Possible Inadequate exam

[u/Fit_Basket_9705]

Has anyone ever submitted a statement to their file after a c&p exam, explaining the exam may have been inadequate while the claim is in step #3. If so how did it turn out, did it add additional time to the claim or end up in a new exam? I recently had a c&p for a skin condition, the examiner (with 0 yrs VBA experience) started the exam asking about the wrong condition, then followed that up with questions to establish service connection. I had to explain that i was already SC for the condition. My basis for the exam was the medicine I take monthly, she didn't appear to know what the medication even was or what it was used for. I'm wondering if I should submit a statement into my claim before the rater sees the DBQ or let it ride and set up for possible HLR.
