Broken collarbones are getting the short end of the stick, medically speaking. Since there is little to do for them now (the figure-of-eight brace is falling out of fashion), a lot of ER people shrug and don't make much of them. If I had a piece of bone disfiguring my neckline, I'd certainly want someone to look at it both medically and cosmetically.
You did fine taking your son yourself; he probably got there faster than if you had waited for EMS and very few clavicular fractures get pneumothoraces (punctured lungs).
