Dizziness and giddiness

This code represents a general sensation of unsteadiness, lightheadedness, or a feeling of being about to faint, without a rotational component. It describes a non-specific symptom that can arise from various underlying conditions, often impacting balance and spatial orientation.

Use this code when documentation indicates a patient experiences dizziness or giddiness that is not specifically described as vertigo (a sensation of spinning or rotational movement). This code is appropriate when the cause of the dizziness is unknown or when it is a symptom of a systemic condition rather than a vestibular disorder.

• Always attempt to code the underlying cause of the dizziness if known and documented.
• Distinguish carefully between "dizziness" (R42) and "vertigo" (H81.-), as these are mutually exclusive per Excludes1 notes.
• Avoid using this code as a primary diagnosis if a more specific diagnosis explaining the dizziness is available.
