The Merit-based Incentive Payment System (MIPS) scores providers 0–100 across four performance categories: Quality, Cost, Promoting Interoperability, and Improvement Activities, weighted under 42 CFR §414.1380. Reporting is voluntary for many small practices, so absence of a MIPS score is not a quality signal.

Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus continuous Maintenance of Certification cycles. Verify any individual provider's status through certificationmatters.org (ABMS) or osteopathic.org (AOA).

AMANDA ANDERSEN is a Internal Medicine Physician provider practicing in BEAVERTON, Oregon, according to the CMS National Plan and Provider Enumeration System (NPPES). NPI: 1033504410. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry. Provider information is self-reported to CMS and updated monthly.

AMANDA ANDERSEN appears in the CMS NPPES registry as a Internal Medicine Physician provider at 4855 SW WESTERN AVE, BEAVERTON, OR, 97005, with a listed phone of (503) 813-2000. NPI 1033504410 was issued on 04/01/2015. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ANDERSEN 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 1,231 prescription claims written by this provider, covering 311 Medicare beneficiaries and totaling roughly $89K in drug spend, split 12% brand-name and 88% generic by claim count, with an opioid prescribing rate of 4.7%. 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.

Internal Medicine Physician is a high-volume specialty nationwide, with 172,858 enrolled providers across 56 states and an average of 2,716 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.
