Minor laceration of unsp innominate or subclav art, sequela

This diagnosis code signifies a long-term complication or late effect stemming from a minor tear in an unspecified innominate or subclavian artery. It indicates that the initial injury has healed, but residual issues or conditions persist as a direct consequence of that prior trauma.

This code is appropriate when documenting conditions that arise months or years after a minor laceration to these specific arteries, such as chronic pain, nerve damage, or vascular insufficiency directly attributable to the original injury. It should be used when the patient is no longer in the acute phase of treatment for the laceration itself.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the previous minor laceration of the innominate or subclavian artery.
• Verify that the laterality (left/right) of the artery was not specified in the original injury documentation if using this "unspecified" code.
