I can’t find the dx code for temporal artery mass. There is nothing noted on the billing sheets that mass was due to an aneurysm or pseudoaneurysm. So I don’t think these codes would be appropriate. The surgeon office used H53.8 – Other visual disturbances but that doesn’t seem right either. The mass is the case of the visual disturbance. The procedure code is 37609 – Ligation or biopsy, temporal artery.

I was thinking perhaps R22.0 Localized swelling, mass and lump, head but that doesn’t seem right since this is vascular.
