MHCM Medical Necessity Criteria-Continued Stay Criteria:  Previously MH Case Management was a registration-only service due to the population served.  Our MH Case Managers serve individuals with serious, persistent, chronic mental illness who often rely on these services to maintain baseline and avoid the need to access higher, more expensive levels of care.  By requiring multiple re-assessments and discharge if an individual does not continually demonstrate progress could lead to individuals not receiving this vital service to remain stable at baseline.
