Disp fx of lesser tuberosity of unsp humer, init for opn fx

This code signifies a break in the lesser tuberosity of the humerus, where the bone fragments are no longer in their normal anatomical alignment. It specifically indicates that the fracture is open, meaning there's a break in the skin and soft tissue communicating with the fracture site, and this is the initial treatment encounter for the injury.

Apply this code when documenting the first treatment for an open fracture of the lesser tuberosity of the humerus, regardless of which arm is affected. This would typically be used in emergency department settings or initial surgical admissions following such a traumatic injury.

• Ensure documentation clearly specifies "open fracture" and "displaced" for accurate code assignment.
• The "unspecified humerus" component means this code is used when the laterality (left or right) is not documented.
• The "initial encounter" character is crucial and should only be used for the period of active treatment for the fracture.
