PHOEBE CHONGONG, NP appears in the CMS NPPES registry as a Primary Care Nurse Practitioner provider holding NP credentials at 10300 CRYSTAL BROOK CT, UPPER MARLBORO, MD, 20772, with a listed phone of (240) 271-5078. NPI 1194336941 was issued on 08/14/2020.

Medicare Part D records for calendar year 2023 show 128 prescription claims written by this provider, covering 71 Medicare beneficiaries and totaling roughly $12K in drug spend. 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 76.2694/100 for the 2023 performance year (Quality 71.9183, Cost 48.9797), compared with the national average of 83.1.

Primary Care Nurse Practitioner is a mid-sized specialty nationwide, with 10,138 enrolled providers across 54 states and an average of 1,363 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.
