A New York financial regulator is probing allegations that some life and disability insurers are  denying coverage to applicants who use pre-exposure prophylactic medication meant to reduce the risk of HIV infection in adults.

Department of Financial Services Superintendent Maria Vullo said Wednesday that the department, which regulates banks and insurance companies operating in the state, would investigate the insurance companies after a report by The New York Times that some gay men who had used PrEP medication—approved by the U.S. Food and Drug Administration to reduce the risk of acquiring the virus that causes AIDS—had been turned down for life and disability insurance policies across the United States.
