Where the denial was overturned

Nature of Statutory Criteria/Case Summary: The parent of an enrollee has requested reimbursement for inpatient hospitalization services. The Health Plan has denied this request indicating that the services at issue were not medically necessary for treatment of the enrollee’s behavioral health conditions. This patient was admitted to the inpatient unit due to possible suicidal ideation and issues with relationships and inappropriate behaviors on the internet. On an initial evaluation, the patient reported some possible passive suicidal ideation. This passive suicidal ideation appeared to abate after her first day in the hospital. She did not have any active suicidal ideation or plans to harm herself and did not make any attempts to harm herself or others during her hospital stay.
