ROSANGELA FERNANDEZ MEDERO, MD appears in the CMS NPPES registry as a Critical Care Medicine (Internal Medicine) Physician provider holding MD credentials at 100 AVE LUIS MUNOZ MARIN, CAGUAS, PR, 00725, with a listed phone of (939) 204-0800. NPI 1568565893 was issued on 09/05/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what FERNANDEZ MEDERO 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 7,944 prescription claims written by this provider, covering 750 Medicare beneficiaries and totaling roughly $1.7 million in drug spend, with an opioid prescribing rate of 0.2%. 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.

Critical Care Medicine (Internal Medicine) Physician is a mid-sized specialty nationwide, with 6,631 enrolled providers across 53 states and an average of 1,069 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.
