R94.118

Abnormal results of other function studies of eye

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

Code Description

ICD-10 R94.118 is a billable code used to indicate a diagnosis of abnormal results of other function studies of eye.

Key Diagnostic Point:

R94.118 is used to classify abnormal results from various function studies of the eye that do not fall under more specific categories. These studies may include visual field tests, electroretinography, and other specialized assessments that evaluate the functional capacity of the eye and its components. Abnormal findings can indicate a range of conditions, such as retinal diseases, optic nerve disorders, or systemic diseases affecting vision. Symptoms associated with these abnormalities may include blurred vision, visual field loss, or difficulty with color perception. Clinicians often utilize these tests to diagnose conditions like glaucoma, diabetic retinopathy, or macular degeneration. Accurate interpretation of these results is crucial for determining the appropriate management and treatment plan for the patient.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of tests that can yield abnormal results
  • Need for precise documentation of test types and results
  • Differentiation from other eye-related codes
  • Potential overlap with other conditions affecting vision

Audit Risk Factors

  • Insufficient documentation of the specific function study performed
  • Lack of correlation between test results and clinical findings
  • Inconsistent use of the code across different providers
  • Failure to specify the nature of the abnormality

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Documentation should include the type of function study performed, results, and any relevant patient history or symptoms.

Common Clinical Scenarios

Patients presenting with visual disturbances or systemic conditions that may affect vision, such as diabetes or hypertension.

Billing Considerations

Ensure that the relationship between systemic diseases and eye function studies is clearly documented.

Emergency Medicine

Documentation Requirements

Acute care documentation must detail the immediate findings from function studies and any interventions taken.

Common Clinical Scenarios

Patients with sudden vision loss or acute eye injuries requiring immediate assessment.

Billing Considerations

Rapid documentation is essential; ensure that all findings are recorded promptly to support the diagnosis.

Coding Guidelines

Inclusion Criteria

Use R94.118 When
  • Follow official ICD
  • CM coding guidelines, ensuring that the code is used only when the results of function studies are abnormal and not classified elsewhere
  • Document the specific tests performed and their results to support the use of this code

Clinical Scenario

Used when a patient presents with symptoms of visual field loss and requires a comprehensive assessment.

Documentation Requirements

Document the specific findings from the visual field test and correlate them with the patient's symptoms.

Specialty Considerations

Ophthalmologists should ensure that all relevant findings are included in the report.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of abnormal results from function studies, improving the granularity of data collected for eye-related conditions. This specificity aids in better tracking of patient outcomes and resource allocation.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of abnormal results from function studies, improving the granularity of data collected for eye-related conditions. This specificity aids in better tracking of patient outcomes and resource allocation.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding of abnormal results from function studies, improving the granularity of data collected for eye-related conditions. This specificity aids in better tracking of patient outcomes and resource allocation.
