P61.1 vs R71
P61.1 (Polycythemia neonatorum) compared with R71 (Abnormality of red blood cells), 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. R71 carries an Excludes1 note covering P61.1: “polycythemia neonatorum (P61.1)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
Yes, when both are documented. R71 carries an Excludes2 note covering P61.1: “hemorrhagic and hematological disorders of newborn (P50-P61)”
Excludes2 marks distinct conditions — both may be reported when both are documented.
