Chronic neph syndrome w diffuse endocaplry prolif glomrlneph

This code describes a long-standing inflammation of the kidney's filtering units (glomeruli) characterized by the overgrowth of cells within the capillaries of the glomerulus, affecting them throughout. This chronic condition leads to impaired kidney function and can manifest with symptoms like proteinuria, hematuria, and hypertension.

Use this code when documentation explicitly states a diagnosis of chronic nephritic syndrome with a biopsy-confirmed finding of diffuse endocapillary proliferative glomerulonephritis. This typically applies to patients with persistent signs of glomerular disease and a definitive histological diagnosis.

• Ensure the documentation specifies "chronic" to differentiate from acute or rapidly progressive forms.
• Verify that the specific type of glomerulonephritis, "diffuse endocapillary proliferative," is clearly stated in pathology reports.
• Do not use this code for other forms of glomerulonephritis (e.g., membranous, focal segmental) or for acute presentations.
