Board certification

Not published by CMS

CMS does not publish a per-provider board-certification field in NPPES. PlainDoctor does not have a reliable per-specialty certification rate to show for Surgery Physician. Verify directly:

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).

Ray Gervacio Blanco, MD appears in the CMS NPPES registry as a Surgery Physician provider holding MD credentials at 6569 N CHARLES ST, Baltimore, MD, 21204, with a listed phone of (443) 849-8940. NPI 1891773966 was issued on 01/09/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Blanco 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 71 prescription claims written by this provider, covering 35 Medicare beneficiaries and totaling roughly $1K in drug spend. 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.

Surgery Physician is a mid-sized specialty nationwide, with 36,191 enrolled providers across 56 states and an average of 169 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.

  • Confirm the NPI record is current in the official CMS registry, providers update their own NPPES details, and moves can lag. Verify this NPI
  • Check the active license and any disciplinary history with the Maryland medical board, federal registration is not a license check. Credential verification guide
  • Weigh a second option: compare this provider with a nearby Surgery Physician peer on Medicare volume and prescribing patterns. Compare providers
