J33.9
ICD-10-CMThis code signifies the presence of a non-cancerous growth originating from the lining of the nasal passages or paranasal sinuses, without further specification of its type or location. These benign lesions can obstruct airflow, lead to chronic rhinosinusitis, and impair the sense of smell.
Apply this code when documentation clearly indicates a nasal polyp but lacks specific details regarding its etiology (e.g., allergic, inflammatory) or precise anatomical site within the nasal cavity or sinuses. This is appropriate for initial diagnoses or when further diagnostic workup is pending.
