💊 About Carboplatin Injection DRUG GUIDE
Carboplatin Injection is used to treat advanced ovarian cancer.
It is approved for use as part of an initial combination chemotherapy regimen — one established combination pairs it with cyclophosphamide.
It has also been used as a single agent in patients with recurrent ovarian cancer after prior treatment.Because two brands are available — Kyxata and Paraplatin — your care team will specify which product you receive.
Both are given by intravenous (IV) infusion in a clinical setting under the supervision of a physician experienced in cancer chemotherapy.

🧮 Dosing & billing-units calculator HCPCS UNITS
One billing unit of J9045 = 50 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 J9045 WITH EST. MEDICARE PAY
49 NDCs map to J9045. Bill units = how many HCPCS units one package represents. Est. pay / pkg = payment limit ($3.153/unit) × that package's bill units.

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 J9045 is utilized CMS · BY PROVIDER · 2024
Medicare Part B services for this code by the rendering provider's state — 429,420 services across 49 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.
❓ J9045 billing FAQ
What is HCPCS code J9045?
J9045 is a HCPCS Level II J-code used to bill Injection, carboplatin, 50 mg under Medicare Part B and most medical (not pharmacy) benefits.
What is the billing unit for J9045?
One unit of J9045 represents 50 MG. Report the number of units equal to the dose administered divided by 50 MG.
How many units of J9045 should I bill?
Divide the dose administered by the code's unit size (50 MG) 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 J9045?
The Medicare Part B payment limit is $3.153 per unit (Q3 2026), based on ASP + 6%. After the 2% sequester the effective payment is about $3.090 per unit. Payment limits are revised quarterly.
Which NDCs bill under J9045?
49 NDCs currently map to J9045 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 J9045 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.
