R84.6

Abnormal cytological findings in specimens from respiratory organs and thorax

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

Code Description

ICD-10 R84.6 is a billable code used to indicate a diagnosis of abnormal cytological findings in specimens from respiratory organs and thorax.

Key Diagnostic Point:

R84.6 is used to classify abnormal cytological findings in specimens obtained from respiratory organs and the thorax. This code encompasses a variety of abnormal results from cytological examinations, which may include atypical cells, neoplastic changes, or other cellular abnormalities detected in samples such as sputum, bronchoalveolar lavage, or pleural fluid. These findings can indicate a range of conditions, from benign processes to malignancies, and may necessitate further diagnostic evaluation or intervention. The clinical context is crucial, as abnormal cytological findings can be associated with infections, inflammatory diseases, or neoplastic processes, and the interpretation of these findings often requires correlation with clinical symptoms and imaging studies. Accurate coding is essential for appropriate patient management and reimbursement.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in cytological findings interpretation
  • Need for correlation with clinical history and imaging
  • Potential overlap with other respiratory conditions
  • Documentation of the specific type of abnormality

Audit Risk Factors

  • Inadequate documentation of cytological findings
  • Failure to correlate findings with clinical symptoms
  • Misinterpretation of benign vs. malignant findings
  • Inconsistent coding practices among providers

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of abnormal findings, improving the granularity of data for respiratory conditions and enhancing the ability to track and manage patient outcomes.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of abnormal findings, improving the granularity of data for respiratory conditions and enhancing the ability to track and manage patient outcomes.

Reimbursement & Billing Impact
