Topic: Quick question on correct way to use extension-bodysite
Nath (Nov 09 2020 at 20:29):
in conditions we have extension bodysite to store bodystructure references.
https://www.hl7.org/fhir/condition-definitions.html#Condition.bodySite
condition {
extension : [{
url: <>
valueReference: <body structure ref>
}
]
}
should this be like above or should this be like below
condition {
bodysite: [
extension : [ {
url: <>
valueReference: <body structure ref>
}
]
]
}
which one is correct way to use this extension ?. I searched but unfortunately could not find an example. Could you please kindly clarify?.
thanks

It depends how your body structure extension is defined - does it specify a context of Condition or of Condition.bodySite? (Regardless, you should submit a change request for us to define a 'standard' extension, as there will be lots of systems that will need it.)

we already have: http://build.fhir.org/extension-bodysite.html?
Lloyd McKenzie (Nov 09 2020 at 21:08):
So we do. That one's defined super-generically though - it can appear anywhere (which doesn't really help with standardization...)
Lloyd McKenzie (Nov 09 2020 at 21:08):
Is there a reason it wasn't defined with specific contexts?
Nath (Nov 09 2020 at 21:57):
thanks @Lloyd McKenzie @Eric Haas yes, I am referring to extension-bodysite as well. I am not sure the correct usage of this. would this extension appear inside condition.bodysite or at root level of condition ?. that's the confusion. Looking for an example json with this extension.
@Lloyd McKenzie to answer your question, it's used in the context of condition to refer bodystructure resource.
