Maternal care for oth rhesus isoimmun, unsp tri, fetus 5

This code signifies maternal care for a pregnancy complicated by rhesus isoimmunization, specifically when the type of isoimmunization is not Rh(D) but another rhesus antigen (e.g., Rhc, Rhe, RhE). The specific trimester of pregnancy is not documented, and the code indicates this is for the fifth fetus in a multiple gestation.

Apply this code when documentation confirms maternal care for rhesus isoimmunization other than Rh(D), and the specific trimester is not recorded. This code is also used when the pregnancy involves five fetuses, and the isoimmunization is relevant to the fifth fetus. Documentation should specify the type of rhesus isoimmunization (e.g., anti-c, anti-E) and the fetal count if applicable.

• Do not use this code for Rh(D) isoimmunization; refer to codes in the O36.01- or O36.02- series.
• Ensure documentation clearly specifies "other rhesus isoimmunization" and not just "Rh isoimmunization" if the specific type is unknown.
• Verify the fetal count (fifth fetus) is explicitly stated in the medical record to support the fifth digit.
