Nephrotic syndrome with diffuse membranous glomrlneph, unsp

This code signifies a kidney disorder characterized by significant protein loss in the urine (nephrotic syndrome) occurring concurrently with diffuse membranous glomerulonephritis, a specific type of kidney inflammation where immune complexes deposit along the glomerular basement membrane. The "unspecified" aspect indicates that the underlying cause or stage of the membranous glomerulonephritis is not documented.

Apply this code when documentation clearly states a diagnosis of nephrotic syndrome and diffuse membranous glomerulonephritis, but the physician has not specified the etiology (e.g., primary, secondary to lupus, hepatitis B). This code is appropriate when the provider has not indicated whether the condition is in remission or active.

• Avoid using this code if the underlying cause of the membranous glomerulonephritis is known; instead, select a more specific code from the N04.2 subcategory.
• Ensure documentation explicitly links nephrotic syndrome with diffuse membranous glomerulonephritis; do not assume the connection.
• If the laterality of the kidney involvement is specified (e.g., left, right, bilateral), this code does not allow for that level of detail, as it is a systemic condition.
