Unsp opn wnd unsp bk wl of thorax w/o penet thor cav, init

This code signifies an open wound located on the posterior aspect of the thorax, the specific location of which is not documented. The wound does not extend into the thoracic cavity, meaning there is no penetration of the pleura or other internal structures. This is designated as the initial encounter for this injury.

Use this code for patients presenting with an open wound to the back, such as a laceration, abrasion, or puncture wound, where the exact anatomical location on the back is not specified in the medical record. It is appropriate when the provider explicitly states or implies that the wound does not involve the lung or other intrathoracic organs. This code is only for the initial treatment of the injury.

• Ensure documentation clearly states "unspecified back" and "without penetration into thoracic cavity."
• If the specific location on the back (e.g., scapular region, lumbar region) is documented, a more specific code should be used.
• Verify that this is indeed the initial encounter for this specific injury; subsequent encounters would require a different 7th character.
