R94.113

Abnormal oculomotor study

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

Code Description

ICD-10 R94.113 is a billable code used to indicate a diagnosis of abnormal oculomotor study.

Key Diagnostic Point:

An abnormal oculomotor study indicates that the results of tests assessing the function of the oculomotor nerve, which controls eye movements, are outside the normal range. This may manifest as issues with eye alignment, movement, or coordination, potentially leading to symptoms such as diplopia (double vision), strabismus (misalignment of the eyes), or difficulty with visual tracking. Abnormal findings can arise from various conditions, including neurological disorders, trauma, or systemic diseases affecting the nervous system. The oculomotor study typically involves a series of tests, including assessments of eye movements, pupil response, and the ability to maintain fixation. Clinicians may utilize this code when the results of these tests reveal abnormalities that are not classified elsewhere, guiding further diagnostic evaluation and management.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying conditions that can cause abnormal results
  • Need for comprehensive documentation of clinical findings
  • Potential overlap with other neurological symptoms
  • Variability in test methodologies and interpretations

Audit Risk Factors

  • Insufficient documentation of the clinical rationale for the oculomotor study
  • Failure to specify the nature of the abnormal findings
  • Inconsistent coding of related neurological symptoms
  • Lack of correlation between the study results and the patient's clinical picture
