R94.128

Abnormal results of other function studies of ear and other special senses

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

Code Description

ICD-10 R94.128 is a billable code used to indicate a diagnosis of abnormal results of other function studies of ear and other special senses.

Key Diagnostic Point:

R94.128 is used to classify abnormal results from function studies related to the ear and other special senses that do not fall under more specific categories. This code encompasses a variety of symptoms and signs that may arise from dysfunction in sensory modalities, including hearing, vision, taste, and balance. Common clinical findings may include abnormal audiometry results, vestibular function tests, or visual field assessments. These abnormalities can indicate underlying conditions such as sensorineural hearing loss, vestibular disorders, or optic nerve issues. The clinical context often involves patients presenting with symptoms like dizziness, tinnitus, or visual disturbances, prompting further investigation through specialized function studies. Accurate coding requires a thorough understanding of the specific tests performed and the clinical implications of the results, as well as the documentation of any associated symptoms or findings.

  • Need for precise documentation of abnormal findings
  • Differentiation from other similar codes
  • Potential overlap with other diagnoses

Audit Risk Factors

  • Inadequate documentation of test results
  • Failure to specify the type of function study performed
  • Misclassification of symptoms leading to incorrect coding
  • Lack of correlation between clinical findings and test results

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specificity in coding, which can improve the accuracy of diagnoses related to sensory function studies. R94.128 provides a means to capture abnormal findings that may not have been adequately classified in ICD-9.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specificity in coding, which can improve the accuracy of diagnoses related to sensory function studies. R94.128 provides a means to capture abnormal findings that may not have been adequately classified in ICD-9.

Reimbursement & Billing Impact
