CHRISTIE SIBIGA, AGACNP-BC appears in the CMS NPPES registry as a Acute Care Nurse Practitioner provider holding AGACNP-BC credentials at 14961 W BELL RD, SURPRISE, AZ, 85374, with a listed phone of (623) 242-9830. NPI 1679194153 was issued on 05/06/2020. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SIBIGA 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 167 prescription claims written by this provider, covering 42 Medicare beneficiaries and totaling roughly $40K in drug spend, split 47% brand-name and 53% 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.

Acute Care Nurse Practitioner is a mid-sized specialty nationwide, with 24,583 enrolled providers across 53 states and an average of 576 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.
