Persistent proteinuria, unspecified

This code signifies the ongoing presence of protein in the urine, without further specification of the type or cause of the proteinuria. It indicates a chronic or recurrent finding of elevated urinary protein levels that has not been definitively characterized.

Use this code when documentation confirms persistent proteinuria but lacks details regarding its specific nature (e.g., orthostatic, Bence Jones, microalbuminuria) or underlying etiology. This is appropriate for initial findings of persistent proteinuria before a more specific diagnosis is established.

• Do not use if the type of proteinuria is specified (e.g., orthostatic, Bence Jones); use a more specific code from the R80 category.
• Always seek clarification from the provider if the documentation suggests a specific cause or type of proteinuria but does not explicitly state it.
• This code is often a temporary assignment while further diagnostic workup is underway to identify the underlying cause of the persistent proteinuria.
