Maternal care for transverse and oblique lie, fetus 4

This code signifies specialized prenatal care provided to a pregnant patient whose fourth fetus is presenting in a transverse (sideways) or oblique (diagonal) position within the uterus. These fetal malpositions can complicate vaginal delivery and often necessitate interventions such as external cephalic version or planned cesarean section.

Use this code when documentation clearly indicates maternal care is being provided specifically due to a transverse or oblique fetal lie, and it is explicitly stated that this is the fourth fetus in a multifetal gestation. This code is appropriate for antenatal encounters where this condition is being monitored or managed.

• Ensure the documentation specifies "fetus 4" to justify the final character.
• Do not use this code for a singleton pregnancy; specific codes exist for singletons.
• Code any associated complications or interventions (e.g., failed external cephalic version) separately.
