Uterine Cancer

Also called: Endometrial cancer

The uterus, or womb, is the place where a baby grows when a women is pregnant. There are different types of uterine cancer. The most common type starts in the endometrium, the lining of the uterus. This type is also called endometrial cancer.

The symptoms of uterine cancer include

• Abnormal vaginal bleeding or discharge
• Trouble urinating
• Pelvic pain
• Pain during intercourse

Uterine cancer usually happens after menopause. It is more common in women who have obesity. You also have a higher risk if you took estrogen-only hormone replacement therapy (menopausal hormone therapy) for many years.

Tests to find uterine cancer include a pelvic exam, imaging tests, and a biopsy. The most common treatment is a hysterectomy, which is surgery to remove the uterus. Sometimes the surgery also removes the ovaries and fallopian tubes. Other treatments include hormone therapy, radiation therapy, and chemotherapy. Some women get more than one type of treatment.

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.
