(a) Every insurer shall provide coverage for emergency medical services, including prehospital services, to the extent necessary to screen and to stabilize an emergency medical condition. The insurer shall not require prior authorization of the screening services if a prudent layperson acting reasonably would have believed that an emergency medical condition existed. Prior authorization of coverage shall not be required for stabilization if an emergency medical condition exists. Payment of claims for emergency services shall be based on the retrospective review of the presenting history and symptoms of the covered person.
(b) An insurer that has given prior authorization for emergency services shall cover the services and shall not retract the authorization after the services have been provided unless the authorization was based on a material misrepresentation about the covered person's health condition made by the referring provider, the provider of the emergency services or the covered person.
(c) Coverage of emergency services shall be subject to coinsurance, copayments and deductibles applicable under the health benefit plan.
(d) The emergency department and the insurer shall make a good faith effort to communicate with each other in a timely fashion to expedite postevaluation or poststabilization services in order to avoid material deterioration of the covered person's condition.
