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

This code signifies a break in the neck of the fifth metacarpal bone (the bone connecting the little finger to the wrist) in the left hand. The fracture is "nondisplaced," meaning the bone fragments are still in their normal anatomical alignment, and it is an "open fracture," indicating a break in the skin overlying the fracture site. This code is specifically for the initial treatment of such an injury.

Use this code when documenting the initial encounter for a patient presenting with a nondisplaced fracture of the fifth metacarpal neck in the left hand, where the fracture has broken through the skin. This typically occurs following direct trauma to the hand, such as a punch, and requires immediate medical attention for wound care and fracture management.

• Ensure documentation clearly specifies "nondisplaced" and "open fracture" for the fifth metacarpal neck of the left hand.
• Verify this is the initial encounter for treatment; subsequent encounters will require a different seventh character.
• Always code associated open wound infections or complications separately.
