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).

COREY WELCHLIN, D.O. appears in the CMS NPPES registry as a Primary Podiatric Medicine Podiatrist provider holding D.O. credentials at 717 S STATE ST, FAIRMONT, MN, 56031, with a listed phone of (507) 238-4949. NPI 1649241977 was issued on 01/26/2006.

Medicare Part D records for calendar year 2023 show 144 prescription claims written by this provider, covering 50 Medicare beneficiaries and totaling roughly $2K in drug spend, with an opioid prescribing rate of 38.2%. 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.

Primary Podiatric Medicine Podiatrist is a narrow specialty nationwide, with 1,077 enrolled providers across 50 states and an average of 322 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.
