Information for Medical Professionals
Information for Patients
Also called: Abdominal pregnancy, Tubal pregnancy
The uterus, or womb, is the place where a baby grows when a woman is pregnant. If you have an ectopic pregnancy, the fertilized egg grows in the wrong place, outside the uterus, usually in the fallopian tubes. The result is usually a miscarriage.
Ectopic pregnancy can be a medical emergency if it ruptures. Signs of ectopic pregnancy include
- Abdominal pain
- Shoulder pain
- Vaginal bleeding
- Feeling dizzy or faint
Get medical care right away if you have these signs. Doctors use drugs or surgery to remove the ectopic tissue so it doesn't damage your organs. Many women who have had ectopic pregnancies go on to have healthy pregnancies later.

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.
