Information for Patients


Twins, Triplets, Multiple Births

If you are pregnant with more than one baby, you are far from alone. Multiple births are up in the United States. More women are having babies after age 30 and more are taking fertility drugs. Both boost the chance of carrying more than one baby. A family history of twins also makes multiples more likely.

Years ago, most twins came as a surprise. Now, most women know about a multiple pregnancy early. Women with multiple pregnancies should see their health care providers more often than women who are expecting one baby. Multiple pregnancy babies have a much higher risk of being born prematurely and having a low birth weight. There is also more of a risk of disabilities. Some women have to go on bed rest to delay labor. Finally, they may deliver by C-section, especially if there are three babies or more.

Parenting multiples can be a challenge. Volunteer help and support groups for parents of multiples can help.

ICD-10 Footnotes

General Equivalence Map Definitions
The ICD-10 and ICD-9 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.
