R19.36

Epigastric abdominal rigidity

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R19.36 is a billable code used to indicate a diagnosis of epigastric abdominal rigidity.

Key Diagnostic Point:

Epigastric abdominal rigidity refers to a state of increased tension or stiffness in the abdominal muscles located in the epigastric region, which is situated between the rib cage and the navel. This rigidity can be a sign of underlying pathology, often indicating irritation or inflammation of the abdominal organs. Common causes include acute pancreatitis, peptic ulcer disease, or peritonitis. Patients may present with associated symptoms such as abdominal pain, tenderness, and changes in bowel habits. The rigidity may be assessed during a physical examination, where the clinician palpates the abdomen to determine the presence of involuntary muscle contraction. Laboratory findings may include elevated white blood cell counts or imaging studies that reveal organ inflammation or obstruction. Accurate diagnosis is crucial, as epigastric rigidity can signify serious conditions requiring immediate medical intervention.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying conditions that can cause rigidity
  • Need for thorough clinical evaluation to determine cause
  • Potential overlap with other abdominal symptoms
  • Variability in presentation among different patient populations

Audit Risk Factors

  • Inadequate documentation of physical examination findings
  • Failure to link rigidity to a specific diagnosis
  • Misinterpretation of epigastric rigidity as a standalone diagnosis
  • Lack of clarity on associated symptoms or conditions
