Surgical removal of half or more of the penis.
The key fact VA needs to confirm for this rating is that half or more of the penis has been removed. Operative reports, surgical records, and pathology reports from the procedure are the most direct evidence of this. A physical examination documenting the extent of the removal also supports the finding. Discharge summaries or treatment records from the facility where the surgery was performed can help establish the same facts.
If you are also seeking special monthly compensation for loss of a creative organ, records showing the nature and extent of the loss — such as the same surgical and post-operative documentation — are relevant to that determination as well. Statements from you describing how the removal affects your daily life may provide context, though the rating itself turns on the documented extent of tissue removed rather than on functional symptoms.
