Answer: You should report J3490 (Unclassified drugs), unless your payer instructs otherwise, because no permanent HCPCS code has been assigned to diltiazem HCl.
Depending on which insurer is processing your claim, you may also need to submit documentation with your claim to show which drug you administered, how much you administered, and for what condition you used it.
