AZ HB2476

Amends Arizona law to establish prima facie claims for workers' compensation related to methicillin-resistant staphylococcus aureus (MRSA), spinal meningitis, and tuberculosis for covered employees including firefighters, law enforcement officers, corrections officers, probation officers, EMTs, and paramedics.

Requires employees to report significant exposure in writing to their employer within thirty calendar days (changed from ten days) after possible exposure, with employers required to notify their insurance carrier.

For MRSA claims, employees must be diagnosed within fifteen days after reporting the exposure (changed from "two to ten days of the possible significant exposure").

Establishes that employers may dispute prima facie claims by presenting specific evidence about the exposure or establishing alternative significant exposure sources.

Provides that post-exposure evaluation, follow-up care, and prophylactic treatment for spinal meningitis and tuberculosis are covered medical benefits without constituting acceptance of the underlying disease claim.
