IMO
A formal written opinion from a private physician (not the VA) providing an expert medical assessment of the nature, cause, or severity of a disability — used to support VA disability claims and appeals.
An IMO typically addresses nexus (service connection), severity, or the relationship between conditions. Must use the 'at least as likely as not' standard (50%+ probability) to be persuasive to the VA.
IMOs carry significant weight in VA appeals when they contradict a negative C&P exam finding.
Cost: typically $500–$2,500+ depending on specialty and complexity.
→ An IMO from a specialist in the relevant field (neurologist for TBI, psychiatrist for PTSD) carries the most weight.
