Premature separation of placenta, unsp, second trimester

This code signifies an abruptio placentae occurring during the second trimester of pregnancy where the specific type or cause of the separation is not documented. It indicates the premature detachment of the placenta from the uterine wall before the delivery of the fetus, without further specification.

This code is appropriate when documentation clearly states premature separation of the placenta in the second trimester, but lacks details regarding the extent, type (e.g., partial, complete), or specific cause of the abruption. Use it when the provider's notes simply state "abruptio placentae, second trimester, unspecified."

• Do not use this code if the documentation specifies the type of placental separation (e.g., partial, complete) or if the trimester is clearly indicated as first or third.
• Always review the entire medical record for more specific details regarding the placental abruption to avoid using an "unspecified" code.
• Sequence this code as a principal diagnosis when it is the primary reason for the encounter, or as a secondary diagnosis if it is a co-morbidity affecting the pregnancy.
