I am getting co16 denials but for J3301 and J9040. BCBS rep states invalid NDC for mine. Correct NDC is on the claim. It started in August for me, all were paid prior for the entire 15 years I've been billing these codes to BCBS.I could not find an Anthem policy and the billing did not change from prior months billing. On a FB group I found where others were having the same issue with J1010 and are billing correctly. I thought I would post here to see if others are having the same issue.
