Key takeaways
- HealthCare.gov says all Marketplace plans and many other plans must cover a list of preventive services, generally at no cost when you use an in-network provider, even before you meet your deductible.
- That list includes HIV screening for people 15 to 65, hepatitis C screening for adults 18 to 79, syphilis screening for adults at higher risk, and chlamydia and gonorrhea screening for many women.
- $0 isn't guaranteed. Out-of-network labs, tests beyond the preventive list, or a visit for symptoms can all lead to costs, depending on your plan.
- Call your insurer before testing and ask which lab is in network and whether the tests you need count as preventive.
- No insurance, or don't want to use it? Title X clinics provide services regardless of ability to pay, and CDC's GetTested site lists testing locations near you.
Cost stops a lot of people from getting tested, and insurance can feel like a maze. The good news is that many STI screenings fall under the preventive care rules most health plans follow, which can mean no copay at all. The catch is in the details: which tests, for whom, at which lab, and for what reason you're being tested. This guide explains how preventive coverage works for STI testing, based on the preventive services lists on HealthCare.gov, and gives you the questions to ask before you get a bill. It's general information. Plans differ, so your insurer has the final word on your coverage. If you don't have insurance at all, our companion guides to STI testing without insurance and free STD testing are good next reads.
How preventive coverage works
HealthCare.gov explains that all Marketplace health plans and many other plans must cover a set of preventive services. When you get those services from an in-network provider, you generally won't pay a copayment or coinsurance, even if you haven't met your deductible.
Three conditions do most of the work:
The test is on the list
Only specific screenings, for specific groups, are part of the preventive services list.
You fit the group
Many screenings apply to certain ages or to people at higher risk, not to everyone.
The provider is in network
That includes the lab that processes your sample, not only the clinician who orders it.
HealthCare.gov itself cautions that $0 cost isn't guaranteed in every case. Treat the preventive list as a strong starting point, then confirm with your plan.
Which STI screenings are on the preventive list
Here's what the HealthCare.gov preventive services pages list for adults, for women, and during pregnancy, as checked in October 2026.
| Service | Who it's listed for |
|---|---|
| HIV screening | Everyone 15 to 65, and other ages at increased risk |
| Hepatitis C screening | Adults 18 to 79 |
| Syphilis screening | Adults at higher risk, and pregnant women |
| Hepatitis B screening | People at high risk, and pregnant women at the first prenatal visit |
| Chlamydia screening | Younger women and women at higher risk |
| Gonorrhea screening | Women at higher risk, including during pregnancy |
| Cervical cancer screening (Pap test) | Women 21 to 65 |
| STI prevention counseling | Adults at higher risk; sexually active women |
| PrEP for HIV prevention | HIV-negative adults at high risk |
CDC recommends that everyone 13 to 64 get an HIV test at least once, while the coverage list says 15 to 65. The two come from different recommending bodies. If you're outside the coverage range, testing may still be covered, so ask your plan.
Notice what isn't on the list. Routine chlamydia and gonorrhea screening for men isn't listed, and neither are herpes blood tests or trichomoniasis. That doesn't mean your plan won't pay for them. It means they may be subject to your normal deductible and copays. To see how coverage lines up with medical guidance, compare this table with our guide to CDC screening recommendations by group.
Why you might still get a bill
Most surprise bills for STI testing trace back to one of these situations:
- An out-of-network lab. Your clinician may be in network while the lab that runs the tests isn't. Ask which lab will be used.
- Tests beyond the preventive list. A broad panel can include tests that aren't preventive for your group. Those may be billed under your regular cost-sharing.
- Testing for symptoms. Preventive coverage is built around screening people without symptoms. If you go in because of symptoms, the visit and tests may be handled differently under your plan. You should still go, because symptoms deserve care. Just ask about costs.
- An office visit charge. Depending on your plan and the reason for the visit, the appointment itself may carry a charge even if the screening doesn't.
- Not fitting the listed group. For example, a screening listed "for adults at higher risk" depends on how your clinician documents your situation.
Many screenings are listed for people "at higher risk." Sharing an accurate sexual history helps your clinician order the right tests, and can affect whether a screening counts as preventive. It's a routine medical conversation, and a good clinician will keep it that way.
How the list applies in common situations
These examples show how to match your situation to the preventive list. They aren't coverage promises, since your plan decides, but they show which questions to ask.
A 23-year-old woman, no symptoms
Chlamydia screening for younger women, HIV screening and cervical cancer screening all appear on the list. Gonorrhea screening is listed for women at higher risk, so share your history and ask whether it applies.
A 30-year-old man with a new partner
HIV and hepatitis C screening are listed for his age. Syphilis is listed for adults at higher risk. Chlamydia and gonorrhea tests may still be ordered, but may fall under his regular cost-sharing.
Someone starting PrEP
PrEP itself is on the adult list for people at high risk of HIV. Ask how the regular HIV and STI tests that come with PrEP visits are billed under your plan.
A 26-year-old on a parent's plan
The same preventive rules apply, but statements may go to the parent as policyholder. Ask the insurer about confidential communications before testing.
In every case, the step that prevents the most surprises is the same: confirm the lab is in network and ask which of your tests count as preventive. Our guide to the PrEP STI testing schedule explains what those regular visits usually include.
What to ask before you test
- Call the number on your insurance cardSay you'd like preventive STI screening and ask which tests are covered at no cost for someone your age and sex.
- Ask about the lab"Which labs are in network for me?" If your clinician uses a different lab, ask them to send your samples to an in-network one.
- Name the specific testsAsk about each test you plan to get, including any throat or rectal sites, so nothing on the order surprises you.
- Ask about the visit itself"Will the appointment be billed separately from the screening?"
- Write it downNote the date, the representative's name and a reference number in case you need to appeal a bill later.
At-home kits and insurance
Home-collection kits and online lab orders are convenient, but coverage varies. Many services are pay-as-you-go, and some may work with insurance. Before ordering, check:
- Does the service bill insurance, or is it self-pay only?
- If it bills insurance, is its lab in your plan's network?
- Which tests and body sites does the kit include?
- Is there a clinician to talk to if a result is positive, and is that included?
Our guide to FDA-authorized at-home STI tests explains the difference between self-tests, mail-in kits and online lab orders, and questions to ask before ordering online covers the fine print.
Privacy when you use insurance
Using insurance creates paperwork. Statements such as an explanation of benefits may go to the main policyholder, which matters if you're on a parent's or partner's plan. If that's a concern:
- Ask your insurer how it handles confidential communications and whether statements can be sent to you directly.
- Consider a Title X family planning clinic or a health department clinic, which may not require insurance at all.
- Read our guide to how private at-home tests are, and for people under 18, confidential testing for teens.
Options without insurance
Not having insurance, or choosing not to use it, shouldn't keep you from testing.
| Option | What to know |
|---|---|
| Title X family planning clinics | The federal Office of Population Affairs says Title X services include STI services, are confidential, and are provided regardless of ability to pay. |
| CDC GetTested locator | gettested.cdc.gov lists HIV, STD and hepatitis testing locations across the U.S. CDC notes that some locations offer free or low-cost testing. |
| Free HIV self-tests | CDC says you can order free HIV self-tests through Together TakeMeHome, and that GetTested lists organizations offering free or reduced-cost self-tests. |
| Local health departments | Many run sexual health clinics. Services and costs vary by location, so call ahead. |

Frequently asked questions
Is STI testing free with insurance?
Often, for certain screenings. HealthCare.gov says all Marketplace plans and many other plans must cover listed preventive services, such as HIV screening for people 15 to 65 and chlamydia screening for younger women, generally at no cost from an in-network provider. Tests outside that list, out-of-network labs, or visits for symptoms may cost something.
Why did I get a bill for STI testing when it's supposed to be preventive?
Common reasons include an out-of-network lab, tests that aren't on the preventive list for your group, a separate charge for the office visit, or testing done because of symptoms. Call your insurer, ask why the claim was processed that way, and request a review if you think it should have been covered as preventive.
Does insurance cover STI testing for men?
HIV, hepatitis C and, for people at higher risk, syphilis and hepatitis B screenings are on the adult preventive list. Routine chlamydia and gonorrhea screening for men isn't listed, so it may fall under your regular deductible and copays. Check with your plan.
Will my parents or partner see my STI test on the insurance statement?
They might, if they're the main policyholder, because statements like an explanation of benefits can go to them. Ask your insurer about confidential communications, or consider a Title X clinic or health department clinic, which may not require insurance.
Where can I get tested if I don't have insurance?
Title X family planning clinics provide services regardless of ability to pay, and CDC's GetTested site at gettested.cdc.gov lists HIV, STD and hepatitis testing locations, some of which are free or low-cost. CDC also points to free HIV self-tests through Together TakeMeHome.
