Pnctr w/o fb of l frnt wl of thorax w penet thor cav, subs

This code describes a puncture wound to the left anterior chest wall that has breached the thoracic cavity, but without any retained foreign object. This specific code is for use during the healing phase after the initial treatment of the injury.

This code is appropriate for follow-up visits, such as wound checks, dressing changes, or monitoring for complications, after a patient has sustained a penetrating injury to the left front of the chest that entered the pleural space. It would be used when the patient is no longer in the initial active treatment phase of the injury.

• Ensure documentation specifies "left" front wall of thorax and "without foreign body."
• The "D" seventh character indicates a subsequent encounter, meaning care is being provided during the healing or recovery phase.
• Distinguish from initial encounters (A) or sequela (S) encounters.
