Miscarriage

Also called: Spontaneous abortion

A miscarriage is the loss of pregnancy from natural causes before the 20th week of pregnancy. Most miscarriages occur very early in the pregnancy, often before a woman even knows she is pregnant. There are many different causes for a miscarriage. In most cases, there is nothing you can do to prevent a miscarriage.

Factors that may contribute to miscarriage include

  • A genetic problem with the fetus. This is the most common cause in the first trimester.
  • Problems with the uterus or cervix. These contribute in the second trimester.
  • Polycystic ovary syndrome

Signs of a miscarriage can include vaginal spotting or bleeding, abdominal pain or cramping, and fluid or tissue passing from the vagina. Although vaginal bleeding is a common symptom of miscarriage, many women have spotting early in their pregnancy but do not miscarry. But if you are pregnant and have bleeding or spotting, contact your health care provider immediately.

Women who miscarry early in their pregnancy usually do not need any treatment. In some cases, you may need a procedure called a dilatation and curettage (D&C) to remove tissue remaining in the uterus.

Counseling may help you cope with your grief. Later, if you do decide to try again, work closely with your health care provider to lower the risks. Many women who have a miscarriage go on to have healthy babies.

Vaginal Bleeding

Also called: Dysfunctional Uterine Bleeding, Uterine Bleeding

Menstruation, or period, is a woman's monthly bleeding. Abnormal vaginal bleeding is different from normal menstrual periods. It could be bleeding that is between periods, lasts several weeks, or happens before puberty or after menopause. Causes can include

  • Uterine fibroids or polyps
  • Hormone problems
  • Hormone pills, such as birth control pills and menopausal hormone therapy
  • Cancer of the cervix, ovaries, uterus or vagina
  • Thyroid problems

Bleeding during pregnancy can have several different causes. It is not always a serious problem, but to be safe you should always contact your healthcare provider.

Pelvic exams, blood tests and other procedures can help your healthcare provider diagnose the problem. Treatment depends on the cause.

  • Dysfunctional uterine bleeding (DUB)

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.
