Disp fx of acromial process, l shldr, subs for fx w nonunion

This code signifies a fracture of the acromial process of the left shoulder that is no longer in its anatomical position. The patient is in a subsequent phase of care, and the fracture has failed to heal properly, resulting in a nonunion.

Apply this code when documenting ongoing treatment for a left acromial fracture that was initially displaced and has now been diagnosed with nonunion. This is appropriate for follow-up visits, surgical interventions for nonunion, or rehabilitation related to the unhealed fracture.

• Ensure documentation clearly specifies "left" shoulder and "acromial process" to differentiate from other scapular fractures.
• Confirm the "subsequent encounter" and "nonunion" status are explicitly stated in the medical record.
• Always sequence this code with any associated external cause codes or codes for complications of surgical or medical care, if applicable.
