Fx unsp part of scapula, l shoulder, subs for fx w malunion

This code signifies a fracture of an unspecified part of the left scapula that has previously been treated, but has healed in an unsatisfactory position, resulting in a malunion. This indicates a complication of the initial fracture healing process, leading to potential functional impairment.

This code is appropriate for follow-up encounters where a patient is being managed for a left scapular fracture that has healed incorrectly. It should be used when documentation explicitly states "malunion" of a left scapular fracture, and the specific part of the scapula is not identified.

• Ensure documentation clearly specifies "malunion" and the left side.
• If the specific part of the scapula is known, a more precise code from the S42.1- series should be used.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
