Milt op involving biological weapons, milt, subs

This code signifies a patient's follow-up care for health issues directly resulting from exposure to biological weapons during military operations. It indicates that the initial injury or illness has already been addressed, and the current encounter is for ongoing management, monitoring, or treatment of related complications.

Apply this code for subsequent visits where a military service member is receiving continued medical attention for conditions like chronic infections, organ damage, or long-term sequelae stemming from a past biological weapon incident. This includes routine check-ups, medication adjustments, or therapy sessions related to the initial exposure.

• Ensure documentation clearly states the encounter is for follow-up care related to a past biological weapon exposure.
• Always pair this code with an external cause code (e.g., T-code for specific effects) to fully describe the patient's condition.
• Verify the "D" seventh character is appropriate for subsequent encounters; "A" is for initial, and "S" for sequela.
