Hawaii Pacific Health, HMSA discussing possible merger
Some major changes are potentially afoot for Hawaii’s health care market in the face of labor demands and rising costs.
Two of Hawaii’s largest players,
The two confirmed they have been in talks about joining forces, with the goal of addressing affordability, expanding access, and improving long-term financial stability.
“HPH recognizes that affordability is becoming increasingly out of reach for families across the nation, and in

Growing mergers Nationally, health care mergers and acquisitions have been a growing trend for the past 30 years, according to KFF, a nonprofit health policy think tank.
An increasing share of community hospitals are affiliated with larger health systems, and an increasing share of physicians are also affiliated with hospitals or health systems, KFF said.
There have been both horizontal mergers—a consolidation between entities offering same or similar services—and vertical mergers—a consolidation between entities offering different services along the same supply chain.
Vertical mergers include a growing number of health systems, for instance, acquiring physician practices. Another example is
There are several possible scenarios for the vertical merger of HPH and HMSA, according to
There could be better coordination of care, cost savings from economies of scale, and more financial stability. Those cost savings could either be held onto as a profit, reinvested into technology or the hiring of more nurses—or be passed along to members as lower premium growths.
That would depend on Hawaii’s market and regulations, he said, and there’s not enough empirical evidence on hospital-insurer mergers to predict the impact on premiums or out-of-pocket spending.
At the same time, Godwin said, there have been a growing number of hospital-insurer disputes, some leading to very public battles. A health care system and insurer uniting under the same umbrella could find ways to economize and avoid this tension, he said.
But consolidation also could mean reduced competition, a better bargaining position for the newly consolidated entity that could then seek higher premiums, and fewer choices for patients.
“One of the outcomes of consolidation is, generally, there are fewer choices for patients, ” he said.
Consolidation also could lead to fewer employment options for physicians, nurses and health care workers, and that could reduce wage growth over time.
Additionally, “With a vertically integrated arrangement, all of a sudden you’re thinking about it from the perspective of the insurer. The insurer wants to pay less per given service. They want to save money.”
There could also be a competitive disadvantage for other players in the market. One potential scenario is that HMSA-covered patients can be treated at an HPH hospital for a lower co-pay or shorter wait time, and certain hospitals could get more referrals than others.
Vertical mergers have not been regulated much, to date.
“This is kind of an area in regulation and antitrust that is not as well developed as horizontal mergers, ” said Godwin. “With vertical mergers there’s less precedent for regulators to intervene.”
Last year, Kaiser’s new nonprofit arm,
It was part of Kaiser’s strategy to acquire “like-minded, nonprofit, value-oriented community-based health systems ” in order to manage costs through shared infrastructure. The two acquisitions have boosted Kaiser’s financials, according to a “Health-Leaders ” analysis, bringing in a net income of
Unique market share
It offers a full spectrum of care, from primary and urgent care to complex specialties through more than 70 locations, including urgent care centers and clinics across the state.
HPH also operates Kapi ‘olani, the only specialty hospital for women and children in the state, with 24-hour emergency pediatric care and high-risk perinatal care and
HMSA, founded in 1938, covers more than half of the state’s population of about 1.4 million. It has more than 760, 000 members, and offers a diverse number of plans for individuals, families, and employers from a large network of providers.
HMSA has faced a number of lawsuits in recent years—from ones questioning its status as a nonprofit provider to others challenging its contract terms and prior authorization processes. But it remains Hawaii’s largest and most experienced insurance provider.
Shared goals Ultimately, HPH said its shared goal with HMSA is “to improve care delivery, elevate the patient experience, expand access, and ensure long-term financial sustainability.”
“We are grounded in a commitment to an open system where individuals have the freedom to choose the health insurance they trust and receive care from the providers and medical facilities they prefer, ” said HPH in a statement. “This effort is not about any one system or organization—it’s about building a resilient, inclusive health care ecosystem that serves our entire community. While these discussions are preliminary, they are urgently needed. Together, we are laying the foundation for healthier communities – for generations to come.”
Other health systems, including
“The well-being of Hawaii’s people will always remain our highest priority, and we stand with the health care community in supporting innovations and partnerships that help our communities thrive, ” said Kaiser in a statement. “We will continue to monitor developments and welcome the opportunity to engage in further dialogue as more details emerge.”
Kaiser said it has proudly served the people of

“With that at our core, we know that any news about a possible merger that could alter the ability of individuals and families to continue receiving primary and specialty care from their trusted providers will be of great concern to our community, ” said Queen’s in a statement. “Hawaii already has a concentrated health care market, and a major structural change could significantly reduce competition in both insurance and care delivery, and negatively impact patient access, consumer choice and cost of care, especially for vulnerable populations.”
Queen’s continued with, “We will continue to share our concerns on this possible merger as more details become available. For Queen’s, the health and well-being of Hawaii’s people will always remain the highest priority, and we support practical, collaborative solutions that don’t require consolidation of this scale.”
