Ask Dr. Z

Is radiofrequency for nerve localization a billable procedure? Or would it be included in the nerve block with imaging guidance procedure? If billable, would this be unlisted code 64999, comparable to a pulsed RFA procedure?

"Indications: The patient's history and physical findings include pain consistent with ilioinguinal neuralgia. The patient is here for left ilioinguinal nerve block with radiofrequency neurostimulation.

A 22 gauge 54 mm curved sharp RF cannula was inserted percutaneously and advanced under ultrasound guidance using linear probe with medial to lateral approach to the target nerve. No paresthesias occurred, and aspiration was negative. Radiofrequency neurostimulation was used to assist with nerve localization. The nerve(s) were then stimulated at 42 degrees C at 20 msec pulse width and 2 Hz for 6 minutes, then a nerve block was performed by injection of Dexamethasone (10mg/mL) 5 mg and Bupivacaine (0.5%) 8 mL."
