(at least I like to think so)

Spoiler:

I think there's a panel or two in the manga that shows Genma splattered bloody against a wall, but later on he turns up alive and well on a mission with Shizune, so I presume he healed pretty fast. Right now he's idling away his time in the hospital with his good buddy Raidou after having gotten his @$$ handed to him by 4 pesky kids.
