ICD10 code of Granulomatosis with Polyangiitis (GPA) and ICD9 code

Granulomatosis with Polyangiitis (GPA), also known as Wegener's granulomatosis, is a rare autoimmune disorder characterized by inflammation of blood vessels, leading to granulomatous lesions in various organs. In the ICD-10 coding system, the code for GPA is M31.3. This code falls under the category of "Other necrotizing vasculopathies," which includes several related conditions involving inflammation and damage to blood vessels.

In the previous ICD-9 coding system, Granulomatosis with Polyangiitis was classified under multiple codes depending on the affected organ systems. The codes included 446.4 for Wegener's granulomatosis involving respiratory system, 446.21 for Wegener's granulomatosis involving kidneys, and 446.29 for Wegener's granulomatosis involving other organs. These codes are part of the "Nonspecific lymphadenitis" section in ICD-9.

It's important to note that the transition from ICD-9 to ICD-10 occurred in October 2015, so healthcare providers now primarily use the ICD-10 coding system. This transition allowed for more specific and detailed coding, enabling better tracking of diseases and improved patient care.

If you or someone you know is dealing with Granulomatosis with Polyangiitis, it is essential to consult a healthcare professional for accurate diagnosis, treatment, and ongoing management.
