About R81

R81 is the ICD-10-CM diagnosis code for glycosuria. It belongs to block R80-R82 (abnormal findings on examination of urine, without diagnosis) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Don't report R81 together with the conditions in its Excludes1 note: renal glycosuria (E74.818).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 637 (Diabetes with MCC, relative weight 1.4129), DRG 638 (Diabetes with CC, relative weight 0.9019) and DRG 639 (Diabetes without CC/MCC, relative weight 0.6376), in MDC 10 (Endocrine, Nutritional and Metabolic Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 791.5 (glycosuria).
