ELIZABETH BUMBER, MHS, PA-C appears in the CMS NPPES registry as a Medical Physician Assistant provider holding MHS, PA-C credentials at 2501 KUSER RD STE 3, HAMILTON, NJ, 08691, with a listed phone of (609) 896-0444. NPI 1649507005 was issued on 11/05/2009.

Medicare Part D records for calendar year 2023 show 52 prescription claims written by this provider, covering 42 Medicare beneficiaries and totaling roughly $1K in drug spend, with an opioid prescribing rate of 51.9%. 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 58.2388/100 for the 2023 performance year (Quality 35.5326, Cost 45.2633), compared with the national average of 83.1.

Medical Physician Assistant is a mid-sized specialty nationwide, with 40,527 enrolled providers across 55 states and an average of 1,077 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
