ICD-9 Coding: 700 Basics: Simplify Corn and Callus Coding

Learn what to do when these lesser-known terms show up in your doctor's documentation?

For dermatologists who are treating the skin of a patient's foot, one of the most generally coded diagnoses is corns (and calluses). This particular condition has a slew of puzzling names that may be difficult to find -- or may not be present in your ICD-9 coding book -- and could quickly overturn your claims.

Decoding all of the corn and callus terminology can be particularly complex in case you work for numerous physicians and each one has his own particular way of naming the same thing, or in case you've lately started working at another practice. But you no longer have to be ignorant as far as a callus-related term is concerned.

Watch out: "Tylosis" could lead you down the erroneous coding path if you're not cautious. The ICD-9 index present in the front of the coding book presents numerous options, for instance 757.39 (Other specified amomalies of skin; other; includes accessory skin tags, congenital; congenital scar; epidermolysis bullosa; keratoderma [congenital]), and this is the incorrect path for a basic corn or callus. The best way you encounter this particular term present in the documentation is to ask the dermatologist to explain the condition.

ICD-10: Once ICD-9 changes to ICD-10 in October, 2013, code 700 become invalid. In its place, you would report ICD-10 code L84 (Corns and callosities).

Ace the Definitions

In case you're still uncertain about your dermatologist's everyday explanation of these general conditions, learning the definitions of "corn" and "callus" will help. Remember, a corn is a small, horny area of the skin produced by local pressure (e.g., a shoe or hosiery) irritating the tissue over a bony prominence.

Corns normally takes place on a toe, where they form "hard corns." (Between the toes, pressure can form a soft corn of macerated skin, which often yellows.)

Moreover, a callus is localized thickening and enlargement of the horny layer of the skin because of pressure or friction. Normally, calluses as well as corns can result in pain, and soft-tissue inflammation may take place around the base of the lesion.

Knowing these definitions is also supportive in case you plan to ask the dermatologist for explanation.

For instance: You're struggling with how you should code a patient diagnosis that defines a "keratosis" of the bottom of the great toe and the heel. You've learned the synonyms for corns/calluses and recall that this is one more name for a callus, however you notice that a different nearby code has the identical word in its descriptor: 701.1 (Keratoderma, acquired; Keratosis [blennorrhagica]).

For an error-free ICD-9 coding , you request the dermatologist for more particulars about the patient's condition so you can code it correctly, and he defines a basic thickening of the skin owing to bad shoes. After studying the definitions, now you know that it's just a callus and you can further code it as 700.
