Where the denial was upheld

Worth reading too — these show what an appeal has to overcome.
Nature of Statutory Criteria/Case Summary: The patient has requested reimbursement for air ambulance services provided by Critical Care Medflight. Functional impairments due to traumatically acquired brain insults can be profound, particularly in the setting of severe injuries and in the setting of intracerebral hemorrhage. Eapen and colleagues note that traumatic brain injury (TBI) sequelae can lead to long-term impairments in physical, cognitive, behavioral, and social function. Per the authors, TBI rehabilitation requires an interdisciplinary holistic team approach in the management of medical complications, the prevention of further disability, and helping patients return to their highest level of independence. While there is some natural recovery following acute TBI, the impairments associated with this condition are also generally amenable to various rehabilitation interventions.
