Postural proteinuria

This code represents a benign condition characterized by the presence of protein in the urine (proteinuria) that occurs only when an individual is in an upright or standing position, resolving when recumbent. It is typically asymptomatic and not indicative of underlying kidney disease.

Use this code when documentation clearly indicates proteinuria that is position-dependent, often discovered incidentally during routine urinalysis. This diagnosis is typically made after ruling out other causes of proteinuria through a split urine collection (daytime vs. nighttime samples).

• Ensure documentation specifies "postural" or "orthostatic" proteinuria to differentiate from other forms.
• Do not use this code if there is evidence of persistent proteinuria or other signs of renal dysfunction.
• This is a diagnosis of exclusion; ensure other causes of proteinuria have been investigated and ruled out.
