Partial placenta previa with hemorrhage, first trimester

This code signifies a condition where the placenta partially covers the internal cervical os during the first trimester of pregnancy, accompanied by vaginal bleeding. This partial coverage indicates that the placenta is implanted low in the uterus but does not completely obstruct the cervix. The hemorrhage component denotes active bleeding associated with this placental position.

Apply this code when documentation confirms a diagnosis of partial placenta previa with active bleeding occurring before the 14th week of gestation. This diagnosis is typically made via ultrasound and clinical assessment of vaginal bleeding in early pregnancy. Supporting documentation should clearly state "partial placenta previa," "hemorrhage," and "first trimester."

• Ensure the documentation specifies "partial" previa; do not use for complete or marginal previa.
• Verify the trimester is explicitly stated as "first trimester" to avoid miscoding.
• Confirm active bleeding is present; if no hemorrhage, a different code for partial previa without hemorrhage would be appropriate.
