Chronic neph syndrome w focal and seg glomerular lesions

This code signifies a persistent inflammatory condition of the kidney's filtering units (glomeruli) characterized by specific microscopic changes where only parts of some glomeruli are affected. It typically presents with proteinuria, hematuria, and often progressive renal dysfunction. This chronic form indicates ongoing disease rather than an acute episode.

Apply this code when documentation confirms a diagnosis of chronic nephritic syndrome and a renal biopsy report or pathology findings specifically identify focal and segmental glomerular lesions. This diagnosis is often made after persistent signs of glomerular disease and histological confirmation.

• Ensure the documentation clearly specifies "chronic" and not "acute" or "rapidly progressive" nephritic syndrome.
• Look for explicit mention of "focal and segmental glomerulosclerosis" or similar terminology in pathology reports.
• Do not use this code if the biopsy indicates diffuse or other specific types of glomerular lesions; select the appropriate N03 subcategory.
