P96 vs T38

P96 (Other conditions originating in the perinatal period) compared with T38 (Poisoning by, adverse effect of and underdosing of hormones and their synthetic substitutes and antagonists, not elsewhere classified), 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. T38 carries an Excludes2 note covering P96: “drug reaction and poisoning affecting newborn (P00-P96)”

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