Polydipsia

This code signifies the medical condition of excessive thirst, a symptom that can indicate various underlying physiological imbalances. It describes an abnormally high fluid intake driven by a persistent sensation of thirst.

Assign this code when documentation explicitly states "polydipsia" or "excessive thirst" as a presenting symptom or a diagnosed condition. This is often seen in patients with uncontrolled diabetes mellitus, diabetes insipidus, or certain psychiatric conditions.

• Do not code polydipsia as a primary diagnosis if a definitive underlying cause (e.g., diabetes mellitus) has been established and is being treated.
• Always sequence this code after the definitive diagnosis when polydipsia is a manifestation of another condition.
• Ensure documentation clearly distinguishes polydipsia from normal increased fluid intake due to exercise or hot weather.
