Furuncle of groin

This code signifies a localized, painful bacterial infection of a hair follicle and surrounding skin, specifically located in the groin region. It presents as a tender, red nodule that typically develops a pus-filled core.

Apply this code when documentation clearly indicates a furuncle (boil) affecting the patient's groin area. Supporting documentation should specify the location and confirm the diagnosis of a furuncle.

• Differentiate from carbuncles, which are deeper and involve multiple hair follicles.
• Ensure documentation specifies "groin" as the anatomical site; avoid using for other body areas.
• Consider an additional code for the causative organism if identified and documented (e.g., Staphylococcus aureus).
