Pnctr w fb of r bk wl of thorax w/o penet thor cavity, init

This code signifies a penetrating injury to the right posterior chest wall caused by a sharp object, where a foreign body (e.g., splinter, glass shard) remains embedded in the tissue. Importantly, the injury does not extend through the pleura or into the lung or mediastinum.

Apply this code for patients presenting with a puncture wound on the right side of their back, where a foreign object is visible or palpable, and imaging (e.g., X-ray, CT scan) confirms that the object has not entered the thoracic cavity. This code is appropriate for the initial treatment of such an injury.

• Ensure documentation explicitly states "right back wall of thorax" and "without penetration into thoracic cavity."
• Verify the presence of a foreign body; if no foreign body is present, a different code for puncture wound without foreign body should be used.
• The "A" at the end indicates an initial encounter for this injury. Subsequent encounters would use different seventh characters.
