    Default Chiari I Malformation ICD-9 Code

    All I can come up with a dx code for Chiari I Malformation is 741.00. Does anyone have any other/better suggestions. This is on an 80 year old woman. Thanks for your input.

    For Type I, use 348.4. 741.x and 742.x are for Type II, III and IV.

    If you look at the Index in your ICD-9-CM book under Malformation, go to Chiari. It lists for you type 1-4 and the respective codes. Always be sure to verify in the Tabular List. If you're unfamiliar with what Chiari Malformation type I is you may have to do some more research but I can tell you that gost is correct in his/her code selection. Hope this helps!

    Question Chiari syndrome NOS

    What if the doctor does not specify the type, should we go with the type 1 code or can we not code it at all? I do risk adjustment coding and I have no way to contact the provider.

    What if they do not list a type 1-4. Just says chiari malformation. Is there is a default or can you not code it without a type?
