R94.110

Abnormal electro-oculogram [EOG]

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

Code Description

ICD-10 R94.110 is a billable code used to indicate a diagnosis of abnormal electro-oculogram [eog].

Key Diagnostic Point:

An abnormal electro-oculogram (EOG) indicates atypical electrical activity in the retina and surrounding tissues, which can be indicative of various ocular and neurological conditions. The EOG measures the electrical potential difference between the front and back of the eye, primarily assessing the function of the retinal pigment epithelium and the integrity of the visual pathway. Abnormal findings may present as reduced amplitude or altered waveform patterns, which can suggest conditions such as retinitis pigmentosa, macular degeneration, or other retinal disorders. Additionally, abnormal EOG results may be associated with neurological disorders affecting visual processing. Clinicians often utilize EOG in conjunction with other diagnostic tests, such as visual field testing and electroretinography, to provide a comprehensive evaluation of a patient's visual function. Accurate interpretation of EOG results is crucial for diagnosing underlying conditions and guiding treatment options.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in EOG interpretation among practitioners
  • Need for correlation with clinical findings and other diagnostic tests
  • Potential overlap with other ocular and neurological conditions
  • Documentation requirements for abnormal findings

Audit Risk Factors

  • Inadequate documentation of clinical correlation with EOG results
  • Failure to specify the reason for the EOG test
  • Misuse of the code for normal EOG findings
  • Lack of supporting evidence for the diagnosis
