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 Dermatology Physician. 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).
Alan Berlin, DO appears in the CMS NPPES registry as a Dermatology Physician provider holding DO credentials at 1079 PROFESSIONAL DR, Flint, MI, 48532, with a listed phone of (810) 732-3330. NPI 1689759839 was issued on 10/26/2006.
Medicare Part D records for calendar year 2023 show 1,242 prescription claims written by this provider, covering 350 Medicare beneficiaries and totaling roughly $795K in drug spend, split 13% brand-name and 87% generic by claim count.
Dermatology Physician is a mid-sized specialty nationwide, with 14,645 enrolled providers across 53 states and an average of 729 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.

- Weigh a second option: compare this provider with a nearby Dermatology Physician peer on Medicare volume and prescribing patterns. Compare providers
