Placentitis, unspecified trimester, other fetus

This code signifies inflammation of the placenta (placentitis) occurring at any point during a pregnancy, affecting a fetus when the specific trimester is not documented. It indicates a non-specific type of placentitis, where the exact cause or detailed characteristics are not specified.

Apply this code when documentation confirms placentitis in a multifetal pregnancy, but the specific trimester of onset is not recorded, and the type of placentitis is not further elaborated. This code is appropriate when the medical record indicates "placentitis, unspecified trimester, other fetus" without additional details.

• Ensure documentation explicitly states "unspecified trimester" and "other fetus" for accurate code assignment.
• Do not use this code if the trimester is known; instead, select a more specific O41.14x code.
• Consider additional codes for any associated maternal or fetal complications, such as premature labor or fetal distress.
