    Default excision of toe callosity

    AAPC: Back to School
    Patient had an excision of rt small toe callosity with also an excision of exostosis off of a toe phalanx .

    any ideas what code(s) this would be ?

    doc stated an incision was made in elliptical fashion over the callosity of the small toe. This was excised without difficulty. The exosostosis was identified. A small rongeur and rasp was used to debride tje exososis down to the stable base. The wound was irrigated and closure with a 3-0 Vicryl suture fllowed by 4-0 nylon suture superficially. Soft dreesings was applied

    Callosity is a thickening /hyperkeratosis of the skin (overlying the bony region) , due to intermittent pressure effect and friction episodes. It is otherwise known as clavus of the skin( dermatological lesion).
    Exostosis is like bossing of the bone more or like a bony sequestrum but with some histological difference and deposits of lipid material on to it.
    The excision of the callus could be reported from the Integumentary Category -like 11055-11057 with modifier-59.

    The exostosis /bossing excision is like partial excision(craterization, saucerization /sequestrectomy) and may be reported with 2812x series ; in your can be appropriated with 28124. (as the first listed CPT code)
    [there is a term callosity or callous formation with respect to the bone , but it is not pathological; it is a physiological healing process in the bone during fracture healing. We should not misinterpret it to this callus of your case]
    I hope it gives you some clues
