2-part nondisp fx of surg nk of unsp humer, 7thK

This code describes a specific type of humerus fracture where the bone is broken at the surgical neck, but the broken pieces are still in their normal alignment (nondisplaced). It is a two-part fracture, meaning the humerus is broken into two distinct pieces. The "subsequent encounter for fracture with nonunion" indicates that the fracture has failed to heal properly after an initial treatment period.

Use this code when documenting follow-up care for a patient whose surgical neck humerus fracture, initially nondisplaced and a two-part break, has not united. This applies to situations where the physician is assessing the nonunion, planning further treatment for the nonunion (e.g., surgery, bone stimulation), or managing complications related to the nonunion. It should be used after the initial healing phase has passed without successful union.

• Ensure documentation clearly states "nonunion" and specifies the surgical neck of the humerus.
• Verify that the fracture was initially nondisplaced and a two-part fracture.
• This code is for subsequent encounters; an initial encounter for this specific fracture would use a different code.
