R82.91

Other chromoabnormalities of urine

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R82.91 is a billable code used to indicate a diagnosis of other chromoabnormalities of urine.

Key Diagnostic Point:

R82.91 is used to classify abnormal findings in urine that are not specifically categorized elsewhere in the ICD-10 coding system. These abnormalities may include unusual colors, turbidity, or the presence of substances such as crystals, casts, or other elements that indicate a deviation from normal urine composition. Such findings can be indicative of various underlying conditions, including metabolic disorders, renal dysfunction, or urinary tract infections. The clinical significance of these abnormalities often requires further investigation to determine the underlying cause, which may involve additional laboratory tests, imaging studies, or referrals to specialists. Accurate documentation of the clinical context, including symptoms and any relevant patient history, is essential for appropriate coding and subsequent treatment planning.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation of urinary abnormalities
  • Need for comprehensive patient history to determine underlying causes
  • Potential overlap with other urinary codes
  • Documentation requirements for specificity

Audit Risk Factors

  • Insufficient documentation of clinical findings
  • Failure to link symptoms with the diagnosis
  • Inconsistent use of terminology in lab results
  • Lack of follow-up documentation for abnormal findings
