Termed the Medically Monitored High-Intensity Inpatient Services for adolescents and Medically Monitored Intensive Inpatient Services Withdrawal Management for adults, this particular level of care provides 24-hour nursing care with a physician’s availability for significant problems in Dimensions 1, 2, or 3. Patients within this level of care need medication and have a recent history of withdrawal management at a less intensive level of care, marked by previous and current inability to complete withdrawal management and enter into continuing substance addiction treatment. This is the suitable setting for patients with subacute biomedical and emotional, behavioral, or intellectual problems that are so extreme that they require inpatient treatment. Level 3 includes residential services that are described as co-occurring capable, co-occurring enhanced, and complexity capable services, which are staffed by designated addiction treatment, mental health, and general medical personnel who provide a variety of services in a 24-hour treatment setting.
