WILLIAM ALEXANDER, MD, PHD appears in the CMS NPPES registry as a Hospice and Palliative Medicine (Internal Medicine) Physician provider holding MD, PHD credentials at ELM AND CARLTON ST, BUFFALO, NY, 14263, with a listed phone of (716) 845-2300. NPI 1114585379 was issued on 06/03/2019. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ALEXANDER 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 371 prescription claims written by this provider, covering 111 Medicare beneficiaries and totaling roughly $17K in drug spend, split 5% brand-name and 95% generic by claim count, with an opioid prescribing rate of 37.2%. 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.

Hospice and Palliative Medicine (Internal Medicine) Physician is a narrow specialty nationwide, with 1,524 enrolled providers across 51 states and an average of 1,275 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.
