About 92018: Comprehensive eye examination under anesthesia
A comprehensive ophthalmic assessment performed under general anesthesia when a complete, reliable examination cannot be obtained while the patient is awake.
An ophthalmologist performs a full diagnostic eye assessment while the patient is under general anesthesia, allowing evaluation when a reliable examination cannot be completed awake. Common situations include a young child or a patient with significant developmental, behavioral, or physical limitations. The examination may take place in an operating room or another anesthesia-capable setting, and may include manipulation of the globe when needed for diagnostic or therapeutic purposes. This service is broader than a limited anesthetized eye examination.
Select 92018 when the documented ophthalmic work is comprehensive rather than a targeted check of one problem. Record why anesthesia was needed, which examination elements were completed, the findings, and any manipulation or treatment performed. The anesthesia setting alone does not establish the comprehensive level; the scope of the eye examination does. Document the service as a comprehensive assessment rather than splitting its routine examination observations among separate eye-exam codes. A limited examination under anesthesia is reported with 92019.

92018 billing questions
When should 92018 be chosen over 92019?
Use 92018 for a comprehensive ophthalmic assessment under anesthesia. Use 92019 when the anesthetized examination is limited in scope.
Does the patient have to be a child?
No. The relevant circumstance is the need for general anesthesia to obtain the documented examination, not the patient's age.
Does 92018 include the anesthesia service?
No. 92018 represents the ophthalmologist's examination; the anesthesia professional's service is separate.
Does general anesthesia itself require a modifier?
General anesthesia alone is not a reason to append a modifier to 92018.
What documentation supports reporting 92018?
Document why an examination while awake was not feasible, the scope of the comprehensive eye assessment, the findings, and any globe manipulation or treatment performed.
