ICD-10-CM R81
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

R81 is a billable ICD-10-CM diagnosis code for glycosuria. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 637 through 639. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established. Coders also document this condition as glucose concentration, dipstick - finding. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Abnormal findings without diagnosis.

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to R81: its own notes plus those printed at block R80-R82 and Chapter 18. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

On R81 itself
From Block R80-R82 Abnormal findings on examination of urine, without diagnosis applies to 25 codes
  • abnormal findings on antenatal screening of mother (O28.-)
  • diagnostic abnormal findings classified elsewhere - see Alphabetical Index
  • specific findings indicating disorder of amino-acid metabolism (E70-E72)
  • specific findings indicating disorder of carbohydrate metabolism (E73-E74)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 18 (R00-R99) Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified applies to 774 codes
  • abnormal findings on antenatal screening of mother (O28.-)
  • certain conditions originating in the perinatal period (P04-P96)
  • signs and symptoms classified in the body system chapters
  • signs and symptoms of breast (N63, N64.5)

Notes

General instructions on how these codes are used.

From Chapter 18 (R00-R99) Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified applies to 774 codes
  • This chapter includes symptoms, signs, abnormal results of clinical or other investigative procedures, and ill-defined conditions regarding which no diagnosis classifiable elsewhere is recorded.
  • Signs and symptoms that point rather definitely to a given diagnosis have been assigned to a category in other chapters of the classification. In general, categories in this chapter include the less well-defined conditions and symptoms that, without the necessary study of the case to establish a final diagnosis, point perhaps equally to two or more diseases or to two or more systems of the body. Practically all categories in the chapter could be designated 'not otherwise specified', 'unknown etiology' or 'transient'. The Alphabetical Index should be consulted to determine which symptoms and signs are to be allocated here and which to other chapters. The residual subcategories, numbered .8, are generally provided for other relevant symptoms that cannot be allocated elsewhere in the classification.
  • The conditions and signs or symptoms included in categories R00-R94 consist of:
  • (a) cases for which no more specific diagnosis can be made even after all the facts bearing on the case have been investigated;
  • (b) signs or symptoms existing at the time of initial encounter that proved to be transient and whose causes could not be determined;
  • (c) provisional diagnosis in a patient who failed to return for further investigation or care;
  • (d) cases referred elsewhere for investigation or treatment before the diagnosis was made;
  • (e) cases in which a more precise diagnosis was not available for any other reason;
  • (f) certain symptoms, for which supplementary information is provided, that represent important problems in medical care in their own right.

Clinical InformationClinical

  • 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).

Patient EducationClinical

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.

Questions About R81Overview

What is the ICD-10 code for glycosuria?

The ICD-10-CM code for glycosuria is R81. It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is R81 (Glycosuria) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report glycosuria on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does R81 group to?

When glycosuria is the principal diagnosis on an inpatient stay, it groups to MS-DRG 638, 639, 637, with relative weights from 0.6375 to 1.4127 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R81 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the glycosuria is established, that condition takes the principal position instead.

Can R81 be reported with E74.818?

Not as a rule. The Excludes1 note on R81 lists "renal glycosuria (E74.818)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
