ARTURO ALVARADO, AGPCNP-BC, ACCNS-AG appears in the CMS NPPES registry as a Critical Care Medicine Clinical Nurse Specialist provider holding AGPCNP-BC, ACCNS-AG credentials at 620 JOHN PAUL JONES CIR, PORTSMOUTH, VA, 23708, with a listed phone of (757) 953-3420. NPI 1295227502 was issued on 06/01/2018. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ALVARADO 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 prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal — many Critical Care Medicine Clinical Nurse Specialist providers operate outside Part D entirely.

Critical Care Medicine Clinical Nurse Specialist is a narrow specialty nationwide, with 211 enrolled providers across 34 states and an average of 963 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.
