Low level blast overpressure in military operations, sequela

This code signifies a long-term health condition or complication resulting from exposure to low-level blast overpressure during military operations. It indicates that the initial injury or exposure has resolved, but its lasting effects are now being treated or evaluated. This could encompass a range of chronic physical or psychological sequelae.

Apply this code when documenting the ongoing management of conditions directly attributed to past low-level blast overpressure exposure in a military context. This includes follow-up visits for persistent symptoms, chronic pain, neurological deficits, or mental health disorders that are clearly linked to such an event. It is appropriate when the acute phase of the blast exposure is over, and the patient is presenting for treatment of the residual effects.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., TBI, PTSD, chronic pain).
• Ensure documentation clearly links the current condition to a history of low-level blast overpressure in military operations.
• The "S" in the seventh character indicates sequela, meaning it's for conditions that are the late effects of the initial injury.
