Information for Patients


Abdominal Pain

Your abdomen extends from below your chest to your groin. Some people call it the stomach, but your abdomen contains many other important organs. Pain in the abdomen can come from any one of them. The pain may start somewhere else, such as your chest. Severe pain doesn't always mean a serious problem. Nor does mild pain mean a problem is not serious.

Call your health care provider if mild pain lasts a week or more or if you have pain with other symptoms. Get medical help immediately if

  • You have abdominal pain that is sudden and sharp
  • You also have pain in your chest, neck or shoulder
  • You're vomiting blood or have blood in your stool
  • Your abdomen is stiff, hard and tender to touch
  • You can't move your bowels, especially if you're also vomiting

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.
