CA0C Cyst or mucocele of nose or nasal sinus

International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2024-01


A condition which refers to diseases of the nose and nasal sinus that cause a cyst or mucocele. A mucocele is any dilatation (typically pathologic) with accumulation of mucus. Mucoceles are benign, epithelium-lined cysts filled with mucus, which can form in the paranasal sinuses. These structures may cause symptoms if sufficiently large or if exerting pressure on surrounding anatomic structures. Symptomatic mucoceles typically require surgical intervention. Mucoceles should be differentiated from sinus retention cysts. Unlike mucoceles, sinus retention cysts do not result in expansion and thinning of the bony sinus walls.
