Open bite of r bk wl of thorax w penet thoracic cavity, subs

This code signifies an open wound on the right posterior chest wall, caused by an animal or human bite, that has breached the thoracic cavity. It indicates that the patient is receiving follow-up care for this injury after the initial treatment.

Apply this code for patients presenting for subsequent treatment of a previously diagnosed open bite wound to the right back of the thorax that penetrated the chest cavity. This includes wound care, monitoring for complications, or management of ongoing issues related to the initial injury.

• Ensure documentation specifies "right back wall of thorax" and "penetration into thoracic cavity."
• Verify the encounter is for follow-up care, not the initial treatment, as indicated by the "D" seventh character.
• Code any associated infections or complications separately.
