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.
 
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!
 
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?
