Information for Patients


Pregnancy and Drug Use

When you are pregnant, you are not just "eating for two." You also breathe and drink for two. If you smoke, use alcohol or take illegal drugs, so does your unborn baby.

To protect your baby, you should avoid:

  • Tobacco. Smoking during pregnancy passes nicotine, carbon monoxide, and other harmful chemicals to your baby. This could cause many problems for your unborn baby's development. It raises the risk of your baby being born too small, too early, or with birth defects. Smoking can also affect babies after they are born. Your baby would be more likely to develop diseases such as asthma and obesity. There is also a higher risk of dying from sudden infant death syndrome (SIDS).
  • Drinking alcohol. There is no known amount of alcohol that is safe for a woman to drink during pregnancy. If you drink alcohol when you are pregnant, your child could be born with lifelong fetal alcohol syndrome disorders (FASD). Children with FASD can have a mix of physical, behavioral, and learning problems.
  • Illegal drugs. Using illegal drugs such as cocaine and methamphetamines may cause underweight babies, birth defects, or withdrawal symptoms after birth.
  • Misusing prescription drugs. If you are taking prescription medicines, carefully follow your health care provider's instructions. It can be dangerous to take more medicines than you are supposed to, use them to get high, or take someone else's medicines. For example, misusing opioids can cause birth defects, withdrawal in the baby, or even loss of the baby.

If you are pregnant and you are doing any of these things, get help. Your health care provider can recommend programs to help you quit. You and your baby's health depend on it.

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.
