Prem separtn of placenta w oth coag defect, third trimester

This code signifies the premature detachment of the placenta from the uterine wall during the third trimester of pregnancy, specifically when an additional coagulation defect is present. This condition, known as placental abruption, can lead to significant maternal hemorrhage and fetal distress. The "other coagulation defect" indicates a co-occurring bleeding or clotting disorder contributing to or complicating the abruption.

Use this code when documentation clearly indicates a placental abruption occurring in the third trimester, and the patient also has a diagnosed "other coagulation defect" (e.g., von Willebrand disease, acquired coagulopathy not specified as DIC). Supporting documentation would include obstetric notes detailing the abruption, laboratory results confirming the coagulation defect, and the gestational age at the time of diagnosis.

• Ensure the documentation specifies "third trimester" for accurate code assignment.
• Distinguish "other coagulation defect" from disseminated intravascular coagulation (DIC), which has a separate code.
• Always sequence this code as a primary diagnosis when it is the reason for the encounter, followed by codes for any associated conditions or complications.
