Rebound abdominal tenderness, unspecified site

This code signifies the presence of rebound tenderness in the abdomen, a clinical sign often indicative of peritoneal irritation or inflammation. It describes a physical exam finding where pain is elicited upon quick release of pressure from the abdominal wall, without specifying the exact quadrant or region.

Assign this code when documentation clearly states "rebound tenderness" without further localization (e.g., "rebound tenderness, unspecified site" or simply "rebound tenderness"). This finding is frequently noted during the assessment of acute abdominal pain, such as suspected appendicitis, peritonitis, or diverticulitis, when a definitive diagnosis is not yet established or is not the primary focus of the encounter.

• Do not use this code if the specific site of rebound tenderness (e.g., right lower quadrant) is documented; instead, use a more specific R10.82- code.
• This code represents a symptom/sign and should be sequenced after the definitive diagnosis if known and confirmed.
• Ensure the medical record explicitly states "rebound tenderness" to support the use of this code.
