White Collar Criminal & Federal Defense Attorneys Trusted Nationwide
Allegations involving Risk Adjustment and Medicare Advantage fraud strike at the core of a healthcare organization’s financial viability and professional credibility. These are not routine compliance issues or technical disputes—they are high-stakes enforcement matters that can result in crushing financial penalties, exclusion from federal healthcare programs, and criminal prosecution.

In a regulatory environment where data analytics, retrospective audits, and whistleblowers drive aggressive enforcement, experienced legal defense is not optional. It is essential.
At Chapman, Dowling & Mallek, we defend healthcare professionals and organizations facing some of the most complex and consequential Medicare Advantage investigations in the country—quietly, strategically, and with precision.
