Acute neph syndrome w diffuse endocaplry prolif glomrlneph

This code signifies a rapid onset of kidney inflammation characterized by hematuria, proteinuria, hypertension, and often oliguria, specifically due to an overgrowth of cells within the glomerular capillaries. It represents a severe form of acute glomerulonephritis where the endocapillary proliferation is diffuse.

Assign this code when documentation explicitly states acute nephritic syndrome with a biopsy-confirmed diagnosis of diffuse endocapillary proliferative glomerulonephritis. This typically follows an infectious process, such as post-streptococcal glomerulonephritis. Supporting documentation includes pathology reports detailing the specific glomerular changes.

• Ensure the documentation specifies "diffuse endocapillary proliferative" and not another histological type of glomerulonephritis.
• Do not use this code for chronic or rapidly progressive glomerulonephritis.
• Code any underlying infectious etiology, such as streptococcal infection, as an additional diagnosis.
