📋 J3375 summary

💊 About Vancomycin DRUG GUIDE
Vancomycin is used to fight serious bacterial infections caused by certain hard-to-treat bacteria, including methicillin-resistant Staphylococcus aureus (MRSA).
When given intravenously (by IV), it treats conditions like septicemia (a serious bloodstream infection), infective endocarditis (infection of the heart valves), skin and skin structure infections, bone infections, and lower respiratory tract infections.When taken by mouth — as capsules or oral solution (brands include Vancocin and Firvanq) — vancomycin treats Clostridioides difficile-associated diarrhea (C.
diff) and staphylococcal enterocolitis (a gut infection caused by Staphylococcus aureus).
It's important to know that the oral form does not work for bloodstream or other serious infections, and the IV form does not work for C.

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 J3375 = 10 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 J3375 WITH EST. MEDICARE PAY
15 NDCs map to J3375. Bill units = how many HCPCS units one package represents. Est. pay / pkg = payment limit ($0.142/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.

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.

⚠️ 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.
