Acute nephritic syndrome w diffuse crescentic glomrlneph

This code signifies a severe and rapidly progressive form of acute nephritic syndrome characterized by widespread crescent formation in the glomeruli. It indicates significant inflammation and damage to the kidney's filtering units, often leading to rapid decline in renal function.

Apply this code when documentation explicitly states acute nephritic syndrome with diffuse crescentic glomerulonephritis. This typically occurs in cases of rapidly progressive glomerulonephritis (RPGN) where biopsy confirms the presence of crescents in more than 50% of glomeruli.

• Ensure documentation specifies "diffuse crescentic" to differentiate from focal or segmental crescentic forms.
• Do not confuse with other forms of acute nephritic syndrome without documented crescent formation.
• Consider sequencing this code as the primary diagnosis when it is the main reason for the encounter and treatment.
