ONEIL BETRRAND, R.PH appears in the CMS NPPES registry as a Pharmacotherapy Pharmacist provider holding R.PH credentials at 10107 S CALUMET AVE, CHICAGO, IL, 60628, with a listed phone of (773) 931-9595. NPI 1578848321 was issued on 10/12/2011. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BETRRAND 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 16 prescription claims written by this provider, covering 16 Medicare beneficiaries and totaling roughly $4K in drug spend, split 100% brand-name and 0% generic by claim count. 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.

Pharmacotherapy Pharmacist is a mid-sized specialty nationwide, with 5,925 enrolled providers across 53 states and an average of 397 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.
