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).

Roseanne Papoyan, PHARM. D. appears in the CMS NPPES registry as a Pharmacist provider holding PHARM. D. credentials at 1253 VINE ST, Los Angeles, CA, 90038, with a listed phone of (818) 334-3772. NPI 1245304773 was issued on 11/17/2006.

Medicare Part D records for calendar year 2023 show 34 prescription claims written by this provider, covering 24 Medicare beneficiaries and totaling roughly $8K in drug spend, split 100% brand-name and 0% generic by claim count.

Pharmacist is a high-volume specialty nationwide, with 290,447 enrolled providers across 56 states and an average of 135 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.
