Can someone tell me - does the anesthesia modifier AD have any effect on reimbursement?

Per American Society of Anesthesiologists, "Anesthesia Payment Basics Series: #3 Anesthesia Modifiers and Payment Determination", August 2019
Modifier AD: Medical Supervision by a physician; more than 4 concurrent anesthesia procedures
Medical supervision occurs when the anesthesiologist is:
-involved in more than four (4) concurrent anesthesia services, or
-performs other services while directing anesthesia care.
Medicare contractors allow three (3) base units for medical supervision of anesthesia care with one additional unit if documentation demonstrates that the anesthesiologist was present during induction.

CMS's transmittal is: R2716CP - CMS Manual System

I hope these references help. Take care and stay safe.

Thank you so much for the reply. So the 3 (sometimes 4) units that are allowed for the modifier are added to the units for the anesthesia cpt itself?
