P80 vs T68
P80 (Hypothermia of newborn) compared with T68 (Hypothermia), 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. T68 carries an Excludes1 note covering P80: “hypothermia of newborn (P80.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
