Unsp opn wnd unsp frnt wall of thrx w/o penet thor cav, sqla

This code signifies a healing or chronic open wound affecting the front of the chest wall, not extending into the chest cavity, where the specific nature of the wound (e.g., laceration, puncture) is not documented. The "sequela" seventh character indicates that this encounter is for the late effects or complications of the original injury, after the acute phase has passed.

This code is appropriate for encounters where a patient presents for follow-up care, management of complications, or treatment of a chronic issue related to a previously sustained open wound of the anterior thorax. Examples include scar revision, chronic wound care, or addressing persistent pain at the site of a healed or partially healed open chest wall injury.

• Ensure documentation clearly states the encounter is for sequelae, not the initial acute injury.
• Verify that the wound is located on the anterior thorax and there is no mention of thoracic cavity penetration.
• If the specific type of open wound is known (e.g., laceration, puncture), a more specific code should be used.
