Clinical InformationClinical
Alien Limb Phenomenon
an apraxia characterized by the affected limb having involuntary, autonomous, and seemingly purposeful behaviors that are perceived as being controlled by an external force. often the affected limb interferes with the actions of the normal limb. symptoms develop from lesions in the corpus callosum or medial frontal cortex caused by stroke, infarction, and neurodegenerative diseases (e.g., creutzfeldt-jakob syndrome, corticobasal degeneration).
Patient EducationClinical

Code HistoryHistory
Questions About R41.4Overview
Is R41.4 a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report neurologic neglect syndrome on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
Can R41.4 be a principal diagnosis?
Use it with care. This is a symptom code, so once a definitive diagnosis explaining the neurologic neglect syndrome is established, that condition takes the principal position instead.
What is the ICD-9 equivalent of R41.4?
Under the General Equivalence Mappings, neurologic neglect syndrome converts to ICD-9-CM 781.8 (neurologic neglect syndr). The mapping is a direct match.
Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
