Milt op involving explosion of guided missile, milt, sequela

This code describes the long-term effects or complications arising from injuries sustained by military personnel due to the explosion of a guided missile during military operations. It signifies that the initial injury event has passed, and the patient is now presenting with residual conditions directly attributable to that specific incident.

Use this code when documenting a patient's current medical condition that is a direct consequence of a guided missile explosion experienced during military service. This applies to follow-up encounters for chronic pain, organ damage, psychological trauma, or other persistent health issues stemming from the original event.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., T90.5XXS for sequela of intracranial injury).
• Ensure documentation clearly links the current condition to the past military incident involving a guided missile explosion.
• Verify the patient's military personnel status is documented to support the use of this specific external cause code.
