💊 About Carmustine DRUG GUIDE

Carmustine injection is used as palliative therapy — either alone or combined with other chemotherapy drugs — for several brain tumors, including glioblastoma, brainstem glioma, medulloblastoma, astrocytoma, ependymoma, and metastatic brain tumors.

It is also used for multiple myeloma (in combination with prednisone), and for relapsed or refractory Hodgkin's lymphoma and Non-Hodgkin's lymphomas (in combination with other approved drugs).Gliadel — a dissolving wafer form of carmustine placed directly into the brain during surgery — is specifically indicated for newly diagnosed high-grade glioma (as an addition to surgery and radiation) and for recurrent glioblastoma (as an addition to surgery).

🧮 Dosing & billing-units calculator HCPCS UNITS

One billing unit of J9050 = 100 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 J9050 WITH EST. MEDICARE PAY

12 NDCs map to J9050. Bill units = how many HCPCS units one package represents. Est. pay / pkg = payment limit ($240.011/unit) × that package's bill units.

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.

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.

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.
