💊 About Iron Sucrose Injection DRUG GUIDE
Iron sucrose injection is used to treat iron deficiency anemia (IDA) — low red blood cell counts caused by not enough iron — in people with chronic kidney disease (CKD).
It is given to adults on hemodialysis, adults not on dialysis, and adults on peritoneal dialysis.It is also used for iron maintenance treatment in children 2 years and older with CKD who are on erythropoietin therapy, whether they are on hemodialysis, peritoneal dialysis, or not on dialysis.

🧮 Dosing & billing-units calculator HCPCS UNITS
One billing unit of J1756 = 1 mg. Enter a regimen to convert dose → billing units and project a full course.
Billing units = dose ÷ HCPCS unit size. Most payers require whole units — round per the payer's policy. “Est. Medicare pay” uses the current payment limit. For single-dose vials, drug discarded after administration may be separately billable with modifier JW (JZ when none is discarded) where allowed. Always verify payer-specific rounding before billing.
🔁 NDCs that bill under J1756 LEAST EXPENSIVE FIRST
26 NDCs map to J1756. Bill units = how many HCPCS units one package represents. Est. pay / pkg = payment limit ($0.227/unit) × that package's bill units.

Source: CMS Physician/Supplier Procedure Summary (PSPS), CY2024 — Medicare Part B carrier + DME fee-for-service claims (excludes Medicare Advantage). Figures are for the whole HCPCS code, which may cover uses beyond this drug. ⚠ CMS hides any figure covering fewer than 11 patients (a privacy rule), so totals — especially denials and low-volume codes — run a little low.
🗺️ Where J1756 is utilized CMS · BY PROVIDER · 2024
Medicare Part B services for this code by the rendering provider's state — 9,655,603 services across 32 states & territories in 2024 (CMS reports include DC and U.S. territories). Switch to per 100k to compare states fairly regardless of population. Hover or tap a state for its top ZIP codes.
Hover or tap a state to see its numbers + top ZIP codes.
Per-capita = services ÷ 2023 state population × 100,000 (so high-population states aren't automatically "hotter"). Counts reflect the provider's location, not the patient's. Providers with fewer than 11 patients are hidden by CMS for privacy, so totals run low and per-100k can be noisy in small states — read this as relative geography, not exact counts.

Figures are estimates for reference and may lag the source files. Always verify against the current CMS files and your payer's policy before submitting claims.
⚠️ Practical billing caveats
- A crosswalk is not coverage. An NDC mapping or a published payment limit does not guarantee a payer will cover or pay this code. Check the specific plan's policy.
- Units ≠ milligrams. Bill the number of HCPCS units (dose ÷ the code's unit size), not the milligram dose. Use the calculator above.
- Discarded drug. For single-dose vials, drug discarded after administration may be separately billable with modifier JW (and JZ when nothing is discarded) where the payer allows.
- Rounding & partial units. Many payers require whole units; round per the payer's policy, not automatically up.
- The code can cover more than this drug. Some HCPCS codes span multiple products or strengths — confirm the exact code for the product administered.
- Figures lag. ASP limits change quarterly and utilization data are released with a delay. Verify against the current CMS files before billing.
❓ J1756 billing FAQ
What is HCPCS code J1756?
J1756 is a HCPCS Level II J-code used to bill Injection, iron sucrose, 1 mg under Medicare Part B and most medical (not pharmacy) benefits.
What is the billing unit for J1756?
One unit of J1756 represents 1 MG. Report the number of units equal to the dose administered divided by 1 MG.
How many units of J1756 should I bill?
Divide the dose administered by the code's unit size (1 MG) to get the number of billing units, then round per your payer's policy. The calculator on this page converts a dose into billing units and projects a full course.
How much does Medicare pay for J1756?
The Medicare Part B payment limit is $0.227 per unit (Q3 2026), based on ASP + 6%. After the 2% sequester the effective payment is about $0.222 per unit. Payment limits are revised quarterly.
Which NDCs bill under J1756?
26 NDCs currently map to J1756 in the CMS ASP NDC-HCPCS crosswalk. See the NDC crosswalk table above for each product, package, billing units and estimated reimbursement.
Does a crosswalk mean J1756 is covered?
No. An NDC-to-HCPCS crosswalk and a published payment limit do not guarantee coverage or payment. Coverage depends on the payer, the diagnosis and the site of care — always verify the current policy before billing.
For professional billing reference only — verify against the current CMS files before submitting claims.
