The main purpose of this legislation is to remove the 190-day lifetime limit on inpatient psychiatric hospital services for individuals covered by Medicare. This change aims to improve access to necessary mental health care for those who may require extended treatment in psychiatric facilities. Key provisions of the legislation include the complete elimination of the 190-day cap on inpatient psychiatric services under Medicare. This means that patients will no longer be restricted to a maximum of 190 days of inpatient care over their lifetime.
