Low level blast overpressure in war operations, sequela

This code signifies the long-term or residual effects resulting from exposure to low-level blast overpressure during military combat or war operations. These sequelae can manifest as a range of physical, neurological, or psychological conditions that persist after the initial injury.

Use this code when documenting conditions that are directly attributed to a past incident of low-level blast overpressure experienced in a war zone. This applies to chronic or lasting symptoms, such as persistent headaches, tinnitus, balance issues, or cognitive deficits, where the original blast exposure is identified as the causative event.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past low-level blast overpressure event in war operations.
• The "S" in the seventh character indicates sequela, meaning it's for conditions that are the late effects of the initial injury.
