High level blast overpressure in milt op, sequela

This code describes the long-term or residual effects resulting from exposure to high-level blast overpressure during military operations. These sequelae can manifest as a range of physical and psychological conditions that persist after the initial injury has healed or stabilized. It specifically points to the lasting impact of such an event.

Use this code when documenting conditions that are a direct consequence of a high-level blast overpressure injury sustained in a military setting, and these conditions are now chronic or permanent. This would apply to patients presenting for treatment of ongoing hearing loss, traumatic brain injury (TBI) sequelae, or chronic pain syndromes directly attributable to such an event. It is appropriate for follow-up care for these persistent issues.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., TBI sequela, hearing loss).
• Ensure documentation clearly links the current condition to a past high-level blast overpressure event in military operations.
• Do not use for acute blast injuries; this code is exclusively for the sequelae.
