Nephritis and nephropathy, not specified as acute or chronic, with lesion of proliferative glomerulonephritis

This code signifies kidney inflammation and disease that is not specified as either sudden onset or long-standing, and is specifically characterized by a proliferative form of glomerulonephritis. This indicates an increase in the number of cells within the glomeruli, the filtering units of the kidney.

This code is appropriate when documentation clearly states "nephritis and nephropathy" with a confirmed lesion of "proliferative glomerulonephritis," but the physician has not specified the acuity (acute or chronic). It's used when the diagnostic workup confirms the specific glomerular lesion without clarifying the temporal aspect of the kidney disease.

• Ensure the documentation explicitly mentions "proliferative glomerulonephritis" as the lesion type.
• Avoid using this code if the physician specifies "acute" or "chronic" glomerulonephritis; use the more specific codes in those instances.
• Look for supporting pathology reports or biopsy results that confirm the proliferative nature of the glomerular lesion.
