Insurance, Health, Accident - As introduced, increases, from 60 to 65 days prior to the effective date of the change, the required minimum notice that a health insurance entity must provide to a healthcare provider of any material change made in the sole discretion of the insurance entity to the entity's previously released provider manual or a reimbursement rule and policy. - Amends TCA Title 56, Chapter 7.

HB 2579 amends Tennessee law to require health insurance companies to provide healthcare providers with 65 days' notice - up from 60 days - before implementing any material changes to their provider manuals or reimbursement policies. This change directly affects healthcare providers who rely on timely notice to adjust billing, care coordination, and practice operations. The bill modifies Tennessee Code Annotated § 56-7-3302(a)(1) to extend the notice period, ensuring providers have slightly more time to prepare for insurer policy updates.
