Hip arthritis callers describe groin pain, trouble with shoes and socks, and sleep interrupted by position changes. They route to the joint replacement team, and because hip pain masquerades (back, buttock, knee), good intake notes on pain location save a misrouted first visit.
ClinicFlow's voice AI runs this intake on every call for joint replacement practices: capturing the story, applying your routing rules, and booking the right visit type with the right surgeon. See voice AI for joint replacement practices or the Call Library for how each call type is handled.
