CHELSEA DALLMAN, ARNP appears in the CMS NPPES registry as a Psychiatric/Mental Health Nurse Practitioner provider holding ARNP credentials at 165 E HAWTHORNE AVE, COLVILLE, WA, 99114, with a listed phone of (509) 684-4597. NPI 1689056269 was issued on 06/19/2015. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DALLMAN 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 238 prescription claims written by this provider, covering 43 Medicare beneficiaries and totaling roughly $48K in drug spend, split 13% brand-name and 87% generic by claim count. 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.

Psychiatric/Mental Health Nurse Practitioner is a mid-sized specialty nationwide, with 39,953 enrolled providers across 54 states and an average of 927 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.
