Preserving third-party claim system codes in generated typelists

PolicyCenter uses the source system category properties of codes in ClaimCenter typelists to determine the origin of the codes. A value of PC indicates ClaimCenter codes that originate in PolicyCenter. The ClaimCenter Typelist Generator adds, changes, or deletes only codes that originate in PolicyCenter.

Any value for source system category other than PC, including the absence of a source system category, indicates ClaimCenter codes that originate somewhere other than PolicyCenter. Those typecodes pass through the generator unchanged from input to output.
