There are four bones in the thumb. one at the top one at the bottom and one at either side.The bones in the thumb consist of: distal phalanx; proximal phalanx; metacarpal; carpal bones (carpometacarpal joint (CM).
The carpometacarpal joint of the thumb is a saddle joint. It makes the thumb opposable allowing us to manipulate tools and to grip.
The code I would use is 20600.
I have the same issue on both wrists and doctor is recommending joint replacement surgery. Medicines, therapy are all temporary band-aids and will not fix the problem.
