Mental health services in managed care: quality questions remain.

Primary care physicians are often the professionals to whom older patients turn for advice about medical coverage in Medicare managed care health plans. To assist in this dialogue, these authors outline current characteristics and financial arrangements for psychiatric and mental health services in Medicare managed care. Advantages and disadvantages of Medicare managed care for enrollees with mental disorders are outlined. Mental health "carve-out" and "carve-in" models are defined, and questions are raised about the number of psychiatrists and other mental health care providers needed to provide appropriate care for a plan's enrollees.
