ICD-10-CM Code For Glycosuria: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group R81 includes codes for the presence of glucose in the urine (glycosuria) detected on urinalysis and related abnormal urinary glucose findings without an established causative diagnosis. These ICD-10-CM diagnosis codes are used to document laboratory-detected glycosuria and related abnormal urine glucose findings, capturing information about metabolic status or renal glucose handling that may require further evaluation. Accurate coding within the ICD-10-CM R81 group supports complete clinical documentation and appropriate reimbursement.

ICD-10-CM R81: Glycosuria Overview

The ICD-10-CM R81 diagnosis group represents the finding of glucose in the urine without a definitive underlying diagnosis recorded. These codes target urinary system laboratory findings associated with metabolic or renal conditions and signal abnormal glucose handling or filtered load. Accurate coding matters for appropriate clinical documentation and may affect reimbursement when laboratory findings influence medical decision-making.

When to Use

Use a code from this group when urine testing documents glucose in the urine and no definitive diagnosis explaining the finding is recorded in the encounter. These codes apply to cases where the abnormal urine glucose result is the primary documented finding being reported for that visit.

Typical Clinical Scenarios

An adult presents to urgent care with polyuria and polydipsia after several days of illness; a point-of-care urine dipstick and lab urinalysis reveal new-onset glucose in the urine without prior diabetes documentation. The clinician documents the abnormal urine finding while arranging fasting blood glucose and HbA1c follow-up to evaluate for possible hyperglycemia. Typical codes: R81
A pregnant patient at a routine prenatal visit has a urine screen that shows glycosuria but her blood glucose screening earlier in pregnancy was normal; the obstetric nurse documents the urinary glucose as an abnormal urine finding and schedules additional glucose tolerance testing. Typical codes: R81
An inpatient with chronic kidney disease is admitted for evaluation of worsening edema; urinalysis performed for workup shows glycosuria despite measured normoglycemia, noted as an abnormal urine finding that may reflect proximal tubular dysfunction or medication effect. Typical codes: R81
