Birth Defects

A birth defect is a problem that happens while a baby is developing in the mother's body. Most birth defects happen during the first 3 months of pregnancy. One out of every 33 babies in the United States is born with a birth defect.

A birth defect may affect how the body looks, works or both. Some birth defects like cleft lip or neural tube defects are structural problems that can be easy to see. To find others, like heart defects, doctors use special tests. Birth defects can range from mild to severe. Causes can include

• Genetics
• Exposures to medicines or chemicals. For example, alcohol abuse can cause fetal alcohol syndrome.
• Infections during pregnancy
• Certain medicines. Before you get pregnant, talk to your health care provider about any medicines you take.
• Not getting enough of certain nutrients. For example, not getting enough folic acid before and during pregnancy is a key factor in causing neural tube defects.

For most birth defects, the cause is unknown.

Health care providers can diagnose certain birth defects during pregnancy, with prenatal tests. That's why it important to get regular prenatal care. Other birth defects may not be found until after the baby is born. Sometimes the defect is obvious right away. Other times, the health care provider may not discover it until later in life.

Babies with birth defects often need special care and treatments. The treatments may include surgery, medicines, assistive devices, and therapies.

Eye Diseases

Some eye problems are minor and don't last long. But some can lead to a permanent loss of vision.

Common eye problems include

• Refractive errors
• Cataracts - clouded lenses
• Optic nerve disorders, including glaucoma
• Retinal disorders - problems with the nerve layer at the back of the eye
• Macular degeneration - a disease that destroys sharp, central vision
• Diabetic eye problems
• Conjunctivitis - an infection also known as pinkeye

Your best defense is to have regular checkups, because eye diseases do not always have symptoms. Early detection and treatment could prevent vision loss. See an eye care professional right away if you have a sudden change in vision, if everything looks dim, or if you see flashes of light. Other symptoms that need quick attention are pain, double vision, fluid coming from the eye, and inflammation.

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.

Present on Admission
The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement.
