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

This code signifies a past injury involving a sharp object piercing the right posterior chest wall and entering the thoracic cavity, but without any retained foreign material. The "sequela" designation indicates that this code is used to report a condition or complication that is a residual effect of the original puncture wound, rather than the acute injury itself.

Use this code when documenting a patient presenting with a long-term complication or condition directly resulting from a previous puncture wound to the right back wall of the thorax that penetrated the thoracic cavity. Examples include chronic pain, scar tissue formation, or respiratory issues attributable to the old injury, after the initial acute phase of the wound has passed.

• Always assign an additional code to describe the specific sequela or complication being treated.
• Ensure documentation clearly links the current condition to the previous puncture wound.
• Do not use this code for the initial acute injury; it is strictly for residual effects.
