Called 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 nurse care with a physician’s availability for significant problems in Dimensions 1, 2, or 3. Patients in this level of care need medication and have a recent background of withdrawal management at a less intensive level of care, marked by previous and current inability to complete withdrawal management and become part of continuing substance addiction treatment. This is the suitable setting for patients with subacute biomedical and mental, behavioral, or cognitive problems that are so intense that they require inpatient treatment. Level 3 includes residential services that are referred to 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 range of services in a 24-hour treatment setting.
