Unsp opn wnd r bk wl of thorax w/o penet thor cavity, subs

This code signifies an open wound located on the right side of the back of the chest wall, where the specific nature of the wound (e.g., laceration, puncture) is not documented. Importantly, this wound does not extend into the thoracic cavity, meaning the lungs or other internal organs are not affected. The "D" seventh character indicates this is a subsequent encounter for care after the initial treatment phase.

Use this code for follow-up visits or ongoing treatment of an open wound on the right posterior thorax that was previously treated. This applies when the wound is still open and requires further medical attention, such as wound care, dressing changes, or monitoring for healing, and there is no documentation specifying the type of open wound.

• Ensure documentation clearly states "right back wall of thorax" and "without penetration into thoracic cavity."
• Confirm this is a subsequent encounter; for initial treatment, use the "A" seventh character.
• If the specific type of open wound is documented (e.g., laceration, puncture), a more specific code should be used.
