GLENN KERSHEN, MD appears in the CMS NPPES registry as a Urology Physician provider holding MD credentials at 1117 S WASHINGTON AVE, SAGINAW, MI, 48601, with a listed phone of (989) 791-4020. NPI 1013900190 was issued on 08/24/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what KERSHEN 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 11,493 prescription claims written by this provider, covering 3,143 Medicare beneficiaries and totaling roughly $3.2 million in drug spend, with an opioid prescribing rate of 0.5%. 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 75/100 for the 2023 performance year, compared with the national average of 83.1.

Urology Physician is a mid-sized specialty nationwide, with 13,350 enrolled providers across 54 states and an average of 1,280 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
