P28.2 vs P28.4
P28.2 (Cyanotic attacks of newborn) compared with P28.4 (Other apnea of newborn), 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. P28.2 carries an Excludes1 note covering P28.4: “apnea of newborn (P28.3- - P28.4-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
