ICD Code R19.09

ICD code R19.09 is used to indicate the presence of an unspecified swelling, mass, or lump within the abdomen or pelvic region that does not fit into more specific diagnostic categories.

1. Presence of a palpable swelling, mass, or lump within the abdominal or pelvic cavity

3. Imaging studies (e.g., ultrasound, CT, MRI) confirm intra-abdominal or pelvic mass without clear etiology

4. Patient may present with symptoms such as abdominal discomfort, bloating, or visible distention

5. No evidence of hernia, organomegaly, or localized abscess as the primary cause

6. Mass or swelling is not associated with pregnancy or gynecological conditions with specific codes

7. Clinical evaluation and laboratory findings do not indicate infection, malignancy, or inflammatory disease as the primary diagnosis

8. The finding is incidental or unexplained after initial diagnostic workup
