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 Lockwood, 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%).

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.

Data & references
Local context
US Highway 87 East cuts straight through Lockwood, and the clinic options listed here sit close enough that most drives clock in well under fifteen minutes. A real advantage when an afternoon errand can double as a testing stop. That geography matters more than it sounds. Lockwood runs on a working schedule: nearly three in four residents are in the labor force, unemployment is low, and households here tend to be full.
Close to three people on average, with a majority of adults married. Weekday mornings aren't free for most people; neither are long cross-town trips. The fact that options cluster within reach of 87 East means screening doesn't require carving out half a day. For the younger adults in the community (people in their late teens and twenties, a substantial slice of Lockwood's population and the years when STI transmission tends to peak) that kind of proximity is what actually converts an intention into a kept appointment.
The homeownership rate here is notably high, which suggests a stable, rooted community, but the quarter of residents who rent at roughly $895 a month are balancing a real cost load. Clinics offering sliding-scale or no-cost visits, several are listed in the cards above, mean that a tight budget around Count Park or out toward Billings Heights doesn't become the reason a test gets skipped.
Getting there
At 8.81/20 on the EPA walkability index, day-to-day errands in Lockwood generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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.
