There are several separate issues and decisions here.
All breast implants heal with a layer of scar tissue around them which is called a capsule. Capsules can be normal or abnormal just like scars. If a capsule or scar is removed then a new scar will form. There is no reason or advantage to doing this if the capsule or scar is normal.
Removing implants is one decision. In general, there is no reason to remove the capsule around the implant just because it's there as a new layer of scar will form and the removal of the capsule (capsulectomy) is more involved, expensive, and has more risks of problems. Capsulotomy means putting cuts in the capsule to reshape it and there is no reason to do this either if the capsule is normal and the implant is removed.
If the capsule is abnormal due to thickness, calcium deposit, silicone permeation or something suspicious, then partial or even complete capsulectomy might be needed. Generally this is still considered a cosmetic procedure and unless there is breast cancer involved, is not something to expect insurance to cover.
