Reporting Resources

• CODES Technical Meeting 2003 Presentation: Diagnosis and Procedure Code Grouping Schemes gives an overview of various diagnosis and procedure code grouping schemes. It also examines using principal diagnosis versus multiple diagnoses when reporting injury data. Presentation developed by Betty Harris, Oklahoma CODES Project.
   
• The Barell Injury Diagnosis Matrix, Classification by Body Region and Nature of the Injury is a product of the International Collaborative Effort Injury Statistics. This classification scheme codes injury diagnoses into categories based on type and nature of injury. The CDC website has a link to SAS code that derives the Barell categories. Suning Cao, Iowa Center for Health Statistics modified the CDC SAS Code using Array statements to define 10 diagnosis fields in one data step. A translation table has also been developed for use in MS Access. To obtain a copy, e-mail Bettyh@ou.edu.
   
• The Agency for Healthcare Research and Quality (AHRQ) Healthcare Cost and Utilization Project, Clinical Classification System Categories can also be used to group both diagnosis and procedure codes.
  • The single-level diagnosis CCS aggregates illnesses and conditions into 259 mutually exclusive categories.
  • The single-level procedure CCS aggregates procedures into 231 mutually exclusive categories, most representing single types of procedures.
  • The multi-level CCS expands the single-level CCS diagnosis and procedure code groups into a hierarchical system.
