P04.1 vs Q86.2
P04.1 (Newborn affected by other maternal medication) compared with Q86.2 (Dysmorphism due to warfarin), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. P04.1 carries an Excludes1 note covering Q86.2: “dysmorphism due to warfarin (Q86.2)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
Yes, when both are documented. Q86.2 carries an Excludes2 note covering P04.1: “nonteratogenic effects of substances transmitted via placenta or breast milk (P04.-)”
Excludes2 marks distinct conditions — both may be reported when both are documented.
