Peroneal Tendoscopy and Malleolar Osteotomy via Arthroscopy

[such78]

1>Is there any specified CPT code for the peroneal tendoscopy, or use unlisted CPT code?
2> Which code(s) I use for arthroscopy left ankle lateral and medial malleolar osteotomy ( dx: lateral malleolar tip osteophyte and medial malleolar tip osteophyte)?

Thanks in advance.

1. For the peroneal tendoscopy, I would use unlisted code.
2. For the arthroscopy, I would use 29898, as it includes bone spur removal
