THELMA DIAZ, NP appears in the CMS NPPES registry as a Wound Care Registered Nurse provider holding NP credentials at 1626 MEDICAL CENTER DR STE 400, EL PASO, TX, 79902, with a listed phone of (915) 546-9200. NPI 1740404862 was issued on 04/12/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DIAZ 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 133 prescription claims written by this provider, covering 82 Medicare beneficiaries and totaling roughly $8K in drug spend, split 53% brand-name and 47% 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.

Wound Care Registered Nurse is a narrow specialty nationwide, with 602 enrolled providers across 54 states and an average of 1,085 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.
