AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2023 Issue 4; New/Revised ICD-10-CM Codes
Chronic Lung Allograft Dysfunction
New codes have been created to identify restrictive, chronic and other lung allograft dysfunction as follows: • J4A.0, Restrictive allograft syndrome • J4A.8, Other chronic lung allograft dysfunction • J4A.9, Chronic lung allograft dysfunction, unspecified CLAD, also known as chronic rejection, is a syndrome of progressive lung function decline where the immune system attacks the airways of the lungs. Two subtypes of CLAD have been defined [bronchiolitis obliterans syndrome (BOS) and restrictive allograft syndrome (RAS) or restrictive CLAD (rCLAD)].Restrictive allograft syndrome (RAS) is a new type of chronic lung allograft dysfunction that can develop after...
