Federal qualification locks in sliding-scale fees tied to income, making syphilis, gonorrhea, and chlamydia screening reachable without an appointment for virtually anyone who walks in.
Tests offered
Fees & payment
Tennessee Department of Health in Mountain City charges nothing for its services, accepting Medicaid, Medicare, and private insurance while offering a sliding scale for everyone else. The clinic tests for HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis C, and TB, treating bacterial STIs and TB on the same visit by appointment.
The no-fee model here is built on Medicaid, Medicare, and insurance billing, with a sliding scale absorbing what those don't cover. PrEP for the uninsured is funded separately, so the cost floor stays at zero regardless of which program a patient qualifies under.
Interpretation services are available for non-English languages at this clinic, which means a patient's conversation about DoxyPEP dosing, PrEP adherence, or hepatitis C treatment isn't compressed by language barriers. The clinical detail comes through intact.
Without on-site PrEP, PEP, and DoxyPEP in Mountain City, the nearest alternative likely means a longer drive and a separate provider relationship. Gaps where prevention lapses. Tennessee Department of Health prescribes and manages all three, keeping the entire prevention regimen consolidated at one appointment.

STD stats & rates

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 Johnson County, chlamydia has fallen from 245.2 to 125.2 per 100,000 (49%), gonorrhea has fallen from 150.4 to 21.8 per 100,000 (86%), and P&S syphilis has fallen from 5.6 to 5.4 per 100,000 (4%).

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 Johnson County.
Local HIV snapshot
Johnson County HIV care continuum (2023)
Johnson County recorded 0 new HIV diagnoses per 100,000 (2023), against 14.8 statewide and 13.7 nationally. Among Johnson County residents living with HIV, 91.4% are in care · 74.3% 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 Johnson County tests for syphilis.

Data & references
Local context
South Shady Street on a weekday morning moves slowly, a mix of through-traffic heading toward US 421 and locals whose options for almost anything requiring a drive are genuinely limited by distance. Mountain City sits in a corner of Tennessee where nearly everything involves getting in a car, and for the younger adults who live here, people in their late teens and twenties building relationships and households in a place where typical rent runs well under five hundred dollars, that distance compounds what is already a practical barrier to routine health care. The labor-force picture here is worth noting: a smaller share of residents are actively employed compared to most Tennessee communities, which shapes how households budget and schedule. With well under one in ten households earning above six figures, out-of-pocket testing costs land differently than they would in a higher-wage market.
At the same time, the homeownership rate suggests a stable, rooted population: people who aren't just passing through, and who have real reason to stay invested in local health infrastructure. Because Mountain City itself has no listed testing options at this time, every option on this page means committing to a real trip. Knowing hours, fees, and distance before you go, all of it visible in the clinic cards above, is the practical first step toward making that trip count.
Getting there
At 5.52/20 on the EPA walkability index, day-to-day errands in Mountain City 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 Tennessee 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 Tennessee, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Tennessee 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.
