Medicare Part B covers ambulance services to or from a hospital or skilled nursing facility. Medicare covers and helps pay for ambulance services only when other transportation could endanger your health due to your medical condition. This coverage applies only to ambulance transportation to the nearest medical facility that’s able to provide the care you need.
Medicare Part B also covers:
Emergency ambulance transportation when you have a sudden medical emergency and you can’t be safely transported by other means, such as car or taxi
Emergency ambulance transportation in an airplane or helicopter if your health condition requires immediate and rapid transport
Non-emergency ambulance transportation if your doctor provides a written order that ambulance transportation is medically necessary
