Furuncle unspecified hand

This code represents a localized, painful bacterial infection of a hair follicle and surrounding skin, forming a pus-filled nodule, located on an unspecified part of the hand. It is a type of skin abscess caused by Staphylococcus aureus bacteria.

Use this code when documentation specifies a furuncle on the hand without further detail regarding the specific digit or area (e.g., palm, dorsum, finger). This code is appropriate when the physician's notes clearly identify a furuncle and its location on the hand, but lack greater anatomical specificity.

• Do not use this code if the documentation specifies a particular finger or other distinct anatomical site on the hand; instead, look for a more specific code.
• Ensure the documentation clearly differentiates a furuncle from other skin infections like cellulitis or carbuncles.
• Consider an additional code for the causative organism (e.g., B95.61 for MRSA) if identified and documented.
