Therefore, this code may be out of date. The 2009 version of ICD-9-CM 253.6 can be accessed here. Abnormal secretion of antidiuretic hormone in conjunction with neoplastic growth occurring anywhere in the body. Hyponatremia and renal salt loss attributed to overexpansion of body fluids resulting from sustained release of VASOPRESSINS (i.e., antidiuretic hormone) despite the absence of appropriate stimuli. Associated conditions include medication effect; MENINGITIS; CRANIOCEREBRAL TRAUMA; ENCEPHALITIS; CEREBROVASCULAR DISORDERS; HYDROCEPHALUS; PNEUMONIA; ASTHMA; THYROID DISEASES; and other conditions. This condition may also be idiopathic or result from ectopic (extra-pituitary) production of ADH.
