Yes, we did
@Christian_Reich, if you mean relationships to SNOMED, so we didn’t.
We just have hierarchical relationships between ICD10PCS themselves, for example
DT1297 Subsumes DT1297Z
BB0 Subsumes BB08
Hello,
Can anyone let me know that what is “Concept Type Vocabularies”.
where can i find theses vocab as theses are not available at Athena .
I would also to know that how to use and it would be really appreciable if someone can quote some examples.
Is there any vocabulary for location as well??
Thank you.
Is there a plan, work in progress to come up with a single vocabulary hierarchy? Or is one forever cursed with dealing with multiple vocabularies and having to reconcile them?
What do you mean by “vocabulary hierarchy” or “reconciling” vocabularies? ICD-10 is a product of the WHO, and ICD-10-CM a derivative maintained by the CMS, which is part of the US government. Other countries also have their own national versions of ICD-10. These guys just do these things, there is not a lot we can do about that.
An oversimplified example would be character sets. We started with ASCII and now have character sets that can represent any language.
The actual physical conditions, drugs, procedures are the same regardless which vocabulary is used to reference them, so there must be a way to homogenize the codes and therefore the mappings from terms to codes.
Yes, I get your point that different agencies/countries just do their own stuff without regard for consistency.
The motivation for consistency, however, would be to enable building cohorts based on multi-national, multi-agency, multi-institutional data.
You are totally right. That needs to happen. In fact, we have the explicit goal to have a concept for every medical entity there is, and to have only one such standard concept. For Drugs this is more or less already achieved, for Conditions it’s in a good shape (SNOMED does the de-duping work for us), for Measurements we have LOINC doing the same thing, but Devices, Procedures and Observations need work. Want to lend a hand? 
Although I don’t mind doing some work, I’d prefer to not formally commit to it, as I don’t know up front what projects I will be doing.
That said, I’d propose that this should be a crowdsourcing effort similar to Wikipedia, so that multiple people can adjust, modify, add entries in a spreadsheet (documenting rationales for their edits.) Of course with multiple people being able to edit, one needs some version control mechanism. Github could be used? I am not sure if Google docs allow version control or not.
You mentioned several domains that are in reasonable shape, assuming those data are available in machine consumable format, they can be used to initialize the spreadsheets.
For procedures, devices, observations people in the know could probably identify the most consistent source with most coverage to get the ball rolling.
But that’s how it works here: You collect a bunch of like-minded people and start working in a shared environment. Apart from Maura, the PM, all of us have day jobs, which sometimes have the tendency to distract us from the fun, here. 
So, feel free to chime right in. You seem to have a lot of ideas.
@Christian_Reich, could you explain in more detail what your effort (the one to be finished in January) is?
Are you mapping ICD-10-CM (at least the 50k ones that are only in ICD-10-CM) codes to ICD-10 codes?
Is it text similarity based? Is it being done manually?
All roads are leading to Rome, meaning, everything gets mapped to standard concepts. For conditions (ICDs have mostly conditions, but note the “mostly”) those are derived from SNOMED, and most of them are “Clinical findings”. So, ICD-10 and ICD-10-CM is going to be mapped to SNOMED. But: We need to make sure that the mapping is consistent. Not necessarily identical (the detailed meaning of the same code in ICD-10 and ICD-10-CM might differ slightly), but consistent.
