In Medicare, Less Is Now More for Big Insurers

The era of aggressive growth at all costs in Medicare Advantage appears to be waning for some of the biggest players. UnitedHealth Group and CVS Health, through its Aetna subsidiary, are embarking on a strategic pivot, consciously pruning their MA plan portfolios. Their new mantra? Profitability over sheer market share.
This isn't a minor adjustment; it's a significant strategic shift that underscores a maturing and increasingly competitive Medicare Advantage market. For years, insurers chased member growth, often expanding into new counties and offering generous supplemental benefits to attract seniors. Now, the focus has narrowed considerably to maintaining strong margins in a landscape complicated by rising medical costs and tighter regulatory pressure.
UnitedHealth Group (UnitedHealth Group), the nation's largest insurer and a dominant force in Medicare Advantage, recently signaled its intent to reduce its MA offerings for the 2025 plan year. While precise numbers won't be fully public until plan filings are complete, the company has indicated a deliberate move away from plans with lower Star Ratings or those operating in highly competitive, less profitable geographies. This recalibration is a direct response to the escalating cost of care, particularly post-pandemic, which has squeezed margins across the industry. UnitedHealth's goal is clear: optimize its portfolio to ensure each plan contributes meaningfully to the bottom line, even if it means sacrificing some enrollment volume.
Not to be outdone, CVS Health's Aetna unit is also tightening its belt. Aetna has been notably aggressive in pulling back from certain markets where its plans were underperforming or proving too expensive to operate profitably. This has reportedly impacted hundreds of thousands of members, who will need to seek new coverage or switch plans in the upcoming annual enrollment period. The company's strategy emphasizes focusing resources on areas where it can maintain strong margins and deliver a high-quality experience, rather than spreading itself thin across less viable markets. This includes exiting plans that consistently fail to achieve a 4-star rating or higher from the Centers for Medicare & Medicaid Services (CMS).
This strategic retreat isn't happening in a vacuum. Insurers are grappling with a cocktail of financial headwinds. Rising medical costs, driven by higher utilization rates—especially for services like outpatient care and specialty drugs—are eating into profits. Many plans also face pressure from the Medical Loss Ratio (MLR) requirements, which mandate that a certain percentage of premiums be spent on clinical services and quality improvement. What's more, the CMS Star Ratings program, which directly impacts government reimbursement rates, has become increasingly stringent. Plans with lower ratings receive less federal funding, making them less profitable and, consequently, targets for reduction or elimination.
For beneficiaries, this shift could mean fewer choices in some counties, potentially higher out-of-pocket costs, or a need to re-evaluate their current plans more carefully during the annual enrollment period. While the overall MA market remains robust and competitive, the strategic pruning by these giants suggests a more disciplined approach to growth that prioritizes financial sustainability.
Historically, Medicare Advantage has been a goldmine for insurers, offering consistent growth and attractive margins compared to other health insurance segments. However, the landscape is evolving. Analysts suggest that the era of easy profits might be giving way to one requiring more precise execution and a willingness to walk away from unprofitable ventures. This move by UnitedHealth and CVS indicates a broader industry trend where scale alone is no longer the primary driver of value.
The message from the industry's titans is clear: in Medicare Advantage, a leaner, more focused approach is now perceived as the path to sustainable success.
