105 CMR, § 164.101
24-hour Diversionary Services medically manage withdrawal symptoms of patients on a 24-hour diversionary service basis, and include 24-hour diversionary service forms of Acute Treatment Services (ATS) and Clinical Stabilization Services (CSS). Acute Treatment Services encourage the patient's continued participation in treatment after discharge, and conclude by directly connecting the patient to appropriate recovery and rehabilitation services. In addition to all provisions of 105 CMR 164.000: Part One, the provisions of 105 CMR 164.103 through 105 CMR 164.110 apply to all Licensed or Approved Providers providing 24-hour Diversionary Services. A Licensed or Approved Provider that meets the requirements for a determined service type under 105 CMR 164.100 through 105 CMR 164.153 may also deliver services to lower acuity patients, provided that the Licensed or Approved Provider meets all applicable staffing and service requirements for each additional service type.
