Is 117054005 |Prothrombin time inverse ratio (procedure)| a valid concept? We cannot find a strong reference for it. LOINC includes "Prothrombin time inverse ratio" as a related name of "Prothrombin index"(https://loinc.org/6302-4/). It also appears as a related name associated with an inactive LOINC Term (http://www.hipaaspace.com/medical_billing/coding/logical.observation.identifiers.names.and.codes/5896-5).

Daniel Karlsson I had posted the above question a couple of months ago and haven't received a response. Could we add it as an agenda item for our next OIMP call? There is a request to inactivate this concept. Thanks, Suzanne
