Brellium Welcomes Dr. Andrey Ostrovsky, Former Medicaid Chief Medical Officer, as Strategic Advisor

We are excited to announce today that Dr. Andrey Ostrovsky, MD, will join Brellium as a strategic advisor.

Dr. Ostrovsky is the managing partner at Social Innovation Ventures, where he invests in and advises companies and non-profits dedicated to improving healthcare delivery and eliminating health disparities.

He previously served as the chief medical officer for the Center for Medicaid and Children's Health Insurance Program (CHIP) Services under both the Obama and first Trump administrations. In that role, he led the nation's largest health insurer — covering nearly 90 million Americans with an annual budget of nearly $600 billion — knowing when to push for efficiency and when to advocate for protecting critical coverage from fiscal cuts.

Dr. Ostrovsky will advise Brellium on compliance strategy, product development, and payer and provider relations as both parties work to improve the standard of healthcare. His appointment comes as providers face heightened enforcement activity and a rapidly shifting regulatory landscape, while payers navigate Medicaid work requirements, risk pool instability, and increased CMS audit scrutiny.

Dr. Ostrovsky brings a unique combination of insider experience and frontline clinical expertise. He has set policy at CMS, negotiated with state Medicaid programs, advocated on behalf of healthcare organizations navigating federal and state regulatory requirements, and personally run methadone clinics. He understands how compliance decisions get made at every level of the system — and how they land on the providers and payers who have to implement them.

"Andrey knows how this system works better than almost anyone — and he has spent his career fighting to make sure healthcare works for all involved: providers, payers, and, most critically, patients," said Zach Rosen, CEO, Brellium. "His perspective will make us better at both our mission and our business: advising compliance and quality."

"Documentation complexity and ambiguity get in the way of patient care," said Dr. Ostrovsky. "Brellium is on a mission to simplify compliance for all parties, so that payers and providers have a shared understanding of what quality looks like. Doctors know the care billed will be the care they're authorized to give. Patients don't have surprise denials down the road. I'm glad to be part of it." Dr. Ostrovsky holds a Medical Doctorate and undergraduate degrees in Chemistry and Psychology, Magna Cum Laude, from Boston University. He completed his pediatrics residency at Boston Medical Center and Boston Children's Hospital and served as a clinical instructor at Harvard Medical School. He is an attending physician at Mary's Center, a federally qualified health center, and has served on committees of the National Academies of Medicine, National Quality Forum, Institute for Healthcare Improvement, and the Commonwealth Fund.
