Low lying placenta with hemorrhage, first trimester

This code signifies a condition where the placenta is implanted in the lower uterine segment, close to or covering the internal cervical os, and is accompanied by vaginal bleeding during the first trimester of pregnancy. This is a preliminary diagnosis that may evolve into placenta previa as the pregnancy progresses.

Assign this code when documentation explicitly states "low-lying placenta" with associated hemorrhage occurring within the first 13 weeks and 6 days of gestation. Supporting documentation includes ultrasound reports confirming placental location and clinical notes detailing vaginal bleeding.

• Ensure the documentation specifies "low-lying placenta" and not "placenta previa" for this code.
• Verify the gestational age to confirm the hemorrhage occurred in the first trimester.
• Code any associated symptoms or complications separately, if applicable and documented.
