Hey there friend!
Based on my calculation's and understanding of this question, there are multiple ways of actually coding the epigastric which is (due) to the pain and due to acute pancreatitis without necrosis or infection.
One way that you could do this is by using a code which allow's the corneal to correct it self on this left eye, which is used by (H16.032).
Once again, there are multiple ways of doing this, but, the example above is just one example.
Hope this help you!
