AMBER CAMPBELL, D.O. appears in the CMS NPPES registry as a General Practice Physician provider holding D.O. credentials at 1771 COMMERCIAL ST, WARSAW, MO, 65355, with a listed phone of (660) 438-5193. NPI 1689804437 was issued on 07/14/2009. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CAMPBELL 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 15,483 prescription claims written by this provider, covering 614 Medicare beneficiaries and totaling roughly $1.7 million in drug spend, split 14% brand-name and 86% generic by claim count, with an opioid prescribing rate of 4.2%. 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.

General Practice Physician is a mid-sized specialty nationwide, with 16,677 enrolled providers across 56 states and an average of 2,872 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.
