Unclassified or Not Otherwise Classified (NOC) Drug Codes: Rejected if Not Submitted Correctly
When billing for services using the unclassified drug codes or not otherwise classified (NOC) drug codes, it is important to submit only the required documentation. Submitting additional information beyond what is required, or submitting conflicting information, could cause the service to be rejected.
Required Documentation
- The drug name
- The total dosage (this is amount actually administered)
- The National Drug Code (NDC) number
As a reminder, please do not file unlisted codes for procedures (e.g., surgical) without indicating a description of the service being provided for payment. The documentation is to be entered in the appropriate comment/narrative field.
Correctly Reporting the Amount of a Drug Being Billed
When providers report the quantity of a drug that was administered, it should be expressed in the unit of measure that is appropriate for that drug or biological. NOC drugs should be reported with the dose administered. Drug waste should be billed with the HCPCS modifier JW. Drugs amounts expressed in "mg/mL" or "mg mL" will be rejected for insufficient information. The only exception to this will be compounded drugs which can be reported as "mg/mL."

Quantity Billed/Number of Services
Providers should enter “1” in the quantity billed/number of services field and enter the total amount of the drug or biological actually administered (in mg or mcg) in block 19 or the electronic equivalent field.
If any of the required documentation is missing, incomplete or invalid, the service(s) will be rejected.
Drugs Requiring Invoices/Supporting Documentation
Please refer to the “Services and Circumstances That Require Additional Documentation” article found on Palmetto GBA’s website.
Drugs Requiring Only Comment in Narrative/Block 19
Besides the required documentation (name, dosage and NDC), some drugs may require additional comments in the narrative. These situations would be addressed in an article for the specific drug on CMS Medicare Coverage Database (MCD). For other references of required information, refer the FDA Website.
