Information for Patients


Childbirth Problems

While childbirth usually goes well, complications can happen. They can cause a risk to the mother, baby, or both. Possible complications include

  • Preterm (premature) labor, when labor starts before 37 completed weeks of pregnancy
  • Problems with the umbilical cord
  • Problems with the position of the baby, such as breech, in which the baby is going to come out feet first
  • Birth injuries

For some of these problems, the baby may need to be delivered surgically by a Cesarean section.

  • Assisted delivery with forceps
  • Brachial plexus injury in newborns
  • Breech birth
  • Caput succedaneum
  • Fractured clavicle in the newborn
  • Meconium aspiration syndrome
  • Placenta previa
  • Premature rupture of membranes
  • Sheehan syndrome
  • Vacuum-assisted delivery
  • When you pass your due date

General Equivalence Map Definitions
The ICD-9 and ICD-10 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
