Primary blast injury of duodenum, sequela

This code describes a long-term complication or residual effect stemming from a primary blast injury that specifically affected the duodenum. It indicates that the patient has previously sustained a direct injury to the duodenum from an explosive device, and is now presenting with a related, ongoing condition.

Use this code when documenting a patient's current medical condition that is a direct consequence of a past primary blast injury to the duodenum. This would apply to follow-up visits for chronic issues, or when a new problem arises that is clearly linked to the original blast trauma.

• Ensure the medical record clearly documents a prior primary blast injury to the duodenum and a causal link to the current sequela.
• Do not use for acute blast injuries; this code is specifically for residual effects.
• Assign additional codes for the specific manifestation of the sequela (e.g., stricture, fistula).
