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 authorization and coverage for continued acute rehabilitation with neurology and cardiology follow up, as deemed necessary by the current inpatient treating neurologist and cardiologist, as well as one hour of occupational therapy, speech therapy, and physical therapy Monday through Friday. Functional impairments due to a cerebral stroke, whether ischemic or hemorrhagic, can be severe to profound. The extent of initial injury is oftentimes a major determinant of functional outcomes (Alawieh, et al.). Most of a patient’s significant neurological and functional recovery occurs in the early stages after a stroke and gains are slower to come in the subsequent stages (Kubis). Initiating intensive rehabilitative measures earlier in the post-stroke course has been shown to enhance patient health outcomes.

Nature of Statutory Criteria/Case Summary: The patient has requested reimbursement and prospective authorization and coverage skilled nursing facility (SNF) services and acute rehabilitation level of care services. Minor spontaneous spinal hematomas occurring in the thoracic spine may be managed with observation and conservative measures. However, larger spinal hematomas with significant neurological compromise generally require surgical intervention with spinal decompression and hematoma evacuation. Functional impairments related to residual paraplegia and neurogenic bowel and bladder require complex, individualized rehabilitative measures. This patient’s records document that she developed acute paraparesis due to a hematoma following anticoagulation for a pulmonary embolus. The patient underwent spinal decompression and hematoma evacuation.
