Localized swelling, mass and lump, head

This code signifies a palpable, circumscribed enlargement or protuberance located specifically on the head. It represents a non-specific finding that requires further investigation to determine the underlying etiology. This code does not indicate the cause of the swelling, mass, or lump.

Use this code when documentation indicates a localized swelling, mass, or lump on the head without further specification of its nature or definitive diagnosis. This is appropriate for initial encounters where the provider is still evaluating the finding, or when the specific diagnosis remains unknown. Documentation should clearly state the presence and location of the finding on the head.

• Do not use this code if a more specific diagnosis for the head mass/lump is known (e.g., sebaceous cyst, lipoma, tumor).
• Always sequence this code as a secondary diagnosis if the underlying cause is identified and coded.
• Ensure the documentation specifies "head" as the anatomical location; otherwise, a more general R22 code may be appropriate.
