JOY AHANONU, CRNP appears in the CMS NPPES registry as a Acute Care Nurse Practitioner provider holding CRNP credentials at 4 W ROLLING CROSS RD STE 100, CATONSVILLE, MD, 21228, with a listed phone of (410) 869-0100. NPI 1588837090 was issued on 04/04/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what AHANONU 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 1,915 prescription claims written by this provider, covering 245 Medicare beneficiaries and totaling roughly $160K in drug spend, split 8% brand-name and 92% 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.
