One of our Urologists are inquiring about this…….He states that if he does a renal and ureteral ESWL (Lithotripsy - 50590) using different/separate diagnosis codes because of different organs (renal and ureteral) but both ESWL's would be done on the right side. Can he bill for 2 ESWL's on the right or is it right and left only?

Can you offer any insight?
