For the purpose of cell-assisted fat injection, functional area will be restricted to the head and neck, hands, perineum and groin, as well as in the direct vicinity of major joints. The breast is considered a non-functional area for this indication.
Non-functional areas are defined as: posterior or anterior trunk (including breasts), arm (above elbow), forearm (below elbow), thigh, leg (below knee).
Facial subunits such as eyelid and lip are considered part of one aggregate fee for the face. Injections of multiple subunits of the face are still considered one aggregate area, the face.
Bilaterally symmetrical sites, as in breasts or axillary regions are considered separate areas.
