Healthcare Costs Are on Track for a 17-Year High in 2027
The American healthcare system is approaching a critical inflection point. According to a recent report from PwC, the commercial healthcare cost trend is projected to reach 9% in 2027 — the highest rate seen in nearly two decades. For health plans, employers, providers, and patients alike, this is not an abstract statistic. It represents a looming affordability crisis that threatens access to coverage and care across every segment of the healthcare market.
The challenge, as PwC frames it, is no longer simply identifying what is driving costs higher. The real question is whether health plans can deploy cost-of-care strategies quickly and effectively enough to slow this trajectory before affordability, coverage, and access come under even greater strain. With the clock ticking, understanding the forces behind this surge is the essential first step.
Five Key Drivers Pushing Healthcare Costs to a Breaking Point
PwC's report identifies five converging forces that are reshaping the cost landscape for commercial health plans. Each one is significant on its own. Together, they create a powerful upward pressure on medical spending that will be difficult to counteract without deliberate, well-coordinated action.
1. AI-Enabled Tools Are Helping Providers Capture More Revenue
Artificial intelligence is transforming clinical documentation and medical coding. While these tools can improve accuracy and efficiency, they are also enabling providers to capture revenue at higher rates than before. As AI-assisted documentation becomes more widespread, health plans are seeing increased paid amounts per claim and greater variation in coding intensity across providers. This makes it harder for payers to predict costs and easier for providers to justify higher reimbursements — often without a corresponding improvement in patient outcomes.
2. Inflation and Provider Consolidation Are Driving Up Reimbursement Rates
General economic inflation has rippled through every sector, and healthcare is no exception. Labor costs, supply chain pressures, and overhead expenses have all climbed, pushing providers to negotiate higher reimbursement rates with payers. Compounding this is an accelerating wave of provider consolidation. As hospital systems and physician groups grow larger through mergers and acquisitions, they gain greater leverage in contract negotiations, often securing rates that outpace inflation and leave health plans with fewer competitive alternatives.
3. Pharmacy Costs Continue to Climb
Pharmacy spending remains one of the fastest-growing components of the overall healthcare cost trend. The expansion of high-cost specialty drugs, the rapid adoption of GLP-1 medications for obesity and diabetes, and ongoing brand-name drug price increases are all contributing to a pharmacy cost environment that shows little sign of stabilizing. As more patients are prescribed these therapies and as pharmaceutical manufacturers continue to introduce premium-priced treatments, pharmacy expenditures will remain a significant driver of the 2027 cost surge.
4. Behavioral Health Utilization Continues to Grow
Demand for mental health and substance use disorder services has expanded dramatically in the wake of the COVID-19 pandemic, and utilization has not returned to pre-pandemic levels. Increased awareness, reduced stigma, expanded telehealth access, and growing recognition of behavioral health's connection to overall health outcomes have all contributed to sustained growth in this category. While access to behavioral health care is a positive development for patients, it represents an additional and significant cost pressure for health plans managing a population with escalating mental health needs.
5. The No Surprises Act Arbitration Process Is Adding New Out-of-Network Costs
The No Surprises Act was designed to protect patients from unexpected out-of-network medical bills. However, the independent dispute resolution process established by the law has created an unintended consequence for health plans. Providers have increasingly used the arbitration mechanism to secure out-of-network reimbursements that exceed what plans anticipated. This process has become a new and growing source of upward cost pressure, as providers learn to navigate and leverage the system to their financial advantage.
What Health Plans Must Do Now: PwC's Five Cost-of-Care Recommendations
Facing this convergence of cost drivers, PwC urges health plans not to wait for market forces to self-correct. The report outlines five priority actions that payers should pursue to manage costs proactively and protect the sustainability of coverage.
Start with Payment Integrity
As AI-enabled documentation tools make it easier for providers to code claims at higher intensity levels, health plans must respond with equally sophisticated oversight. PwC recommends that payers assess high-dollar claims before payment is made, track provider-level severity drift over time, and integrate contract terms, payment policy, and claims edits into a single, unified accuracy engine. The goal, the report emphasizes, should be reducing inaccurate payments — not simply issuing more claim denials, which can harm provider relationships and patient access to care.
Manage Utilization More Strategically
Health plans need to take a more proactive approach to utilization management, particularly for high-cost services, specialty drugs, and behavioral health. This means investing in data analytics to identify patterns of overutilization, working with providers to promote evidence-based care pathways, and ensuring that care management programs are targeted at the members who will benefit most. Simply applying blanket restrictions is no longer sufficient in an environment where cost pressures are this complex.
Strengthen Network Design and Contracting
Provider consolidation is giving health systems more negotiating power, but health plans are not without options. Building narrow or tiered networks that direct members toward higher-value providers, renegotiating contracts with a sharper focus on total cost of care, and exploring alternative payment models that align provider incentives with efficiency are all strategies that can help offset reimbursement rate increases.
Expand Pharmacy Management Capabilities
Given the outsized role pharmacy costs play in the projected 2027 surge, health plans must invest in robust pharmaceutical management. This includes working with pharmacy benefit managers to optimize formulary design, promoting biosimilar adoption where available, and developing clinical criteria for high-cost drug approvals that balance patient need with cost stewardship.
Invest in Behavioral Health Infrastructure
Rather than treating behavioral health utilization growth purely as a cost problem, forward-thinking health plans will invest in building integrated behavioral health networks, expanding telehealth capacity, and connecting mental health care to primary care settings. Early intervention and integrated care models can reduce downstream costs while improving outcomes for members.
The Bottom Line: Urgency Is Not Optional
A projected 9% commercial healthcare cost trend in 2027 is not simply a headline for health plan finance teams — it is a signal that the entire healthcare ecosystem must respond with speed and strategic clarity. For employers, it means preparing for higher premium contributions. For patients, it means a growing risk to affordability and access. And for health plans, it means the window to act before costs become unmanageable is narrowing quickly.
The forces driving this trend — from AI-enabled revenue capture to pharmacy inflation to behavioral health demand — are not going away on their own. Health plans that invest now in payment integrity, smarter utilization management, and stronger network strategies will be best positioned to protect both their financial stability and the members who depend on them for affordable, accessible care.
