💊 About Phytonadione DRUG GUIDE

Phytonadione treats bleeding disorders caused by vitamin K deficiency or by drugs that interfere with how vitamin K works.

This includes low clotting-factor levels caused by blood thinners like warfarin (coumarin-type anticoagulants), certain antibiotics, and other drugs such as salicylates.It also treats hypoprothrombinemia (low prothrombin, a clotting protein) that results from conditions limiting vitamin K absorption — such as obstructive jaundice, ulcerative colitis, celiac disease, Crohn's disease (regional enteritis), intestinal resection, cystic fibrosis, or biliary fistula.

The injectable forms are additionally approved for preventing and treating vitamin K-deficiency bleeding in newborns.

The oral tablet (Mephyton and Phytonadione tablets) is approved for adults only.

🧮 Dosing & billing-units calculator HCPCS UNITS

One billing unit of J3430 = 1 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 J3430 WITH EST. MEDICARE PAY

17 NDCs map to J3430. Bill units = how many HCPCS units one package represents. Est. pay / pkg = payment limit ($3.253/unit) × that package's bill units.

⚠️ 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.
