D55 vs P58
D55 (Anemia due to enzyme disorders) compared with P58 (Neonatal jaundice due to other excessive hemolysis), 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. P58 carries an Excludes1 note covering D55: “hereditary hemolytic anemias (D55-D58)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
