actually, ICD-9 is for diagnosis and procedure analysis, CPT is for billing mainly procedures.
there are crosswalks between the two, HCIA sells the CD-ROMs. they are done by year.
I believe AMA holds the CPT copyright.
the recommended way to do the conversion is CPT to ICD-9. but not all in both sets have a corresponding partner in the other.

They're different beasts. There is no mapping.
ICD9 codes are diagnostic codes. CPT-4 codes are treatment codes.
While there is typically a relationship between diagnosis and treatment,
one cannot be determined from the other.
