BIANCA RULLAN OLIVER, M.D. appears in the CMS NPPES registry as a Otolaryngology Physician provider holding M.D. credentials at 735 AVE PONCE DE LEON STE 512, SAN JUAN, PR, 00917, with a listed phone of (787) 751-1910. NPI 1053780387 was issued on 09/16/2015. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what RULLAN OLIVER 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 629 prescription claims written by this provider, covering 156 Medicare beneficiaries and totaling roughly $55K in drug spend, split 2% brand-name and 98% 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.

Otolaryngology Physician is a mid-sized specialty nationwide, with 10,895 enrolled providers across 54 states and an average of 509 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.
