    AAPC: Back to School
    Patient had a history of injury to the thumb ulnar collateral ligament. Patient had an unstable MCP joint and elected to have surgery to repair left thumb ulnar collateral ligament. WoulD cpt CODE 26540 be the correct code ?

    DX code 841.1 is not correct for THUMB collateral ligament sprain. This code (841.1) pertains to the elbow and forearm/wrist area. For a sprain of the thumb, look at which joint is noted in the OP Note. For a metacarpophalangeal joint ulnar collateral ligament sprain, you would use code 842.12.
