Rated 3.6 out of 5 from 6 reviews

Indian Health Service in Lame Deer delivers its full STI panel (HIV, syphilis, gonorrhea, chlamydia, and hepatitis C) at no fee to every patient, with same-visit treatment for bacterial infections and HPV, hepatitis A, and hepatitis B vaccines available by appointment.

TB Testing and Treatment, No Billing Attached

Indian Health Service operates on a no-fee structure across every service it provides: not a waived copay, not a sliding scale with a floor, but zero dollars for testing, treatment, vaccines, PrEP, and TB care alike. That single policy covers the entire visit without exception.

PrEP Is Prescribed Here, Not Sourced Elsewhere

Without on-site PrEP access, a patient in Lame Deer faces the gap of sourcing prevention medication through a separate provider. A real barrier when the nearest alternative may be hours away. Indian Health Service closes that gap by prescribing and managing PrEP and PEP directly.

Hepatitis C Antibody Testing Added to the Standard Four

Beyond gonorrhea, chlamydia, syphilis, and HIV, Indian Health Service runs hepatitis C antibody testing as part of its standard panel. Reactive results feed into the clinic's on-site care framework, TB monitoring and STI treatment already run through the same appointment structure, so hepatitis C findings don't land without a next step.

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.

Congenital syphilis is the fastest-rising STI: what to test, and when

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 Big Horn County tests for syphilis.

Local context

About Muddy, MT

Painted Hill sits above a town where most households own their homes outright and families here run large by any measure, nearly five people per household on average. That settled, rooted feel is real, but it doesn't make getting tested easier when US 212 is the only thread connecting Muddy to the outside world and the nearest options listed on this page require a genuine stretch of highway driving. That distance lands differently depending on who's making the trip. With more than half of working-age adults outside the labor force, schedules here aren't always the nine-to-five kind that lets someone plan a midweek appointment without consequence, but they're not always flexible either.

Young adults in their late teens and twenties represent a meaningful slice of the population, and for them, a round trip on US 212 for routine screening is a real logistical ask, not a minor errand. Cost shapes the calculation too. Typical rents in Muddy stay low, which helps, but only one in ten households clears the threshold where out-of-pocket testing fees feel incidental. For the uninsured or underinsured resident, common enough in a county with Big Horn's income profile, the sliding-scale and free options among those listed on this page aren't a convenience; they're what makes the trip worth planning at all.

Confidentiality & consent in Montana

Minor 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.
