    Modifier: CMPX

    COMPLEX TIME

    This modifier type is used to indicate a complex patient visit payable in time units by general practitioners only.

    AMA billing tips:

    • When claiming a procedure and a visit service at the same encounter, the time spent completing the procedure cannot be used to calculate the time for complex modifiers (CMGP, CMXV, CMXC). For example, a patient might ask a physician to examine a sebaceous cyst, and the physician decides to excise the cyst.

      If the time spent examining the cyst was under 15 minutes, and the time removing the cyst took 25 minutes, the claim to the Alberta Health Care Insurance Plan could look like: 03.03A and 98.12C.

      The complexity modifier could not be claimed, as the time spent delivering the visit portion of the service was under 15 minutes.
