Prohibits health carriers from requiring prior authorization of inpatient psychiatric hospital services

HB 1927 prohibits Missouri health insurance plans from requiring prior authorization (pre-approval) for inpatient psychiatric hospital services. This bill directly affects patients seeking psychiatric hospitalization and health insurers who currently must approve such care before coverage. The key provision removes the requirement for insurers to review and approve inpatient psychiatric care in advance, streamlining access to treatment. It applies specifically to inpatient psychiatric hospital services, not other types of care or outpatient treatment. The bill repeals existing prior authorization rules for this service under Missouri law.
