Isolated proteinuria w diffuse endocaplry prolif glomrlneph

This code signifies a kidney disorder characterized by the presence of excess protein in the urine without other significant urinary abnormalities, specifically caused by inflammation and proliferation of cells within the glomeruli's capillaries. This form of glomerulonephritis is identified by a distinct pattern of cellular growth affecting the inner lining of the glomerular capillaries.

Apply this code when documentation specifies isolated proteinuria and a biopsy-confirmed diagnosis of diffuse endocapillary proliferative glomerulonephritis. This is often seen in cases of post-infectious glomerulonephritis or certain autoimmune conditions affecting the kidneys. Supporting documentation must clearly state both the isolated proteinuria and the specific histological findings.

• Ensure documentation explicitly states "isolated proteinuria" and "diffuse endocapillary proliferative glomerulonephritis."
• Do not use this code if other significant urinary abnormalities (e.g., hematuria, casts) are present, even with endocapillary proliferation.
• Review for any underlying systemic diseases that may be causing the glomerulonephritis; these should be coded additionally as primary diagnoses if applicable.
