Creates provisions relating to insurance coverage of anesthesia services

HB 1126 requires health insurers and state health plans to pay for all anesthesia time during medical procedures without imposing time limits or excluding any anesthesia time from payment calculations. It directly affects anesthesia providers (like anesthesiologists) and health carriers (including Medicaid managed care organizations and MO HealthNet) by mandating that payment must be based on the full time an anesthesia practitioner is actively providing care to a patient. The bill prohibits insurers from establishing policies that restrict or exclude any portion of "anesthesia time" - defined as the continuous period from preparation through post-anesthesia care - when calculating payments. This ensures providers are compensated for the full duration of their service, aligning payment with actual clinical time rather than arbitrary limits.
