Code Description

ICD-10 R10.12 is a billable code used to indicate a diagnosis of left upper quadrant pain.

Key Diagnostic Point:

Left upper quadrant (LUQ) pain refers to discomfort or pain located in the upper left section of the abdomen, which can arise from various underlying conditions. This region houses several vital organs, including the stomach, spleen, left kidney, pancreas, and parts of the colon. Symptoms may vary from sharp, stabbing pain to dull, persistent discomfort. Patients may also report associated symptoms such as nausea, vomiting, fever, or changes in bowel habits. Common causes of LUQ pain include gastrointestinal issues like gastritis, peptic ulcers, or splenic disorders, as well as renal conditions such as nephrolithiasis. In some cases, LUQ pain may indicate more serious conditions like myocardial infarction or splenic rupture. A thorough clinical evaluation, including a detailed history and physical examination, is essential to determine the underlying cause. Diagnostic imaging, such as ultrasound or CT scans, may be warranted to assess the organs in this region. Laboratory tests may also be performed to evaluate for signs of infection or inflammation.
