I am in Texas and I have billed a joint injection to medicare as 20610 1 unit but I double the price with a 50 modifer and J7325 32 units with dx: M17.0 on both CPT codes and I keep getting denials stating not medically necessary. I do not understand what I am doing wrong. Provider injected both knees. Normally he does 20610 (1) UNIT AND J7325 (16) UNITS for one knee but one this patient he decided to do bilateral.
