MICHAEL HATTAN, OD appears in the CMS NPPES registry as a Corneal and Contact Management Optometrist provider holding OD credentials at 1517 E 27TH ST, HAYS, KS, 67601, with a listed phone of (785) 625-2226. NPI 1639128861 was issued on 05/06/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what HATTAN 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 396 prescription claims written by this provider, covering 93 Medicare beneficiaries and totaling roughly $36K in drug spend, split 28% brand-name and 72% 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 99.8129/100 for the 2023 performance year (Quality 99.6258), compared with the national average of 83.1.

Corneal and Contact Management Optometrist is a narrow specialty nationwide, with 1,549 enrolled providers across 52 states and an average of 235 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
