💊 About Esmolol DRUG GUIDE

Esmolol injection is used to quickly slow a dangerously fast heart rate in adults with supraventricular tachycardia (SVT) — a type of rapid heart rhythm that starts above the heart's lower chambers — including atrial fibrillation and atrial flutter.

It is also used for noncompensatory sinus tachycardia (a fast heart rate that needs to be treated, not just monitored).Esmolol injection is also approved for the short-term treatment of tachycardia (fast heart rate) and high blood pressure that can occur during or just after surgery — for example, during anesthesia, tracheal intubation, or in the postoperative period.

It is intended for short-term use only, and is not recommended to prevent these events before they happen.

🧮 Dosing & billing-units calculator HCPCS UNITS

One billing unit of J1805 = 10 mg. Enter a regimen to convert dose → billing units and project a full course.

Dose per administration (mg) 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 J1805 WITH EST. MEDICARE PAY

28 NDCs map to J1805. Bill units = how many HCPCS units one package represents. Est. pay / pkg = payment limit ($0.230/unit) × that package's bill units.

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 J1805 is utilized CMS · BY PROVIDER · 2024

Medicare Part B services for this code by the rendering provider's state — 166 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.

❓ J1805 billing FAQ

What is HCPCS code J1805?

J1805 is a HCPCS Level II J-code used to bill Injection, esmolol hydrochloride, 10 mg under Medicare Part B and most medical (not pharmacy) benefits.

What is the billing unit for J1805?

One unit of J1805 represents 10 MG. Report the number of units equal to the dose administered divided by 10 MG.

How many units of J1805 should I bill?

Divide the dose administered by the code's unit size (10 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 J1805?

The Medicare Part B payment limit is $0.230 per unit (Q3 2026), based on ASP + 6%. After the 2% sequester the effective payment is about $0.225 per unit. Payment limits are revised quarterly.

Which NDCs bill under J1805?

28 NDCs currently map to J1805 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 J1805 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.
