ARTHUR KATZ, M.D. appears in the CMS NPPES registry as a Otolaryngology Physician provider holding M.D. credentials at 1950 45TH STREET, MUNSTER, IN, 46321, with a listed phone of (219) 934-9396. NPI 1417944109 was issued on 09/29/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what KATZ 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 3,148 prescription claims written by this provider, covering 657 Medicare beneficiaries and totaling roughly $290K in drug spend, split 7% brand-name and 93% 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 72.7551/100 for the 2023 performance year (Quality 51.6667, Cost 65.559), compared with the national average of 83.1.

Otolaryngology Physician is a mid-sized specialty nationwide, with 10,895 enrolled providers across 54 states and an average of 509 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. 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.
