    Default cmc fracture

    I would look at your radiology report and see what bone was fractured. Was it one of the carpal bones, or was it the metacarpal bone, or both. Was this a traumatic (814-815), pathologic or stress fracture (733.1-733.99)?

    If the injection was for symptoms from the healing CMC fracture, I would code out the symptom and the appropriate aftercare code v54.0-v54.9.

    As for the injection, my opinion is a CMC joint is a small joint 20600, were as the joint of the radius and the carpal bones would be an intermediate joint 20605.

    Hope this helps.

    Look @ 833.04 closed or 833.14 open for joint dislocation CMC and check your documentation to see if it was a dislocated joint and/or a carpal and/or a metacarpal bone. I agree with 20600 for the CMC injection code.
