Unspecified injury of superior mesenteric artery, sequela

This code signifies a long-term or late effect resulting from an unspecified injury to the superior mesenteric artery. This could involve chronic complications such as stenosis, aneurysm, or chronic ischemia that developed as a direct consequence of a past, unspecific trauma to this vital abdominal artery. The initial injury itself is no longer active, but its lasting impact is being addressed.

Use this code when documenting conditions that are residual effects of a previous, unspecified injury to the superior mesenteric artery. This applies when the acute phase of the original injury has passed, and the patient is now being treated for chronic sequelae. Examples include follow-up for chronic abdominal pain or malabsorption attributed to a prior, unspecified SMA injury.

• Always ensure documentation clearly links the current condition to a past, unspecified superior mesenteric artery injury.
• This code requires a seventh character "S" for sequela, indicating a late effect.
• Avoid using this code for acute injuries; instead, use appropriate acute injury codes for the initial encounter.
