This bill amends the Maine Insurance Code in the following ways. 1. It allows a health care provider to object to a health insurance carrier’s material change to a provider agreement within 60 days of receiving notice of the change and extends the date on which a change to a provider agreement takes effect based on that objection. 2. It requires a health insurance carrier to include an estimate of any adverse financial impact on a provider as part of a notice of an amendment to a provider agreement. 3. It clarifies that the requirement for interest to be paid on overdue insurance claims payments also applies to 3rd-party administrators that furnish provider networks to carriers. 4. It restricts the authority of a health insurance carrier to retroactively deny a previously paid claim to no later than 24 months from the date of the claims payment.
