PPHN, PFO and PDA are not supposed to be coded together per the Excludes 1 note. We have many babies with these diagnoses. When PPHN is present in a newborn along with a PFO and/or PDA, I code the PPHN because it is going to be the focus of treatment. If the PDA requires treatment for closure I do go ahead and code it with the PPHN.
On the other hand, our coders will always code the PFO and PDA instead of the PPHN. I feel this is incorrect.
I would love to have feedback from others as to how you code the record when there is PPHN with a PFO and/or PDA?
