J09 vs P37
J09 (Influenza due to certain identified influenza viruses) compared with P37 (Other congenital infectious and parasitic diseases), from the official CMS tabular data. Both may be reported when both conditions are documented (Excludes2).
Can these codes be reported together?
Yes, when both are documented. P37 carries an Excludes2 note covering J09: “infectious diseases not specific to the perinatal period (A00-B99, J09, J10.-)”
Excludes2 marks distinct conditions — both may be reported when both are documented.
