Glycosuria (R81)
The ICD-10 code R81 is used to document the presence of **glycosuria**, which means glucose is found in the urine. This code captures abnormal urine glucose findings without specifying an underlying diagnosis.
R81 covers conditions commonly referred to by terms such as "urine glucose test = trace," "+," "++," or higher levels indicated on dipstick testing. These synonyms reflect varying glucose concentrations detected during urine testing and help clarify that the code applies specifically to glucose detected in urine, regardless of the cause. Medical coders use this code when glucose is present in the urine as an abnormal finding without attributing it to a diagnosed condition like diabetes. It is a key code for reporting urine glucose test results that show positive findings but do not yet confirm or diagnose any particular disorder.
Instructional Notations
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Glycosuria
The appearance of an abnormally large amount of GLUCOSE in the urine, such as more than 500 mg/day in adults. It can be due to HYPERGLYCEMIA or genetic defects in renal reabsorption (RENAL GLYCOSURIA).
Glycosuria, Renal
An autosomal inherited disorder due to defective reabsorption of GLUCOSE by the PROXIMAL RENAL TUBULES. The urinary loss of glucose can reach beyond 50 g/day. It is attributed to the mutations in the SODIUM-GLUCOSE TRANSPORTER 2 encoded by the SLC5A2 gene.
