Evidence information
When reviewing the criteria, useful evidence categories can include diagnosis and treatment records, objective testing identified by the schedule, documented frequency/duration/severity when the criteria use those concepts, and functional effects described in medical or lay evidence. The relevant evidence depends on the actual claim and medical facts.
VMC does not diagnose conditions, guarantee a percentage, or advise anyone to exaggerate symptoms.
