The term **会诊** (huìzhěn) is a compound word formed by combining the character **会** (huì), meaning "to assemble" or "to meet," with the character **诊** (zhěn), meaning "to diagnose" or "to examine." Literally, it describes a "meeting for diagnosis," which accurately reflects its modern medical meaning: a **consultation** or **case conference** where multiple doctors or specialists gather to collectively discuss and diagnose a complex patient condition, thereby pooling their expertise to determine the best course of treatment.
