💊 About Furosemide DRUG GUIDE
Furosemide tablets and oral solution are used in adults and children to treat edema (fluid buildup) caused by congestive heart failure, cirrhosis of the liver, and kidney disease, including nephrotic syndrome.
In adults, oral furosemide is also used to treat high blood pressure, alone or alongside other blood pressure medications.Furosemide injection is reserved for patients who cannot take oral medicine or for emergency situations such as acute pulmonary edema (sudden dangerous fluid in the lungs).
Furoscix (subcutaneous injection) is specifically indicated for edema in adults with chronic heart failure or chronic kidney disease, including nephrotic syndrome, and in pediatric patients weighing at least 43 kg.
Lasix Onyu (subcutaneous injection) is indicated for edema in adults with chronic heart failure only.

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 J1938 = 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 J1938 LEAST EXPENSIVE FIRST
66 NDCs map to J1938. Bill units = how many HCPCS units one package represents. Est. pay / pkg = payment limit ($0.018/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. A blank patient count means fewer than 11 people — CMS hides counts that small to protect privacy. Source: CMS Medicare Quarterly Part B Spending by Drug (data.cms.gov), updated quarterly.

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.

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.

📊 What bills under J1938
J-codes are billing codes often used for drugs billed under the medical benefit. This connects the billing code to the NDC package records it covers, by ingredient and labeler.

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.
❓ J1938 billing FAQ
What is HCPCS code J1938?
J1938 is a HCPCS Level II J-code used to bill Inj, furosemide, 1 mg under Medicare Part B and most medical (not pharmacy) benefits.
What is the billing unit for J1938?
One unit of J1938 represents 1 MG. Report the number of units equal to the dose administered divided by 1 MG.
How many units of J1938 should I bill?
Divide the dose administered by the code's unit size (1 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 J1938?
The Medicare Part B payment limit is $0.018 per unit (Q3 2026), based on ASP + 6%. After the 2% sequester the effective payment is about $0.018 per unit. Payment limits are revised quarterly.
Which NDCs bill under J1938?
66 NDCs currently map to J1938 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 J1938 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.
