Representative Matters
- Represented Medicare Advantage organization in first-of-its kind challenge to 2024 Star Ratings based upon CMS’s failure to comply with federal regulations regarding the calculation of Star Ratings. The court found in favor of the plan and required CMS to recalculate Star Ratings for the plan, which resulted in CMS recalculating Star Ratings for the entire Medicare Advantage industry.
- Represented a Medicare Advantage organization in a challenge to the 2025 Star Ratings due to CMS’s improper treatment of a single telephone call in calculating Star Ratings, which created a substantial financial impact to the plan in lost quality bonus payments. This matter was resolved and the plan voluntarily dismissed the lawsuit.
- Represented a Fortune 500 managed care organization in lawsuit brought by a long-term care pharmacy over reimbursements relating to co-payments under Medicare Part D.

- Represented Medicare advantage organization in qui tam lawsuit alleging false claims liability by Part D plans in connection with direct and indirect remuneration. The government ultimately dismissed the proceedings under its statutory dismissal authority.
