Health Problems in Pregnancy
Every pregnancy has some risk of problems. The causes can be conditions you already have or conditions you develop. They also include being pregnant with more than one baby, previous problem pregnancies, or being over age 35. They can affect your health and the health of your baby.
If you have a chronic condition, you should talk to your health care provider about how to minimize your risk before you get pregnant. Once you are pregnant, you may need a health care team to monitor your pregnancy. Examples of common conditions that can complicate a pregnancy include
- Heart disease
- High blood pressure
- Kidney problems
- Autoimmune disorders
- Sexually transmitted diseases
- Diabetes
- Cancer
- Infections
Other conditions that can make pregnancy risky can happen while you are pregnant - for example, gestational diabetes and Rh incompatibility. Good prenatal care can help detect and treat them.
Some discomforts, like nausea, back pain, and fatigue, are common during pregnancy. Sometimes it is hard to know what is normal. Call your doctor or midwife if something is bothering or worrying you.

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.
