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).

TAMBREA JOHNSON, PHARMACIST, PTA appears in the CMS NPPES registry as a Physical Therapy Assistant provider holding PHARMACIST, PTA credentials at 1324 GROVE PARK DR, ORANGEBURG, SC, 29115, with a listed phone of (803) 536-0007. NPI 1417224353 was issued on 11/21/2011.

Medicare Part D records for calendar year 2023 show 31 prescription claims written by this provider, covering 31 Medicare beneficiaries and totaling roughly $6K in drug spend, split 100% brand-name and 0% generic by claim count.

Physical Therapy Assistant is a high-volume specialty nationwide, with 60,025 enrolled providers across 55 states and an average of 704 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.
