Skin picking

Is there perhaps a separate rating for numerous scar related to skin picking…I have a bad skin picking problem (numerous scars on my hands, face and limbs) that cause scarring and constant bleeding. I’m seeing therapist through VA community care and we’ve been working on it but it hasn’t gotten better. Just wondering if I should file an increase for my PTSD to try and go from 50-70 percent (idk if I fit the 70 percent criteria but with this maybe being considered self harm I might? ) or is there seperate rating for this condition/ scars?

Has anyone got a rating or an increase for skin picking?
