Insurance companies are permitted to establish a network and require you to purchase from within that network. If you purchase outside of the network, they only have to reimburse $12 per kit.

If you purchase an over-the-counter COVID-19 test from a pharmacy, store, or online retailer and are charged for your test, keep your receipt and submit a claim to your insurance company for reimbursement. If your plan has not set up a network of preferred stores, pharmacies, and online retailers at which you can obtain a test with no out-of-pocket expense, you will be reimbursed the amount of the cost of the test. For example, if you buy a two-pack of tests for $34, the plan or insurer would reimburse $34.

If your plan has set up a network of preferred stores, pharmacies, and online retailers at which you can obtain a test with no out-of-pocket expense, you can still obtain tests from other retailers if you buy them outside of that network. Your plan is required to reimburse you at a rate of up to $12 per individual test (or the cost of the test, if less than $12). Save your receipt(s) to submit to your plan for reimbursement at a rate of at least $12 per individual test (or the cost of the test, if less than $12).

You can order free tests here: covidtests.gov (but don't expect to receive them super-fast as they set up the system, and they're going to be overwhelmed initially).

What if I'm on Medicare?
Medicare covers at no charge Covid-19 testing done in a lab when ordered by a medical professional. [This means home tests are not covered by Medicare.]
Those enrolled in Medicare Advantage plans should check with their insurers to see if the costs of the home tests will be covered.

https://www.cms.gov/how-to-get-yo...t-for-free
For people covered by original fee-for-service Medicare, Medicare pays for COVID-19 diagnostic tests performed by a laboratory, such as PCR and antigen tests, with no beneficiary cost sharing when the test is ordered by a physician, non-physician practitioner, pharmacist, or other authorized health care professional. People with Medicare can access one lab performed test without cost sharing per patient per year without an order. At this time original Medicare cannot pay for at-home tests through this program. Medicare Advantage plans may offer coverage and payment for at-home over-the-counter COVID-19 tests, so consumers covered by Medicare Advantage should check with their plan.

What if I'm on Medicaid?
Medicaid and the Children's Health Insurance Program, known as CHIP, already cover home tests with no cost-sharing.
But enrollees should contact their state agencies for specific coverage details.

The tests won't be subject to copays or deductibles.

There are a lot of "home tests" which require you to mail the sample in to the lab. This means it's going to days at least a couple of days, or longer, to get your results. If that timeline doesn't work for you, pay attention to what test you order.
If you're flying internationally, a home test likely won't meet any requirement for covid testing.
