YAW ASAMOAH, PA-C appears in the CMS NPPES registry as a Physician Assistant provider holding PA-C credentials at 6309 CAMELBACK LN, FONTANA, CA, 92336, with a listed phone of (213) 804-9776. NPI 1083917439 was issued on 12/07/2010. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ASAMOAH 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 4,515 prescription claims written by this provider, covering 481 Medicare beneficiaries and totaling roughly $359K 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 58.9662/100 for the 2023 performance year (Quality 0, Cost 43.2207), compared with the national average of 83.1.

Physician Assistant is a high-volume specialty nationwide, with 149,975 enrolled providers across 56 states and an average of 790 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.
