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 Ph.D. Medical Genetics. Verify directly:
How MIPS and board certification work
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).
Rim Marcinkus, M.D. appears in the CMS NPPES registry as a Ph.D. Medical Genetics provider holding M.D. credentials at 35280 BOB HOPE DR, Rancho Mirage, CA, 92270, with a listed phone of (760) 202-4481. NPI 1275678583 was issued on 02/21/2007.
Medicare Part D records for calendar year 2023 show 80 prescription claims written by this provider, covering 22 Medicare beneficiaries and totaling roughly $822 in drug spend, with an opioid prescribing rate of 21.3%.
Ph.D. Medical Genetics is a narrow specialty nationwide, with 357 enrolled providers across 46 states and an average of 984 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.

Use this federal record as your verification checklist, not as a recommendation.
- 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 California medical board, federal registration is not a license check. Credential verification guide
- Weigh a second option: compare this provider with a nearby Ph.D. Medical Genetics peer on Medicare volume and prescribing patterns. Compare providers
