💊 About Dextrose / Heparin DRUG GUIDE
Heparin Sodium in 5% Dextrose Injection is used to prevent and treat serious blood clots.
This includes venous thrombosis (clots in the veins), pulmonary embolism (clots in the lungs), and clotting complications linked to atrial fibrillation (an irregular heart rhythm).
It is also used to treat disseminated intravascular coagulation (DIC), a dangerous condition where clotting and bleeding happen abnormally throughout the body.Heparin Sodium in 5% Dextrose Injection is also used to prevent clotting during heart and blood vessel surgery, to treat peripheral arterial embolism (clots blocking arteries in the limbs), and to keep blood from clotting during transfusions, heart-lung bypass procedures, and dialysis.

🧮 Dosing & billing-units calculator HCPCS UNITS
One billing unit of J1644 = 1,000 units. 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 J1644 LEAST EXPENSIVE FIRST
162 NDCs map to J1644. Bill units = how many HCPCS units one package represents. Est. pay / pkg = payment limit ($0.199/unit) × that package's bill units.

NDC→HCPCS mappings come from the CMS ASP NDC-HCPCS crosswalk; additional DME MAC / DMEPOS mappings come from PDAC and are labeled separately. NADAC from CMS (weekly). “Status” reflects the product's marketing / obsolete flag in the NDC directory. Presence or absence here does not determine Medicare coverage.

Provider-administered (Part B) spend, calculated for the whole HCPCS code (CMS does not publish Medicare spend per individual NDC). Self-administered use is covered under Part D instead. A blank patient count means fewer than 11 people — CMS hides counts that small to protect privacy. Source: CMS Medicare Quarterly Part B Spending by Drug (data.cms.gov), updated quarterly.
📈 Medicare Part B claims detail CMS PSPS · 2024
Calendar-year 2024 Medicare Part B fee-for-service activity for this HCPCS code, summed across all carriers, localities and specialties (CMS Physician/Supplier Procedure Summary). A “service” is one billed line/unit — not one claim — so counts run higher than claim counts.

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 J1644 is utilized CMS · BY PROVIDER · 2024
Medicare Part B services for this code by the rendering provider's state — 247,119 services across 28 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.
❓ J1644 billing FAQ
What is HCPCS code J1644?
J1644 is a HCPCS Level II J-code used to bill Injection, heparin sodium, per 1000 units under Medicare Part B and most medical (not pharmacy) benefits.
What is the billing unit for J1644?
One unit of J1644 represents 1000 UNITS. Report the number of units equal to the dose administered divided by 1000 UNITS.
How many units of J1644 should I bill?
Divide the dose administered by the code's unit size (1000 UNITS) 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 J1644?

Which NDCs bill under J1644?
162 NDCs currently map to J1644 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 J1644 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.
