About the condition
Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.
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.

Pelvic pain occurs mostly in the lower abdomen area. The pain might be steady, or it might come and go. It can be a sharp and stabbing pain in a specific spot, or a dull pain that is spread out. If the pain is severe, it might get in the way of your daily activities.
