💊 About Cefazolin Injection DRUG GUIDE
Cefazolin Injection is used to treat bacterial infections in adults and children 1 month of age and older, including respiratory tract infections, urinary tract infections, skin and skin structure infections, biliary tract infections, bone and joint infections, genital infections (such as prostatitis and epididymitis), septicemia (a serious bloodstream infection), and endocarditis (infection of the heart's inner lining).It is also used in adult patients — and in pediatric patients aged 10 to 17 years for the premixed formulation — to help prevent infection around the time of surgery, particularly for procedures that carry a higher risk of postoperative infection.

🧮 Dosing & billing-units calculator HCPCS UNITS
One billing unit of J0689 = 500 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 J0689 WITH EST. MEDICARE PAY
3 NDCs map to J0689. Bill units = how many HCPCS units one package represents. Est. pay / pkg = payment limit ($1.290/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 J0689 is utilized CMS · BY PROVIDER · 2024
Medicare Part B services for this code by the rendering provider's state — 1,616 services across 3 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.
