MODERATE
HB 584 was amended to clarify the requirements for dentists administering anesthesia and sedation. The bill now explicitly requires facilities providing deep sedation, general anesthesia, or moderate sedation to have specific minimum equipment, supplies, and drugs for administering these services, rather than just for nitrous oxide. Additionally, the inspection requirements were updated to mandate a reinspection every five years and clarified that initial inspections must be conducted by board-appointed inspectors with 30 days' notice.
Scope change
The bill's scope regarding facility safety standards was expanded to cover a broader range of anesthesia services beyond just nitrous oxide administration.
REQUIREMENT

Updated facility standards to require minimum equipment and supplies for administering deep sedation, general anesthesia, or moderate sedation, expanding previous requirements that focused only on nitrous oxide.

Mandated that re-inspections of facilities must occur at intervals not to exceed five years.

Added a specific provision allowing the board to grant temporary permits to licensed dentists upon receipt of an application and payment of the initial inspection fee.

ENFORCEMENT

Clarified that initial inspections must be performed by an inspector appointed by the board, and applicants must receive at least 30 days' notice before the inspection.
