Preamble - Principles of Medical Necessity Determinations Individualized, Needs-Based, Least-Restrictive Treatment Magellan1 is committed to the philosophy of providing treatment at the most appropriate, least-restrictive level of care necessary to provide safe and effective treatment and meet the individual patient’s biopsychosocial needs. We see the continuum of care as a fluid treatment pathway, where patients may enter treatment at any level and be moved to more or less-intensive settings or levels of care as their changing clinical needs dictate. At any level of care, such treatment is individualized, active and takes into consideration the patient’s stage of readiness to change/readiness to participate in treatment. The level of care criteria that follow are guidelines for determining medical necessity for the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5™) disorders. Individuals may at times seek admission to clinical services for reasons other than medical necessity, e.g., to comply with a court order, to obtain shelter, to deter antisocial behavior, to deter runaway/truant behavior, to achieve family respite, etc. However, these factors do not alone determine a medical necessity decision. Further, coverage for services is subject to the limitations and conditions of the member benefit plan. Specific information in the member’s contract and the benefit design for the plan dictate which medical necessity criteria are applicable. Although these Medical Necessity Criteria Guidelines are divided into “psychiatric” and “substance-related” sets to address the patient’s primary problem requiring each level of care, psychiatric and substance-related disorders are often co-morbid. Thus, it is very important for all treatment facilities and providers to be able to assess these co-morbidities and address them along with the primary problem.
