There are still more questions than answers about the costs of coronavirus testing

As COVID-19 testing is poised to ramp up following the federal government’s recent measures and the rollout of a range of private initiatives, there are still more questions than answers about who will be able to access these tests, who will pay for them or any potential treatment, and how successful these measures will be in deterring the spread of the coronavirus across all parts of American society.

Speaking at the White House press conference on Sunday, Vice President Mike Pence once again stressed that the measures will support all Americans, but offered few details. Last week, he announced that “all the insurance companies” agreed “to waive all copays on coronavirus testing and extend coverage for coronavirus treatment in all of their benefit plans.”

“As we expand testing, we’re so pleased that Congress joined with our administration to make sure that cost is never going to be a barrier to anyone getting a coronavirus test,” Pence said at the briefing. “Now all coronavirus testing is free, and it’s free for every American, including uninsured Americans.”

The full extent of the insurers’ commitment to shoulder the burden of the outbreak, and the level of support from the federal and state level, remains to be seen. 

Blue Cross Blue Shield, Aetna, Cigna, Humana and UnitedHealth Group were among the attendees at the event, according to the White House. So far most insurance companies have committed to waiving co-pays for COVID-19 testing only, not for treatment. Fortune reached out to all insurers named by the White House, and most referred to an online statement or offered comments via e-mail. Cigna did not respond to a request for comment.

For example, Blue Cross Blue Shield’s COVID-19 guidance says coverage “will be consistent with the standard provisions of the member’s health benefits.” 

Some are also covering telemedicine co-pays. “If a commercial member sees a telemedicine provider for their follow-up visit, there are no co-pays as part of our zero co-pay telemedicine offering available for the next 90 days,” according to an e-mailed statement from Aetna.

Even for those with insurance, there are still a lot of details to be worked out.
