How to map CPT Category II codes?

Hey everyone, would anyone have any advice on how to handle mapping CPT Category II codes over to tables within the CDM? Specifically, taking a CPT Category II code and determining what its relevant table within CDM is.

I’m dealing with a mishmash of insurance claim data that uses CPT4, CPT Category II, HCPCS codes. I’ve found the SQL crosswalks on GitHub for CPT4 and HCPCS and they work well for my purposes, but I can’t find anything like that for CPT Category II.

Hi,
it’s a good question, actually.
We are currently working on a CPT4 update and we’ll try to put this update having Category II codes into the next OMOP vocabulary release.

Can you, please, give a link to those CPT4 - HCPCS crosswalks?

Ah I see, thank you! Here is the CPT4 SQL script:
‘https://github.com/OHDSI/Vocabulary-v5.0/blob/master/CPT4/load_stage.sql’

and here is the HCPCS SQL script:
‘https://github.com/OHDSI/Vocabulary-v5.0/blob/master/HCPCS/load_stage.sql’

(The forum for some reason wouldn’t allow me to post with the links, hence the quotes)

Thanks, got it.

Yeah, it’s our normal scripts to deal with these vocabularies.
I thought you found crosswalks between HCPCS and CPT4 that’s why I asked.
