4A44.2 Giant cell arteritis International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2024-01 Arteritis, often granulomatous, usually affecting the aorta and/or its major branches, with a predilection for the branches of the carotid artery. Often involves the temporal artery. Onset usually in patients older than 50 and often associated with polymyalgia rheumatica.
