[bioontology-support] [BioPortal] Feedback from Lori Phillips

Hi,

As you may know, ICD10 PCS is a multi-axial coding system [1]. The “@“ symbol separates values from different axes. "Medical and Surgical @ Central Nervous System @ Bypass” tells you that it’s a class of procedures in the “Medical and Surgical” section, operating in the "Body System" Central Nervous System, using the Bypass “Operation.” The names with “@“ separators are like SNOMED CT’s fully specified names, and correspond directly to the underlying ICD10 PCS codes.

If you search for ICD10 PCS terms in the UML Metathesaurus browser, you’ll see these “@“-separated terms.

With best regards,
Samson

Feedback:

Question on ICD10 PCS.
Preferred names contain hierarchy such as
"Medical and Surgical @ Central Nervous System @ Bypass"
In this particular case the synonym seems like a better alternative:
Central Nervous System , Bypass.
Any idea why the preferred name has all the '@' delimiters?
On i2b2, the long names are cumbersome especially at the lower levels so I have been stripping the name to the string after the last '@'. For this case that == equals Bypass, which isnt too informative by itself .. the synonym is better. Did UMLS really specify it this way?
