2013 ICD-9-CM Diagnosis Code 331.0 : Alzheimer's disease

neurodegenerative disorder of the CNS resulting in progressive loss of memory and intellectual functions; begins in the middle or later years; characterized by brain lesions such as neurofibrillary tangles and neuritic plaques.
A disabling degenerative disease of the nervous system occurring in middle-aged or older persons and characterized by dementia and failure of memory for recent events, followed by total incapacitation and death. Types of the Alzheimer syndrome are differentiated by the age of onset and genetic characteristics. The early onset form (the mean age of the onset of symptoms between the ages of 40 and 60 years) and the late onset form (the onset of symptoms after the age of 60 years). Three forms are identified: AD-1, AD-2, AD-3. Some of the clinical characteristics of the Alzheimer syndrome are similar to those of the Pick syndrome.
A progressive, neurodegenerative disease characterized by loss of function and death of nerve cells in several areas of the brain leading to loss of cognitive function such as memory and language.
ICD-9-CM 331.0 is a billable medical code that can be used to specify a diagnosis on a reimbursement claim.
