Premature separation of placenta, unsp, first trimester

This code signifies the premature detachment of the placenta from the uterine wall before the fetus is delivered, occurring specifically within the first trimester of pregnancy. This condition, also known as abruptio placentae, is unspecified regarding its severity or type of separation.

Apply this code when documentation indicates a diagnosis of placental abruption during the first trimester, and no further details regarding the type or extent of the separation are provided. This diagnosis is typically supported by clinical findings such as vaginal bleeding, abdominal pain, uterine tenderness, and fetal distress (if applicable at this gestational age).

• Ensure the documentation explicitly states "first trimester" for accurate gestational age assignment.
• Do not use this code if the abruption is specified as partial, complete, or retroplacental hemorrhage; more specific codes exist for those scenarios.
• Always sequence this code as a principal diagnosis when it is the primary reason for the encounter.
