What type of service code should be used with 97597 and 97598

I'm in the process of setting up our system for the 2011 changes and I'm not sure what type of service code to use for debridement codes 97597 and 97598. I'm thinking "9", but would like your input.

Service Type "9"???

How does your system define a service type code of "9"?
