Hereditary nephropathy, NEC w diffuse crescentic glomrlneph

This code signifies a genetic kidney disorder characterized by inflammation of the kidney's filtering units (glomeruli), specifically with the presence of crescent-shaped lesions. These crescent formations indicate severe glomerular injury and rapidly progressive kidney function decline. It applies to hereditary nephropathies that don't fit into more specific categories.

Use this code when documentation clearly indicates a hereditary form of nephropathy alongside a biopsy-confirmed diagnosis of diffuse crescentic glomerulonephritis. This is appropriate when the underlying genetic cause is known but doesn't have a more specific ICD-10-CM code, or when the hereditary nature is established without a precise genetic identification.

• Ensure documentation explicitly states "hereditary" and "diffuse crescentic glomerulonephritis."
• Do not use if a more specific hereditary nephropathy code (e.g., Alport syndrome) is applicable.
• Consider sequencing this code as a primary diagnosis if it is the main reason for the encounter, or as a secondary diagnosis if it's a comorbidity.
