Descent of Cerebellar Tonsils

    Question Descent of Cerebellar Tonsils
    Medical Coding Books
    Does anyone know what Dx code to use for "worsening of the descent of cerebellar tonsils"? The 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.
