CMS Proposes Curbs on Medicare Advantage Chart Reviews to Combat Overcharges Impacting Hospital Partnerships

29 January 2026

The Centers for Medicare & Medicaid Services (CMS) has unveiled a pivotal proposal on January 29, 2026, aiming to impose strict curbs on Medicare Advantage (MA) insurers' chart review practices, which have long been accused of generating billions in overpayments. This move, part of a broader plan to maintain flat reimbursement rates for 2027, represents a significant shift in federal policy under the Trump administration, directly influencing hospital management strategies, payer negotiations, and financial planning across U.S. healthcare facilities.

Medicare Advantage, enrolling over 34 million beneficiaries or more than half of eligible Medicare recipients, has faced scrutiny for upcoding—exaggerating patient diagnoses via chart reviews without corresponding treatments. Government auditors, including a 2019 Department of Health and Human Services inspector general report, highlighted that over 99% of chart reviews added diagnoses, leading to an estimated $6.7 billion in improper 2017 payments alone. The new proposal seeks to eliminate payments for diagnoses identified solely through chart reviews, ensuring funds align with actual health needs and protecting taxpayer dollars.

For hospital administrators and clinical leadership, this development is strategically critical. Many hospitals partner with MA plans for patient care, and overcharges have indirectly inflated operational costs through misaligned reimbursements. CMS Administrator Mehmet Oz emphasized that these policies will enhance payment accuracy, stating, 'These proposed payment policies are about making sure Medicare Advantage works better for the people it serves.' Experts like Spencer Perlman, a Bethesda-based health policy analyst, note the administration's seriousness in addressing undue profits, potentially stabilizing hospital budgets strained by payer mix shifts.

The announcement triggered immediate industry backlash. Major insurers like UnitedHealth Group and Humana experienced stock plunges, while AHIP warned of potential benefit cuts and higher costs for 35 million seniors by October 2026. However, analysts such as David Meyers from Brown University argue that plans remain profitable, rarely slashing benefits despite complaints. This tension underscores the need for healthcare facility managers to reassess contracts, monitor regulatory updates, and prepare for phased implementation if finalized by early April after public comments.

Historical context reveals repeated CMS attempts to rein in these practices, such as a 2014 proposal abandoned amid industry uproar. Recent events, including a $556 million Justice Department settlement with Kaiser Permanente over $1 billion in alleged improper payments from 2009-2018, bolster the case for reform. Richard Kronick, a UC-San Diego professor, views it as a 'mildly encouraging sign,' though he cautions plans may adapt. For procurement professionals and medical technology vendors, this could accelerate adoption of compliant documentation tools in healthcare information technology and diagnostics categories.

Hospitals must navigate this within **Healthcare Management** and **Facilities Management** frameworks. Leadership moves, like those at major systems, will prioritize revenue cycle optimization amid low reimbursements. The proposal aligns with broader Trump-era priorities, including support for MA growth while curbing inefficiencies, impacting orthopaedics, oncology, and critical care reimbursements where upcoding is prevalent. Telemedicine and patient monitoring integrations may see boosted scrutiny for accurate coding.

Infection control and pharmaceuticals leaders should note ripple effects on 340B programs and drug pricing, as MA overpayments have subsidized unneeded services. Nephrology, cardiology, and surgical equipment vendors face reevaluation of supply chain partnerships tied to MA volumes. The flat 0.09% rate increase—far below expectations—forces strategic investments in efficiency, echoing Kaufman Hall reports on financial stress.

As public comments unfold, hospital executives are urged to engage, influencing final rules. This policy could save billions, reallocating resources to frontline care in emergency care, radiology, and rehabilitation. For B2B stakeholders, it signals a era of precision in **Healthcare Information Technology** deployments for audit-proof records, ensuring compliance in an evolving regulatory landscape.

Ultimately, this proposal fortifies hospital operations against fiscal volatility, promoting sustainable models in **Oncology**, **Respiratory Care**, and beyond. Decision-makers must integrate these changes into 2027 planning, fostering resilience in American healthcare infrastructure.
