JUSTIN GUZMAN appears in the CMS NPPES registry as a Physician Assistant provider at 2500 E CAPITOL DR STE 2500, APPLETON, WI, 54911, with a listed phone of (920) 831-5050. NPI 1912230954 was issued on 09/09/2009. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what GUZMAN 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 348 prescription claims written by this provider, covering 201 Medicare beneficiaries and totaling roughly $5K in drug spend, with an opioid prescribing rate of 4.3%. 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.

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.
