Code Description

ICD-10 N06.0 is a billable code used to indicate a diagnosis of isolated proteinuria with minor glomerular abnormality.

Key Diagnostic Point:

Isolated proteinuria with minor glomerular abnormality refers to the presence of protein in the urine without significant clinical symptoms or major structural abnormalities in the kidneys. This condition is often identified during routine urinalysis and may indicate underlying glomerular dysfunction. The proteinuria is typically low to moderate in quantity and is not associated with other renal impairments such as hypertension or significant renal insufficiency. Minor glomerular abnormalities may include changes in glomerular morphology that are not severe enough to warrant a diagnosis of a specific glomerular disease. Isolated proteinuria can be a transient condition, often influenced by factors such as exercise, dehydration, or fever. In some cases, hereditary nephropathies may predispose individuals to isolated proteinuria, necessitating further genetic evaluation. The management of this condition often involves monitoring renal function and protein levels, as well as addressing any underlying causes.
