A Combat Zone Period Observation is a clinical statement indicating the self-reported date range(s)when a person worked in what is considered a combat zone. Both civilian workers, such as Department of Defense contractors, and military service members could have worked in combat zones. Many people who have served in the military seek care first outside of the Veterans Health Administration system. Collecting this observation can facilitate important conversations about possible related health concerns, potentially prompting referral to the Department of Veterans’ Affairs (VA).

Slices

This structure defines the following Slices:

- The element Observation.category.coding is sliced based on the value of value:code
- The element Observation.code.coding is sliced based on the value of value:code
