💊 About Potassium Chloride DRUG GUIDE

Potassium chloride is used to treat hypokalemia — low potassium levels in the blood — with or without a related acid-base imbalance called metabolic alkalosis.

It is also used to prevent hypokalemia in people at high risk, such as those taking certain heart medications (digitalis) or those with significant heart rhythm problems.Oral extended-release tablets and capsules are also indicated for hypokalemia related to digitalis toxicity and a rare condition called hypokalemic familial periodic paralysis.

Potassium Chloride Injection is used when potassium levels are too low and oral treatment is not an option, and is specifically intended for fluid-restricted patients who need potassium supplementation.

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 J3480 = 2 meq. Enter a regimen to convert dose → billing units and project a full course.

Dose per administration (meq) Frequency — every days Number of doses NDC / package billed (optional)

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 J3480 WITH EST. MEDICARE PAY

63 NDCs map to J3480. Bill units = how many HCPCS units one package represents. Est. pay / pkg = payment limit ($0.136/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.

🗺️ Where J3480 is utilized CMS · BY PROVIDER · 2024

Medicare Part B services for this code by the rendering provider's state — 140,454 services across 39 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.

❓ J3480 billing FAQ

What is HCPCS code J3480?

J3480 is a HCPCS Level II J-code used to bill Injection, potassium chloride, per 2 meq under Medicare Part B and most medical (not pharmacy) benefits.

What is the billing unit for J3480?

One unit of J3480 represents 2 MEQ. Report the number of units equal to the dose administered divided by 2 MEQ.

How many units of J3480 should I bill?

Divide the dose administered by the code's unit size (2 MEQ) 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 J3480?

Which NDCs bill under J3480?

63 NDCs currently map to J3480 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 J3480 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.
