Prem separtn of placenta w coag defect, unsp, unsp trimester

This code signifies the premature detachment of the placenta from the uterine wall before the fetus is delivered, specifically when a coagulation defect is present. The exact trimester of occurrence is not specified, nor is the specific type of coagulation defect. This condition can lead to significant maternal and fetal morbidity and mortality.

Use this code when documentation clearly indicates placental abruption in a pregnant patient, accompanied by a diagnosed or suspected coagulation disorder. This code is appropriate when the medical record does not specify the trimester of pregnancy or the exact nature of the coagulation defect.

• Ensure documentation explicitly links the placental abruption to a coagulation defect.
• Avoid using this code if the trimester is known; instead, select a more specific O45.0- code with a specified trimester.
• If the specific coagulation defect is identified, consider coding it as a secondary diagnosis.
