Long before Cigna paid $3.8 billion for HealthSpring, Herb Fritch spent decades learning how insurance risk, physician incentives and patient care fit together.
In the modern era of Koi few people stand out in the way Herb Fritch does. Evolving from a simple pond at his home with small ‘domestic’ koi into the largest private Koi Farm and Collection in the world takes some doing. The thing you’ll find with Mr. Fritch is that he doesn’t do things halfway. When his interest in something engages his passion.… he goes all in.
The purpose of this long form story is to share the reality of how the Myth that is Herb Fritch in the Koi World came to be in a position to build the World’s largest Private Koi Farm and award winning Koi Collection. Following this part one will be part two, the Aviary and herd animals including Watusi Cattle, Red Deer, Elk and Buffalo on his Tennessee property. The final, part three, will be about the koi farm and his collection of award winning Nishikigoi.
I was lucky to speak to Mr. Fritch about his work as an Actuary that led him into the world of Health Insurance. It’s this work that saw his personal fortune grow beyond that of a son to a railway brakeman from Duluth, Minnesota.
Sitting at home in the middle of COVID lock down is how a man who has been involved in Conservation Ranching and Aviculture took the serious leap into Koi. “During COVID, it was just one night I was sitting around and I decided to Google Jumbo Koi., and I got about six dealers, and I ended up buying from VJ down in Atlanta.” (Vijay at Grand Koi, Douglasville, GA)
Let the story begin
Herb Fritch and the Long Measure

The story of Herb Fritch HealthSpring does not begin with $3.8 billion.
It begins with mathematics.
Before Herb Fritch became a founder, chairman, chief executive and major shareholder, he was an actuary. The early work was quiet and exact: study risk, test assumptions and decide whether promises made today could still be kept when the medical bills arrived years later.
In health care, an actuarial table is never only a table. Behind it are patients, chronic illness, physician judgment, hospital stays and the question that follows every health plan: who carries the risk?
Fritch spent nearly four decades learning each side of that question.
The Actuary’s Foundation
Herbert A. Fritch was born and raised in Duluth, Minnesota. He studied mathematics at Carleton College and began his career in 1973 as a consulting actuary with Milliman & Robertson.
His work there included analyzing the feasibility of health maintenance organizations, or HMOs. He later became a Fellow of the Society of Actuaries and a member of the actuarial profession’s national academy.
An actuary measures uncertainty.
For a health plan, that means looking ahead. How many members will need care? What illnesses will appear? How often will people visit a doctor or enter a hospital? Will the premiums collected be enough to pay the claims, maintain the required reserves and keep the promise made to the patient?
The calculations matter, but the organization behind them matters just as much.
A model may be sound on paper. It must still work in the offices of physicians, in hospital corridors and across thousands of individual decisions about care.
That practical side of the work would gradually draw Fritch away from consulting and into operations.
Learning to Operate
In 1982, Fritch founded Sanus Corporation, a regional managed-care company. Sanus became a place where he experimented with financial incentives and new ways of working with physicians to improve the delivery of care.
From 1988 through 1991, he served as a regional vice president for Partners National Healthplans, overseeing seven HMOs across the southern United States.
A consultant can identify risk.
An operator must live with the result.
At Partners, the numbers were no longer only projections prepared for someone else. Fritch was responsible for health plans already in motion, with members to serve, doctors to pay and regulators to satisfy.
He was learning the insurance side from the inside.
The next part of the road brought him closer to the doctors.
The Physician Side of Managed Care
In 1991, Fritch founded North American Medical Management, commonly known as NAMM. It was an independent physician association management company, and he served as its president through 1999.
PhyCor, a physician-practice management company, acquired NAMM in 1995. After the acquisition, Fritch also served as PhyCor’s vice president of managed care.
An independent physician association occupies a place between the individual doctor and the large health plan.
The physicians remain independent, but they organize around common contracts, networks, information and systems of accountability. The work requires an understanding of what health plans need, but it also requires respect for how doctors actually practice medicine.
By the end of the 1990s, Fritch had seen managed care from several directions.
He had studied HMOs as an actuary. He had founded a regional managed-care company. He had overseen health plans across the South. He had built and managed an organization serving independent physicians.
Those years became the preparation for HealthSpring.
A Troubled HMO in Nashville
The opportunity arrived in Nashville in September 2000.
Through NewQuest, the predecessor organization led by Fritch, an investor group purchased a 50 percent interest in an unprofitable Nashville-area HMO. The plan had approximately 8,000 Medicare Advantage members in five counties and about 22,000 commercial members in 27 counties.
This was not the purchase of a polished company ready for expansion.
It was a troubled plan.
Carleton College’s later account says many health plans were withdrawing from Medicare at the time and that few investors shared Fritch’s confidence in the market. To help assemble the capital, Fritch personally carried 15 percent of the original funding.
The business that became HealthSpring was built from there.
The company reported that it restored the Nashville HMO to profitability in 2001. NewQuest acquired an additional 35 percent interest in 2003 and the remaining 15 percent in March 2005. The growth was substantial.
From approximately 8,000 Medicare members in five Tennessee counties in late 2000, HealthSpring reached more than 100,200 Medicare Advantage members in 105 counties across five states by the end of 2005.
HealthSpring did not begin with a clean sheet of paper.
It began with an old plan that had to be repaired.
That distinction matters. Fritch’s work was not simply to imagine a better health plan. It was to make an existing one function again.
When Ownership Changed Shape
HealthSpring was never a one-man holding company.
Fritch was its founder, operating leader and an important shareholder, but ownership was shared among employees, directors, outside investors and, later, private-equity and public shareholders.
As the company grew, the ownership structure changed.
A recapitalization completed in March 2005 brought in GTCR and other investors. SEC filings valued the overall recapitalization at approximately $438.8 million. Afterward, GTCR funds owned 55.1 percent of HealthSpring, executives and employees owned 28.7 percent, and outside investors owned 16.2 percent.
The transaction was also Fritch’s first clearly documented major liquidity event at HealthSpring.
An SEC table shows that he sold 403,176 NewQuest membership units carrying a cash value of $32,104,404. He exchanged additional units for 4,077,139 HealthSpring common shares and 30,420 preferred shares, preserving a substantial interest in the company he continued to lead.
The structure had changed, but Fritch remained at the center of the operating business.
HealthSpring went public in February 2006. Its initial offering was priced at $19.50 per share, with 18.8 million shares offered and a total offering value of $366.6 million. The company sold 10.6 million new shares, while GTCR sold 8.2 million existing shares. No other shareholder sold stock in that initial offering.
At the time of the IPO, SEC filings listed Fritch as the beneficial owner of approximately 5.76 million shares, representing about 10.1 percent of the company after the offering. Some of those shares were held in trusts for his children and stepchildren.
Fritch was no longer an owner in the small-company sense.
He was the founder and chief executive of a public corporation, responsible to a board, regulators and thousands of shareholders.
He had taken some money off the table.
He had also kept a large stake in what came next.
Building Around Physicians
HealthSpring’s public filings reveal how much of Fritch’s earlier career had been carried into the company.
The plan did not treat its physician network as a simple list of contracted providers. HealthSpring described strong provider relationships as essential to membership growth, quality and cost control.
Its reimbursement arrangements included fee-for-service payments, capitation and risk-sharing agreements with physician groups. Its “partnership-for-quality” program offered financial incentives to medical practices that met clinical-improvement goals. The company also placed support inside practices, including information-technology assistance and an in-office coordinator, usually a nurse dedicated to HealthSpring members.
HealthSpring used case-management programs for patients with chronic conditions, coordinated transitions between hospitals and outpatient care, and worked to reduce duplication in fragmented health systems. Its LivingWell centers brought physicians, nurse practitioners, nurses, pharmacists and nurse educators into a more coordinated care setting.
These programs were not separate from the business model.
They were the business model.
The insurer carried the financial risk. The physician carried the clinical responsibility. HealthSpring tried to place both sides inside the same system of information, incentives and accountability.
It was an operating translation of lessons Fritch had been gathering since his actuarial years.
From Regional Plan to National Scale
By December 31, 2010, HealthSpring operated Medicare Advantage plans in 11 states and the District of Columbia. It also offered regional and national stand-alone Medicare prescription-drug plans and continued to provide management services to independent physician associations.
The company ended 2010 with 304,604 Medicare Advantage members and 724,394 stand-alone prescription-drug members. Medicare premium revenue reached approximately $3.1 billion, and net income rose to $194.2 million.
HealthSpring was also becoming an acquirer.
In November 2010, it purchased Bravo Health for approximately $545 million in cash. Bravo brought more than 105,000 Medicare Advantage members and approximately 301,000 prescription-drug-plan members into the company.
The small Nashville HMO was gone.
In its place stood a large Medicare company with operations extending across much of the country, a broad physician network and a business generating billions of dollars in annual premium revenue.
That scale drew the attention of Cigna.
The Sale Begins Quietly
The final chapter began with a conversation.
On May 19, 2011, Cigna chief executive David Cordani met Fritch in Nashville and expressed interest in exploring a combination of the two companies. HealthSpring’s board authorized preliminary discussions, and other potential buyers eventually entered the process.
The sale was not automatic, and the highest price did not win.
During the final negotiations, an unnamed competing bidder raised its proposal to $56 per share. Cigna was offering $55. HealthSpring’s board concluded that the competing proposal carried greater antitrust and closing risk and that Cigna’s slightly lower offer provided greater certainty.
The board chose Cigna.
It was a decision built around both value and risk.
On October 24, 2011, Cigna and HealthSpring announced an agreement at $55 per share in cash. The price represented a 37 percent premium over HealthSpring’s previous closing price and placed the total transaction value at approximately $3.8 billion. Cigna said Fritch and HealthSpring’s leadership team would lead its expansion in the senior and Medicare markets.
At the time, HealthSpring had approximately 340,000 Medicare Advantage members and more than 800,000 prescription-drug-plan customers. Reuters reported that Cigna had only about 46,000 Medicare Advantage members of its own, making the purchase an immediate and significant expansion into the Medicare business.
Cigna was not only buying membership.
It was buying a physician-engagement model, an experienced Medicare operation and a management team that had spent years learning how to join actuarial risk with the daily work of medical care.
The transaction closed on January 31, 2012. Each qualifying outstanding HealthSpring common share was converted into the right to receive $55 in cash, and HealthSpring became an indirect, wholly owned Cigna subsidiary.
The Long Measure
The sale was the last number on a long page.
From 1973 to 2011, Fritch moved from calculating whether HMOs could work, to operating them, to managing physician organizations, to rebuilding a troubled health plan and finally to leading a public company.
The line through those years was not simply insurance.
It was the relationship between the organization carrying the financial risk and the physician carrying responsibility for the patient.
From a distance, the ending looked sudden: $55 a share, a 37 percent premium and a $3.8 billion transaction. Up close, it was 38 years of accumulated work.
The actuary became an operator.
The operator learned the physician’s side.
The physician-group manager returned to the health plan with a clearer idea of how the parts might be joined.
That was HealthSpring’s foundation.
The sale was only the final measure.
