Related: CMS announces another round of ACA navigator funding cuts

When asked in May about the removal of an ACA reference, the Washington Post was given this response by a CMS representative: “CMS performs routine updates and maintenance to our websites, which includes the revision and removal of content that is not current or underutilized. In this instance, there was a period of time when people with Medicare coverage had questions and interest in the ACA and its impact on Medicare. However, the ACA has now been law for over eight years and both HealthCare.gov and www.cms.gov/cciio [cms.gov] are well-established sites for Healthcare Exchange information.”

The removals are consistent with other actions the administration has taken to reduce information about ACA health plans and make it harder for people to enroll.

Last year, the administration reduced the amount of spending on advertising for ACA plans by 90 percent and reduced funding for health care navigators that help people enroll in plans by 41 percent –– from $62.5 million a year to $36.8 million a year.

Earlier this week, the administration announced that it would further reduce funding for navigators by more than two-thirds –– to $10 million a year.

In addition, groups that apply for navigator grants will be expected to also provide information to people they help about non-ACA plans, including short-term plans and association plans, both of which may not cover certain medical services that all ACA plans must offer. Some short-term plans, for instance, may not cover hospital visits.

All of these actions, along with the repeal of the individual mandate and the withholding of cost-sharing reduction payments and risk corridor payments to insurers, contribute to destabilizing the ACA marketplace and driving up premiums for those with ACA plans.
