CMS Pub. 100-16, ch. 4, § 20.3
MAO Responsibilities for Coverage of Emergency Services
The MAO must inform enrollees of their right to call 911 and:
• No materials furnished to enrollees, including wallet card instructions, may contain
instructions to seek prior authorization for emergency or urgently needed services;
and
• No materials furnished to providers, including contracts, may contain instructions to
providers to seek prior authorization before the enrollee has been stabilized.
The MAO is financially responsible for emergency services and urgently needed
services:
• Regardless of whether services are obtained within or outside the plan’s authorized
service area and/or network (if applicable);
• Regardless of whether there is prior authorization for the services;
• If the emergency situation is in accordance with a prudent layperson’s definition of
“emergency medical condition,” regardless of the final medical diagnosis; and
• Whenever a plan provider - a provider with whom the MAO has a written contract to
furnish plan covered services to its enrollees - or other plan representative instructs an
enrollee to seek emergency services within or outside the plan.
The MAO is not responsible for the care provided for an unrelated non-emergency
problem during treatment for an emergency situation. For example, if the attending
physician is treating a fracture, the plan is not responsible for any costs connected with a
biopsy of skin lesions performed while treating the facture.
