2020 ICD-10-CM Diagnosis Code G81

Hemiplegia and hemiparesis

    2016 2017 2018 2019 2020 Non-Billable/Non-Specific Code
  • G81 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
  • The 2020 edition of ICD-10-CM G81 became effective on October 1, 2019.
  • This is the American ICD-10-CM version of G81 - other international versions of ICD-10 G81 may differ.
Note
  • This category is to be used only when hemiplegia (complete)(incomplete) is reported without further specification, or is stated to be old or longstanding but of unspecified cause. The category is also for use in multiple coding to identify these types of hemiplegia resulting from any cause.
Type 1 Excludes
Type 1 Excludes Help
A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as G81. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

    Diseases of the nervous system
Clinical Information
  • Paralysis of one side of the body resulting from disease or injury to the brain or spinal cord.
  • Paralysis of one side of the body.
  • Severe or complete loss of motor function on one side of the body. This condition is usually caused by brain diseases that are localized to the cerebral hemisphere opposite to the side of weakness. Less frequently, brain stem lesions; cervical spinal cord diseases; peripheral nervous system diseases; and other conditions may manifest as hemiplegia. The term hemiparesis (see paresis) refers to mild to moderate weakness involving one side of the body.
