Abrasion of left back wall of thorax, subsequent encounter

This code signifies a superficial injury to the skin on the left side of the posterior chest wall, characterized by scraping or rubbing off of the epidermal layer. It indicates that the patient is receiving follow-up care for this specific abrasion, rather than presenting for the initial injury.

Use this code when a patient returns for a subsequent visit related to an abrasion on the left back wall of the thorax. This includes wound checks, dressing changes, or evaluation of healing progress after the initial treatment has been rendered. It is appropriate for any encounter following the initial presentation of the injury.

• Ensure documentation clearly specifies the "left" side of the back wall of the thorax.
• Confirm the encounter is for follow-up care; use the initial encounter (A) or sequela (S) seventh character as appropriate for other visits.
• Always code any associated infections or complications separately.
