    Default Please, need help with ICD-10

    AAPC: Back to School
    I know that if three digit category has no further subdivision I can bill this three digit category as code. So if there are further subdivisions should I use code only from these subdivisions ? For example:
    L71 Rosacea
    L71.0 Perioral dermatitis
    L71.1 Rhinophyma
    L71.8 Other rosacea
    L71.9 Rosacea, unspecified

    In this case I cannot bill L71, right? Or it is not mandatory to bill extended code and I still can use L71?

    Thank you.

    From what I understand, that part of the coding conventions will not change - if there are additional digits available, you use them. The first three are your category; 4, 5 and 6 are etiology, anatomical site, and severity; 7 is the extension. If the additional digits are available, you use them. One big difference is, let's say a code has a 7th character that must be used, but no 5th and 6th; you would use x as a place holder to add that 7th.

    So, with the codes you are referencing, L71 is the category; since there are 4th characters, you would use one of them.

    Hope this helps.

    I have a question regarding ICD-9-CM coding.
    If the assessment states: Rheumatoid arthritis with multiple joint involvement, stable (714.0)

    then it states: With current conditions, hypertension may develop.

    We we code "hypertension may develop"?

    Default "impending hypertension"

    I don't think you can code a condition that isn't yet confirmed to be present, so your "hypertension may develop" can't be coded. This would be in a report so that other providers the patient might see will know to check for it.
