Other and unspecified superficial injury of shoulder and upper arm, infected

This code signifies a superficial injury to the shoulder or upper arm that has become infected. This includes conditions like infected abrasions, contusions, or minor lacerations affecting the skin and subcutaneous tissue in this region, where the specific type of superficial injury is not further detailed or is unknown.

Apply this code when documentation clearly indicates a superficial injury of the shoulder or upper arm that has developed an infection. This is appropriate for cases where the specific nature of the original superficial injury (e.g., abrasion, blister) is not specified, but the presence of infection is confirmed.

• Always sequence the infection as a secondary diagnosis if the primary reason for the encounter is the initial injury or a more severe underlying condition.
• Ensure documentation specifies both the superficial nature of the injury and the presence of infection.
• Differentiate from open wounds (e.g., lacerations) that are inherently infected, which would typically be coded to an open wound category with an infection complication.
