Low lying placenta NOS or without hemorrhage, unsp trimester

This code describes a condition where the placenta is implanted in the lower uterine segment, close to or covering the internal cervical os, without specifying the exact distance from the os and without any associated bleeding. It indicates a potential risk for complications during pregnancy and delivery due to the placenta's position.

Use this code when documentation indicates a "low-lying placenta" or "placenta previa NOS" without further specification of the degree of previa (e.g., marginal, partial, complete) and without any mention of hemorrhage. This code is appropriate when the trimester is not specified or is unknown.

• Do not use this code if the documentation specifies any degree of placenta previa (e.g., marginal, partial, complete); instead, use a more specific O44.1- or O44.2- code.
• If hemorrhage is documented, even with a low-lying placenta, use a code from O44.0- or O44.2-.
• Always review the entire medical record for more specific details regarding placental location, degree of previa, and presence or absence of hemorrhage to ensure the most precise code is selected.
