What is the use of modifier -Q6 in coding?

Using modifier -Q6 pertains specifically to services that are provided by a locum tenens physician, which means a physician who temporarily substitutes for another physician. This modifier is utilized when a physician, who is typically not the patient’s regular provider, conducts a service under specific conditions. In many healthcare settings, this is essential for ensuring that patients continue to receive care, especially when their primary physician is unavailable due to reasons such as vacation or medical leave.

For medical coding purposes, applying the modifier -Q6 indicates that the service is rendered under the supervision of another physician, allowing the temporary or substitute physician to perform necessary medical procedures or evaluations while adhering to the healthcare facility's policies and regulatory requirements.

The other choices do not accurately capture the essence of modifier -Q6. While they encompass various scenarios within healthcare coding, they do not pertain to the locum tenens context where this modifier is specifically applicable.
