COLLEEN VALENTI, REGISTERED NURSE appears in the CMS NPPES registry as a Oncology Registered Nurse provider holding REGISTERED NURSE credentials at 4440 W 95TH ST, OAK LAWN, IL, 60453, with a listed phone of (708) 684-4694. NPI 1801507116 was issued on 12/07/2022. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what VALENTI 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 119 prescription claims written by this provider, covering 52 Medicare beneficiaries and totaling roughly $117K in drug spend, split 13% brand-name and 87% generic by claim count, with an opioid prescribing rate of 21.8%. 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.
