There are no codes in the vulvar excision section for a cyst removal (other than Bartholin's) and this cyst was of the labia so that rules out the vaginal cyst excision code of 57135. The code I have settled on is 11423: Excision, benign lesion including margins...genitalia; excised diameter 2.1 to 3.0cm.
A ll modern mollusks have the same fundamental body plan. There are three distinct body zones: a head-foot, a visceral mass and a mantle. Some common features are 1  : Unsegmented soft body with bilateral symmetry.
The three major classes ofmollusks are the gastropods (snails and slugs), the bivalves(oysters and clams), and the cephalopods (octopuses andsquids). While they seem very different at first glance, oncloser inspection, they all have the same basic mollusk bodyplan.
