provides that a contracted entity that uses a prior authorization process for health care services may not require a participating provider to obtain prior authorization for a particular health care service if, in the most recent 6-month evaluation period the contracted entity has approved or would have approved not less than 90% of the prior authorization requests submitted by the provider for the particular health care service. Contracted entities may evaluate participating providers to determine whether the provider qualifies for the exemption. The exemption shall remain in effect until the 13th day after the date the contracted entity notifies the provider of the contracted entity’s determination to rescind the exemption, though the provider may appeal the decision. Contracted entities may only rescind exemptions under certain conditions outlined in the measure. If the appeal carries through, the contracted entity is prohibited from rescinding the exemption until the next evaluation period. A contracted entity may not retroactively deny a health care service on the basis of a rescission of an exemption.
