Expedited / Urgent Request Guidelines
?
CMS defines an expedited or urgent request as a request in which waiting for a decision under the standard time frame could place the member's life, health, or ability to regain maximum function in serious jeopardy. Contracted providers should submit requests in accordance with CMS guidelines to allow for organization determinations within the standard turnaround time, unless the member urgently needs care based on the CMS definition of an expedited or urgent request.
