Does Medi-Cal Cover a TB Test? Costs, Coverage, and Access

Yes, Medi-Cal covers TB tests at no cost to the member. Tuberculosis screening is treated as a preventive service, which under Medi-Cal means no copay, no coinsurance, and no other out-of-pocket charge when a provider orders the test based on your risk factors.

Which TB Tests Are Covered

Medi-Cal covers the standard screening methods a provider is likely to use. Those are the tuberculin skin test (the Mantoux or PPD test), the QuantiFERON-TB Gold Plus blood test, and the T-SPOT.TB blood test.¹² Your provider decides which one to use based on your risk factors and clinical situation.

If a screening test comes back positive, the follow-up workup is also covered. That includes chest X-rays to check for active disease, laboratory services, and physician evaluation visits.³⁴

What You’ll Pay

Nothing. TB screening carries no cost-sharing under Medi-Cal because it falls under the U.S. Preventive Services Task Force’s grade B recommendation for screening adults at increased risk for latent TB infection, and Medi-Cal covers all USPSTF grade A and B preventive services without charge to members.¹⁵

Prior authorization is not required for the screening test itself. A primary care physician can order it directly when they identify risk factors.⁶

People who are infected with TB but don’t qualify for full-scope Medi-Cal may still get outpatient TB services at zero share of cost through a separate Medi-Cal Tuberculosis Program (aid code 7H), funded under Title XIX of the Social Security Act.⁷

Who Actually Gets Tested

Medi-Cal doesn’t test every member at every visit. Screening is targeted at people with identified risk factors. High-risk groups include people living with HIV, close contacts of someone with active TB, individuals born in countries with high TB rates, people who use injection drugs, residents and employees of congregate settings like long-term care facilities, and those with medical conditions that weaken the immune system.⁶

New Medi-Cal managed care members are required to get an initial health appointment within 120 days of enrollment, and TB testing is required at that visit if the member falls into a high-risk category.⁶ For children and adolescents up to age 20, screening follows the American Academy of Pediatrics Bright Futures guidelines, which include a TB risk assessment at routine well-child visits.⁵

Assembly Bill 2132, signed by Governor Gavin Newsom in September 2024 and effective January 1, 2025, requires adult primary care providers to offer a TB test when they identify risk factors, as long as the patient’s insurance covers it. Medi-Cal does, so providers treating Medi-Cal members are expected to comply.⁸⁹ If you have risk factors and haven’t been asked about TB, it’s reasonable to bring it up with your provider.

What Happens After a Positive Result

Coverage continues past the initial test. For latent TB infection, Medi-Cal covers the full course of treatment medications. Preferred regimens on the Medi-Cal Rx Contract Drugs List include three months of weekly isoniazid plus rifapentine, four months of daily rifampin, and three months of daily isoniazid plus rifampin. Longer alternative regimens of six or nine months of daily isoniazid are also covered.¹⁰

For active TB disease, covered services include physician visits, outpatient hospital care, laboratory and radiology services, prescription medications, case management, and Directly Observed Therapy (DOT).⁴ Two administrative notes worth knowing: TB medications are dispensed through Medi-Cal Rx rather than through a managed care plan’s pharmacy benefit, and DOT services are paid directly by local health departments rather than through your health plan, though you stay enrolled with your plan for everything else. A DOT referral does require authorization, and any suspected or confirmed active TB case must be reported to the local health department within one working day.⁶

How to Get a TB Test on Medi-Cal

Start with your primary care provider. Most Medi-Cal members are in a managed care plan and generally need to use in-network providers. L.A. Care’s member handbook, for example, states that members must get most covered services from in-network providers, with exceptions for emergencies, family planning, and out-of-area urgent care.¹¹ You can usually find participating providers in your plan’s online directory or by calling member services.

County public health departments are another route. Many offer TB testing at no cost regardless of insurance, which can help if you want a walk-in option:

In San Francisco, the San Francisco Free Clinic (4900 California Street) and the AITC Immunization and Travel Clinic (27 Van Ness Ave) both test by appointment, and several San Francisco Health Network clinics test enrolled patients.¹²
In Orange County, the Health Care Agency clinic at 1725 West 17th Street in Santa Ana provides screening and treatment Monday through Friday, with no skin testing on Thursdays.¹³
In San Diego County, regional public health centers test high-risk individuals who can’t access services elsewhere; insured residents are expected to use their own providers first.¹⁴

Other counties run similar programs. Calling your local health department’s TB control office is the fastest way to find what’s available near you.
