Placentitis, unsp trimester, not applicable or unspecified

This code describes inflammation of the placenta (placentitis) when the specific trimester of pregnancy is not documented or is not applicable. Placentitis can be a serious condition, potentially leading to adverse pregnancy outcomes such as preterm labor, fetal infection, or stillbirth.

Use this code when the medical record clearly indicates a diagnosis of placentitis, but the documentation does not specify the trimester of pregnancy. This code is appropriate when the provider's notes simply state "placentitis" without further detail regarding the gestational period.

• Always attempt to clarify the trimester with the provider if possible, as more specific codes exist for each trimester.
• Do not use this code if the documentation specifies a trimester (e.g., first, second, or third trimester placentitis).
• Consider co-reporting with codes for associated conditions such as chorioamnionitis (O41.12-) if documented.
