Military operations, unspecified, sequela

This code signifies a long-term health condition or injury resulting from an unspecified military operation. It is used when the specific nature of the military operation that caused the sequela is not documented or cannot be determined. This indicates a delayed or residual effect of a past military event.

Apply this code when a patient presents with a current health problem clearly attributed to a past military operation, but the details of that operation are unknown or unspecifiable. This is appropriate for conditions like chronic pain, PTSD, or physical disabilities that are documented as sequelae of military service without further operational specificity.

• Always use with an additional code identifying the specific sequela (e.g., a code for PTSD, chronic pain, or a specific injury).
• The "S" at the end indicates a sequela code, meaning it's for conditions that are residual effects of an earlier injury or disease.
• Ensure documentation clearly links the current condition to a past military operation, even if the operation itself is unspecified.
