SUSAN STARR, N.P., C.N.S. appears in the CMS NPPES registry as a Oncology Clinical Nurse Specialist provider holding N.P., C.N.S. credentials at 3285 SKYPARK DR, TORRANCE, CA, 90505, with a listed phone of (310) 750-3300. NPI 1790936649 was issued on 10/08/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what STARR 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 816 prescription claims written by this provider, covering 259 Medicare beneficiaries and totaling roughly $900K in drug spend, split 20% brand-name and 80% generic by claim count, with an opioid prescribing rate of 5.5%. 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.

Oncology Clinical Nurse Specialist is a narrow specialty nationwide, with 209 enrolled providers across 38 states and an average of 435 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.
