How to read these listings

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.

STD stats & rates

STDs & HIV in Montana: the statewide picture

How reported STI rates across Montana compare with the West region and the United States, using the most recent CDC surveillance data. Data for all 56 counties feeds the county and city pages linked below. About 8% of Montana adults are uninsured, a key reason the free and low-cost testing options below matter.

An estimated ~28% of Montana residents are aged 15–34 (ACS): the age group with the highest reported chlamydia and gonorrhea rates nationally, which is why testing access across the state matters.

Montana HIV care continuum (2023)

Montana reports 3 new HIV diagnoses per 100,000, below the U.S. rate of 13.7. The rate has risen100% since 2020. Among Montana residents living with HIV, 90.2% know their status · 93.1% are linked to care · 86.1% are in care · 79.6% are virally suppressed. On prevention, 19.1% of those who could benefit from PrEP are taking it (below the 31.3% national average). Early, routine testing is what moves these numbers: it is the entry point to PrEP, treatment, and viral suppression.

Congenital syphilis in Montana

Pregnant or planning to be?

Congenital syphilis, passed from parent to baby in pregnancy, is the fastest-rising STI in the country. Montana reported 19 cases in 2023, up from 2 in 2020. Nationally, cases climbed from 2,163 (2020) to 3,882 (2023). It is almost entirely preventable with a syphilis test at the first prenatal visit.

Source: CDC NCHHSTP AtlasPlus, 2023.

How Montana's STD rates compare

Montana reported a chlamydia rate of 322.6 per 100,000 in its most recent surveillance year, 34% below the U.S. average of 492.2, and below the West regional rate of 458.2. Gonorrhea ran 67.7 per 100,000, and primary-and-secondary syphilis 27.5.

Among the 50 states and DC, Montana ranks #44 of 51 for chlamydia, a lower rate than 84% of states. Statewide chlamydia has fallen 15% since 2020. The 2020 dip in the trend reflects reduced pandemic-era screening, not lower transmission, and because most STDs are silent, reported counts understate true spread.

Access and cost across Montana

Testing reaches every corner of Montana: 235 public and community health clinics test free or on a sliding scale, private walk-in labs return results in 1–2 days, and at-home kits ship to every ZIP code, with the densest options around Billings, Missoula, and Great Falls.

About 8% of Montana adults are uninsured and 13.3% live below the poverty line, so cost is the most common reason testing gets delayed. Free public-clinic testing, sliding-scale community health centers, and self-pay private labs that never bill insurance keep screening within reach, weigh them on price, privacy, and turnaround using the comparison above.

Who's most at risk, and how often to test

About 28% of Montana residents are aged 15–34. The CDC estimates people aged 15–24 account for roughly half of all new STIs nationwide despite being a small share of the population, so screening guidance is age-aware.

Sexually active women under 25, and anyone with new or multiple partners, should test for chlamydia and gonorrhea every year; everyone aged 13–64 should test for HIV at least once; and pregnant residents are screened early in pregnancy. Because most STDs cause no symptoms, testing on the CDC's schedule, not only when something feels wrong, is the reliable way to catch an infection before it spreads.

Prevention, vaccines, and where to get help

Testing is one pillar; prevention is the other. Montana county and city health departments distribute free condoms, offer HIV counseling, and provide hepatitis A/B and HPV vaccination that heads off several of the infections screened for here, while PrEP and DoxyPEP sharply cut HIV and bacterial-STI risk.

If a result is positive, treatment is close to home: chlamydia, gonorrhea, syphilis, and trichomoniasis are curable with antibiotics, while HIV and herpes are managed with ongoing care. Public health departments treat on site and most private labs include a clinician consult, start with a free or low-cost Montana clinic above, or an at-home kit for private, mail-in screening.

Why it matters

Why STD testing matters

Find a lab near you
  • Reported counts only capture people who got tested, and because most STDs cause no symptoms, real transmission runs higher than any surveillance number suggests, so Montana's below-average numbers are no reason to skip screening, consistent testing is what keeps them low.
  • Untreated, these infections do lasting damage: chlamydia and gonorrhea scar the reproductive system and cause infertility; syphilis can lead to stillbirth and organ damage; any active STI raises HIV risk. Caught early, almost all are curable or controllable with a single course of treatment.
  • Make it routine, not reactive: test as part of your annual check-up if you're sexually active, every three months with new or multiple partners, and before unprotected sex with a new partner. Since 2015 the CDC has urged insurers to cover annual screening for women under 25 at no cost.
  • Testing protects more than you: a silent infection passes to partners unknowingly. When Montana residents test on a schedule, the whole state's transmission drops, knowing your status is the single highest-leverage thing you can do.

Local context

About Montana

Montana posts some of the lowest sexually transmitted infection rates in the country, and that genuinely good news is worth acknowledging. But the harder truth is that low rates don't automatically mean easy access to testing, and in a state where the vast majority of counties lack enough primary-care providers to meet basic health needs, the distance between a reassuring statistic and an actual clinic appointment can be significant. The geography tells the story. With more than a thousand cities and towns spread across an enormous landscape, most Montanans live well outside Billings or Missoula, the two population centers with the most concentrated testing infrastructure. In Great Falls and Bozeman, options exist but serve wide surrounding areas.

Elsewhere, the drive to a clinic can be measured in hours, not minutes, which means testing that's theoretically available isn't always practically accessible. That gap matters most for the roughly one in four Montanans in the young-adult years when STI exposure risk is highest. Montana's relatively low social vulnerability and comparatively modest uninsured rate mean financial and social barriers are less steep here than in many states, but they don't eliminate the distance barrier. Knowing which providers serve your part of the state, and whether telehealth or mail-based testing fits your situation, is the practical starting point.

Confidentiality & consent in MontanaMinor consent and partner treatment (EPT) under state law, plus how to test privately

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).

Can a minor consent on their own?

In Montana, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.

Can my partner be treated too? (EPT)

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.

STD testing FAQs in Montana

Answers to the questions Montana residents ask most before getting tested, from privacy and cost to timing and at-home options.

How does Montana rank for STDs in the U.S.?

Among the 50 states and DC, Montana ranks #44 of 51 for chlamydia, reporting about 323 cases per 100,000 (34% below the U.S. average). Reported counts understate the true total because most infections are silent, which is why routine screening matters statewide.

Which STDs are rising in Montana?

Since 2020, syphilis is up about 555% in Montana. Syphilis, including congenital syphilis passed to newborns, is the fastest-growing STI nationally, so prenatal and routine screening are a priority here too.

What is the HIV situation in Montana today?

Montana reports about 3 new HIV diagnoses per 100,000 residents a year, a rate that has risen in recent years. About 79.6% of residents living with HIV are virally suppressed, undetectable means the virus can't be sexually transmitted (U=U). PrEP and free HIV testing are available across the state.

How common is chlamydia in Montana versus the U.S.?

Montana reported about 323 chlamydia cases per 100,000 (2023), 34% below the U.S. average of 492. It is the most commonly reported STD here, and often silent, so under-25s and anyone with new partners should screen yearly.

Is congenital syphilis a concern in Montana?

Congenital syphilis, when syphilis passes from parent to baby in pregnancy, is the fastest-rising STI crisis in the U.S. (about 3,882 U.S. cases in 2023), and it is almost entirely preventable with a simple blood test early in pregnancy. Montana recommends syphilis screening at the first prenatal visit, so testing while pregnant, or before, matters here.

Will STD testing show up on my insurance in Montana?

If you use health insurance, an Explanation of Benefits (EOB) may be mailed to the policyholder, which could be a parent or spouse. Under HIPAA (45 CFR 164.522) you can ask your insurer in writing to send communications to you confidentially. To leave no insurance trail at all, use a self-pay private lab, an at-home test kit, or a public health clinic, none of these bill your insurance.

Can I get tested anonymously in Montana?

Anonymous HIV testing is available at some sites in Montana; elsewhere testing is confidential (name-based) but still protected. Public health clinics and at-home kits also let you test without involving insurance or your regular doctor.

Can my partner be treated without their own visit in Montana?

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.

Where can I get free or low-cost STD testing across Montana?

Montana's 235 public and community health clinics, county and city health departments, FQHCs, and Title X family-planning sites, test for free or on a sliding scale statewide, which matters where about 8% of adults are uninsured. Pick your city below for the specific clinics nearest you.

How much does STD testing cost in Montana?

Free or sliding-scale at Montana's public clinics and FQHCs (Medicaid accepted); at-home kits run about $50–$150 for a full panel; private walk-in labs charge per test. No one is turned away for inability to pay at public health clinics.

How do I get PrEP for HIV prevention in Montana?

PrEP, a daily pill that prevents HIV, is available across Montana through health departments, FQHCs, and many primary-care and telehealth providers, often free or low-cost via insurance, Medicaid, or manufacturer assistance programs. Alongside testing and treatment, it's central to the state's HIV response. Any Montana clinic can start you, or you can begin through a telehealth service.
