Mental Disorders and Behavioral Disorders (Chapter 5)

Mental health conditions and behavioral disorders can be caused by issue during fetal development, genetic factors, chemical imbalances, environmental factors, psychoactive substance abuse, and physiological conditions.

General Guidelines

  • When a condition is considered to be "in remission," categories F10-F19, they require the use of -.21. 

  • If a patient has pain that is reported as psychological, the coder should assign code F45.41. 

  • If insomnia is due to a mental health disorder or behavioral condition, the coder should assign code F51.05, followed by a code that identifies the specific mental disorder. 

  • When a patient has a speech and language development delay due to hearing loss, the coder should identify the type of hearing loss with a secondary code. 

  • If delirium is due to a known physiological condition, the coder should code first the underlying condition, followed by F05, Delirium due to known physiological condition (Davis, 2011; Grebner & Suarez, 2013). 

Diseases of the Nervous System (Chapter 6)

There are many central nervous system disorders and diseases that affect extrapyramidal movement. These include inflammatory diseases, degenerative disorders, demyelinating diseases, and systemic atrophies. In ICD-10-CM Chapter 6 "Diseases of the Nervous System," the code categories are G00-G99. 

  • G00-G09 Inflammatory Disease of the Central Nervous System – Codes in this subsection correspond with those in categories 320-326 in ICD-9-CM. Conditions coded include encephalitis, meningitis, encephalopathy, intracranial and intraspinal abscesses, granulomas, and phlebitis, and sequelae of inflammatory diseases. 

  • G10-G14 Systemic Atrophies Primarily Affecting the Central Nervous System - Codes in this subsection correspond with those in categories 333-335 in ICD-9-CM. Conditions coded include hereditary ataxias, Huntington's disease, spinal muscular atrophies, and systemic atrophies. 

  • G20-G26 Extrapyramidal and Movement Disorders - Codes in this subsection correspond with those in categories 331-333 in ICD-9-CM. Conditions coded include degenerative basal ganglia diseases, extrapyramidal disorders, Parkinson's disease, and movement disorders.

  • G30-G32 Other Degenerative Diseases of the Nervous System - Codes in this subsection correspond with those in categories 330, 331, and 336 in ICD-9-CM. Conditions coded include Alzheimer's disease and degenerative nervous system disorders. 

  • G35-G37 Demyelinating Diseases of the Central Nervous System - Codes in this subsection correspond with those in categories 323 and 340 in ICD-9-CM. Conditions coded include multiple sclerosis and other demyelinating conditions. 

  • G40-G47 Episodic and Paroxysmal Disorders - Codes in this subsection correspond with those in categories 345-347 in ICD-9-CM. Conditions coded include migraines, epilepsy, headaches, transient ischemic attacks, vascular syndromes of the brain, and sleep disorders. 

  • G50-G59 Nerve, Nerve Root, and Plexus Disorders - Codes in this subsection correspond with those in categories 350-355 in ICD-9-CM. Conditions coded include cranial nerve disorders, mononeuropathies, nerve root diseases, and plexus disorders. 

  • G60-G65 Polyneuropathies and Other Disorders of the Peripheral Nervous System - Codes in this subsection correspond with those in categories 356-359 in ICD-9-CM. Conditions coded include hereditary neuropathies, inflammatory polyneuropathies, idiopathic neuropathies, disorders of the peripheral nervous system, and sequelae of inflammatory and toxic polyneuropathies. 

  • G70-G73 Diseases of Myoneural Junction and Muscle - Codes in this subsection correspond with those in categories 358-359 in ICD-9-CM. Conditions coded include myoneural disorders, muscular dystrophy, myasthenia gravis, myopathies, and disorders of the myoneural junction and muscles.

Conditions coded include pain disorders, autonomic nervous system conditions, hydrocephalus, brain disorders, spinal cord conditions, and other central nervous system disorders (Grebner & Suarez, 2013). 

General Guidelines

  • When the coder must provide more detail about acute or chronic pain, or neoplasm-related pain, codes in the category G89, Pain, not elsewhere classified can be used along with other codes. 

  • When the reason for the encounter is pain management or control rather than treatment of the underlying condition, the coder can assign G89. 

  • Avoid the use of G89.0, Central pain syndrome and G89.4, Chronic pain syndrome unless the provider has specifically documented this as a diagnosis. 

  • When coding G09, Sequelae of inflammatory disease of central nervous system, the coder should first assign a code for the residual condition, followed by G09 as a secondary code. 

  • All codes in category G13 should be used as secondary codes, following assignment of underlying disease and/or neoplasms (Davis, 2011; Grebner & Suarez, 2013).
