If you enrolled in your policy on or before March 23, 2010, your policy maybe grandfathered. Your agent or customer service representative is the best source for specific information about whether your policy is grandfathered. Please consult them if you are considering changes to your policy since any grandfathered status might be affected by policy changes.
If you enrolled in your policy after March 23, 2010, you do not have a grandfathered policy.
