Polyp of nasal cavity

This code identifies the presence of a benign, non-cancerous growth originating from the lining of the nasal cavity. These polyps are typically soft, painless, and often appear as teardrop-shaped masses. They can obstruct airflow and lead to symptoms such as nasal congestion, reduced sense of smell, and postnasal drip.

Use this code when documentation clearly indicates a diagnosis of a polyp located specifically within the nasal cavity. This diagnosis is often made via anterior rhinoscopy or nasal endoscopy. Supporting documentation should specify the location as the nasal cavity, differentiating it from polyps in paranasal sinuses.

• Differentiate from polyps originating in the paranasal sinuses (e.g., J33.1 for polyp of ethmoidal sinus).
• Do not use for inflammatory polyps of the middle ear (H74.4-).
• If laterality is specified in the documentation (e.g., left or right nasal cavity), this code does not allow for laterality assignment.
