Injection denial

Best answers
I'm wondering if anyone can help me or give me some thoughts. I have a patient that had pes bursitis, lateral deltoid insertion tendinitis and biceps tendinitis. All on the right side. This was done in 2015 so it's ICD9. For the injections, i put 20610 RT (726.61), 20550 59 RT (726.12), and 20551 59 RT (726.19). The note specifically says that the deltoid insertion was injected which is why I used 20551 and the biceps tendon I use 20550. I wrote an appeal and sent the documentation. In the appeal I stated that they were three completely different areas/injections and that we should get payment. This 2nd level appeal I'm writing brings up the fact that the LCD list even supports the DX codes & CPT codes. It also brings up the guidelines stating that if they were into the same tendon sheath/ origin then I would only charge for one injection. These are two different ones (as if the names of both weren't enough). I just don't know if i'm missing something or what. Payer is UHC.

Thank you!
