the procedures that you mentioned are only considered cosmetic if the patient does it because their foot looks weird. If the incision is placed on the medial side of the bunion or medial or lateral side of the toe for a hammer toe it can be considered cosmetic. If it is for pain or cannot fit into shoes it is not considered cosmetic.
Typical cosmetic procedures are:
Restalyne injection into the plantar fat pad (ball of the foot) for comfort w/ high heels or fat pad atrophy.
Botox - stops the sweating
Foot Facials - Suzanne Levine does these

Medipedis - medical pedicure
2nd toe shortening (AKA arthroplasty) so women can fit their feet into pointed shoes better and get better toe cleavage
that is all I can think of for now.
