In March and April 2020, mental health claim lines for individuals aged 13-18, as a percentage of all medical claim lines, approximately doubled over the same months in the previous year. At the height of the spring wave of the COVID-19 pandemic, this rise in mental health claim lines amounted to 97.0 percent in March and 103.5 percent in April. These are among the many findings in FAIR Health’s new white paper, the seventh in its COVID-19 studies, The Impact of COVID-19 on Pediatric Mental Health: A Study of Private Healthcare Claims.
