ICD-10 Code L92.3 – Foreign body granuloma of the skin and subcutaneous tissue (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L92.3 – Foreign body granuloma of the skin and subcutaneous tissue
What it is
L92.3 identifies a granulomatous reaction in the skin or subcutaneous tissue caused by a retained foreign material. It is used when the body forms an inflammatory nodule around an embedded object.
Clinical signs
Typical findings include a firm, localized skin nodule, swelling, redness, or tenderness at the site of prior injury or penetration. Clinical features vary; refer to documentation.
When to use this code
Use L92.3 when documentation states a foreign body granuloma in the skin or subcutaneous tissue, such as after a splinter, glass fragment, or other retained material. Code it when the diagnosis is confirmed and the lesion is not being described only as a simple wound or abscess. If the record does not clearly identify a foreign body reaction, check documentation before assigning this code.
Do not use for
Do not use this code for a retained foreign body without granuloma, or for superficial skin irritation alone. Check documentation if the condition is instead an acute wound, infection, or another specific skin lesion.
Coding tip
Link the code to documentation of both the foreign material and the granulomatous reaction, not just the injury history.
