104 CMR 28.16
Community Crisis Stabilization Services for Adults (ACS)
(1) Adult Crisis Stabilization (ACS) is a sub-acute community-based mental health treatment
service for adults with mental illness, substance use disorder or comorbid mental illness and
substance use disorders who are in need of staff-secure, safe and structured short-term crisis
stabilization and treatment in a 24-hour unlocked community treatment setting. ACS serves as
a medically necessary, less restrictive and voluntary alternative to inpatient psychiatric
hospitalization. Although this service is primarily designed as an alternative to and diversion
from inpatient care, it may also be used as a transition from an inpatient setting, provided there
is sufficient capacity, and the admission criteria are met.
(2) The primary objective of ACS is to restore or improve functioning; strengthen the resources
and capacities of the person served and family or other natural supports; provide a timely return
to a natural, least restrictive setting; develop a crisis/safety and wellness/recovery plan; and
facilitate linkages to medically necessary services and supports. While the anticipated length of
stay for this service is seven days or less, a person's actual length of stay is based on the
documented clinical assessment.
(3) Minimum service components shall include crisis prevention, stabilization and treatment
by a multidisciplinary team; initial and continuing bio-psychosocial assessment; care
coordination; psychiatric evaluation and medication management, including bridging and
induction onto FDA approved medication(s) to treat opioid use disorder (MOUD) as clinically
appropriate; peer support and/or other recovery-oriented services including relapse prevention
and recovery maintenance counseling and education; mobilization of and coordination with
family and other natural supports, community treaters, and other resources; and
psycho-education, including providing education and information about recovery, wellness, crisis
self-management, and how to access wellness and recovery services available in the person's
specific community.
(4) Admission Criteria. Persons who meet the following criteria may be admitted to an adult
Class I licensed service:
(a) The person must be 18 years of age or older.
(b) The person must demonstrate symptoms consistent with a diagnosis specified within the
current edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM), which
can reasonably be expected to respond to short term, structured treatment intervention.
