About the 0CL Code Range
These procedures completely close the opening or inner passage of a parotid duct on the right or left side.
The fourth character identifies the right or left duct. The fifth describes access: open exposure, a puncture or small incision with or without a scope, or entry through a natural or artificial opening with or without a scope. The sixth distinguishes a device outside the passage, a device inside it, or no device. The seventh is always No Qualifier.
