P00.2 vs P00.82
P00.2 (Newborn affected by maternal infectious and parasitic diseases) compared with P00.82 (Newborn affected by (positive) maternal group B streptococcus (GBS) colonization), 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. P00.2 carries an Excludes1 note covering P00.82: “maternal genital tract or other localized infections (P00.8)”
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. P00.2 carries an Excludes2 note covering P00.82: “newborn affected by (positive) maternal group B streptococcus (GBS) colonization (P00.82)”
Excludes2 marks distinct conditions — both may be reported when both are documented.
