Quick answer
J1756
What Medicare pays for Venofer (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%) |
|---|---|---|---|
| J1756 | Iron sucrose injection | 1 mg | $0.227 |
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 Venofer
A concrete, paste-checkable example using J1756’s own billing-unit basis and vial sizes — not a hypothetical.
| Scenario | 100 mg adult fixed dose (HDD-CKD, one vial per dialysis session) |
| Dose administered | 100 mg |
| Billing unit basis | 1 unit = 1 mg |
| Billing units (dose ÷ unit basis, rounded up) | 100 units of J1756 |
| Vial combination drawn (min-waste plan) | 1 × 100 mg vial |
| Discarded (waste) | None |
| Wastage modifier (JW / JZ) | Bill all 100 units on a single line with JZ (attests zero drug discarded). What JZ/JW mean → |
| Medicare allowable (ASP + 6%, 2026 Q3) | 100 units × $0.227/unit = $22.70 |
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.
Dose source: drugs/venofer.html — HDD-CKD dosing: "100 mg slow IV injection ... 1-3 times per week during dialysis"; FAQ: "used as a whole-vial dose ... with zero waste in adult fixed-dose regimens" (adult regimen, not the pediatric 0.5 mg/kg path).

Venofer 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 J1756) 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).
