Lac w/o fb of l bk wl of thorax w penet thor cavity, sequela

This code signifies a past injury involving a laceration to the left posterior chest wall that extended into the thoracic cavity, but did not involve a foreign body. It indicates that the patient is currently experiencing a residual effect or complication from this previous traumatic event.

Use this code when documenting a patient presenting with a long-term consequence, such as chronic pain, scar tissue complications, or respiratory issues, directly attributable to a prior penetrating laceration of the left back wall of the thorax. This code is appropriate when the acute injury has resolved, but its lasting impact is still being managed.

• Always sequence this code after the primary diagnosis describing the specific sequela being treated.
• Ensure documentation clearly links the current condition to the previous penetrating thoracic injury.
• Do not use for acute injuries; this code is exclusively for sequelae.
