Open bite of unsp bk wl of thorax w/o penet thor cav, sqla

This code describes a healed or residual effect of an open wound to the posterior aspect of the chest wall that did not extend into the thoracic cavity. The injury involved a bite, and the specific location on the back wall is not documented.

Use this code when documenting a long-term complication or late effect of a previously sustained open bite to the back of the thorax. This applies when the initial injury has resolved, but there are still lingering issues or conditions directly attributable to that bite, and there was no penetration into the chest cavity.

• Ensure the documentation clearly indicates a "sequela" or "late effect" of the original injury.
• Verify that the bite was to the posterior thorax and explicitly states no penetration into the thoracic cavity.
• Confirm that the specific back wall location (e.g., scapular region, vertebral column) is unspecified in the medical record.
