HCPCS Drug Billing Units (Dose -> Units)

Convert an administered dose to HCPCS/J-code billing units by the code descriptor unit size, with the rounding rule and a clean-multiple check.

Open the tool → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.

Example

Administered dose: 35
Dose unit: mg
Billing unit size per the HCPCS descriptor: 10
Billing unit measure: mg
Rounding: Round up (single-dose default)

Result: 35 mg / 10 mg per unit = 3.5 -> 4 billing units (rounded up); not a clean multiple.

The tool opens with these values already filled in. Replace them with your own.

What you enter

Administered dose
Dose unit
Billing unit size per the HCPCS descriptor
Billing unit measure
Rounding: up, down, or nearest (default up)

How this is calculated

CMS HCPCS Level II drug code descriptors (each J-code's billing unit of measure) and CMS Pub. 100-04 Ch. 17: the dose is divided by the code's billing-unit size and rounded per the unit's rule. The unit size is entered from the descriptor -- no drug-pricing file ships. Read the source ↗
