⚠️
ESRD PPS bundled payment. Venofer administered to in-center hemodialysis-dependent CKD (HDD-CKD) patients during dialysis is bundled into the Medicare ESRD Prospective Payment System (PPS) per-treatment payment. The dialysis facility is paid the bundled per-treatment rate and Venofer is NOT separately billable to Medicare Part B in that setting. Only NDD-CKD use (physician office, separately staffed infusion suite) and certain PDD-CKD scenarios outside the bundle are separately billable. Always confirm setting and the dialysis facility's billing protocol before submitting a J1756 claim. See ESRD PPS bundling section.
ℹ️
Venofer = lowest per-mg IV iron in class. $0.223/mg vs Injectafer $1.103/mg, Monoferric ~$1.05/mg, Feraheme (Q0138/Q0139). Trade-off: Venofer requires multiple visits (5–10 doses) to reach therapeutic 1,000 mg cumulative. For non-dialysis patients, weigh per-mg cost vs total chair time and visit burden — single-dose competitors (Injectafer 750 mg ×2, Monoferric 1,000 mg ×1) cost more per mg but fewer visits. See IV iron class comparison.

Why Venofer wins for HDD-CKD: dialysis patients are at the chair 3×/week anyway. Venofer's 100 mg slow IV push during dialysis adds zero visit burden. The lower per-mg ASP makes it the economic default for dialysis chains. NDD-CKD and non-CKD IDA patients have a much harder choice — Injectafer or Monoferric save 3–9 office visits at higher per-mg cost.

Most payers will require ferritin <100 ng/mL or TSAT <20% plus a documented oral iron failure or intolerance. Some prefer Injectafer / Monoferric for non-CKD because of single-dose convenience — verify formulary preference before starting Venofer for non-CKD IDA.

Dosing & unit math FDA label verified

From FDA prescribing information (Venofer, American Regent).

Hemodialysis-dependent CKD (HDD-CKD) — the workhorse use

  • 100 mg slow IV push over 2–5 minutes during a hemodialysis session
  • 1–3 sessions per week; typical induction = 10 consecutive HD sessions to reach 1,000 mg cumulative
  • Maintenance per Hgb / ferritin / TSAT — many patients receive ongoing 100 mg every 1–2 weeks
  • Each dose = 1 vial (100 mg / 5 mL). 1 mg = 1 unit → bill 100 units per dose
  • Critical: ESRD PPS bundled when given during in-center HD — not separately Part B

Non-dialysis-dependent CKD (NDD-CKD)

  • 200 mg IV on 5 different days over a ~14-day period (cumulative 1,000 mg)
  • Each dose may be slow IV injection (over 2–5 min undiluted) or IV infusion in 100 mL NaCl over 15 min
  • Each dose = 2 vials (200 mg). Bill 200 units per dose
  • Five-dose regimen total: 1,000 units across 5 visits
  • Separately billable Part B (J1756) — not bundled

Peritoneal dialysis-dependent CKD (PDD-CKD)

  • Dose 1 (Day 0): 300 mg IV infusion over 90 min (3 vials → 300 units)
  • Dose 2 (Day 14): 300 mg IV infusion over 90 min (3 vials → 300 units)
  • Dose 3 (Day 28): 400 mg IV infusion over 2.5 hours (4 vials → 400 units)
  • Cumulative 1,000 mg across 3 visits

Pediatric (≥2 yr) HDD-CKD

  • 0.5 mg/kg per HD session, weekly, for up to 12 weeks (max 100 mg per dose)
  • Bill the actual mg administered (not rounded)
  • Pediatric dosing always produces partial-vial waste → JW modifier applies on the wasted portion

Hgb / iron monitoring

Per KDIGO + KDOQI CKD anemia guidelines: hold IV iron when ferritin >500 ng/mL or TSAT >30%; resume when both fall below thresholds and Hgb <target. Document baseline and re-check ferritin/TSAT before each induction course. Payer PA criteria typically mirror these thresholds.

NDC reference FDA NDC Directory verified May 2026

NDC (10/11-digit)PackageUse
0517-2340-01 / 00517-2340-01 100 mg / 5 mL single-dose vial — 1 vial per carton Standard institutional and HD use
0517-2340-10 / 00517-2340-10 100 mg / 5 mL single-dose vial — 10-vial tray Dialysis facility / infusion suite bulk
Use vial-level NDC for IV iron claims. Unlike multi-component oncology cartons, IV irons are typically billed at the vial NDC. Confirm payer-specific NDC requirement — some payers want the outer carton NDC, others the vial. American Regent's billing guide lists 00517-2340-01 for most claim contexts.
Storage & handling: Store at 25°C (77°F); excursions permitted 15–30°C. Do not freeze. Single-dose vials — discard unused portion. 100 mg/5 mL = 20 mg/mL elemental iron.
Phase 2 Code the claim 96374 (IV push) is correct for slow-injection administration. ESRD PPS rules override Part B in HD setting.

Administration codes CPT verified May 2026

Venofer is given as IV push or short infusion — the right CPT depends on actual administration technique.

CodeDescriptionWhen to use
96374 Therapeutic, prophylactic, or diagnostic injection (specify substance/drug); intravenous push, single or initial substance/drug Primary code for Venofer slow IV push. Standard 100–200 mg dose given over 2–5 minutes (or up to 15 min undiluted) is push, not infusion.
96365 Intravenous infusion, for therapy/prophylaxis/diagnosis; initial, up to 1 hour Use when Venofer is diluted in 100 mL NaCl and infused over 15 min (NDD-CKD option) or for 300 mg PDD dose over 90 min.
96366 IV infusion; each additional hour For 400 mg PDD-CKD dose infused over 2.5 hours — pair with 96365 for the second hour.
96375 Each additional sequential IV push of a new substance/drug Rarely needed for Venofer monotherapy. Use if a separate IV push drug is given the same encounter.
96413 Chemotherapy IV infusion NOT appropriate. Iron sucrose is not chemotherapy. Use 96374 or 96365.
Why 96374, not 96365: The FDA label specifies slow IV injection for the most common Venofer use (100 mg HDD and 200 mg NDD doses). When given undiluted over 2–5 minutes, the administration is by definition an IV push (96374), not an infusion. 96365 only applies when the drug is diluted and run over 15+ minutes via a programmed infusion.
HDD-CKD setting reminder: When Venofer is given during in-center hemodialysis, the admin code is part of the ESRD PPS bundle — you typically do not bill 96374 separately. Admin codes apply only when Venofer is billed under Part B (NDD-CKD office visits, PDD-CKD scheduled infusions, off-label IDA in non-dialysis settings).

Modifiers CMS verified May 2026

JZ — required on virtually every adult Venofer claim

Effective July 1, 2023, CMS requires the JZ modifier on all single-dose container claims when no drug is discarded. Venofer's 100 mg/5 mL single-dose vial is used as a whole-vial dose — 100 mg = 1 vial, 200 mg = 2 vials, 300 mg = 3 vials, 400 mg = 4 vials. Adult fixed-dose regimens produce zero waste. JZ applies to virtually every adult J1756 Part-B claim.

JW — pediatric weight-based dosing only

JW reports the discarded portion of a single-dose vial. For Venofer, JW only applies to pediatric weight-based dosing where partial-vial waste occurs. Example: a 20 kg child receiving 10 mg (0.5 mg/kg) uses one 100 mg vial and discards 90 mg — bill JW with 90 units of waste on a separate claim line. One of JZ or JW must be on every J1756 claim.

Modifier 25 — same-day E/M

Use modifier 25 on the E/M code when a significant, separately identifiable evaluation and management service is performed on the same day as the IV iron infusion (e.g., baseline anemia work-up at first visit). Routine pre-infusion vitals are bundled.

340B modifiers (JG, TB)

For 340B-acquired Venofer, follow your MAC's current 340B modifier policy. American Regent's billing materials do not provide 340B-specific instructions; defer to MAC and 340B program manual.

ICD-10-CM by CKD setting FY2026 verified May 2026

ICD-10 selection drives PA approval. Pair the CKD stage code with the iron-deficiency anemia code.

PDD-CKD N18.6 (CKD stage 5) D63.1 + Z99.2 Same trio as HDD; PD scheduling differs but coding is similar
Off-label IDA (non-CKD) D50.0 (chronic blood-loss IDA), D50.8, D50.9 Underlying cause: N92.x HMB, K50/K51 IBD, etc. Higher PA scrutiny; document oral-iron failure
Pediatric (≥2 yr) CKD N18.x (per stage) D63.1 Use age-appropriate documentation; pediatric anemia thresholds differ
D63.1 is the load-bearing code for IV iron in CKD. Most payer LCDs and medical policies require D63.1 (anemia in chronic kidney disease) as a primary or secondary diagnosis. Submitting only the CKD stage code without D63.1 will trigger denial — even if the patient clearly has anemia.
Lab thresholds in PA criteria: Most payers require ferritin <500 ng/mL AND TSAT <30% documented in the prior 90 days. Some plans require ferritin <100 ng/mL or TSAT <20% for non-CKD IDA. Schedule labs at baseline and 4–8 weeks after induction.

Site of care & place of service Verified May 2026

Site of care is uniquely complicated for Venofer because of the ESRD PPS bundle. Most other Part B drugs have payer site-of-care UM steering away from HOPD; Venofer has Medicare regulatory steering INTO the dialysis facility's bundled payment when given during HD.

ESRD PPS bundled payment — the load-bearing rule for J1756 CMS PPS verified May 2026

More denials are written for J1756 over PPS bundling than for any other reason. Get this right.

The Medicare End-Stage Renal Disease Prospective Payment System (ESRD PPS) was implemented January 1, 2011. Under PPS, Medicare pays the dialysis facility a single bundled per-treatment rate that covers all renal-related items and services, including ESAs (epoetin, darbepoetin), IV iron (including Venofer), vitamin D analogs, and laboratory tests.

The classic denial: Office tries to bill J1756 to Part B for a patient who received Venofer during in-center hemodialysis on the same date the dialysis facility billed the per-treatment bundle. Medicare denies as already-paid via the bundle. Fix: confirm setting before submitting; coordinate with the dialysis facility billing team; only submit Part B claims for genuinely non-bundled administrations.

Acute Kidney Injury (AKI) exception

Effective January 1, 2017, dialysis facilities can bill Medicare for furnishing renal dialysis services to AKI patients. AKI dialysis (limited duration, expected renal recovery) is paid under the ESRD PPS base rate but with different drug-bundling rules — some drugs that are bundled for ESRD are separately billable for AKI. Verify current AKI bundling list before billing.

Documentation expectation regardless of bundling

Even when Venofer is bundled (not separately billed), the dialysis facility must document NDC, dose, lot number, administration time, and ferritin/TSAT values for: ESRD QIP quality reporting, MIPS for nephrology practices, internal pharmacy P&T tracking, and audit defense. Don't skip documentation just because the claim isn't itemized.

Step therapy

Oral iron failure is the most common step requirement for non-CKD IDA. CKD anemia typically does not require oral iron failure given CKD-specific guidelines. Some payers may require trial of a less expensive IV iron before approving Injectafer or Monoferric — Venofer is often the first-line preferred IV iron precisely because it is the cheapest per mg.

Frequently asked questions

What is the HCPCS code for Venofer?

Venofer (iron sucrose) is billed under HCPCS J1756 — "Injection, iron sucrose, 1 mg." Each milligram of elemental iron equals one billable unit. So 100 mg = 100 units, 200 mg = 200 units, 300 mg = 300 units. The vial is labeled 100 mg/5 mL (20 mg/mL elemental iron). J1756 has been a permanent HCPCS code for years and is the workhorse IV iron J-code for hemodialysis-dependent CKD anemia.

Is Venofer billed under Medicare Part B in hemodialysis patients?

No — for in-center hemodialysis-dependent CKD (HDD-CKD) patients, Venofer given during dialysis is bundled into the ESRD Prospective Payment System (PPS) per-treatment payment. The dialysis facility receives the bundled per-treatment amount and Venofer is NOT separately billable to Part B in that setting. Only NDD-CKD use (physician office), PDD-CKD scheduled infusions outside the bundle, and off-label IDA in non-dialysis settings are separately billable Part B. Always confirm setting and the dialysis facility's billing protocol before submitting a J1756 claim.

What is the dosing for Venofer?

Dosing depends on CKD stage. HDD-CKD: 100 mg slow IV push 1–3 times per week during dialysis until cumulative 1,000 mg, then maintenance per labs. NDD-CKD: 200 mg IV × 5 doses on different days over ~14 days (cumulative 1,000 mg). PDD-CKD: 300 mg IV × 2 doses + 400 mg × 1 (cumulative 1,000 mg). Pediatric (≥2 yr) HDD-CKD: 0.5 mg/kg IV per session, max 100 mg.

What administration CPT do I use for Venofer?

CPT 96374 — "Therapeutic IV push, single or initial substance/drug." This applies when Venofer is given as the standard slow IV push (2–5 minutes). Some facilities elect to dilute and infuse Venofer over 15 minutes, in which case 96365 (therapeutic IV infusion, up to 1 hour) applies. Choose the code that matches actual administration technique. Do NOT bill 96413 — iron sucrose is not chemotherapy.

Do I bill JZ or JW for Venofer?

Bill JZ on virtually every adult Venofer claim. The 100 mg/5 mL single-dose vial is used as a whole-vial dose (100 mg = 1 vial, 200 mg = 2 vials, 300 mg = 3 vials, 400 mg = 4 vials) with zero waste in adult fixed-dose regimens. JW only applies to pediatric weight-based dosing where partial-vial waste occurs. One of JZ or JW must be on every J1756 claim per CMS's July 2023 single-dose container policy.

What is the Medicare reimbursement for J1756?

For Q2 2026, the Medicare Part B payment limit for J1756 is $0.223 per mg (ASP + 6%). The standard 100 mg HDD-CKD dose reimburses at approximately $22.30 per session (when separately billable in NDD setting); 200 mg NDD-CKD dose at approximately $44.60; 300 mg PDD-CKD dose at approximately $66.90. Cumulative 1,000 mg course: ~$223 in drug cost. Sequestration (~2%) reduces actual paid to roughly ASP + 4.3%. Note: HDD-CKD use is bundled into ESRD PPS, NOT paid per-mg.

How does Venofer compare to other IV irons?

Venofer (J1756, iron sucrose, $0.223/mg) is the IV iron workhorse for HDD-CKD because it can be given as a slow IV push during a dialysis session. Trade-off: it requires multiple visits (typically 5–10 doses) to reach a therapeutic 1,000 mg. Single-dose competitors include Injectafer (J1439, ferric carboxymaltose, 750 mg × 2 doses, $1.103/mg) and Monoferric (J1437, ferric derisomaltose, 1,000 mg single-dose, ~$1.05/mg) — higher per-mg cost but fewer infusion visits. Feraheme (Q0138/Q0139, 510 mg × 2, Boxed Warning) and INFeD (J1750, requires test dose) round out the class.

What are the indications for Venofer?

Venofer is FDA-approved for the treatment of iron-deficiency anemia (IDA) in adult and pediatric (≥2 yr) patients with chronic kidney disease, including hemodialysis-dependent (HDD-CKD), non-dialysis-dependent (NDD-CKD), and peritoneal dialysis-dependent (PDD-CKD). Off-label use for non-CKD IDA (e.g., heavy menstrual bleeding, post-bariatric, IBD-associated anemia) is common but not FDA-approved — these claims face higher prior-auth scrutiny and may require ferritin/TSAT documentation supporting iron deficiency.
