ALEXANDER BATEN-TSCHAN appears in the CMS NPPES registry as a Glaucoma Specialist (Ophthalmology) Physician provider at 6720A ROCKLEDGE DR STE 200, BETHESDA, MD, 20817, with a listed phone of (301) 493-9600. NPI 1205333457 was issued on 04/12/2018. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BATEN-TSCHAN most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 5,711 prescription claims written by this provider, covering 1,207 Medicare beneficiaries and totaling roughly $576K in drug spend, split 27% brand-name and 73% generic by claim count. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 85.4852/100 for the 2023 performance year (Quality 73.6095), compared with the national average of 83.1.

Glaucoma Specialist (Ophthalmology) Physician is a narrow specialty nationwide, with 354 enrolled providers across 42 states and an average of 2,962 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
