American Society of Addiction Medicine (ASAM) Criteria Practice Test 2025 - Free ASAM Criteria Practice Questions and Study Guide

The level of ASAM care that involves 20 or more hours of service weekly is accurately identified as Level II.5. This level, known as Partial Hospitalization Program (PHP), is designed for individuals who require substantial treatment but do not need round-the-clock supervision found in more intensive services.

Level II.5 typically involves a structured schedule with highly intensive therapeutic services delivered on a part-time basis, which meets the criteria of 20 or more hours of service each week. This kind of care is aimed at individuals who are experiencing significant functional impairment and need more structured support than outpatient settings can provide, but who can still maintain some degree of independence.

In contrast, Level III.3 typically involves a higher level of care such as clinically managed residential services, which is more intensive than Level II.5. Level I represents outpatient services and would typically involve far fewer hours of direct service per week. Level IV represents medically managed intensive inpatient services, which also does not reflect the hour requirement set out in the question.
