KAREN GABLER, ARNP appears in the CMS NPPES registry as a Oncology Registered Nurse provider holding ARNP credentials at 1003 S 5TH ST, TACOMA, WA, 98405, with a listed phone of (253) 403-1677. NPI 1285267757 was issued on 02/12/2020. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what GABLER 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 103 prescription claims written by this provider, covering 49 Medicare beneficiaries and totaling roughly $175K in drug spend, split 21% brand-name and 79% generic by claim count, with an opioid prescribing rate of 35.9%. 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 Registered Nurse is a narrow specialty nationwide, with 857 enrolled providers across 50 states and an average of 555 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.
