Please note that although Primecare is indeed set up to treat many situations that might otherwise necessitate a trip to the Emergency Room, it is not, in fact, the destination of choice when you have severed part of a digit and are clutching it to the remaining finger stump, your entire hand and lower arm swaddled in a plastic bag.
In that situation, you really should go directly to the ER.
PS: Not me. Nor one of mine.
PPS: I cannot believe the man was even standing upright.
