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).

DOUGLAS ROBERTS, M.D. is a General Practice Physician provider practicing in IRMO, South Carolina, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D.. NPI: 1154367597. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry. Provider information is self-reported to CMS and updated monthly.

DOUGLAS ROBERTS, M.D. appears in the CMS NPPES registry as a General Practice Physician provider holding M.D. credentials at 7182 WOODROW ST STE 200, IRMO, SC, 29063, with a listed phone of (803) 749-1111. NPI 1154367597 was issued on 06/22/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ROBERTS 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 10,064 prescription claims written by this provider, covering 614 Medicare beneficiaries and totaling roughly $1.2 million in drug spend, split 14% brand-name and 86% generic by claim count, with an opioid prescribing rate of 1.4%.

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.
