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

This code signifies a penetrating injury to the right posterior chest wall, such as from a nail or sharp object, that does not involve a retained foreign body. The wound extends through the skin and subcutaneous tissue but does not breach the pleural space or enter the thoracic cavity.

This code is appropriate for documenting an initial encounter for a puncture wound to the right back, where clinical assessment confirms no foreign material is present and imaging (if performed) rules out intrathoracic penetration. Examples include accidental stabs from sharp objects like pencils or small tools that do not fully enter the chest.

• Ensure documentation explicitly states "without foreign body" and "without penetration into thoracic cavity."
• Laterality (right) and anatomical site (back wall of thorax) are crucial for accurate code selection.
• Confirm this is the initial encounter for the injury; subsequent care would use a different seventh character.
