Plain-language change summary

The updated version of Bill HB 1850 adds specific definitions and requirements regarding audits conducted by pharmacy benefits managers (PBMs) and other entities. Notably, it clarifies what constitutes an audit and stipulates that pharmacies must receive a 14-day notice before an audit occurs, instead of the previously proposed one-week notice. These changes aim to protect pharmacies by ensuring they have adequate time to prepare for audits, which can have significant financial implications for them.
