| ICD-10 from 2011 - 2016

M30.1 is a billable ICD code used to specify a diagnosis of polyarteritis with lung involvement [Churg-Strauss]. A 'billable code' is detailed enough to be used to specify a medical diagnosis.


The ICD code M301 is used to code Churg-Strauss syndrome

Churg–Strauss syndrome (CSS, also known as eosinophilic granulomatosis with polyangiitis [EGPA] or allergic granulomatosis) is an autoimmune condition that causes inflammation of small and medium-sized blood vessels (vasculitis) in persons with a history of airway allergic hypersensitivity (atopy). It usually manifests in three stages. The early (prodromal) stage is marked by airway inflammation; almost all patients experience asthma and/or allergic rhinitis. The second stage is characterized by abnormally high numbers of eosinophils (hypereosinophilia), which causes tissue damage, most commonly to the lungs and the digestive tract. The third stage consists of vasculitis, which can eventually lead to cell death and can be life-threatening.
