UnitedHealthcare (UHC) this week became the latest major insurer to waive members’ cost sharing for COVID-19 treatments. The health insurer said it would waive the associated costs for members in its fully insured commercial, Medicare Advantage, and Medicaid plans.

UHC added that it’s working with interested self-funded employer plans to offer the same waivers.

Anthem announced similar steps, saying it would cover the cost-sharing for COVID-19 treatment through May 31 for its Medicare, Medicaid, individual market and fully insured employer plans. The insurer also said it was “strongly encouraging” its self-funded employers to adopt the waivers.

Anthem has also taken other steps similar to its peers in the industry, such as waiving the cost-sharing for testing and tele-health, and easing prescription limits.

Aetna, Cigna and Humana all previously announced they would waive members’ cost-sharing for COVID-19 treatment. These insurers also waived copayments and other cost-sharing for testing and telehealth visits.

Regional health plans are taking similar steps. Florida Blue announced Tuesday it would waive cost-sharing for treatment, as did Harvard Pilgrim Health Plan.
