Furuncle right hand

This code signifies a localized, painful, pus-filled inflammatory lesion of a hair follicle and surrounding tissue, specifically located on the patient's right hand. It represents a bacterial infection, typically staphylococcal, that has formed an abscess.

Apply this code when documentation clearly indicates a furuncle (boil) present on the right hand. This diagnosis is supported by physician notes describing a tender, erythematous, nodular lesion with a central core of pus on the specified anatomical site.

• Ensure laterality is explicitly documented (right vs. left hand).
• Distinguish from carbuncles, which are deeper and involve multiple hair follicles.
• Do not use for cellulitis or abscesses not originating from a hair follicle.
