• Glaucoma Diagnoses for Anterior Segment OCT


    Question: If our doctor performs CPT code 92132 Anterior Segment OCT for evaluation of anatomical narrow angles or narrow angle glaucoma, what diagnosis do we use?

    Answer: The list of diagnosis codes varies by payer. Check your payer coverage policy. If the patient has Medicare Part B and you are unsure of coverage, obtain an advance beneficiary notice and append modifier -GA to the test. You can find Medicare policies at aao.org/LCDs.
