Brellium Taps Former Medicaid Chief to Navigate Regulatory Maze

NEW YORK, NY – May 07, 2026 – In a move that signals a deepening convergence of federal policy expertise and private-sector innovation, AI-powered compliance platform Brellium has appointed Dr. Andrey Ostrovsky as a strategic advisor. Dr. Ostrovsky, who served as the Chief Medical Officer for the Center for Medicaid and CHIP Services (CMS) across two presidential administrations, brings a formidable depth of regulatory knowledge to the rapidly growing health tech firm.

The appointment is a significant development for Brellium, which provides an AI-driven platform used by over 200 healthcare organizations to automate clinical compliance. It also highlights a broader industry trend where deep policy insight is becoming a crucial asset for companies aiming to solve the intractable administrative challenges plaguing the U.S. healthcare system.

The Strategic Value of a Policy Insider

For a company like Brellium, which operates at the complex intersection of clinical care, billing, and regulation, Dr. Ostrovsky’s experience is more than just a notable addition to an advisory board; it represents a powerful strategic advantage. During his tenure at CMS, he was a key figure overseeing policy for the nation's largest health insurer, covering nearly 90 million Americans. His work involved navigating the intricate relationships between federal regulators, state Medicaid programs, and the vast network of providers delivering care.

Brellium, which recently bolstered its growth with a $16.7 million Series A funding round, has built its business on creating an AI engine that audits 100% of patient visits against a labyrinth of payer and regulatory rules. The goal is to identify and correct documentation errors before they lead to costly claim denials or payer clawbacks—a problem so central to their model that the company offers a clawback guarantee for any chart its platform approves. Having an advisor who helped write and enforce the very rules their system deciphers could provide an unparalleled edge.

"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 of Brellium, in a statement. "His perspective will make us better at both our mission and our business."

Dr. Ostrovsky’s influence is expected to shape Brellium's product roadmap, enabling the platform to not only react to current regulations but also anticipate future policy shifts. This proactive capability could prove invaluable to clients like Grow Therapy, Headspace, and Graham Healthcare Group as they navigate an environment of heightened enforcement and evolving payment models.

Building a ‘Shared Source of Truth’

The fundamental friction between healthcare payers and providers often stems from a lack of shared understanding. Different interpretations of complex billing codes, documentation requirements, and medical necessity criteria create a cycle of denials, appeals, and administrative waste that burdens the entire system. Brellium's stated mission is to become the 'shared source of truth' that bridges this divide, and Dr. Ostrovsky is seen as a key architect in that effort.

His unique background, which combines high-level policy work with frontline clinical experience operating methadone clinics, gives him a rare 360-degree view of the problem. He has seen how policy decisions made in Washington translate into real-world challenges for providers and, ultimately, patients.

"Documentation complexity and ambiguity get in the way of patient care," Dr. Ostrovsky stated. He emphasized that a shared understanding of quality allows doctors to focus on care with confidence that it will be authorized, while patients are protected from surprise denials. His role at Brellium is to help embed this principle into the technology.

The concept of a shared source of truth is a lofty goal in a fragmented industry. However, by leveraging AI to provide a consistent, real-time interpretation of the rules for every patient encounter, platforms like Brellium aim to create a de facto standard. This reduces ambiguity and allows both parties to operate from a common playbook, turning confrontational audits into collaborative quality assurance.

Navigating a Minefield of Regulatory Scrutiny

Dr. Ostrovsky’s appointment is particularly timely given the current healthcare landscape. Federal and state regulators are intensifying their scrutiny of healthcare spending, deploying sophisticated data analytics to root out fraud, waste, and abuse. The rapid expansion of telehealth during the pandemic has created a new frontier for compliance, with regulators now closely examining billing practices and documentation for virtual care.

Providers face a difficult balancing act: they must deliver care efficiently while ensuring every chart is perfectly documented to withstand potential audits from a growing list of entities, including Medicare Administrative Contractors (MACs) and Recovery Audit Contractors (RACs). Simultaneously, payers are under pressure to manage risk pools and ensure program integrity, especially within Medicaid managed care, leading to more stringent reviews.

An advisor with Dr. Ostrovsky’s background can help Brellium fine-tune its platform to address these specific pressure points. His insights into how CMS identifies audit targets and what constitutes sufficient documentation can be translated into the platform’s algorithms, effectively creating an automated defense system for providers. This expertise is critical for helping organizations stay compliant, reduce their risk exposure, and secure their revenue cycle in an era of heightened oversight.

The 'Revolving Door' in Health Tech

The transition of high-level government officials into the private sector, often termed the 'revolving door,' is a well-established phenomenon in Washington, and the health tech industry is no exception. Such moves often spark debate, raising questions about influence and fairness. While some critics may view these appointments with skepticism, proponents argue they are essential for driving meaningful innovation in highly regulated fields.

In this case, Dr. Ostrovsky's move to advise a firm like Brellium can be seen as a way to operationalize his public sector goals on a different scale. Having worked to improve the healthcare system from within the government, he now brings that same mission to a technology company aiming to solve systemic inefficiencies from the outside. The argument is that an individual with deep institutional knowledge is uniquely positioned to help build solutions that are not just technologically impressive but also practically effective and policy-aware.

For the health tech sector, attracting former regulators is a strategy to ensure products are not developed in a vacuum. Without this insider expertise, startups risk building solutions that are misaligned with complex payment rules or clinical workflows, dooming them to failure. By embedding that knowledge directly into their strategic core, companies like Brellium hope to accelerate the development of tools that genuinely reduce administrative burden and allow providers to focus more on patient care. This partnership exemplifies a modern approach to tackling healthcare's biggest challenges, where public sector experience directly fuels private sector solutions.
