E80.6 vs P56
E80.6 (Other disorders of bilirubin metabolism) compared with P56 (Hydrops fetalis due to hemolytic disease), 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. P56 carries an Excludes1 note covering E80.6: “Dubin-Johnson syndrome (E80.6)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
