Abnormal electroretinogram [ERG]
ICD-10 R94.111 is a billable code used to indicate a diagnosis of abnormal electroretinogram [erg].
An abnormal electroretinogram (ERG) indicates a deviation from normal retinal function as assessed by this specialized test. The ERG measures the electrical responses of the retina's light-sensitive cells (photoreceptors) when exposed to light stimuli. Abnormal findings may suggest various retinal disorders, including retinitis pigmentosa, diabetic retinopathy, or other inherited retinal diseases. Symptoms associated with abnormal ERG results can include visual disturbances, night blindness, or peripheral vision loss. Clinicians often utilize ERG in conjunction with other diagnostic tests, such as optical coherence tomography (OCT) or visual field testing, to provide a comprehensive evaluation of retinal health. The interpretation of ERG results requires expertise, as variations can arise from factors such as patient age, systemic conditions, and medication effects. Accurate coding of R94.111 is essential for proper documentation of retinal dysfunction and guiding further management.
Detailed patient history, including symptoms and previous ocular conditions, must be documented to support the diagnosis.
Patients presenting with visual disturbances or systemic diseases affecting vision.
Consideration of systemic conditions that may influence retinal health, such as diabetes or hypertension.
Acute care documentation must include immediate symptoms and any prior ocular history.
Patients with sudden vision loss or acute eye injuries requiring ERG for assessment.
Rapid assessment and documentation are critical in emergency settings to ensure appropriate follow-up.
Used when performing an ERG to assess retinal function.
Document the indication for the ERG and any relevant patient history.
Ophthalmology specialists should ensure proper coding based on the findings.
An abnormal ERG indicates potential dysfunction in the retina, which may be due to various conditions such as inherited retinal diseases, diabetic retinopathy, or other retinal pathologies.
