​Q:  Would you please explain the difference between a hemiarthroplasty and prosthetic replacement?
A:  A hemi would only be one component, whereas a total would be two components.

Q:  Please provide your reference for your measurements.  The AMA stated measurements are not in the code description.  Who is saying you need to remove 1 cm?
A:  Per the AAOS, “It also is appropriate to code separately for excision of the distal clavicle, if this is done in either an open or arthroscopic procedure. This means excision of the entire distal clavicle (approximately 1 cm), not merely shaving off osteophytes at the acromioclavicular joint. The code for the open procedure is 23120; use 29824 for an arthroscopic procedure.” April 04 Bulletin

Q:  Please clarify SAD performed only= Do you code 29822 only or 29822+29826?
A:  When an SAD is the only procedure performed, you would capture with 29822.  There is a CPT assist referenced in the presentation to support this guidance.

Q:  When Mary talked about a "reversed" shoulder procedure, did she mean "revision"?
A:  There is a procedure referred to as a “reverse” total shoulder.

Q:  What is the code for a reversed total shoulder?
A:  A reversed total shoulder is coded the same way as the normal total shoulder.  The only difference is what it looks like in the anatomy.
