Coverage Criteria for Single‑Dose Vial (SDV) Pharmaceutical Waste

Coverage criteria for SDV pharmaceutical waste

Reimbursement is allowed for pharmaceutical waste from single-dose vials when ALL of the following are met:

ALL of the following

Drug/biologic prepared from a single-dose vial (SDV) is medically appropriate for the member and calculated to optimize utilization and minimize pharmaceutical waste.
Medical record documents the amount administered, date and time, amount discarded, and the reason for the wasted amount.
Administered units are reported on one claim line; discarded/wasted units are reported on a separate claim line with modifier JW when the discarded amount is eligible for reimbursement.
Exception for zero waste
- Append modifier JZ to the HCPCS code when the actual dose administered from an SDV equals the billing unit and zero waste occurred; do not separately bill waste in this case.
- If the billing unit covers the administered dose such that the remaining small amount of wastage is included within the reported units (example: code unit is 10 units, 95 units administered from a 100-unit vial), report the code with JZ and do not separately bill the residual as JW.
Wasted doses due to contamination, expiration, spillage, damage, or breakage are not eligible for reimbursement.
Providers are expected to use the most cost-effective vial or combination of vials to avoid waste (for example, use two 20-unit vials instead of one 100-unit vial to supply a 40-unit dose).
This policy does not apply to multi-dose vials (MDVs).

Operational billing detail: the number of units reported is based on the dosage indicated in the HCPCS code descriptor, not necessarily the milligrams actually given; report actual units administered on one line and eligible discarded units on a separate line with JW as described above.

Reporting Modifiers and Units for SDV Waste

Modifiers for SDV waste reportingHCPCSCovered

JW	Drug amount discarded/not administered to any patient
JZ	Zero amount discarded/not administered to any patient

Modifiers for SDV waste reporting - commentsmixed

JW	Unused portion of the drug/biologic not administered may be eligible for reimbursement
JZ	Unused portion of drug/biologic used is less than the billing unit or zero drug/biologic is discarded

Reporting units — administered vs wasted

Report administered unitsReport the actual units administered on one claim line using the HCPCS code with units reflecting the dosage given.

Report wasted unitsReport discarded/wasted units on a separate claim line with modifier JW appended when the discarded amount is eligible for reimbursement.

When to use JZAppend modifier JZ to the HCPCS code when the actual dose administered equals the billing unit (zero waste); do not separately bill waste in this case.

When JW is not permittedModifier JW is not permitted when the actual dose administered from an SDV is less than the billing unit defined by the HCPCS code; bill with JZ instead and discard the remainder.

Unit reporting basisThe number of units reported is based on the dosage indicated in the HCPCS code descriptor, not necessarily the milligrams administered.

Billing and Documentation Actions Required of Providers

Billing Rule

Billing and Documentation Actions for SDV Waste

The health plan allows reimbursement for single-dose vial (SDV) pharmaceutical waste when billed and documented correctly. Report the HCPCS code for the drug/biologic on one claim line with the actual units administered, and report the unused/wasted amount on a separate claim line with modifier JW when applicable. If there is zero waste, append modifier JZ to the HCPCS code. Modifier JW is not permitted when the actual dose administered from an SDV is less than the billing unit defined by the HCPCS code; in that situation the provider may bill with JZ for the administered amount and discard the remainder. Providers must document in the member's medical record the amount administered, date and time of administration, amount discarded/wasted, and the reason for the waste (for example: contamination, expiration, spillage, damage, or breakage).

Report administered units on one line and wasted units on a separate line with modifier JW when applicable.
Append modifier JZ when there is zero waste.
Modifier JW is not permitted when administered dose is less than the billing unit; bill with JZ for the administered amount and discard the remainder.
Document amount administered, date/time, amount discarded, and reason for waste in the medical record.
Do not reimburse doses prepared from SDVs that are not administered because they are contaminated, expired, spilled, damaged, or broken.

Key Definitions

DefinitionPharmaceutical Waste — The discarded amount not administered to any patient.

Single‑Dose Vial — definition
