Medicare Advantage & Part D Actuarial Services
Lewis & Ellis (L&E) provides end-to-end actuarial and strategic consulting for Medicare Advantage and Part D organizations. With decades of experience working alongside CMS and Medicare organizations of all sizes, we help plans navigate regulatory complexity, manage risk, and make informed decisions in an increasingly volatile Medicare environment.
Our work goes beyond bid completion. We partner with leadership teams to bring clarity, independent perspective, and practical strategy to pricing, benefit design, pharmacy, and long-term Medicare performance.
Medicare Bid Development & Certification
L&E has supported Medicare bid development since the earliest years of the CMS desk review process and has certified Medicare Advantage and Part D bids for more than a decade.
Our services include:
- Full Medicare Advantage and Part D bid development
- Completion of CMS Bid Pricing Tools (BPTs)
- Completion of CMS Plan Benefits Package (PBPs)
- Bid certification and actuarial support
- Documentation and CMS submission support
- Iterative pricing rounds with clear summaries of changes and impacts
We combine technical rigor with practical insight, ensuring bids are compliant, defensible, and aligned with organizational strategy.
Strategic Medicare Consulting (Beyond the Bid)
Many organizations have capable teams and functioning bid processes but seek an independent, senior actuarial perspective to validate assumptions and challenge strategy. L&E provides strategic Medicare consulting as a standalone service or alongside bid development.
This includes:
- Shadow pricing and second-opinion reviews
- Benefit and product strategy assessment
- Market-specific competitive positioning and feasibility analysis
- Scenario testing and sensitivity analysis
- Support for executive and board-level decision making
- PBM contract evaluation and support
- Formulary and benefit design analysis
- Strategic planning for any regulatory or other market-wide changes
Our role is to help leadership teams ask the right questions—and answer them with confidence.
Risk Adjustment & Financial Performance
Accurate risk adjustment remains one of the most critical drivers of Medicare Advantage performance. L&E helps organizations evaluate whether financial results reflect true population risk—and where improvement opportunities exist.
Our services include:
- Risk score development and trend analysis
- Evaluation of documentation, coding, and encounter data impacts
- Financial performance diagnostics
- Support of CMS inquiries and audits related to risk adjustment
We focus on defensibility, sustainability, and alignment between clinical activity and financial outcomes.
