💊 About Argatroban DRUG GUIDE
Argatroban injection is used to prevent or treat blood clots in adults who have heparin-induced thrombocytopenia (HIT) — a serious condition where the blood thinner heparin causes the body to form dangerous clots instead of preventing them.It is also used as an anticoagulant during percutaneous coronary intervention (PCI) — a procedure to open blocked heart arteries — in adults who have HIT or are at risk for it.

The CMS payment limit is the Medicare Part B drug allowance (ASP + 6%, statutory). After the 2% federal sequester the effective payment is ≈ ASP + 4.3%; estimated ASP = payment limit ÷ 1.06. Source: CMS Medicare Part B Payment Limit File (quarterly), Q3 2026.

🧮 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.
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.

⚠️ 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.
