About the condition

Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.

Sarcoidosis

Sarcoidosis is a condition in which groups of cells in your immune system form small, red, and swollen (inflamed) lumps. These lumps are called granulomas. They can form in any organ in the body. But they most commonly affect the lungs and lymph nodes in the chest. Over time, sarcoidosis can cause permanent scarring of organs.
