The ICD code M313 is used to code Granulomatosis with polyangiitis

Granulomatosis with polyangiitis (GPA), formerly referred to as Wegener's granulomatosis (WG), is a systemic disorder that involves both granulomatosis and polyangiitis. It is a form of vasculitis (inflammation of blood vessels) that affects small- and medium-size vessels in many organs. Damage to the lungs and kidneys can be fatal. It requires long-term immunosuppression. The condition was originally named for Friedrich Wegener, who described the disease in 1936. As a response to Wegener's association with the German Nazi party, professional bodies and journals have replaced his name with a descriptive name. However, the older name is still often seen.
