TAHIR ZAMAN appears in the CMS NPPES registry as a Nephrology Physician provider at 1250 E 3900 S STE 410, SALT LAKE CITY, UT, 84124, with a listed phone of (801) 281-5996. NPI 1508182437 was issued on 04/16/2010. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ZAMAN 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 988 prescription claims written by this provider, covering 234 Medicare beneficiaries and totaling roughly $190K in drug spend. 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 92.0664/100 for the 2023 performance year (Quality 85.5753), compared with the national average of 83.1.

Nephrology Physician is a mid-sized specialty nationwide, with 10,534 enrolled providers across 55 states and an average of 1,454 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
