Code Classification

  • Diseases of the nervous system
    (G00–G99)
    • Cerebral palsy and other paralytic syndromes
      (G80-G83)
      • Hemiplegia and hemiparesis
        (G81)

G81.9 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of hemiplegia, unspecified. The code is not specific and is NOT valid for the year 2024 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.

Unspecified diagnosis codes like G81.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Specific Coding Applicable to Hemiplegia, unspecified

Non-specific codes like G81.9 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for hemiplegia, unspecified:

  • Use G81.90 for Hemiplegia, unspecified affecting unspecified side - BILLABLE CODE

  • Use G81.91 for Hemiplegia, unspecified affecting right dominant side - BILLABLE CODE

  • Use G81.92 for Hemiplegia, unspecified affecting left dominant side - BILLABLE CODE

  • Use G81.93 for Hemiplegia, unspecified affecting right nondominant side - BILLABLE CODE

  • Use G81.94 for Hemiplegia, unspecified affecting left nondominant side - BILLABLE CODE

Clinical Information
