Localized swelling, mass and lump, trunk

This code signifies a palpable, circumscribed abnormal growth or enlargement located on the torso, excluding internal abdominal or pelvic structures and breast tissue. It represents a non-specific finding that requires further investigation to determine its etiology.

Assign this code when documentation describes a patient presenting with a localized swelling, mass, or lump on the back, chest wall, abdomen (superficial), flank, or perineum. This code is appropriate when the provider has not yet determined a definitive diagnosis for the mass.

• Do not use this code for masses clearly documented as originating from internal abdominal or pelvic organs.
• Always query the provider for a more specific diagnosis if available, as this is a symptom code.
• Ensure the documentation specifies the trunk as the location; avoid using for extremities or head/neck.
