Nondisp fx of neck of 4th MC bone, l hand, init for opn fx

This code signifies a break in the neck of the fourth metacarpal bone in the left hand, where the bone fragments remain in their normal alignment. It specifically indicates an open fracture, meaning the skin and soft tissue were compromised, exposing the bone to the outside environment. This is the initial encounter for treatment of this injury.

This code is appropriate for documenting the initial treatment of a patient presenting with a left-hand injury where imaging confirms a nondisplaced fracture of the fourth metacarpal neck. The key is the presence of an open wound communicating with the fracture site, requiring immediate medical attention and management.

• Ensure documentation clearly specifies "nondisplaced" and "open fracture" for accurate code assignment.
• Verify the laterality (left hand) and the specific metacarpal bone (fourth) are explicitly stated in the medical record.
• Confirm this is the initial encounter for treatment; subsequent encounters will require a different seventh character.
