R31.29
ICD-10-CMThis code signifies the presence of microscopic blood in the urine, detected through laboratory analysis, where the specific cause of the hematuria has not been identified or is not classifiable to a more specific code. It indicates an abnormal finding on urinalysis that warrants further investigation.
Use this code when documentation confirms microscopic hematuria, and the provider has not yet determined the underlying etiology, or the cause is not specified as benign essential, asymptomatic, or recurrent. This code is appropriate when the urinalysis report indicates red blood cells in the urine, and no other definitive diagnosis for the hematuria is documented.
