OAR 436-035-0375: Abdomen

Use the following classifications when impairment has resulted from a permanent and palpable defect in the supporting structures of the abdominal wall: (1) Class 1: 5% for a slight protrusion at the site of the defect with increased abdominal pressure that is readily reducible; or occasional mild discomfort at the site of the defect, which limits the worker in one or more activities of daily living (ADL). (2) Class 2: 15% for frequent or persistent protrusion at the site of the defect with increased pressure that is manually reducible; or frequent discomfort, which limits the worker from heavy lifting, but does not hamper some ADL. (3) Class 3: 25% for persistent, irreducible, or irreparable protrusion at the site of the defect and there is a limitation in the worker’s ADL.
