Question: When can we start using the new retina and glaucoma taxonomy specialty designations? Codify Subscriber Answer: As many practices are aware, CMS has released new taxonomy codes for ophthalmology subspecialists, which are now active. Therefore, when these practitioners submit Medicare claims, they can self-designate whether they specialize in oculoplastics, uveitis, retina, or glaucoma. To make this adjustment, you’ll have to log into the National Plan and Provider Enumeration System (NPPES) and update your doctors’ taxonomy codes to match one of the following: Unfortunately, not every insurer is going to recognize those subspecialties, so some ophthalmologists are better off remaining listed with the standard ophthalmology taxonomy code. You should contact your top payers to ask how they handle this, and then make the determination of whether it’s worth your while to make the change or not.
