Information for Patients


Infections and Pregnancy

If you are pregnant, an infection can be more than just a problem for you. Some infections can be dangerous to your baby. You can help yourself avoid infections:

  • Don't eat raw or undercooked meat
  • Don't share food or drinks with other people
  • Wash your hands frequently
  • Don't empty cat litter. Cats can transmit toxoplasmosis.

You may need to take medicines or get a vaccine to prevent an infection in your baby. For example, you may need to take antibiotics if you develop an infection with group B strep, or take medicines if you have genital herpes. Only some medicines and vaccines are safe during pregnancy. Ask your health care provider about how best to protect you and your baby.

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.
