About Tivdak FDA verified May 2026
First tissue factor-targeted antibody-drug conjugate; first FDA-approved drug specifically for recurrent/metastatic cervical cancer post-chemo.
Tivdak (tisotumab vedotin-tftv) is a tissue factor (TF)-directed antibody-drug conjugate developed jointly by Genmab and Seagen (acquired by Pfizer in 2023). It pairs an anti-tissue factor monoclonal antibody with the cytotoxic agent monomethyl auristatin E (MMAE) via a protease-cleavable linker. Once internalized by tumor cells expressing tissue factor, MMAE is released and disrupts microtubules, triggering apoptosis.
FDA granted accelerated approval September 20, 2021 based on the single-arm innovaTV 204 phase 2 trial. Full traditional approval was granted April 29, 2024 based on the ENGOT-cx12/innovaTV 301 randomized phase 3 confirmatory trial, which demonstrated overall survival benefit vs investigator-choice chemotherapy. Tivdak is the first FDA-approved drug specifically indicated for recurrent or metastatic cervical cancer with disease progression on or after chemotherapy — an area with no prior approved second-line standard of care.
Dosing & unit math FDA label Apr 2024
Weight-based 2 mg/kg q3w with a 200 mg per-dose cap. Bill the actual mg administered.
Adult dosing
- 2 mg/kg IV every 3 weeks until disease progression or unacceptable toxicity
- Maximum 200 mg per dose for patients weighing more than 100 kg
- Round dose to nearest mg per FDA label
- 1 mg = 1 unit of J9273; bill the actual mg administered (not vial size)
- Approximately 17 cycles per year on a strict q3w schedule (52 / 3)
Reconstitution & preparation
- Reconstitute each 40 mg vial with 8 mL Sterile Water for Injection → 5 mg/mL solution
- Withdraw calculated dose volume; further dilute in 0.9% NaCl IV bag
- Final concentration: 0.4–1.8 mg/mL
- Administer over 30 minutes via dedicated IV line with 0.2–0.22 micron in-line filter
- Single-dose vial — discard unused portion (never pool partial vials)
Worked example — 70 kg patient
70 kg × 2 mg/kg = 140 mg per dose
Vials needed: 140 / 40 = 3.5 → round up to 4 vials (160 mg drawn)
Discarded: 160 - 140 = 20 mg waste
# Claim lines
Drug administered: J9273 × 140 units (no modifier on this line; or JZ-equivalent)
Drug discarded: J9273 × 20 units with JW modifier
Admin: 96413 (30-min chemo IV)
# Cost (Q2 2026 ASP+6%)
Administered: 140 × $196.121 = ~$27,456.94
Wasted (also reimbursable): 20 × $196.121 = ~$3,922.42
Total drug cost per dose: ~$31,379.36
Worked example — 110 kg patient (capped)
110 kg × 2 mg/kg = 220 mg → cap at 200 mg (max per dose)
Vials needed: 200 / 40 = exactly 5 vials — no waste
# Claim lines
Drug administered: J9273 × 200 units with JZ modifier (no waste)
Admin: 96413

Ocular toxicity — BOXED WARNING FDA label verified May 2026
The defining safety feature of Tivdak. Every infusion has an ophthalmic protocol attached to it.
Mandatory ophthalmology workflow
- Baseline ophthalmologic exam by an eye care provider before the first dose, including visual acuity and slit-lamp examination
- Repeat exam before every cycle (q3w) and as clinically indicated for new or worsening symptoms
- Patient education at every visit: avoid contact lenses, use eye drops as prescribed, report any vision changes immediately
- Have a referral pathway to an eye care provider for grade 2+ events — do not wait for next scheduled cycle
Dose modification for ocular AEs
| Severity | Action |
|---|---|
| Grade 1 (mild) | Continue dosing; treat symptoms |
| Grade 2 | Withhold until grade 1 or baseline; resume at same dose |
| Grade 3 | Withhold until grade 1 or baseline; resume at reduced dose; permanently discontinue if recurrent grade 3 |
| Grade 4 / corneal perforation | Permanently discontinue |
Mandatory eye care protocol FDA label verified May 2026
Required at every infusion. Document each step in the chart for payer audits.
Per-infusion eye care checklist
- Pre-infusion (immediately before): Administer ophthalmic vasoconstrictor eye drops to both eyes per label (typically a single drop each eye 5–10 min before infusion).
- Pre-infusion (immediately before): Administer ophthalmic corticosteroid eye drops to both eyes per institutional protocol.
- During infusion: Apply cooling eye pads to both closed eyelids for the entire 30-minute infusion AND continue for approximately 30 minutes after infusion ends. Replace pads as needed to maintain cooling.
- During and after infusion: Continue ophthalmic corticosteroid drops as prescribed for the remainder of the cycle.
- Throughout therapy and 30 days after the last dose: Patient uses preservative-free ophthalmic lubricants 4–6 times daily in both eyes.
- Throughout therapy: NO contact lens use unless directed by an eye care provider.
- Every cycle: Ophthalmologist exam BEFORE infusion (visual acuity + slit-lamp). Document result in the chart.

Modifiers CMS verified May 2026
JW — required on virtually every Tivdak claim
Tivdak ships only as 40 mg single-dose vials, but dosing is weight-based at 2 mg/kg. Most patient weights produce a calculated dose that is not a perfect 40 mg multiple, so partial-vial waste is the rule. CMS requires the JW modifier on a separate claim line reporting the discarded units, and one of JZ or JW must be on every J9273 claim per the July 1, 2023 single-dose container policy.
JZ — only when calculated dose lands exactly on a 40 mg multiple
Use JZ only when no drug is discarded. For Tivdak that means the calculated 2 mg/kg dose is exactly 40, 80, 120, 160, or 200 mg — corresponding to patient weights of 20, 40, 60, 80, or 100+ kg (capped). Most adult patients will not hit those weights exactly.
| Patient weight | Calculated dose | Vials | Waste | Modifier(s) |
|---|---|---|---|---|
| 50 kg | 100 mg | 3 (120 mg) | 20 mg | JW (20 units) |
| 60 kg | 120 mg | 3 (120 mg) | 0 mg | JZ |
| 70 kg | 140 mg | 4 (160 mg) | 20 mg | JW (20 units) |
| 80 kg | 160 mg | 4 (160 mg) | 0 mg | JZ |
| 85 kg | 170 mg | 5 (200 mg) | 30 mg | JW (30 units) |
| >100 kg (capped) | 200 mg | 5 (200 mg) | 0 mg | JZ |
Modifier 25 — same-day E/M
Use modifier 25 on the E/M code when a significant, separately identifiable evaluation and management service is performed on the same day as infusion (e.g., toxicity assessment requiring management decisions). Routine pre-infusion clinical assessment is bundled.
340B modifiers (JG, TB)
For 340B-acquired Tivdak, follow your MAC's current 340B modifier policy. Pfizer's billing guide does not provide 340B-specific instructions.
ICD-10-CM — cervical cancer family FY2026 verified May 2026
Single indication: recurrent or metastatic cervical cancer with disease progression on or after chemotherapy. Use the most specific code supported by documentation.
| ICD-10 | Description | When to use |

Z85.41 | Personal hx of malignant neoplasm of cervix uteri | Use only for surveillance after disease control; not for active treatment |
Site of care & place of service Verified May 2026
Tivdak is generally administered in physician oncology offices, ambulatory infusion suites, oncology ASCs, or hospital outpatient infusion centers. The boxed ocular toxicity protocol does not require a specific site, but it does require an ophthalmology partnership (referral pathway) and the supply chain for cooling pads, vasoconstrictor, corticosteroid, and lubricant drops.

Step therapy
By definition, Tivdak's indication requires prior platinum-based chemotherapy (typically platinum + paclitaxel ± bevacizumab in 1L recurrent/metastatic). PA criteria thus build step therapy into the indication. After Tivdak, NCCN options include Keytruda (J9271, +chemo with bevacizumab in 1L recurrent/metastatic if PD-L1 CPS ≥1; mono in 2L+) and Jemperli (J9272, dMMR/MSI-H endometrial; off-label cervical).
NCCN positioning
NCCN Cervical Cancer Guidelines list Tivdak as a Category 2A preferred regimen for second-line treatment of recurrent or metastatic cervical cancer after platinum chemotherapy, regardless of PD-L1 status. This is the strongest non-biomarker-restricted second-line option in the guideline.

Common denials & how to fix them
| Denial reason | Common cause | Fix |
|---|---|---|
| Ophthalmology baseline exam not documented | PA submitted without ophthalmology pre-treatment evaluation | Schedule ophthalmology exam BEFORE first PA submission. Include the exam note + visual acuity in PA packet. |
| JW waste missing | Wasted Tivdak (partial vial) not reported on a separate claim line | Add JW line for discarded units. Given $196.121/mg, missing waste = $3,000–$6,000 unbilled per dose. |
| Wrong admin code (96365) | Therapeutic IV billed instead of chemo IV | Resubmit with 96413. Tivdak (MMAE-bearing ADC) is chemo admin per CPT classification. |
| Prior chemo failure not documented | PA submitted without evidence of disease progression on/after platinum-based chemotherapy | Include prior chemotherapy regimen(s), dates, and documentation of progression (imaging, labs, clinical) in PA packet. |
| "Investigational" denial | Payer treating as accelerated approval (pre-April 2024) | Cite ENGOT-cx12 / innovaTV 301 phase 3 confirmatory data and FDA full approval (April 2024). Submit appeal with FDA approval letter. |
| Wrong NDC format | Vial-level NDC submitted without zero-pad | Use 11-digit padded NDC: 51144-0040-01 with N4 qualifier in 24A shaded area. |
| Site of care (HOPD) | HOPD administration after first 3 months on commercial plan with site-of-care UM | Move to office (POS 11) or AIC (POS 49). Submit medical necessity letter if HOPD required for ophthalmology coordination. |
| Dose exceeds 200 mg cap | Patient >100 kg billed at full 2 mg/kg without applying max cap | Cap dose at 200 mg per FDA label. Resubmit with 200 units (no JW since 5 vials = 200 mg exactly). |
Frequently asked questions
What is the HCPCS code for Tivdak?
Tivdak (tisotumab vedotin-tftv) is billed under HCPCS J9273 — "Inj tisotu
vedotin-tftv, 1 mg." Each milligram equals one billable unit. The drug ships in 40 mg lyophilized
single-dose vials (NDC 51144-040-01).
How many units do I bill for a Tivdak dose?
Bill the actual mg administered. Calculate 2 mg/kg of actual body weight, capped at 200 mg per dose for patients >100 kg. Example: a 70 kg patient receives 140 mg = 140 units of J9273; uses four 40 mg vials with 20 mg discarded — bill JW for 20 units of waste plus 140 units administered on a separate claim line.
What administration CPT do I use for Tivdak?
CPT 96413 — "Chemotherapy administration, IV infusion technique; up to 1 hour,
single or initial substance/drug." Tivdak's standard infusion is 30 minutes, fitting within the
1-hour window. As a complex monoclonal antibody-drug conjugate, it is billed under chemo admin codes
per AMA classification. Do NOT bill 96365.
Do I bill JZ or JW for Tivdak?
Bill JW on virtually every Tivdak claim. Because the only available vial is 40 mg and dosing is weight-based (2 mg/kg), partial-vial waste is the rule. Use JZ only when the calculated dose lands exactly on a 40 mg multiple (60, 80, 120, 160, 200 mg). One of JZ or JW must be on every J9273 claim per CMS's July 2023 single-dose container policy.
What is the boxed warning for Tivdak?
Tivdak carries a BOXED WARNING for ocular toxicity — severe vision changes, ulcerative keratitis, and conjunctival/corneal events. Baseline ophthalmology exam required before the first dose, then before every cycle. A mandatory eye care protocol must be followed: cooling eye pads during and 30 min after infusion, ophthalmic vasoconstrictor + corticosteroid drops per protocol, ophthalmic lubricants 4–6×/day, and NO contact lens use during therapy. See eye care protocol.
What is the Medicare reimbursement for J9273?
For Q2 2026, the Medicare Part B payment limit for J9273 is $196.121 per mg (ASP + 6%). A 140 mg dose (typical 70 kg patient) reimburses at approximately $27,456.94 per infusion; a max-cap 200 mg dose at $39,224.20. Annualized Medicare cost (q3w cycles, ~17 doses/year): approximately $466,000 for a 70 kg patient, plus reimbursable JW waste.
What is Tivdak approved for?
Tivdak is approved for adult patients with recurrent or metastatic cervical cancer with disease progression on or after chemotherapy. Initial accelerated approval was granted September 2021 (innovaTV 204 single-arm trial). Full traditional approval was granted April 2024 based on the ENGOT-cx12/innovaTV 301 confirmatory phase 3 trial showing OS benefit. It is the first FDA-approved drug specifically for this indication and the first tissue factor-targeted ADC.
How does Tivdak compare to other ADCs?
Tivdak is one of six FDA-approved oncology antibody-drug conjugates. It uses MMAE (monomethyl auristatin E) as its cytotoxic payload — the same payload as Adcetris (J9042, anti-CD30, Hodgkin), Polivy (J9309, anti-CD79b, DLBCL), and Padcev (J9177, anti-Nectin-4, urothelial). Enhertu (J9358) and Trodelvy (J9317) use different payloads (deruxtecan, govitecan). All MMAE-payload ADCs share peripheral neuropathy as a class effect. Only Tivdak carries a boxed ocular toxicity warning. See ADC class comparison.
