Unsp nephritic syndrome w diffuse mesangiocap glomrlneph

This code represents a form of nephritic syndrome characterized by inflammation of the kidney's glomeruli, specifically with a diffuse mesangiocapillary pattern identified on renal biopsy. The "unspecified" nature indicates that further details regarding the specific cause or chronicity of the nephritic syndrome are not documented.

Use this code when documentation explicitly states "unspecified nephritic syndrome with diffuse mesangiocapillary glomerulonephritis" following a renal biopsy. It is appropriate when the physician has not specified the underlying etiology of the nephritic syndrome, but the histological findings are clear.

• Do not use this code if the documentation specifies C3 glomerulonephritis or C3 glomerulopathy, as these have separate, more specific codes.
• Ensure the pathology report clearly identifies "diffuse mesangiocapillary glomerulonephritis" in conjunction with a diagnosis of unspecified nephritic syndrome.
• Review the entire medical record for any further specificity regarding the cause of the nephritic syndrome, which might lead to a more precise code.
