Lac w/o fb of unsp bk wl of thorax w/o penet thor cav, sqla

This code describes the long-term effects or complications arising from a past laceration to an unspecified area of the back of the thorax. The original injury did not involve a foreign body and did not penetrate the thoracic cavity. This code is used when the patient is presenting for care related to the residual issues from that healed injury.

Use this code when documenting a patient encounter for a sequela (e.g., scar tissue, chronic pain, nerve damage) resulting from a previously sustained laceration to the back of the chest wall. This applies when the initial injury has healed, and the patient is now being treated for a lasting consequence of that trauma.

• Assign this code for conditions that are residual effects of a healed injury, not for the acute injury itself.
• Ensure documentation clearly links the current condition to a past laceration of the back of the thorax.
• Always use the 7th character 'S' for sequela when reporting long-term effects of an injury.
