Because of the redirect to Healthcare.gov, the number of errors that can pause applications is much lower. However, one common error is a mismatch between quoted county and the client’s actual, physical county.
For example, let’s say a zip code has 2 counties: Smith County & Jones County. The client’s physical address is in "Smith County", but the plan selected was for "Jones County".
This may pause an application because the plan selected is unavailable in the actual physical county. These types of applications cannot be submitted. The client needs to fill out a new application with the plan from the actual county.
