Left lower quadrant abdominal rigidity

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 R19.34 is a billable code used to indicate a diagnosis of left lower quadrant abdominal rigidity.

Key Diagnostic Point:

Left lower quadrant abdominal rigidity is a clinical sign characterized by involuntary muscle contraction in the left lower abdominal area, often indicating underlying pathology. This rigidity can be a response to inflammation, irritation, or other pathological processes affecting the abdominal organs, such as the intestines, kidneys, or reproductive organs. Common causes include diverticulitis, appendicitis, renal colic, or gynecological conditions like ectopic pregnancy. The presence of rigidity may suggest peritoneal irritation, which can be a sign of serious conditions requiring immediate medical attention. Clinicians often assess this sign during a physical examination, noting the degree of rigidity and associated symptoms such as pain, tenderness, or distension. Laboratory findings may include elevated white blood cell counts or imaging studies revealing abnormalities in the abdominal organs. Accurate identification and documentation of this sign are crucial for appropriate diagnosis and treatment planning.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation and underlying causes
  • Need for thorough physical examination and history-taking
  • Potential overlap with other abdominal conditions
  • Documentation of associated symptoms and findings

Audit Risk Factors

  • Inadequate documentation of physical examination findings
  • Failure to link the sign to a definitive diagnosis
  • Misinterpretation of abdominal rigidity as a standalone diagnosis
  • Lack of clarity on associated symptoms or clinical context

Specialty Focus

Internal Medicine

Documentation Requirements

Detailed documentation of the physical examination, including the degree of rigidity, associated symptoms, and any relevant history.

Common Clinical Scenarios

Patients presenting with abdominal pain, fever, and rigidity suggestive of diverticulitis or other intra-abdominal pathology.

Billing Considerations

Consideration of comorbid conditions that may complicate the clinical picture.

Emergency Medicine

Documentation Requirements

Acute care documentation must include time of presentation, vital signs, and a thorough assessment of abdominal findings.

Common Clinical Scenarios

Patients with acute abdominal pain and rigidity requiring immediate intervention.

Billing Considerations

Rapid assessment and documentation are critical due to the potential for surgical emergencies.
