Oth injury of right pulmonary blood vessels, sequela

This code signifies a long-term or late effect resulting from a previously sustained, specific but not otherwise classified injury to the blood vessels of the right lung. This could include residual damage or complications that manifest after the initial acute phase of the trauma has passed.

Apply this code when documenting a current condition directly attributable to an old injury of the right pulmonary arteries or veins, where the specific type of injury (e.g., laceration, contusion) is known but doesn't have a more precise code. This is appropriate for follow-up encounters addressing chronic issues stemming from such trauma.

• Always sequence this S-code as a secondary diagnosis, following the code for the specific sequela or current condition being treated.
• Ensure documentation clearly links the current condition to a past injury of the right pulmonary blood vessels.
• Verify that the injury is "other specified" and not better described by a more specific S25.4- code.
