R82.89

Other abnormal findings on cytological and histological examination of urine

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

Code Description

ICD-10 R82.89 is a billable code used to indicate a diagnosis of other abnormal findings on cytological and histological examination of urine.

Key Diagnostic Point:

R82.89 is used to classify abnormal findings identified during cytological and histological examinations of urine that do not fall under more specific codes. These findings may include atypical cells, inflammatory cells, or other cellular abnormalities that suggest underlying pathology. Such abnormalities can indicate a range of conditions, from benign processes to malignancies. The examination of urine cytology is often performed to evaluate for urinary tract infections, bladder cancer, or other urological disorders. The interpretation of these findings requires careful correlation with clinical symptoms, patient history, and additional diagnostic tests to establish a definitive diagnosis and appropriate treatment plan.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of potential underlying conditions represented by abnormal findings.
  • Need for correlation with clinical symptoms and history.
  • Potential overlap with other codes for urinary findings.
  • Variability in documentation practices among providers.

Audit Risk Factors

  • Inadequate documentation of clinical findings.
  • Failure to link abnormal findings to specific diagnoses.
  • Misinterpretation of cytological results leading to incorrect coding.
  • Lack of follow-up documentation on abnormal findings.

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of abnormal findings, improving the granularity of data collection and analysis. R82.89 provides a means to capture findings that do not fit neatly into other categories, enhancing the understanding of urinary abnormalities in clinical practice.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of abnormal findings, improving the granularity of data collection and analysis. R82.89 provides a means to capture findings that do not fit neatly into other categories, enhancing the understanding of urinary abnormalities in clinical practice.
