ALFRED LONSER, M.D. appears in the CMS NPPES registry as a Anesthesiology Physician provider holding M.D. credentials at 4100 LAKE OTIS PKWY STE 216, ANCHORAGE, AK, 99508, with a listed phone of (907) 563-2873. NPI 1245240308 was issued on 08/09/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what LONSER 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 1,785 prescription claims written by this provider, covering 205 Medicare beneficiaries and totaling roughly $105K in drug spend, split 5% brand-name and 95% generic by claim count, with an opioid prescribing rate of 53.4%. 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 77.5873/100 for the 2023 performance year (Quality 51.2497), compared with the national average of 83.1.

Anesthesiology Physician is a high-volume specialty nationwide, with 56,398 enrolled providers across 56 states and an average of 860 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.
