Code Description

ICD-10 R10.32 is a billable code used to indicate a diagnosis of left lower quadrant pain.

Key Diagnostic Point:

Left lower quadrant pain (LLQ pain) refers to discomfort or pain localized in the left lower abdomen. This symptom can arise from various underlying conditions affecting the gastrointestinal, urinary, reproductive, or musculoskeletal systems. Common causes include diverticulitis, ovarian cysts, ectopic pregnancy, and renal colic. Patients may present with acute or chronic pain, which can be sharp, dull, or cramping in nature. Associated symptoms may include nausea, vomiting, changes in bowel habits, urinary symptoms, or menstrual irregularities. Clinical evaluation often involves a thorough history and physical examination, focusing on the onset, duration, and character of the pain, as well as any accompanying symptoms. Diagnostic imaging, such as ultrasound or CT scans, may be warranted to identify the underlying cause. Laboratory tests may include complete blood counts, urinalysis, and pregnancy tests to rule out specific conditions. Accurate coding requires careful documentation of the patient's symptoms, clinical findings, and any diagnostic tests performed.

Complexity Factors

  • Variety of potential underlying causes
  • Need for thorough documentation of symptoms
  • Differentiation from similar abdominal pain codes
  • Potential for acute vs. chronic pain classification

Audit Risk Factors

  • Inadequate documentation of the clinical findings
  • Failure to specify the nature of the pain (acute vs. chronic)
  • Misclassification of pain location
  • Lack of supporting diagnostic tests
