2025 ICD-10-CM code R80.8
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Abnormal findings on examination of urine, without diagnosis - Other proteinuria Chapter 19: Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified Feed
This code signifies the presence of protein in the urine that doesn't fit into other, more specific proteinuria categories.
Medical necessity is established by the presence of proteinuria and the need to investigate the underlying cause to determine if treatment is required or if ongoing monitoring is necessary. This could be triggered by abnormal lab findings and subsequent clinical assessment.
The clinical responsibility involves identifying and characterizing the proteinuria through urinalysis and other relevant tests, and determining the underlying cause through further investigation such as renal function tests and imaging (ultrasound, CT scans).This may include referral to a nephrologist or other specialist depending on the findings.

- R80-R82: Abnormal findings on examination of urine, without diagnosis
In simple words: This code means that a test found more protein than normal in your urine, but doctors don't yet know why.
R80.8, Other proteinuria, is an ICD-10-CM code used to classify the presence of an abnormal amount of protein in the urine when the specific type or cause of the proteinuria cannot be determined or does not fit into more specific categories (R80.0-R80.3, R80.9).It indicates a general finding of proteinuria requiring further investigation to determine the underlying etiology.This code is applied when all other possibilities have been ruled out and the proteinuria remains unexplained. The diagnosis is considered "other" due to a lack of definitive information as to the specific type of protein present in the urine or the reason for its excretion.
Example 1: A patient presents with routine urinalysis showing elevated protein levels, but further investigation, including imaging and blood work, reveals no obvious cause such as kidney disease or infection.R80.8 would be used in this scenario., A patient with a history of unexplained proteinuria undergoes extensive workup, which does not identify a specific cause despite multiple tests and specialist referrals.R80.8 is appropriate in this instance., A patient with a known condition like a urinary tract infection or other illness displays some unexpected proteinuria. While the primary diagnosis will be the known condition, R80.8 might be used as a secondary code if the proteinuria is unexplained in relation to the primary diagnosis.
Detailed urinalysis report indicating the presence and quantity of protein.Results of any further investigations to determine the cause (e.g., kidney function tests, imaging studies, specialist consultations).Physician's notes detailing the clinical presentation, findings, and reasoning for coding.
** This code should only be used when other more specific codes for proteinuria are not applicable after a complete investigation.The use of this code should trigger further investigation to uncover the underlying cause of the proteinuria. The absence of a clear cause should be documented thoroughly.
