Acute nephritic syndrome w diffuse membranous glomrlneph

This code signifies a sudden onset of kidney inflammation characterized by widespread thickening of the glomerular basement membrane. It typically presents with hematuria, proteinuria, hypertension, and renal impairment due to immune complex deposition in the glomeruli.

Apply this code when documentation explicitly states acute nephritic syndrome and specifies diffuse membranous glomerulonephritis as the underlying pathology. This diagnosis is often confirmed by renal biopsy findings.

• Ensure documentation clearly distinguishes acute from chronic conditions, as membranous glomerulonephritis can also be chronic.
• Look for specific mention of "diffuse" to differentiate from other forms of membranous nephropathy.
• Code any associated complications, such as acute kidney injury, separately.
