P96 vs T39
P96 (Other conditions originating in the perinatal period) compared with T39 (Poisoning by, adverse effect of and underdosing of nonopioid analgesics, antipyretics and antirheumatics), from the official CMS tabular data. Both may be reported when both conditions are documented (Excludes2).
Can these codes be reported together?

Excludes2 marks distinct conditions — both may be reported when both are documented.
