Louise Casa, CRNP appears in the CMS NPPES registry as a Nurse Practitioner provider holding CRNP credentials at 700 2ND ST NE, Washington, DC, 20002, with a listed phone of (202) 346-3000. NPI 1417001389 was issued on 01/22/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Casa 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 478 prescription claims written by this provider, covering 116 Medicare beneficiaries and totaling roughly $97K in drug spend, split 47% brand-name and 38% 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.

Nurse Practitioner is a high-volume specialty nationwide, with 87,227 enrolled providers across 56 states and an average of 1,084 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
