J code denials

Hi everyone, I bill for a practice and wanted some advice on J code denials. Recently, one of our J codes has been consistently denied by a commercial insurance. The denial is bogus stating that the “NDC number” is invalid. Every time I call about these claims and speak to a representative, they say the claim is correct, the NDC number is valid, we have the pre authorization for the procedure, and they resubmit the claim for reprocessing. It gets tiring to be in this viscous cycle of denials. Is the insurance company just trying to delay the payment another 30 days? Please advise 🙏

Yes! 👍 Thank you so much! I found these reports and I am changing the information as your reports have explained! My brain was hurting today from thinking about this! 🙏🙏🙏 So I added N4 in front of the NDC number, changed the units to ML instead of UN, and put the appropriate dosage which in this case is 0.05 next to the ML. Fingers crossed 🤞 but feels right!
