Low lying placenta NOS or without hemor, second trimester

This code signifies a diagnosis of a low-lying placenta identified during the second trimester of pregnancy, where the placental edge is close to, but not covering, the internal cervical os, and there is no associated bleeding. It indicates a potential risk factor for complications later in pregnancy, such as placenta previa, but does not represent an active hemorrhage.

Use this code when documentation explicitly states "low-lying placenta" or "placenta near os" without hemorrhage, specifically identified between 14 weeks 0 days and 27 weeks 6 days gestation. This applies to ultrasound findings or clinical assessments confirming the placental position relative to the cervix during the second trimester.

• Ensure the documentation specifies "second trimester" for accurate code assignment; otherwise, a different trimester code may be appropriate.
• Do not use this code if hemorrhage is documented; instead, select a code that includes hemorrhage (e.g., O44.02, O44.12, O44.22, O44.32).
• This code is for a finding of low-lying placenta, not a confirmed placenta previa; if placenta previa is diagnosed, a more specific code should be chosen.
