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).

JUNG PARK, MD is a Adult Medicine Physician provider practicing in WHITWELL, Tennessee, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD. NPI: 1942291638.

JUNG PARK, MD appears in the CMS NPPES registry as a Adult Medicine Physician provider holding MD credentials at 13851 HIGHWAY 28, WHITWELL, TN, 37397, with a listed phone of (423) 658-9200. NPI 1942291638 was issued on 11/02/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what PARK 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 14,023 prescription claims written by this provider, covering 394 Medicare beneficiaries and totaling roughly $977K in drug spend, split 22% brand-name and 78% generic by claim count, with an opioid prescribing rate of 3.0%.

Adult Medicine Physician is a narrow specialty nationwide, with 2,481 enrolled providers across 52 states and an average of 2,807 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.
