What does "10-19" specifically refer to in police codes?

This code is part of a larger set of ten-codes, which are designed to enhance clarity and brevity in radio communications among law enforcement officers. When officers communicate that they are "10-19," they are signaling that they have returned to the police station, allowing other officers and dispatchers to know their status and proximity.
