Growth in the availability of cell and gene therapies (CGTs) promises significant innovation in the treatment of serious diseases, but the high cost and one-time administration of CGTs has also raised concern about strain on health plan budgets and inequity in access. We used coverage information from the Tufts Medical Center Specialty Drug Evidence and Coverage (SPEC) database for 18 large commercial health plans in the US and information from state Medicaid websites to examine variation in coverage of 11 CGTs. We conclude that there is variation in access to CGTs, creating differential patient access.
