In Australia we are now using ICD-10 AM (Australian Modification) version 4 for the development of DRGs and hospital WEIS payments for which I do have a fair bit of the Podiatry related codes, but there was a substantial changge between 9 and 10.
I did however find this site

That provides free online searching of the ICD 9
