The word lesion can be used to refer to both structural and functional abnormalities. This makes a subtle distinction between the clinical finding and disorder semantic tags. The majority of lesions in SNOMED CT are in the disorder subhierarchy.
Lesion as a disorder
If a concept refers to a lesion that is a structural abnormality, then apply the (disorder) semantic tag, and model with an 116676008 |Associated morphology (attribute)| of << 52988006 | Lesion (morphologic abnormality)| .
If a procedure refers to a lesion that is a structural abnormality, then model with a 405816004 |Procedure morphology (attribute)| of << 52988006 | Lesion (morphologic abnormality)| .
Lesion as a finding
Lesion concepts referencing characteristics of a lesion are subtypes of 300577008 |Finding of lesion (finding)|.
Imaging-related lesion findings remain as finding concepts.
Functional lesions should not be modeled using values from the 52988006 |Lesion (morphologic abnormality)| subhierarchy.
