It is medical ninjutsu, having been called the pinnacle of medical ninjutsu by it’s creator.Mate genesis rebirth isn't medical jutsu and neother does it work/ function on the same mechanics. If you were talking about mystic pals etc then I would agree with you.
The mechanics however are as you claimed different. Each damaged or destroyed cell being recreated instead of healed.
However given the nature of RS and how it is described as countless blades of wind, it’s going to be a problem . Each and every cell is going to have to replace it’s self multiple times over... covering the distance of her entire body, including her head and the seal. Also what is she going to do about the cutting force? The cutting power alone is going to separate her torso from her legs.
