Wiki HCPCS code for Lidocaine

If it is with another drug ( eg. Kenalog) then it is included and you can't bill it separately.

If it is only Lidocaine, then I would go with the unlisted code.
The lidocaine is being give to provide some comfort from the discomfort of the kenalog. It is not therapeutic to the patient's condition. also the HCPC code for lidocaine is IV only. The Kenalog could be given without the addition of the lidocaine, it would just be extremely uncomfortable for the patient.
