Other placental disorders, third trimester

This code signifies any placental abnormality or dysfunction occurring during the third trimester of pregnancy that is not specifically classified elsewhere. It encompasses a range of conditions affecting the placenta's structure or function, excluding those with more specific ICD-10-CM codes.

This code is appropriate when documentation indicates a placental disorder in the third trimester that doesn't fit a more specific diagnosis, such as placenta previa or placental abruption. Supporting documentation should clearly state the presence of a placental anomaly and its occurrence in the third trimester.

• Ensure the documentation explicitly states "third trimester" for accurate code assignment.
• Differentiate from more specific placental disorders (e.g., O43.0- for placenta previa, O45.- for placental abruption).
• This code should be used when the specific nature of the placental disorder is not further elaborated or does not have a dedicated code.
