Code Description

ICD-10 R23.2 is a billable code used to indicate a diagnosis of flushing.

Key Diagnostic Point:

Flushing is characterized by a sudden reddening of the skin, typically on the face, neck, and upper chest, often accompanied by a sensation of warmth. This symptom can arise from various physiological and pathological processes, including vasodilation, increased blood flow, or hormonal changes. Common causes of flushing include emotional responses (e.g., embarrassment, anxiety), physical exertion, exposure to heat, certain medications (e.g., niacin, vasodilators), and medical conditions such as menopause, carcinoid syndrome, or hyperthyroidism. The flushing may be transient or persistent, and its clinical significance can vary widely depending on the underlying cause. Accurate diagnosis often requires a thorough patient history, physical examination, and, if necessary, laboratory tests to rule out systemic conditions. Flushing can also be a side effect of certain medications or a symptom of an allergic reaction, necessitating careful evaluation to determine the appropriate management and treatment.
