Can anyone offer any insight on billing injections for Aetna with 20611 for ultrasound guidance? Aetna denies 20611 every time per their policy that it's experimental. We have had some success with medical necessity on appeals, but Aetna Medicare has been denying this as well. Our sports medicine physician only does Orthovisc/Euflexxa injections with ultrasound. We are considering the option of billing the J code for the drug to Aetna and making the administration code self pay for the patient. Does anyone have any experience with this?
