Medical History - Surgical and Test Procedures

These data are included in the BLSA Common Data Set and are updated quarterly.

There are usually multiple observations for every BLSA participant.

The following are the codes (proccode) for both the Surgical and Test Procedures that were part of the Procedure Name prior to October, 1999. They have not been implemented as SAS formats because their meaning is dependent on the value of Procedure Type (proctyp).
