Hi, I am hoping someone can help us, as we just had an orthopaedic practice join our group.

Our provider applied a dorsal aluminum splint for his patient, for tenosynovitis of the left small finger. He submitted the code A4570, which was denied by the insurance carrier. Another coder suggested trying S8450 or Q4049 instead. Can anyone tell me which code you would use for this service, and what the difference is between the three codes?

Thank you!
