Hello coders -

I am hoping you can help me. I code professional E&M for various specialties. Some of the providers like to list codes in their impression like I am going to show you below. These tend to stump me on what to order and then the order.
For example...
Patient with abdominal pain secondary to colitis.
Metabolic acidosis secondary to above.
Dehydration secondary to above.
Hypertension stable.

How would you code this? I don't know if I only code one, two or all.

Thanks!!!
