ICD-10-CM › G00-G99 › G80-G83 › G81 Hemiplegia and hemiparesis › G81.0

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 5 more specific codes instead:

• G81.00 Flaccid hemiplegia affecting unspecified side
• G81.01 Flaccid hemiplegia affecting right dominant side
• G81.02 Flaccid hemiplegia affecting left dominant side
• G81.03 Flaccid hemiplegia affecting right nondominant side
• G81.04 Flaccid hemiplegia affecting left nondominant side

What has happened to this code

Official coding rules

Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.

Inherited from G81 Hemiplegia and hemiparesis

Excludes1 - never coded here

• congenital cerebral palsy (G80.-)
• hemiplegia and hemiparesis due to sequela of cerebrovascular disease (I69.05-, I69.15-, I69.25-, I69.35-, I69.85-, I69.95-)

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.

How CDC's index refers to this code

• Hemiparesis
• Hemiparalysis
• Mills' disease
• Paralysis, paralytic > left side
• Paralysis, paralytic > hemiplegic
• Paralysis, paralytic > right side
