💊 About Argatroban DRUG GUIDE

Argatroban is given through a vein to adults for two main purposes.

The first is to prevent or treat blood clots (thrombosis) in people with heparin-induced thrombocytopenia (HIT).

HIT is a reaction to heparin that causes a drop in platelets and a higher risk of clots.The second is as a blood thinner in adults with or at risk for HIT who are having percutaneous coronary intervention (PCI), a procedure to open blocked heart arteries.

🧮 Dosing & billing-units calculator HCPCS UNITS

One billing unit of J0899 = 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 J0899 WITH EST. MEDICARE PAY

2 NDCs map to J0899. Bill units = how many HCPCS units one package represents. Est. pay / pkg = payment limit ($1.214/unit) × that package's bill units.

⚠️ 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.
