R80: ICD10 Code for Proteinuria
R80 is the ICD10 code used for documenting Proteinuria based on abnormal urine test results.

R80 refers to Proteinuria, highlighting unusual findings in urine samples such as elevated protein levels, sugar presence, or other chemical and microscopic abnormalities.
Symptoms
- Protein detected in urine – R80
- Glucose detected in urine – R81
- Other unusual findings like ketones, blood, or crystals – R82
Diagnosis
Urinalysis, dipstick tests, microscopic urine analysis, and sometimes 24-hour urine collection help detect and confirm the presence of proteinuria, glycosuria, or other urine abnormalities requiring further clinical investigation.
ICD10 Code Usage
ICD10 code R80 is used to classify abnormal urine findings during initial evaluations, clinical screenings, or in patients undergoing follow-up for chronic conditions such as diabetes, kidney disease, or metabolic disorders.

Q4: How are other abnormal urine findings managed?
A: Further lab work, imaging, and specialist consultation (like nephrology) may be warranted based on the findings.
Q5: Why document abnormal urine findings separately?
A: Early detection and categorization of urine abnormalities guide targeted diagnostic testing and timely treatment interventions.
