The official said that at that meeting, administration officials "underscored the importance of continuing the work that has helped bring the uninsured rate to the lowest level on record and solicited ideas for how to strengthen the marketplace."
The president also sent a letter to every insurance company offering coverage in Obamacare plans next year "to emphasize the Administration's commitment to working with them, discuss recent actions to further strengthen the [Obamacare] marketplace, and ask for their help in signing up uninsured Americans," according to the official.
Obama's direct outreach comes as his signature health-care reform law has run into headwinds this year, even as Obamacare has been credited with pushing down the nation's uninsured rate to just 8.6 percent, the first time in history it has fallen below 9 percent.
A trio of major insurers — Aetna, UnitedHealthcare, and Humana — all have said they are sharply pulling back their footprint in the individual health plan market and on the types of plans sold on government-run Obamacare exchanges, which will reduce the number of options available to consumers.
And the premiums on Obamacare plans are set to rise at a greater rate, on average, for 2017, than they have in the past several years.
While Humana CEO Bruce Broussard was at Monday's meeting, the CEOs of Aetna and UnitedHealthcare were not. Other attendees included David Cordani, CEO of Cigna, as well as a number of Blue Cross and Blue Shield plan CEOs.
In addition to Obama, administration officials at the meeting included Sylvia Burwell, the secretary for Health and Human Services, as well as Obama's Senior Advisor Valerie Jarrett, and Deputy Chief of Staff for Implementation Kristie Canegallo.
