IRENE NJUGUNA, AGNP appears in the CMS NPPES registry as a Gerontology Nurse Practitioner provider holding AGNP credentials at 4307 SILVER SPRING RD, PERRY HALL, MD, 21128, with a listed phone of (410) 948-5355. NPI 1255893061 was issued on 04/01/2019.

Medicare Part D records for calendar year 2023 show 990 prescription claims written by this provider, covering 137 Medicare beneficiaries and totaling roughly $50K in drug spend, with an opioid prescribing rate of 31.0%. 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 96.7888/100 for the 2023 performance year (Quality 100, Cost 55.9627), compared with the national average of 83.1.

Gerontology Nurse Practitioner is a mid-sized specialty nationwide, with 9,625 enrolled providers across 54 states and an average of 1,283 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
