They do, primarily for inpatient procedures. I think it's once again because of it's original purpose. If you want to classify causes of death, and someone dies because of a procedure done in the hospital, they would like to capture that data. Outpatient procedures (hopefully) are less likely to result in mortality so the usefulness of including them decreases. CPT is used for billing, so it captures procedures for very different reasons.
Here is the 'official' purpose of ICD-9-CM: "The International Classification of Diseases, Clinical Modification (ICD-9-CM) is used to code and classify morbidity data from the inpatient and outpatient records, physician offices, and most National Center for Health Statistics (NCHS) surveys." Because it serves a different purpose, any attempts at linking the two together would also be governed by the purpose for which those links would be used. Associating every possible connection may or not be useful/helpful depending on what they want to use them for. I tend to forget about the procedure ICD-9-CM codes because they aren't used by the software I work on. At least not yet. I didn't mean to spread confusion. I hope the rest of my points remain valid.
