Concerning rapid whole genome sequencing.

HB 1444 requires Washington health insurers to cover rapid whole genome sequencing for infants under one year old in intensive care units who meet specific medical criteria, such as unexplained epilepsy, multiple congenital abnormalities, or suspected genetic disorders. It mandates coverage starting January 1, 2026, for cases where timely diagnosis is critical to treatment, including pre- and post-test counseling. The bill ensures separate payment for this service (not bundled into existing hospital payments) and defines "rapid" sequencing as delivering results in under 14 days. It directly affects low-income families enrolled in medical assistance programs by removing financial barriers to faster diagnosis of rare genetic conditions.
