Oth comp specific to multiple gest, second tri, fetus 3

This code signifies a complication unique to a pregnancy involving three or more fetuses, specifically affecting the third fetus, and occurring during the second trimester (weeks 14 through 27+6 days). These complications are distinct from those common to all multiple gestations and are specific to the individual fetus.

Apply this code when documentation clearly indicates a specific complication (e.g., growth restriction, structural anomaly, or other issue) identified in the third fetus of a multiple gestation during the second trimester. The medical record must explicitly state the specific fetus affected and the gestational age range.

• Ensure the documentation specifies "fetus 3" and not another fetus in the multiple gestation.
• Always sequence this code after the primary code for the specific complication affecting fetus 3.
• Verify the gestational age falls within the second trimester (14 weeks 0 days to 27 weeks 6 days).
