Swelling, mass, or lump in chest

This code signifies the presence of a palpable, abnormal enlargement or localized collection of tissue within the thoracic region. It represents a non-specific finding that requires further investigation to determine the underlying etiology.

Use this code when documentation indicates a patient presents with a chief complaint or physical exam finding of a chest swelling, mass, or lump, and a more specific diagnosis has not yet been established. It is appropriate for initial encounters or when the definitive cause is unknown.

• This is a symptom code; always strive for a more definitive diagnosis if available.
• Do not use if the mass is clearly identified as a specific anatomical structure (e.g., breast lump, lymphadenopathy).
• Sequence as a primary diagnosis when the mass is the reason for the encounter, or as a secondary diagnosis if it's an incidental finding being evaluated.
