Shell rot appears as black or dark green patches that have eaten away parts of a hermit crab's exoskeleton. It most often occurs on the legs, but may also affect claws and the body. It is unknown whether shell rot can affect humans, but it may spread between hermit crabs. There has not been a lot research conducted on shell rot, but it may affect other crustaceans such as lobsters. Hermit crabs can free themselves from shell rot by moulting.
In CPT 2008, the American Medical Association (AMA) published the total laparoscopic hysterectomy (TLH) set of codes (58570-58573).
Hysterectomy is the surgical removal of the uterus. In a total hysterectomy, the uterus and cervix are removed. In some cases, the fallopian tubes and ovaries are removed along with the uterus (called hysterectomy with bilateral salpingo-oophorectomy). In a subtotal hysterectomy, only the uterus is removed. In a radical hysterectomy, the uterus, cervix, ovaries, oviducts, lymph nodes, and lymph channels are removed. The type of hysterectomy performed depends on the reason for the procedure.
