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).

REBECCA PERLOW, D.O. is a Obstetrics Physician provider practicing in TARZANA, California, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: D.O..

REBECCA PERLOW, D.O. appears in the CMS NPPES registry as a Obstetrics Physician provider holding D.O. credentials at 5525 ETIWANDA AVE, TARZANA, CA, 91356, with a listed phone of (818) 344-8822. NPI 1346235157 was issued on 09/19/2005.

Medicare Part D records for calendar year 2023 show 204 prescription claims written by this provider, covering 18 Medicare beneficiaries and totaling roughly $16K in drug spend.

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.
