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

This code signifies a puncture wound on the right side of the back of the chest wall, where a foreign object remains embedded in the tissue. Importantly, this injury does not extend into the thoracic cavity, meaning the lungs or other internal organs are not directly affected. The "sequela" designation indicates that this code is used for complications or conditions arising directly from the initial injury, after the acute phase of the wound has passed.

Use this code when documenting a chronic condition or complication resulting from a past puncture wound to the right posterior chest wall, where a foreign body is still present. This would apply, for example, to persistent pain, infection, or scar tissue formation related to the retained foreign object. It is appropriate for follow-up encounters after the initial treatment of the acute injury.

• Ensure documentation clearly states "right back wall of thorax" and confirms the presence of a foreign body.
• Verify that there is no documentation of penetration into the thoracic cavity.
• The "S" at the end indicates sequela; only use this code for conditions arising from the initial injury, not for the initial acute encounter.
