A short section explains the purpose of the SSR.
         An introduction defines the disorder.
         Policy interpretation is in question-and-answer format and explains the evidence we
            need to establish an MDI of IC. The questions and answers also explain how we evaluate
            IC when we determine whether a person is disabled. The questions answered in the SSR
            are listed here:
         
         I. What is IC?
         II. How does a person establish an MDI of IC?
         III. How do we document IC?
         IV. How do we evaluate a person's statements about his or her symptoms and functional
            limitations?
         
         V. How do we find a person disabled based on an MDI of IC?
         VI. How do we use the sequential evaluation process to evaluate IC?
         SSR 15-1p also includes cross references to additional rulings and Program Operating
            Manual System (POMS) instructions.
