Ask Dr. Z

I could not find a CPT code for this px. Is code 76000 sufficient? "Transnasal sphenopalatine block. Clinical history: 35-year-old female with chronic headaches, referred for a Sphenocath procedure. The patient's nostrils were first anesthetized with 2% lidocaine via an atomizer. A Sphenocath catheter was then inserted in the left nostril with the patient in supine position with the head tilted back and in Trendelenburg. 1.5 mL of a mixture of Visipaque and 4% lidocaine was injected in the right nostril with the spheno-catheter in appropriate position. Fluoroscopy confirmed that the mixture of contrast and lidocaine accumulated in the sphenoethmoid recess. The catheter was removed and placed in the right nostril. The procedure was repeated as above. Conclusion: Successful injection of transnasal lidocaine and contrast into the sphenoethmoid recess. Fluoroscopy time 1.1 minutes Air Kerma 1 Dose area product of 0.21 cm square."
