Partial placenta previa NOS or without hemor, unsp trimester

This code signifies a condition where the placenta partially covers the internal cervical os, but without any associated bleeding. It indicates a diagnosis of partial placenta previa where the specific trimester of pregnancy is not documented or specified.

Use this code when documentation confirms a partial placenta previa without hemorrhage, and the provider has not specified the trimester. This typically occurs during routine prenatal ultrasounds or when a patient presents with no bleeding but a low-lying placenta is identified.

• Do not use this code if hemorrhage is documented; instead, select a code from O44.2 with a fifth character indicating hemorrhage.
• If the trimester is specified, select the appropriate code from O44.21-O44.23.
• Always sequence this code as a secondary diagnosis if the primary reason for the encounter is related to another obstetric complication.
