Filing for GERD Increase

Greetings Moto’s, 

I have recently received my C FIle and in review of the C&P I had for GERD.  I was granted service connection and rated at 10%.  Given what I am reading in my C&P exam I think things were not taken into consideration as based on the examiners notes I qualify for a 30% rating. 

What is the best way to go about requesting this increase? 

TIA
