Nondisp fx of triquetrum bone, unsp wrist, init for opn fx

This code signifies a break in the triquetrum bone, one of the carpal bones in the wrist, that has not shifted out of its normal anatomical position. The injury affects an unspecified wrist and is an open fracture, meaning the skin and soft tissue are compromised, exposing the bone. This code is used for the initial treatment of such an injury.

Apply this code when documenting the first encounter for a patient presenting with an open, nondisplaced fracture of the triquetrum bone, where the specific wrist (left or right) is not documented. This is appropriate for the initial surgical repair or emergency department visit for this type of injury.

• Ensure documentation clearly states "nondisplaced" and "open fracture" for the triquetrum.
• Do not use this code if the specific wrist (left or right) is identified; a more specific code exists.
• This "B" extension indicates an initial encounter for an open fracture; subsequent care would use different seventh characters.
