ZoeCare in Bozeman tests for gonorrhea, chlamydia, syphilis, herpes, and HIV, with same-visit treatment for bacterial infections when needed, and every service, from the initial test through any follow-up care, is provided at no fee, with appointments scheduled in advance.
ZoeCare's no-fee structure covers the full scope of what the clinic does (testing, treatment, family planning, and prevention education) without carving out exceptions for specific services or visit types. The consequence is that cost never determines which part of care someone receives.
ZoeCare staffs Spanish-language care directly, meaning clinical conversations (exposure history, treatment instructions, follow-up planning) are conducted by providers working in Spanish rather than routed through external language support. That's an operational difference in who holds the medical conversation.
ZoeCare's panel includes herpes simplex alongside gonorrhea, chlamydia, syphilis, and HIV. A fifth infection that many clinics don't test for as part of a routine screen. For someone who wants herpes status confirmed, that test is available here without sourcing it separately.

Gallatin City-County Health Department operates Bozeman's public health infrastructure, which means STI care (HIV, syphilis, gonorrhea, chlamydia, and TB testing alongside HPV, hepatitis A, hepatitis B, and Mpox vaccines) runs through appointment-based public health channels, with all services provided at no fee.
The fee structure at Gallatin City-County Health Department is singular: every service, from the standard STI panel to the Mpox vaccine, is provided at no charge. Medicaid and insurance are accepted, but there is no cost for those without either. The zero-dollar price applies across the board.
Ryan White program funding positions Gallatin City-County Health Department to carry HIV care from initial testing through ongoing treatment, a standing capacity, not a referral chain. For anyone managing an HIV diagnosis without a consistent provider or reliable coverage, that full continuum being housed in one publicly funded program is the practical difference.

Bridgercare in Bozeman tests for HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis B, and hepatitis C on a sliding-scale fee, with PrEP coverage for the uninsured. All visits are by appointment, and bacterial STIs are treated the same day.
Bridgercare is a federally designated Title X family planning clinic, which means its services for minors are legally confidential. Not disclosed to guardians or insurers without consent. For a young person managing sexual health independently, that federal protection is the standing guarantee, not a clinic-by-clinic policy call.
Bridgercare carries a dedicated funding pathway for PrEP for uninsured patients, meaning the medication itself doesn't dead-end at a cost barrier. PEP is also prescribable on-site, so both the ongoing daily regimen and the short-course intervention live within the same practice.
Missing hepatitis C or herpes from a panel means a separate visit, a separate lab, and a gap where an undiagnosed infection continues. Bridgercare's panel covers herpes alongside hepatitis B and hepatitis C, conditions that a four-infection screen leaves entirely unaddressed.

STD stats & rates
How reported STI rates in Gallatin County, the county that includes Big Sky, compare with Montana and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~24% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#6 of 56 Montana counties for chlamydia, a higher rate than 89% of the state
| Infection | Gallatin County | Montana | United States |
|---|---|---|---|
| Chlamydia | 409.8 518 cases ▲ 27% | 322.6 | 492.2 |
| Gonorrhea | 44.3 56 cases ▼ 35% | 67.7 | 179.5 |

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 Gallatin County, chlamydia has fallen from 504.4 to 409.8 per 100,000 (19%), gonorrhea has risen from 37.8 to 44.3 per 100,000 (17%), and P&S syphilis has risen from 1.7 to 3.2 per 100,000 (88%).

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 Gallatin County.
Local HIV snapshot
Gallatin County HIV care continuum (2023)
Among Gallatin County residents living with HIV, 87.8% are in care · 85.1% 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 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 Gallatin County tests for syphilis.

Data & references
Local context
Big Sky draws people who want to work in hospitality, recreation, and the trades. Jobs that come with long seasons and tight crews. For young adults settling into these roles, the rhythm of the community means building relationships fast, and that same closeness can make a health question feel more complicated to navigate alone. Confidential STI testing is available in and around Big Sky through the clinics and providers listed on this page, and the ability to get screened without word traveling through a tight workplace matters. The town's comfortable, working character means most people are occupied with their jobs and their social lives, not monitoring each other's health decisions.
That said, knowing where to go for a straightforward, private test (whether you're establishing a baseline, following up on a concern, or staying on top of routine screening) removes one source of friction from an already full schedule. Testing services here respect that boundary between your personal health and your public life in Big Sky. Young adults in their twenties and thirties, the group for whom regular screening is most valuable, often find that getting tested when they're thinking about it, rather than waiting for symptoms or a prompting event, keeps their health uncomplicated. The testing sites and clinics available in and around Big Sky support that approach: straightforward access, confidential results, no elaborate explanations required.
Getting there

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.
