Should/Does the plastic surgeon revise for free if I'm unhappy with my results 11 days out? (Photo)

Though it is still early, your concerns will likely persist.  I agree that this is likely a floated belly button tuck.  If so this is very difficult to fix later with a full tummy tuck as the belly button will not survive.  If that happens a new belly button would need to be fashioned.  'Refloating' the belly button will help with the skin laxity, but will move the belly button further down toward your pubis.  Try not to get discouraged, and give it some time.  Much of the laxity may improve.  Good luck and take care. 

Thank you for your pictures. Revision policies for up to the individual surgeon/offices. You need to discuss this policy with your surgeon.  I am sure that you could come to some reasonable middle ground about who would be responsible for fees if they revision is needed. I would give you result three months before you critically judge it.  

Your surgeon is right. It is too soon to consider a revision.  From your photos, I don't know what the current problem is, but you must let things heal further before embarking on a revision.  As far as the cost of a revision, it depends on the surgeon's policy, which may be in the consent form you signed.

Plastic Surgeons have different policies about responsibility for patient outcomes. I can see your concern about the skin around your umbilicus and would be talking to your PS about your concerns and ask him directly what he will have to do to get rid of those wrinkles and loose skin if they do not resolve over time as he suggests. Also mention cost to you. Most PS want all their patients happy and will do things to give them a better result usually at no extra charge if possible. 

With this type of procedure, there will not be much improvement of the skin around your belly button.  However it may have been possible to do a full tummy tuck as it does not look like you had that much skin excess prior to surgery.  I would discuss your concerns with your surgeon.  Each surgeon has different policies regarding revision.
