Some people removed from Affordable Care Act health coverage have been reinstated, Julie Appleby reported for KFF Health News on October 16. The report did not establish how many people had regained coverage, leaving a central question unanswered: how many legitimate enrollees were caught in the cancellation process?

The cancellations themselves were earlier. In a September 22 fact sheet, the Centers for Medicare & Medicaid Services said it had canceled about 315,000 enrollments covering more than 760,000 people on August 31 after determining that they were unauthorized. The number of enrollments and the number of people are different measures because one enrollment can cover more than one person.

CMS’s characterization explains why the agency acted. It should not be treated as an individual finding that everyone whose coverage ended committed fraud. The later reinstatements also do not establish that every cancellation was wrong.

Check whether coverage is active

HealthCare.gov says people unsure about their enrollment should sign into their Marketplace account, open their completed application and select “My Plans & Programs.” That section identifies the plan and its start date. If the information is missing or unclear, the insurer can confirm enrollment and any required first-premium payment. The Marketplace Call Center is the next official route if problems remain.

A request for a review is different from confirmation that insurance is active. Before relying on a plan, a consumer needs the insurer or Marketplace to clarify the actual status.

Use the right route for a dispute

HealthCare.gov distinguishes appeals of Marketplace eligibility decisions from disputes with an insurance company. Its guidance says an insurer’s refusal to pay a claim or decision to end coverage is handled through the plan’s appeal process. It also lists decisions that cannot be challenged through a Marketplace appeal, including disagreement with the date the Marketplace ended coverage.

That distinction matters for anyone trying to correct a problem: read the notice, identify which organization made the decision and follow the applicable official instructions. This reporting does not establish a new reinstatement total or promise that an individual request will restore coverage.
