P50.5 vs P51
P50.5 (Newborn affected by intrauterine (fetal) blood loss from cut end of co-twin's cord) compared with P51 (Umbilical hemorrhage 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. P51 carries an Excludes1 note covering P50.5: “umbilical hemorrhage from cut end of co-twins cord (P50.5)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
