PATRICK MAHON, ACNPC-AG, PMHNP-BC appears in the CMS NPPES registry as a Critical Care Medicine Registered Nurse provider holding ACNPC-AG, PMHNP-BC credentials at 202 MAIN ST STE 4, REISTERSTOWN, MD, 21136, with a listed phone of (410) 449-0182. NPI 1124610928 was issued on 02/03/2021. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MAHON 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 42 prescription claims written by this provider, covering 11 Medicare beneficiaries and totaling roughly $755 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 76.5856/100 for the 2023 performance year (Quality 64.5647, Cost 48.5487), compared with the national average of 83.1.

Critical Care Medicine Registered Nurse is a mid-sized specialty nationwide, with 6,529 enrolled providers across 53 states and an average of 752 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
