Quick answer
J9034
What Medicare pays for Bendeka (2026 Q3)
Once a claim carries a covered diagnosis, Medicare Part B reimburses the drug at the ASP + 6% payment limit. Current allowed amounts per billing unit:
| HCPCS | Description | Per unit | Allowed (ASP + 6%) |
|---|---|---|---|
| J9034 | Inj., bendeka 1 mg | 1 mg | $12.532 |
Source: CMS ASP Drug Pricing File, 2026 Q3. Payment = ASP + 6% per unit; multiply by units billed (watch JZ/JW wastage). Your patient's share is typically 20% after the deductible. Estimate the full cost & patient out-of-pocket →
Worked billing example for Bendeka
A concrete, paste-checkable example using J9034’s own billing-unit basis and vial sizes — not a hypothetical.
| Scenario | CLL dose — 100 mg/m² for a 1.7 m² reference patient (170 mg) |
| Dose administered | 170 mg |
| Billing unit basis | 1 unit = 1 mg |
| Billing units (dose ÷ unit basis, rounded up) | 170 units of J9034 |
| Vial combination drawn (min-waste plan) | 2 × 100 mg vials |
| Discarded (waste) | 30 mg |
| Wastage modifier (JW / JZ) | Bill the 170 administered units on one claim line (no wastage modifier), and the 30 discarded units on a separate line with JW. Do not add JZ — JW and JZ are never billed together for the same drug on the same date of service. What JZ/JW mean → |
| Medicare allowable (ASP + 6%, 2026 Q3) | 200 units × $12.532/unit = $2506.40 |
This is Medicare’s allowable payment limit (ASP + 6%, 2026 Q3) — not a promise of what you will be paid. Actual paid amount depends on sequestration and whether the claim carries a covered diagnosis.

Bendeka is a physician-administered biologic billed under Medicare Part B (not the Part D pharmacy benefit). Under Part B, Medicare pays the practice for the drug (HCPCS J9034) plus its administration — but only when the claim's diagnosis (ICD-10) code supports medical necessity. Each MAC publishes the specific covered diagnoses in a Billing & Coding Article; a claim with a diagnosis outside that list is typically denied as not medically necessary (CO-50).
