Monitor payer policy activity
This policy governs billing and documentation requirements for reporting drug or biological wastage using JW and JZ modifiers for Baylor Scott & White Health Plan; it affects providers submitting claims for single-use vial/package drugs across the plan's lines of business.
No material clinical or coverage changes in this revision.
When Wastage May Be Reported
Coverage criteria for reporting wastage
Covered when ALL of the following conditions consistent with CMS guidance are met:
ALL of the following
ALL of the following
- Vial/package must be single‑use and leftover must be actually discarded (not reused).
ALL of the following
- Units billed for the discarded amount must correspond to the smallest dose (vial) available for purchase from the manufacturer/supplier that could provide the appropriate dose for the patient (reimbursement limited to dosing for smaller vials when larger are used inappropriately).
ALL of the following
- Report the amount administered on one claim line and the discarded amount on a separate claim line with the JW modifier appended to the associated CPT/HCPCS code.
- If there is no discarded amount, report the administered amount with the JZ modifier on the claim line.
ALL of the following
- Do not append JW when the billing unit equals or exceeds the total actual dose plus discarded amount (i.e., when a single billed unit already represents the administered plus discarded drug), as this would result in overpayment.
ALL of the following
- If only larger dose vials are available or larger vials were used when smaller would suffice, providers may request coverage through the appeals process and must provide an explanation and, if required, a corrected claim showing breakout of charges, allowed waste for the smaller dosing, billed amounts and NDC(s). Payment is limited to dosing for the smaller vials and associated allowable waste.
ALL of the following
- JW/JZ modifiers do not apply to drugs that are not separately payable (for example, packaged OPPS/ASC drugs), drugs administered in FQHC or RHC settings, or drugs assigned OPPS status indicator 'N' or payment indicator 'N1' (ASC).
ALL of the following
- When the administered dose is not a multiple of the HCPCS billing unit, round to the next higher whole HCPCS unit for billing (e.g., 2.5 mg billed as 3 units if the HCPCS unit = 1 mg).

Billing and Documentation Steps for JW/JZ
Billing & documentation for JW/JZ — document discarded amounts and separate JW claim line
Document discarded amounts in the patient’s medical record and bill the discarded amount on a separate claim line using the JW modifier. Report the administered amount on one claim line and the discarded amount on a separate line with JW per CMS guidance. Do not append JW when the billing unit equals or exceeds the total actual dose plus discarded amount, as this would result in overpayment. Retain medical record documentation showing the discarded amounts.
- Document discarded amounts of drugs or biologicals in the patient’s medical record (required).
- Bill discarded amount on a separate claim line using the JW modifier; report administered amount on its own claim line.
- Do not append JW when the billing unit is equal to or greater than the total actual dose plus discarded amount (example: a 7 mg dose billed as one 10 mg unit; do not submit a separate JW line for the 3 mg discarded).
- When more than one vial with different NDCs is used, report each NDC on a separate claim line with units given and add an additional line indicating discarded units with JW.
Appeal process when larger vials are used or only larger vials available
If only larger dose vials were available or a larger vial was used when a smaller vial would have sufficed, request coverage through the appeals process and provide an explanation and corrected claim breakout showing allowed waste for the smaller dosing and the excessive waste separated by billed amount and NDC.
- Explain why higher dose vials were utilized as part of the appeal.
- Include a corrected claim with a breakout of charges: one line showing allowed waste for the smaller dosing (billed amount and NDC) and another line showing the excessive waste (billed amount and NDC).
- Payment is limited to dosing for the smaller vials and any associated waste; reimbursement for excessive waste is limited accordingly.
