Left upper quadrant abdominal swelling, mass and lump

This code signifies the presence of an abnormal swelling, mass, or palpable lump located specifically in the left upper quadrant of the abdomen. It indicates a physical finding that requires further investigation to determine its underlying etiology. This is a symptom code, not a definitive diagnosis.

Use this code when documentation clearly indicates a patient presents with a palpable mass, swelling, or lump confined to the left upper abdominal region, and a more specific diagnosis has not yet been established. This is appropriate for initial encounters or when the cause of the abdominal finding is still under investigation. Supporting documentation would include physical exam findings, patient complaints, or imaging reports noting a left upper quadrant abnormality.

• Always attempt to code to a more specific diagnosis once known (e.g., splenomegaly, gastric mass, pancreatic cyst).
• Do not use this code if the mass is generalized or located in a different abdominal quadrant.
• Consider sequencing this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it's an associated finding.
