Abby Newsom appears in the CMS NPPES registry as a Medical Oncology Physician provider at 3991 DUTCHMANS LN STE 405, Louisville, KY, 40207, with a listed phone of (502) 899-3366. NPI 1598654519 was issued on 07/02/2025.

Medicare Part D prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal, many Medical Oncology Physician providers operate outside Part D entirely.

Medical Oncology Physician is a narrow specialty nationwide, with 3,792 enrolled providers across 53 states and an average of 689 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
