The ICD code M315 is used to code Giant-cell arteritis
Giant-cell arteritis (GCA or temporal arteritis or cranial arteritis) or Horton disease is an inflammatory disease of blood vessels most commonly involving large and medium arteries of the head, predominantly the branches of the external carotid artery. The most serious complication is occlusion of the ophthalmic artery, which is a branch of the internal carotid. It can create a medical emergency which can cause irreversible ischemia and blindness if not treated promptly. GCA is treated with glucocorticoids (steroids), which reduce the inflammation and prevent occlusion. No other drugs are effective or contribute to the effect of glucocorticoids.
