I can say with certainty, when GR left
GA in 2006 it was because the DOI wanted new verbiage and a filed policy (vs. association) in place.
They have left other states (LA for example) due to similar situations.
In
GA they were gone for about 8 months. While not actively writing business, they continued to service and renew existing policies.
In LA it was different. The DOI would not allow them to renew in force policies. They refiled the same policy under UHC and it was accepted by the DOI. Existing GR policies aged off at renewal.
