Excision of mass left small finger, left carpal tunnel release

How would you code this? I am reading mucoid degeneration and he keeps extending the incision, but I don't think an actual cyst was removed. The carpal tunnel was not planned, can I bill it with the cyst excision 26160 or should I bill the arthrotomy with exploration 26070-26080?


Preoperative diagnosis: Left small finger mass
Postoperative diagnosis: Same
Operation performed: Excision of mass left small finger, left carpal tunnel release
Anesthesia: Block converted to general

Indications...
