💊 About Micafungin DRUG GUIDE

Micafungin is used to treat several serious infections caused by Candida (a type of yeast), including candidemia (Candida in the bloodstream), acute disseminated candidiasis (widespread Candida infection), Candida peritonitis (Candida infection in the abdomen), Candida abscesses, and esophageal candidiasis (Candida infection of the esophagus/swallowing tube).

These uses apply to adults and most pediatric patients.Micafungin is also used to prevent Candida infections in adults and pediatric patients 4 months of age and older who are undergoing hematopoietic stem cell transplantation (HSCT).

Micafungin in Sodium Chloride Injection is only appropriate when a dose of exactly 50 mg, 100 mg, or 150 mg is needed; if a different dose is required, an alternative micafungin formulation should be used.

🧮 Dosing & billing-units calculator HCPCS UNITS

One billing unit of J2248 = 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 J2248 WITH EST. MEDICARE PAY

35 NDCs map to J2248. Bill units = how many HCPCS units one package represents. Est. pay / pkg = payment limit ($0.180/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 J2248 is utilized CMS · BY PROVIDER · 2024

Medicare Part B services for this code by the rendering provider's state — 89,401 services across 2 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.

⚠️ 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.

❓ J2248 billing FAQ

What is HCPCS code J2248?
J2248 is a HCPCS Level II J-code used to bill Injection, micafungin sodium, 1 mg under Medicare Part B and most medical (not pharmacy) benefits.
What is the billing unit for J2248?
One unit of J2248 represents 1 MG. Report the number of units equal to the dose administered divided by 1 MG.
How many units of J2248 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 J2248?
The Medicare Part B payment limit is $0.180 per unit (Q3 2026), based on ASP + 6%. After the 2% sequester the effective payment is about $0.176 per unit. Payment limits are revised quarterly.
Which NDCs bill under J2248?
35 NDCs currently map to J2248 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 J2248 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.
