P55 vs R76.0
P55 (Hemolytic disease of newborn) compared with R76.0 (Raised antibody titer), 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. R76.0 carries an Excludes1 note covering P55: “isoimmunization affecting newborn (P55.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
