P84 vs P91.6
P84 (Other problems with newborn) compared with P91.6 (Hypoxic ischemic encephalopathy [HIE]), 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. P84 carries an Excludes1 note covering P91.6: “hypoxic ischemic encephalopathy [HIE] (P91.6-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
