Code Description

ICD-10 R10.30 is a billable code used to indicate a diagnosis of lower abdominal pain, unspecified.

Key Diagnostic Point:

Lower abdominal pain, unspecified (ICD-10 code R10.30) refers to pain located in the lower abdomen without a specified cause. This symptom can arise from various underlying conditions affecting the gastrointestinal, urinary, reproductive, or musculoskeletal systems. Common causes include appendicitis, diverticulitis, urinary tract infections, ovarian cysts, and pelvic inflammatory disease. The pain may be acute or chronic and can vary in intensity. Patients may present with additional symptoms such as nausea, vomiting, changes in bowel habits, or urinary symptoms, which can aid in diagnosis. Clinical evaluation often involves a thorough history, physical examination, and may include imaging studies or laboratory tests to identify the underlying cause. Accurate coding requires careful documentation of the patient's symptoms and any relevant findings to ensure appropriate treatment and billing.
