for the follow-up. Is that correct?
Sometimes, but not always. For some services the follow-up must still be free: a colonoscopy after a positive stool test, and removing a polyp during a screening colonoscopy, are covered with no cost-sharing on ACA plans, and more than 20 states now require diagnostic and supplemental breast imaging to be free. Whether your follow-up should have been free depends on the service, your state, and your plan type.
A wellness visit turned into a bill. Why?
If you brought up a new or ongoing problem during your annual wellness visit, the provider may bill a separate problem-oriented office visit (an evaluation and management, or E/M, code) on top of the free preventive visit. That is sometimes proper and sometimes a coding choice worth questioning, especially if the problem was minor or already being managed.
Can CareRoute help with a preventive-care bill?
Yes. CareRoute Bill Defense reads your bill and Explanation of Benefits, checks whether a preventive service was miscoded or wrongly cost-shared, whether a state law required your follow-up to be free, and whether any added charge is proper, then disputes what should not have been billed and negotiates the rest. It is free to submit, and you only pay if we save you money.
