The Accredited Case Manager (ACM) credential is administered by the American Case Management Association (ACMA) and is one of the two leading case management certifications alongside the CCM. Unlike generalist case management credentials, the ACM is built specifically around hospital and health system case management practice, and is offered in two tracks — ACM-RN for registered nurses and ACM-SW for social workers — each tested on the same core content but with role-relevant scenario simulations.
Who it's for
Registered nurses and social workers working (or preparing to work) as case managers, care coordinators, or transition planners inside hospitals, health systems, and acute or post-acute care settings. Candidates must have at least 2,080 hours (about 12 months full-time) of supervised, paid experience specifically in a case manager role, on top of a current RN license or qualifying social work degree/license.
What's covered
- Screening and Assessment — identifying patients who need case management, biopsychosocial-spiritual assessment, functional and cognitive screening, and risk stratification for readmission and adverse outcomes.
- Planning — building an individualized case management plan, setting patient-centered goals, determining appropriate level of care, and coordinating utilization management and payer requirements.
- Care Coordination and Intervention — the largest domain: coordinating across the interdisciplinary team, patient/family education, community resource linkage, transitional care, utilization review, denials and appeals, and regulatory compliance (CMS Conditions of Participation, EMTALA, HIPAA).
- Evaluation — measuring outcomes, monitoring plan effectiveness, cost and quality metrics, variance analysis, and case closure.
What to expect
The exam has two parts — a core multiple-choice section and a scenario-based simulation section reflecting the candidate's discipline (nursing or social work) — delivered in a randomized order, with a combined 120-minute time limit and roughly 100 scored questions. Both sections must be passed; candidates who pass only one section have a 6-month window to retake and combine scores.
How to prepare
Because the ACM leans heavily on real hospital workflow rather than abstract theory, the exam rewards familiarity with the actual case management process (screen, assess, plan, implement/coordinate, monitor, evaluate) and how it plays out across a real admission — from screening at intake through discharge planning and post-acute handoff. Utilization review concepts (medical necessity, level-of-care criteria, concurrent review, denials/appeals) and regulatory basics (EMTALA, CMS Conditions of Participation, HIPAA) show up throughout Care Coordination and Intervention, which carries the heaviest weight on the exam.
