When medically directing two anesthesia cases, which modifier should the anesthesiologist use?

In the context of anesthesia coding and billing, when an anesthesiologist is medically directing two anesthesia cases, the appropriate modifier to use is QK. This modifier indicates that the anesthesiologist is providing medical direction for certified registered nurse anesthetists (CRNAs) or physician’s assistants (PAs) during the anesthesia procedures.

The use of QK specifically denotes medical direction for two concurrent cases, which is critical for accurately capturing the level of service and reimbursement in the context of anesthesia management. Each case must also meet certain conditions, such as the anesthesiologist being present for the critical parts of the procedure and the ability to supervise and direct the anesthetic care effectively.

Employing the QK modifier communicates to payers that the anesthesiologist is managing multiple cases and is actively involved in directing the anesthesia provider's services. This is essential for ensuring proper compensation and adhering to the regulations governing anesthesia practices.
