Recurrent and perst hematur w diffuse crescentic glomrlneph

This diagnosis code signifies a chronic kidney condition characterized by the persistent presence of blood in the urine (hematuria) and inflammation of the kidney's filtering units (glomeruli). The specific type of inflammation, diffuse crescentic glomerulonephritis, indicates severe damage to the glomeruli with crescent-shaped scar tissue formation, often leading to rapid kidney function decline.

This code is appropriate when documentation confirms recurrent or ongoing hematuria in conjunction with a biopsy-proven diagnosis of diffuse crescentic glomerulonephritis. It is used for patients experiencing persistent microscopic or macroscopic hematuria due to this specific and aggressive form of glomerulonephritis.

• Ensure documentation explicitly states "diffuse crescentic glomerulonephritis" and "recurrent" or "persistent" hematuria.
• Do not use this code for isolated hematuria without a confirmed glomerular disease or for other types of glomerulonephritis.
• Consider sequencing this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if another condition is the primary focus of treatment.
