Available testing centers
8 testing options are listed for Billings, MT. The nearest, Planned Parenthood of Montana, is about 1.0 miles away. Compare community and public clinics, private labs, and at-home kits below.
Listings tagged Community health center are federally funded health centers and rural clinics that treat everyone regardless of insurance or ability to pay: required to bill on a sliding fee scale and provide confidential care, and in many states minors may consent to their own STI testing. A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

Planned Parenthood of Montana in Billings tests for gonorrhea, chlamydia, syphilis, herpes, and HIV on a sliding-scale fee with insurance and Medicaid accepted. Appointments are required; bacterial infections are treated the same visit, and Spanish and French are spoken on-site.
Planned Parenthood of Montana in Billings prescribes PrEP, including tenofovir-based regimens, and manages the ongoing lab monitoring that daily oral PrEP requires. That continuity of care at a single site means no hand-off between a prescriber and a separate follow-up provider; the same clinic handles initiation and the regular HIV and kidney-function testing built into the protocol.
Many clinics provide STI testing without any framework protecting a minor's privacy from a parent or guardian, Title X status changes that. As a federally designated Title X site, Planned Parenthood of Montana in Billings is legally required to offer confidential family-planning and STI services to minors, not as a discretionary policy but as a condition of federal funding.
Without a provider who speaks your language at the point of care, nuanced sexual-health conversations collapse into simplified exchanges, and gaps in understanding directly affect whether treatment is followed or prevention tools are used correctly. Planned Parenthood of Montana in Billings delivers care in French and Spanish on-site and extends interpretation services to additional languages, keeping that clinical conversation intact.

Billings Clinic in Billings tests for HIV, gonorrhea, chlamydia, syphilis, hepatitis B, and hepatitis C on a fee-based sliding scale with insurance and Medicaid accepted. No appointment is needed, and bacterial infections can be treated the same visit.
Many STI clinics test and treat but stop short of prescribing HIV prevention, PrEP and PEP require a separate provider visit elsewhere. Billings Clinic carries both, meaning ongoing HIV prevention and post-exposure medication are managed in the same place as your testing.
Billings Clinic treats hepatitis C on-site rather than diagnosing and stopping there, which means a confirmed case moves directly toward a treatment plan without the patient coordinating care across separate providers.
Billings Clinic tests for hepatitis B and hepatitis C alongside the core bacterial and viral STIs, so a single visit surfaces infections that a narrower panel would miss entirely, and both hepatitis strains can be treated here as well.

STD stats & rates
How reported STI rates in Yellowstone County, the county that includes Billings, compare with Montana and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~27% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#8 of 56 Montana counties for chlamydia, a higher rate than 86% of the state
| Infection | Yellowstone County | Montana | United States |
|---|---|---|---|
| Chlamydia | 375.2 641 cases ▲ 16% | 322.6 | 492.2 |
| Gonorrhea | 87.2 149 cases ▲ 29% | 67.7 | 179.5 |
| Syphilis (P&S) | 57.9 99 cases ▲ 111% | 27.5 | 15.8 |
| Syphilis (early) | 29.3 50 cases ▲ 136% | 12.4 | 16 |
| Syphilis (late/unknown) | 35.1 60 cases ▲ 29% | 27.2 | 29.5 |

Reading these numbers: reported case rates only count infections that were actually tested for and diagnosed, so they track local screening effort as much as true spread: a higher rate can reflect more testing, a lower one less. Either way, most STIs cause no symptoms, so treat the figures above as context rather than a verdict, and test on the CDC's schedule regardless of how your area looks.
Between 2020 and 2023 in Yellowstone County, chlamydia has fallen from 488.7 to 375.2 per 100,000 (23%), gonorrhea has fallen from 323 to 87.2 per 100,000 (73%), and P&S syphilis has risen from 4.2 to 57.9 per 100,000 (1279%).
The 2020 dip reflects reduced pandemic-era screening, not lower transmission. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis).
Community health context
Sources: CDC PLACES (ZIP), County Health Rankings, CDC/ATSDR SVI, HRSA HPSA, HRSA MUA/P, Neighborhood Atlas ADI. Lower insurance coverage, fewer routine checkups, and a thin primary-care ratio all raise the value of low-cost public clinics and at-home testing in Yellowstone County.
Local HIV snapshot
Yellowstone County HIV care continuum (2023)
Yellowstone County recorded 4.9 new HIV diagnoses per 100,000 (2023), against 3 statewide and 13.7 nationally. Among Yellowstone County residents living with HIV, 82.4% are in care · 76.5% are virally suppressed. Early, routine testing is what moves these numbers: it is the entry point to PrEP, treatment, and viral suppression.
Sources: AIDSVu (Emory/Gilead) · CDC AHEAD · CDC AtlasPlus · CDC NCHHSTP AtlasPlus (county care continuum). The CDC recommends everyone aged 13–64 test for HIV at least once: every lab and clinic listed above offers HIV testing, and free rapid HIV testing is available at a local health department.
Congenital syphilis, passed from parent to baby in pregnancy, is the fastest-rising STI in the country. U.S. cases climbed from 2,163 in 2020 to 3,882 in 2023. It is almost entirely preventable: the CDC recommends a syphilis test at the first prenatal visit, and every clinic and lab listed for Yellowstone County tests for syphilis.

Local resources & officials
Data & references
Local context
Billings skews toward homeowners, but more than a third of residents rent, and that gap matters when you think about who tends to be between chapters: newer arrivals, younger adults still figuring out the city, people living closer to the bone on $899 a month while Grand Avenue rents compete with groceries and car insurance. That cost reality doesn't leave much cushion for appointments that feel optional, which is exactly how routine STI screening can get quietly deprioritized in a city where driving is the only realistic option for most errands. The households here tend to be on the larger side, with nearly half of adults married. A profile that can make people assume testing is someone else's concern.
But people in their late teens and twenties make up a meaningful slice of Billings, and that's the window when infections spread fastest and are most likely to go unnoticed without a deliberate check-in. The fact that two in three residents are working, many on schedules that don't bend easily, means that a clinic with evening or weekend hours isn't a bonus. It's the reason a test actually happens. With the options listed here, the range across neighborhoods from North Elevation to East Central means most people can find something reachable without crossing the whole city on Airport Road just to get screened.
Getting there
At 7.12/20 on the EPA walkability index, day-to-day errands in Billings generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

Source: Medicare Clinical Laboratory Fee Schedule, CMS, 2025 rates (data.cms.gov). Reference rate for the lab assay only: a clinic visit, sample collection, or a bundled multi-test panel may cost more. Medicaid and most insurers cover STD screening at no out-of-pocket cost.
Two things that actually depend on Montana law: who can consent, and whether partners can be treated without their own visit. Everything else about testing privately is the same nationwide (see below).
In Montana, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Montana permits Expedited Partner Therapy (EPT): if you test positive for chlamydia or gonorrhea, your provider can give you medication (or a prescription) to pass to your partner, no separate exam or appointment needed for them.
Keeping a test private works the same in every state. Whether an STD test shows on insurance (the EOB), how to test anonymously, and self-pay options that leave no insurance trail don’t change by location.
