trying to understand the diffrence
how would this case be coded for a neurostimulator implant:
"then coordinated a very purposeful position and prep. All pressure points were padded. We carefully shaved the patient approximately 2 to 3 cm above the hairline and along the posterior occipital region, until the occipital ridge was exposed and she was clean-shaven. Her front hairline was not shaved. The endotracheal tube was stabilized and secured by the anesthesiologist. The patient’s eyes were carefully sealed with pads and covered with a Tegaderm™ dressing. The entire face was covered with an occlusive Tegaderm™ dressing and sealed. The patient was placed in the lawn chair position under general anesthesia, and with an assistant, her head was lifted gently forward in an anatomical position. I carefully examined and marked the patient. We carefully marked all anatomy, the midline, the suboccipital ridge, the approximate location of the greater and lesser occipital nerve, as well as the potential incision site, and placement of the two posterior occipital leads. After this was done, the patient was allowed to return to the recumbent position."
based on this note would the correct CPT be the 64575 or the 64555?
Thank you!
