In the recently released IPPS Proposed Rule, CMS is proposing to modify its regulations that allow payment for ambulance services furnished by a CAH or by an entity owned and operated by the CAH based on 101 percent of reasonable costs rather than the ambulance fee schedule to conform with language in the Medicare law and also to make provision of reasonable cost payment to an entity owned and operated by a CAH that is further than 35 miles from the CAH, if it is the closest provider or supplier of ambulance services to the CAH.
