CP-1647 Correct SNOMED lesion codes and synonyms Status Assigned Date of Last Update 2016/09/05 Person Assigned David Clunie Submitter Name QIICR Submission Date 2016/08/04 Correction Number CP-1647 Log Summary: Correct SNOMED lesion codes and synonyms Name of Standard PS3.16 Rationale for Correction: Over time various different codes and synonyms have been used in different contexts for the concept of a "lesion" and/or findings about a lesion, and some uses of these uses are now deemed "inappropriate" in SNOMED. Replace uses of M-01000 that have a synonym of "Lesion" (inappropriate synonym in SNOMED) with the preferred name in SNOMED, "Morphologically abnormal structure". Clean up uses of M-01000 that have correct (acceptable) synonyms to use "Morphologically abnormal structure" rather than variants of it. In addition, SNOMED also contains a different code M-01100 (SCT:52988006, UMLS:C0221198), which is "Lesion (morphologic abnormality)", and is a child of M-01000, which is not currently in the DICOM-SNOMED subset but has been requested (SIRS Request ID 710711 Batch ID 710721), and is added to provide support for the more specific concept. (F-03FCD, SRT, "Lesion Finding") is not an appropriate substitute for M-01000, since it refers to the characteristics of lesions, rather than the lesion per se.
