Wiki Descent of Cerebellar Tonsils

[klamm]

Does anyone know what Dx code to use for "worsening of the descent of cerebellar tonsils"? The medhelp.org forum suggests that this is another term for Chiari Malformation. I wanted to get some confirmation before I used this diagnosis.

Anyone's help is greatly appreciated

Yes, that is correct. There are 4 types...look up Chiari malformation in the ICD-9 CM index, that should get you on the right track. Also, here's the link to an earlier AAPC forum thread that you may find helpful.
