Glycosuria
In Abnormal findings on examination of urine, without diagnosis (R80-R82), chapter 18: Symptoms, Signs and Abnormal Clinical and Laboratory Findings
- R81 is billable and valid on claims for FY 2027. If the record has more detail, check the other codes under R80-R82 below.
- As a secondary diagnosis it is not a CC or MCC, so it doesn't raise the MS-DRG payment.
- Doesn't count toward a Medicare Advantage risk score (no HCC in V28).
- AHRQ's Chronic Condition Indicator classes it as not chronic (an acute or short-term condition).
Also indexed as: Abnormal, urine, glucose; Findings, glycosuria; Findings, urine, glucose; Findings, urine, sugar; Glycosuria; Sugar, in urine

R81 MS-DRGs
As the principal diagnosis, R81 groups to MS-DRG 637, 638, or 639 (v44.0). Which one applies depends on procedures performed, secondary diagnoses (CC/MCC), and the patient's age and discharge status.

About the condition

Urine and Urination
Your kidneys make urine by filtering wastes and extra water from your blood. The waste is called urea. Your blood carries it to the kidneys. From the kidneys, urine travels down two thin tubes called ureters to the bladder. The bladder stores urine until you are ready to urinate. It swells into a round shape when it is full and gets smaller when empty. If your urinary system is healthy, your bladder can hold up to 16 ounces (2 cups) of urine comfortably for 2 to 5 hours.
