BlueCross BlueShield of Alabama is waiving cost-sharing requirements for coronavirus treatments, following a slew of other insurers nationwide.

BCBS had already waived copays and deductibles for telehealth appointments and COVID-19 testing, but have now joined the United States’ top three insurers in eliminating the step costs associated with treating the virus.

Research by the Kaiser Family Foundation shows inpatient treatment for COVID-19 could top $20,000. But for patients who require ventilator support, the cost would be much higher, with 96 hours of ventilation closing in on $90,000.

“For fully-insured employer customers, we are waiving all member cost sharing for services or supplies rendered with a COVID-19 related diagnosis, as outlined by the CDC and American Medical Association, and the related in-person or telehealth office visit, urgent care visit, emergency room visit, or behavioral health visit,” said Koko Mackin, vice president of corporate communications at BCBS of Alabama. “Out-of-network treatments will be covered at the out-of-network benefit level. Self-funded employer customers have the option to also implement this COVID-19 related benefit.”

Congress recently passed the Families First Coronavirus Response Act that requires require private health plans to cover testing for the coronavirus with no cost-sharing, but according to Kaiser Family Foundation, fewer changes have been adapted for coronavirus treatments.

Cigna, Humana and Aetna all announced last week they would waive consumer costs associated with treating COVID-19.
