G90 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity from the list below for a diagnosis of disorders of autonomic nervous system. The code is not specific and is NOT valid for the year 2026 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.
Non-specific codes like G90 require more digits to indicate the appropriate level of specificity. Consider using any of the following billable codes with a higher level of specificity when coding for disorders of autonomic nervous system:
G90.0 for Idiopathic peripheral autonomic neuropathy
Use G90.01 for Carotid sinus syncope
Use G90.09 for Other idiopathic peripheral autonomic neuropathy
Use G90.1 for Familial dysautonomia [Riley-Day]
Use G90.2 for Horner's syndrome
Use G90.3 for Multi-system degeneration of the autonomic nervous system
Use G90.4 for Autonomic dysreflexia
G90.5 for Complex regional pain syndrome I (CRPS I)
Use G90.50 for Complex regional pain syndrome I, unspecified
G90.51 for Complex regional pain syndrome I of upper limb
G90.52 for Complex regional pain syndrome I of lower limb
Use G90.59 for Complex regional pain syndrome I of other specified site
G90.8 for Other disorders of autonomic nervous system
Use G90.81 for Serotonin syndrome
Use G90.89 for Other disorders of autonomic nervous system
Use G90.9 for Disorder of the autonomic nervous system, unspecified
Use G90.A for Postural orthostatic tachycardia syndrome [POTS]
Use G90.B for LMNB1-related autosomal dominant leukodystrophy

G00–G99
Autonomic Nervous System Disorders
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.
