CPT (Current Procedural Terminology) and ICD9 (International
Classification of Diseases) are different coding systems, for
different purposes. Is your intention to convert some CPT procedure
codes into some kind of ICD-9-CM procedural equivalent? Such
conversion maps are proprietary and expensive (not to mention: highly
depending on the setting and goals of the analysis) and would not be a
standard part of a broad-use statistical software such as Stata. One
example is the Clinical Classifications Software for Services and
Procedures developed by the Agency for Healthcare Research and
If you want to construct such a dictionary for your specific purpose,
you may find the built-in ICD9 dictionary in Stata helpful (-help
