AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2020 Quarter 4; New/Revised ICD-10-CM Codes
Progressive Fibrotic Interstitial Lung Disease
Code J84.17 , Other interstitial pulmonary diseases with fibrosis in diseases classified elsewhere, has been expanded with new codes to identify interstitial lung disease (ILD) with progressive fibrotic phenotype in diseases classified elsewhere. The new codes are as follows. J84.170 Interstitial lung disease with progressive fibrotic phenotype in diseases classified elsewhere J84.178 Other interstitial pulmonary diseases with fibrosis in diseases classified elsewhere ILD encompasses a large group of pulmonary disorders. Although the ILDs are heterogeneous in etiology, pathophysiology and clinical course, the major abnormality in ILDs is disruption of the distal lung parenchyma. While the pathogenesis remains...

Article Overview
This article covers a coding update in ICD-10-CM alongside a high-level overview of interstitial lung disease and the progressive fibrosing phenotype. It is relevant to coding professionals, clinical documentation stakeholders, and anyone tracking pulmonary diagnosis coding changes because it explains the scope of the update, the condition category involved, and the general purpose of the new codes.
Why This Topic Matters
The update matters because it affects how certain interstitial lung disease diagnoses are represented in ICD-10-CM and supports more specific data capture for a clinically important disease subgroup. The article also places the coding change in the context of progressive fibrosing ILD, which is important for understanding documentation and analytics needs.
