How It Works
From a HCPCS Code to a Billable Answer
-
Start with what you know
Type a J-code, Q-code, C-code, or just the drug name. The search finds the match and fills in the rest.
-
Read the whole record
The descriptor, every NDC that aligns to it, the billing units, and ASP, WAC, and AWP pricing all sit on one screen.
-
Send a clean claim
Bill the right number of units at the current Medicare Payment Limit, and get it right the first time.
Free Tool
Billing Units Calculator
Every HCPCS drug code defines one billing unit — J9035 is “Injection, bevacizumab, 10 mg,” so a 400 mg dose is 40 units. Pick a code, enter the dose administered, and get the unit count the claim needs.
Fractional doses round up to the next whole unit, which leaves discarded drug to account for — see billing drug wastage with the JW and JZ modifiers.

FAQs
HCPCS Drug Code Lookup FAQs
How drug codes, NDCs, billing units, and pricing fit together on a clean claim.
Still have a question? Contact usWhat is a HCPCS code?
HCPCS stands for the Healthcare Common Procedure Coding System, the standard code set used to bill physician-administered drugs to Medicare and commercial payers. A HCPCS code such as a J-code identifies both the drug and its unit of measure. BuyandBill.com provides the official descriptor and publicly available coding detail for every drug code we cover: A Code, C Code, J Code, P Code, Q Code and S Code. A subscription unlocks full NDC alignments and pricing.
How is a HCPCS code different from an NDC?
The two codes answer different questions. The HCPCS code tells the payer which drug was administered and in what unit of measure. The NDC identifies the exact package the drug came from, including the manufacturer, strength, and package size. BuyandBill.com links HCPCS codes to their aligned NDCs and provides the billing-unit conversion between the two; full NDC alignments and pricing require a subscription.
How do I calculate billing units for a HCPCS code?
Each HCPCS drug code defines a standard unit dose, and the number of units billed is the administered dose divided by that amount. J9035, for example, is defined as "Injection, bevacizumab, 10 mg," so a 400 mg dose is billed as 40 units. Incorrect unit counts are among the most common causes of denied drug claims. BuyandBill.com displays the unit definition and the package-to-unit conversion for publicly available NDCs, and a subscription unlocks the full set of aligned NDCs.
Do I bill a CPT code along with the drug's HCPCS code?
In most cases, yes. A complete claim includes the HCPCS code for the drug itself and a CPT administration code for the service of giving it, such as 96372 for a therapeutic injection or 96413 for the first hour of a chemotherapy infusion. See our guide to CPT drug administration codes for how the two work together.
What if a drug doesn't have its own HCPCS code yet?
New drugs often reach the market before CMS assigns them a permanent code. Until one is issued, the drug is billed under a not-otherwise-classified (NOC) code, such as J3490 for unclassified drugs, J3590 for unclassified biologics, or J9999 for chemotherapy drugs. The claim must also report the 11-digit NDC and the dose administered. CMS reviews new code applications quarterly, so a permanent code usually follows.
How often are HCPCS codes and pricing updated?
CMS updates the HCPCS code set quarterly, with new drug codes taking effect in January, April, July, and October. BuyandBill.com follows the same quarterly schedule for ASP and the Medicare Payment Limit and applies CMS corrections as soon as they are published. WAC and AWP pricing and NDC-to-HCPCS alignments are refreshed weekly.
Where does the HCPCS data come from?
Code descriptors and the Medicare Payment Limit come directly from CMS. ASP is calculated by BuyandBill.com, and NDC-to-HCPCS alignments and WAC and AWP pricing are collected directly from drug manufacturers.
Can I run a quick HCPCS search without an account?
Yes. Searching is free, and every drug code page shows the descriptor, basic coding detail, and the current Medicare Payment Limit without a login. The full set of aligned NDCs and manufacturer pricing (ASP, WAC, and AWP) come with a subscription, and a 7-day free trial opens all of it.
