Surgeon performs open repair of severe comminuted fracture of distal radius and ulna. He uses cancellous cadaveric bone to pack and elevate the fragments (5) in order to place the fixation hardware. Surgeon billed 25575. Facility billed 25609 and 25999. Is the unlisted code appropriate? Does the allograft fall under the description of "internal fixation"?
I've been all over the place researching and can't come up with an answer.
Thank you!
