The company said on Tuesday it was still working with some state regulators on its market participation for next year . Anthem and other insurers have a deadline of Sept. 27 to finalize their 2018 Obamacare roles.
Separately, independent Senator Bernie Sanders, a 2016 Democratic presidential candidate, was pushing a plan to widen the Medicare health insurance program for seniors, to include everyone.
Most Republicans looked askance at the idea, which Sanders has long championed, while some leading Democrats like House Democratic Whip Steny Hoyer said their priority was improving Obamacare.
The Republican anti-Obamacare campaign was not entirely over. Two Republicans were planning to announce a new repeal-and-replace proposal on Wednesday that has White House support.
Senators Lindsey Graham and Bill Cassidy will offer legislation to give states money in the form of block grants instead of the federal funding states get under Obamacare.
Critics said the approach would effectively cut billions of dollars in funding for Obamacare subsidies and for the Medicaid program for the poor that many states expanded under Obamacare.

"It would take an extraordinary lift to get that done before the deadline," said Senator John Thune, a member of the Republican leadership.
