Unspecified nephritic syndrome with C3 glomerulonephritis

📋Clinical Description

This code signifies a form of nephritic syndrome where the specific cause is not fully identified, but a C3 glomerulonephritis is confirmed. It indicates an inflammatory kidney disorder characterized by hematuria, proteinuria, and often hypertension and renal insufficiency, with immune complex deposits primarily composed of complement component 3.

🎯When to Use

Apply this code when documentation specifies "unspecified nephritic syndrome" and explicitly mentions "C3 glomerulonephritis" without further detail regarding the specific type of C3 glomerulopathy. This is appropriate when the provider has confirmed C3 glomerulonephritis but has not specified if it is dense deposit disease or another variant.

💡Coding Tips

Do not use this code if the documentation specifies "dense deposit disease" alongside C3 glomerulopathy; refer to the Excludes1 note.
Ensure the medical record clearly states "C3 glomerulonephritis" to support the use of this specific code.
Consider additional codes for any associated manifestations or complications, such as chronic kidney disease stage.
