Billing unlisted drug procedure codes J3490 and J9999

Procedure codes J3490 and J9999 are unlisted codes for injection services. 

• J3490 - Unclassified drugs
• J9999 - Not otherwise classified, antineoplastic drugs

When billing for these codes, the provider must indicate the name, strength, and dosage of the drug in block 19 on the CMS-1500 claim form (or in 2400.SV101-7 in the ANSI 837 claim file). 

You may find pricing information for most unlisted drugs on the CMS website.
