Clinical Information
  • Condition in which there is a deviation from or interruption of the normal structure or function of the parasympathetic or sympathetic divisions of the autonomic nervous system; autonomic dysfunction may be associated with hypothalamic diseases, brain stem disorders, spinal cord diseases, and peripheral nervous system diseases; manifestations include impairments of vegetative functions including the maintenance of blood pressure, heart rate, pupil function, sweating, reproductive and urinary physiology, and digestion.
  • Diseases of the parasympathetic or sympathetic divisions of the autonomic nervous system; which has components located in the central nervous system and peripheral nervous system. Autonomic dysfunction may be associated with hypothalamic diseases; brain stem disorders; spinal cord diseases; and peripheral nervous system diseases. Manifestations include impairments of vegetative functions including the maintenance of blood pressure; heart rate; pupil function; sweating; reproductive and urinary physiology; and digestion.
  • Your autonomic nervous system is the part of your nervous system that controls involuntary actions, such as the beating of your heart and the widening or narrowing of your blood vessels. When something goes wrong in this system, it can cause serious problems, including
    • blood pressure problems
    • heart problems
    • trouble with breathing and swallowing
    • erectile dysfunction in men
    autonomic nervous system disorders can occur alone or as the result of another disease, such as parkinson's disease, alcoholism and diabetes. Problems can affect either part of the system, as in complex regional pain syndromes, or all of the system. Some types are temporary, but many worsen over time. When they affect your breathing or heart function, these disorders can be life-threatening.some autonomic nervous system disorders get better when an underlying disease is treated. Often, however, there is no cure. In that case, the goal of treatment is to improve symptoms.

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 337.9 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
