Is there 15 mg oxycodone

yes ,usually small round green and have a 15 scored on one side and a boxed m on the other they also come in 30 mg's these are same but blue with a 30 on them

this answer is correct, however there are generics for these so the color may not always be the same, as well as the letters and numbers printed on them. you should always search what youre taking before you do.
