J32.4
ICD-10-CMThis code signifies a persistent, long-term inflammation affecting all paranasal sinuses (frontal, ethmoid, sphenoid, and maxillary). It is characterized by chronic symptoms such as facial pain, pressure, nasal obstruction, and discharge, lasting typically 12 weeks or longer. The condition involves widespread mucosal thickening and often polyps within the entire sinus system.
Apply this code when documentation clearly indicates chronic inflammation involving all four major sinus groups. This diagnosis is supported by imaging studies (e.g., CT scan showing diffuse opacification or mucosal thickening across all sinuses) and clinical findings consistent with chronic sinusitis symptoms affecting the entire sinus cavity.
