Anthem insurance, post-op

DH has a chance for a different job, they offer Anthem insurance. I realize it depends on the policy, but am wondering in general...... Does anyone know how good this insurance is? Do you think they'd cover any wls related medical problems that may arise in the future?  Or would they consider it a pre-existing condition? What about excess skin removal? Pannilectomy? At his current job he currently has BCBS Community Blue PPO insurance and it's fantastic! They had no trouble approving and paying for everything! Thanks for the info...........
