I answered how I woulld do it but I think the game should just do what Mike Mearls suggested in June 2013.

He goes on to list a potential default and then a bunch of options depending on what tables want.

Mike Mearls said:Time and again, we've seen divergent opinions on what hit points represent, how quickly they refresh, and so forth. When we read comments, we see many views that coincide with this concept of genre. Are the characters in your campaign the main characters in a grand story? You want an easy way to get hit points back. Does your campaign embrace the survival of the fittest, with one bad decision leading to ruin? Then you're fine with an extended period of time needed to regain hit points.
D&D as an RPG has developed a few genres within itself. You can see this in how people talk about the game. Some groups run intricate stories that place their characters at the center of world-changing events. Other groups play characters who are merely one adventuring band among many, delving into ruins in search of treasure and risking life and limb to the vagaries of the dice. When you say roleplaying game, do you emphasize roleplaying or game?
There's no right answer here, and that's why we're embracing the idea of hit points as something that DMs can customize.
