AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2020 Issue 4; New/Revised ICD-10-CM Codes
C3 Glomerulopathy
Changes have been made at categories N00 to N07 to identify glomerular diseases to align with clinical consensus of complement component 3 (C3) glomerulopathy (C3G) subtypes critical for identifying appropriate disease etiology, patient segmentation, and therapeutic selection. The new codes identify C3 glomerulonephritis (C3GN) with conditions classified to categories N00-N07 as noted below:N00.A Acute nephritic syndrome with C3 glomerulonephritis N01.A Rapidly progressive nephritic syndrome with C3 glomerulonephritis N02.A Recurrent and persistent hematuria with C3 glomerulonephritis N03.A Chronic nephritic syndrome with C3 glomerulonephritis N04.A Nephrotic syndrome with C3 glomerulonephritis N05.A Unspecified nephritic syndrome with...

Article Overview
This article explains recent ICD-10-CM updates tied to complement component 3 glomerulopathy and its recognized subtypes. It is intended for coding and clinical audiences who need to understand the scope of the classification change, the affected nephrology categories, and the general reason the update matters for diagnosis grouping and disease identification.
Why This Topic Matters
C3 glomerulopathy is a specialized renal diagnosis area where classification changes affect how glomerular disease is captured in coded data. The article helps readers identify which diagnosis categories were updated and understand the broader clinical context behind the coding revision.
