Laceration of oth blood vessels of thorax, left side, subs

This code signifies a tear or cut in a blood vessel within the left side of the chest, excluding the heart, aorta, or pulmonary artery. This injury has been previously treated and the patient is now receiving follow-up care or treatment for complications.

Apply this code when documenting ongoing care for a patient who sustained a laceration to a non-major thoracic blood vessel on the left side. This includes scenarios such as wound checks, dressing changes, management of infection, or treatment of delayed bleeding related to the initial injury.

• Ensure documentation clearly specifies "left side" and that the blood vessel is not the aorta, pulmonary artery, or a coronary vessel.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine follow-up or care during the healing phase.
• Always code the underlying cause of the laceration (e.g., trauma, iatrogenic) as an additional diagnosis.
