Allows injured employees to authorize their primary treating physician to request electronic copies of notifications regarding medical provider network (MPN) eligibility or required treatment transfers.

Expands MPN rosters to include all physicians and permits inclusion of entities providing ancillary services, management services, or patient care coordination, replacing previous detailed listing requirements.

Requires the administrative director to provide applicants 45 calendar days to submit additional information if an MPN plan is disapproved or contains deficiencies, with a required director response within 30 days.

Clarifies that employers and insurers have the right to determine network members including duly licensed physicians within their scope of practice and ancillary service providers regardless of business entity type.

Establishes that approved MPN plans remain valid during the reapproval process for timely submitted renewal applications.
