Code Classification

  • Mental and behavioural disorders
    (F01–F99)
    • Mental disorders due to known physiological conditions
      (F01-F09)
      • Unspecified dementia
        (F03)

F03.918 is a billable diagnosis code used to specify a medical diagnosis of unspecified dementia, unspecified severity, with other behavioral disturbance. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

The code F03.918 is applicable to adult patients aged 15 through 124 years inclusive. It is clinically and virtually impossible to use this code on a patient outside the stated age range.

Unspecified diagnosis codes like F03.918 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.
