Documentation Required
- Document general ophthalmoscopy and biomicroscopy findings in the medical record even when these services are included in extended ophthalmoscopy and not separately billed.

- CPT 92227 is covered when used to evaluate asymptomatic patients at risk with known disease likely to cause retinal disease (e.g., diabetes mellitus) when ordered by the treating physician.
- CPT 92228 is a covered service when ordered by the treating physician or other treating practitioner acting within the scope of license and Medicare requirements.
