Rapid progr neph synd w diffus endocaplry prolif glomrlneph

This code represents a severe and rapidly worsening form of kidney inflammation characterized by the rapid decline of renal function, often leading to end-stage renal disease within weeks or months. Histologically, it involves widespread proliferation of cells within the glomerular capillaries. This condition is a subtype of rapidly progressive glomerulonephritis (RPGN) with a specific pathological finding.

Use this code when documentation clearly indicates rapidly progressive nephritic syndrome and a kidney biopsy confirms diffuse endocapillary proliferative glomerulonephritis. This diagnosis is typically made in patients presenting with acute kidney injury, hematuria, proteinuria, and often hypertension, with a rapid decline in GFR.

• Ensure documentation specifies "diffuse endocapillary proliferative" to differentiate from other RPGN subtypes.
• Do not confuse with other forms of glomerulonephritis that are not rapidly progressive or do not have the specific endocapillary proliferation.
• Consider sequencing this code as the primary diagnosis when it is the main reason for the encounter and treatment.
