Question: Sphenopalatine Artery Catheterization

How would I code the following? Specifically, the catheterizations of the sphenopalatine arteries. Would you only code based on the angiograms that were performed?

Catheterization of the following vessels : 1. Left common carotid artery. 2. Left external carotid artery. 3. Left internal maxillary artery. 4. Left sphenopalatine artery. 5. Right common carotid artery. 6. Right external carotid artery. 7. Right sphenopalatine artery.

Diagnostic angiographic interpretation of the following images: 1. Bilateral cervical carotid artery angiograms. 2. Bilateral external carotid artery angiograms.


Answer:

If imaging is done via the common carotids and the external carotids, with imaging of the neck and face, the CPT codes are 36222-50 and 36227-50. CPT code 36227 includes the basic external carotid selection and imaging, along with all branches selected and imaged off the external carotid, including the sphenopalatine artery.
