Partial placenta previa with hemorrhage, unsp trimester

This code signifies a condition where the placenta partially covers the internal cervical os, accompanied by active bleeding, but the specific gestational age at the time of diagnosis is not documented. It indicates a complication of pregnancy involving an abnormally implanted placenta and associated hemorrhage.

Apply this code when documentation clearly states "partial placenta previa with hemorrhage" without specifying the trimester. This is appropriate for cases where the provider notes bleeding due to a partially covering placenta but omits the gestational week or trimester.

• Ensure documentation explicitly states "partial" placenta previa; do not use for total or marginal.
• Confirm the presence of hemorrhage; if no bleeding is noted, a different code for placenta previa without hemorrhage should be used.
• Avoid using this code if the trimester is known; instead, select the more specific code that includes the trimester.
