Entyvio and the IBD biologic class
Entyvio (vedolizumab) bills under J3380, 1 mg per billing unit, from Takeda. It is a gut-selective integrin receptor antagonist for moderately to severely active ulcerative colitis and Crohn's disease. No vedolizumab biosimilar exists.
Payers frequently require a different product first: 24 of the 30 commercial payers in the Clearance corpus require another product before they authorize Entyvio, usually a trial of conventional therapy followed by a TNF inhibitor such as infliximab, adalimumab or golimumab, or the plan's preferred infliximab biosimilar (see Coverage & access).
Vials and NDCs
| Vial | Strength | NDC (11-digit, claim form) |
|---|---|---|
| 300 mg | Lyophilized powder, reconstituted with 4.8 mL and diluted into 250 mL | 64764-0300-20 |
One vial size covers every infusion. Every dose, induction or maintenance, draws exactly one 300 mg vial, so the billing-units calculator always returns 300 units with nothing discarded.
| Brand | HCPCS | Maker | Generic |
|---|---|---|---|
| Entyvio (IV) | J3380 | Takeda | vedolizumab |
| Remicade | J1745 | Janssen | infliximab |
| Stelara (IV induction) | J3358 | Janssen | ustekinumab |
| Skyrizi (IV induction) | J2327 | AbbVie | risankizumab-rzaa |
| Simponi Aria | J1602 | Janssen | golimumab |
This reference does not recommend one IBD biologic over another. The payer's own step-therapy rule, not a clinical preference, decides which product a given patient can start on.
Entyvio dosing
Vedolizumab uses the same 300 mg dose for both indications: induction infusions at weeks 0, 2 and 6, then one every 8 weeks. Every infusion draws exactly one 300 mg vial, so JZ applies on every infusion and JW never does.
| Indication | Induction | Maintenance | Notes |
|---|---|---|---|
| Ulcerative colitis, moderately to severely active | 300 mg IV at week 0, week 2 and week 6 (each over about 30 minutes) | 300 mg IV every 8 weeks; discontinue if no therapeutic benefit by week 14 | One 300 mg vial per infusion: 300 units of J3380, no waste (JZ), 96365 alone for a 30-minute infusion. Week 14 is the label's own stopping point and the first reauthorization checkpoint at most payers. |
| Crohn's disease, moderately to severely active | 300 mg IV at week 0, week 2 and week 6 (each over about 30 minutes) | 300 mg IV every 8 weeks; discontinue if no therapeutic benefit by week 14 | Identical to the ulcerative colitis schedule. The corpus files Crohn's and UC as separate dxKeys (K50 and K51), and several payers write different step requirements for each. |
After the two IV doses at weeks 0 and 2, or any time after week 6 while on IV maintenance, a patient may switch to the subcutaneous 108 mg pen or prefilled syringe every 2 weeks, dosed under the pharmacy benefit; the first subcutaneous dose replaces the next scheduled infusion. The pen carries no HCPCS code, so a patient who switches leaves this chapter's buy-and-bill claims entirely (see Cost & financial access).
Infusion reactions and hypersensitivity
Entyvio carries no boxed warning. Infusion-related and hypersensitivity reactions are the safety signal the label calls out; its language, in full:
Pre-treatment documentation
- Consider evaluating for tuberculosis infection before the first dose; update immunizations according to current guidelines.
- No pre-medication is required by the label.
- Confirm the payer's step-therapy requirement, conventional therapy then often a TNF inhibitor or the plan's preferred infliximab biosimilar, before scheduling the first infusion (see Coverage & access).
- Document the week-14 response; most payers use it as the first reauthorization checkpoint.

Entyvio billing reference
HCPCS
J3380 bills 1 mg per unit. A 300 mg infusion — the same dose at every visit, induction or maintenance — is 300 units.
NDC
One package size, one code. See the vial table in Drug & products above. The 11-digit claim-form NDC is 64764-0300-20, and it does not change across the regimen, since every infusion draws exactly one 300 mg vial.
Administration
Administration is a single code, not a choice: Entyvio is a 30-minute therapeutic infusion, billed with 96365 alone. CPT 96365–96366 carries the complete code definitions.
| Code | When it applies for Entyvio |
|---|---|
96365 | Primary and only code. Every Entyvio infusion runs about 30 minutes ($67.14, Medicare PFS national non-facility, 2026). |
96366 | Not reached. Each additional hour beyond the first only applies to an infusion documented well past 30 minutes, which Entyvio's label does not call for. |
96413 | Not appropriate. Vedolizumab is not chemotherapy; 96413 is the wrong code family for an integrin receptor antagonist. |
Modifiers
JZ: required when no drug is discarded. JW: required for documented waste.
Every Entyvio infusion draws exactly one 300 mg vial, with nothing left over, so JZ applies on every infusion and JW never does. The billing-units calculator walks through that same vial math dose by dose.

Entyvio coverage
The Clearance corpus carries 30 payers and 458 rules for vedolizumab — the richest coverage corpus of any drug not yet clustered in this reference. Both indications are covered widely: a Crohn's disease and an ulcerative colitis rule set exist at all 30 payers.
- 28 of 30 commercial payer policy sets require prior authorization; 2 do not say clearly, so confirm those on the call
- 24 of 30 payers require another product first, usually a trial of conventional therapy followed by a TNF inhibitor or the plan's preferred infliximab biosimilar.
- 17 rules set site-of-care requirements, including Kaiser's non-hospital-setting rule and BCBS Michigan's default to self-administration.
- 24 rules set a reauthorization period, most commonly 12 months, and several check response as early as week 14.
- 23 rules prohibit combining Entyvio with another biologic or a JAK inhibitor.
Prior authorization, step therapy and reauthorization
Most payers require conventional therapy first: Anthem's ulcerative-colitis criteria require “an inadequate response to or is intolerant of conventional therapy (such as 5-Aminosalicylic acid products, systemic corticosteroids, or immunosuppressants [such as thiopurines])”, and BCBS Minnesota requires “a minimum 3-month* trial of conventional therapy” before either indication. Several payers then require a TNF inhibitor specifically: Capital Blue requires “a minimum 3-month trial of a TNF modifier such as adalimumab, certolizumab” for Crohn's disease, and CareFirst's ulcerative-colitis criteria require both “At least ONE conventional therapy option” and “At least ONE TNF-alpha inhibitor indicated for UC”.
Some payers name a preferred product directly: Blue Shield of California requires “Inadequate response or intolerable side effect with BSC-preferred agent [infliximab (Avsola or Inflectra)] or contraindication to preferred agent.” Centene's Crohn's disease criteria are similar in shape: a member must fail a 3-month trial of the infliximab biosimilars Inflectra or Renflexis, or have a history of failure of two TNF blockers, before Entyvio is authorized. Not every payer requires a step: BCBS Mississippi places IV vedolizumab in “Table 2: Medical Covered Agents (no step therapy requirement).”
Reauthorization runs on a documented-response clock more than a fixed calendar. BCBS Health Care Service Corporation sets the first review at “14 weeks,” and Capital Blue matches it: “Initial coverage will be provided for 14 weeks and may be renewed annually thereafter…” Most other payers set a first authorization of 12 months and renew on evidence of continued benefit; CareFirst requires members to “achieve or maintain positive clinical response,” and UnitedHealthcare states: “Reauthorization will be for no more than 12 months.”
ICD-10-CM by indication
Two codes, one per diagnosis, both covered at all 30 payers in the corpus.
| Code | Description | Notes |
|---|---|---|
K51.90 | Ulcerative colitis, unspecified, without complications | Moderately to severely active disease, matching the visit note. |
K50.90 | Crohn's disease, unspecified, without complications | Moderately to severely active disease, matching the visit note. |
Site of care and quantity limits
Kaiser's rule is the strictest of the seventeen: the drug must “be administered in a non-hospital setting,” while BCBS Michigan's rule points toward the pharmacy benefit instead: “The member will self-administer Entyvio unless clinically unable to do so” — a reference to the subcutaneous pen, not the IV infusion. CareFirst permits “the first two infusions… in the hospital outpatient setting” to establish tolerance before a stricter site applies, and BCBS Florida adds requirements when the infusion happens in a “hospital-affiliated outpatient setting.”
Twelve rules set a quantity limit, and most restate the label's own 300 mg dose rather than a stricter cap; several separately allow an every-4-week escalation the label itself does not define. BCBS Florida writes both: “The dosage does not exceed 300 mg IV every 8 weeks (if for CD or UC)”, and a separate rule permitting every 4 weeks. Regence caps a starting course at: “Up to 6 doses (six 300 mg infusions) in a 6-month period.”

Entyvio cost & financial access
Medicare ASP+6%: $20.949 / 1 mg · $6,284.70 / 300 mg. Administration (96365) allows $67.14 more, so the induction or maintenance claim allows $6,351.84 total; at 20% coinsurance with the Part B deductible met, the patient owes $1,270.37 ($1,256.94 drug plus $13.43 infusion).
7 doses a year (300 mg IV every 8 weeks after the week 0, 2 and 6 induction infusions (a maintenance year is about 6.5 infusions; the first year is 8)) at $6,351.84 per infusion — drug plus 96365 administration — total $44,462.88 before the sequester. That is the full annual drug-plus-administration cost for a patient staying on schedule, before benefits or assistance.
Every infusion, induction or maintenance, bills the same 300 mg claim: $6,351.84 allowed, drug plus 96365. The difference between the first year and a maintenance year is frequency, not dose: the first year adds the three induction infusions at weeks 0, 2 and 6 before the every-8-week schedule takes over, so it runs more infusions than a maintenance year of about 6.5.
Commercial plans pay a contracted rate that varies by payer and state; 37 of 37 payer price files in this site's data carry a J3380 rate. Aetna's all-states commercial median is $21.72 per unit, close to the $20.949 ASP-based Medicare rate. At 300 units, that prices the drug portion of the infusion at $6,516.00, against Medicare's $6,284.70 for the drug alone.
Patient cost
Patient responsibility = payer allowed rate − benefits adjustment − assistance. Every Entyvio infusion bills the same $6,284.70 drug line, so the estimate does not depend on which visit in the regimen the encounter is — only on the patient's plan, remaining deductible and assistance.

Copay & financial assistance
EntyvioConnect Co-Pay Program covers a commercially insured patient's drug cost at $0 per dose, up to $20,000 a year; it does not cover the infusion administration, and it excludes Medicare, Medicaid, TRICARE, VA and other government plans. It is available for both the IV infusion and the subcutaneous pen.
No manufacturer free-drug program is on file. The IBD foundation funds in the bundle are HealthWell Inflammatory Bowel Disease ($2,100/year), TotalAssist Inflammatory Bowel Disease ($10,400/year), TotalAssist Ulcerative Colitis ($3,000/year) and HealthWell AutoImmune Medicare Access ($2,800/year); check each fund's current status on the funds list. The one open fund that matches J3380 in the bundle, HealthWell ANCA-Associated Vasculitis, covers a different disease and does not apply to a Crohn's or ulcerative colitis diagnosis.
Common Entyvio errors & fixes
| Error | Common cause | Fix |
|---|---|---|
| 96413 billed instead of 96365 | Chemotherapy administration code used for a non-oncology monoclonal antibody | Resubmit with 96365; vedolizumab is not chemotherapy. |
| Step therapy not documented before submission | Payer requires conventional therapy, then often a TNF inhibitor or the plan's preferred infliximab biosimilar, before Entyvio | Confirm and document the payer's step-therapy requirement before scheduling (see Coverage & access). |
| Site-of-care mismatch | Infusion given in a hospital-outpatient setting when the payer requires a non-hospital or home setting | Confirm the payer's site-of-care rule before scheduling; some payers permit only the first two infusions in a hospital outpatient setting. |
| Reauthorization submitted without response documentation | Renewal request relies on the calendar alone | Attach documentation of continued clinical benefit; several payers check in as early as week 14. |
| Indication code mismatched to the visit note | K50.90 (Crohn's disease) and K51.90 (ulcerative colitis) billed interchangeably | Confirm the diagnosis code on the claim matches the documented indication. |
| Entyvio billed alongside another biologic or a JAK inhibitor | Combination rule prohibits concurrent use (23 rules in the corpus) | Confirm no overlapping biologic or JAK-inhibitor therapy before submitting. |
| Subcutaneous pen billed with a HCPCS code | The pen has none; it is a pharmacy-benefit product, not a buy-and-bill drug | Route the pen through the pharmacy benefit, not a medical claim. |
Frequently asked questions
What is the J code for Entyvio?
Entyvio (vedolizumab) bills under HCPCS J3380, 1 mg per billing unit. A 300 mg infusion — the same dose at every visit, induction or maintenance — is 300 units. J3380 carries the JZ modifier on every claim, since one 300 mg vial supplies the full dose with nothing discarded.
Is Entyvio billed with 96365 or 96413?
96365. Entyvio is a 30-minute therapeutic infusion, and 96365 (therapeutic infusion, initial hour) is the correct administration code. 96413 is chemotherapy administration, the wrong code family for a gut-selective integrin receptor antagonist, and 96366 (each additional hour) does not apply at Entyvio's 30-minute infusion time.
How many units is 300 mg of Entyvio?
300 units. J3380 bills 1 mg per unit, so a 300 mg infusion — every dose in the regimen, induction or maintenance — divides evenly into 300 units, drawn from one 300 mg vial with nothing discarded. Bill the JZ modifier, since no drug is wasted.
What is the dosing for vedolizumab by indication?
Entyvio uses the same 300 mg dose for both indications: induction infusions at weeks 0, 2 and 6, then every 8 weeks:
- Ulcerative colitis = 300 mg every 8 weeks
- Crohn's disease = 300 mg every 8 weeks
Does Entyvio need a JW modifier?
No, not on the labeled 300 mg dose. One 300 mg vial supplies the full dose at every infusion, so nothing is discarded and JZ applies every time instead.
How often is Entyvio billed after induction?
Every 8 weeks. Induction runs three infusions at weeks 0, 2 and 6, and the maintenance dose then continues on an 8-week interval; the label's only stopping rule is no evidence of therapeutic benefit by week 14.
Does Entyvio require prior authorization?
Usually. 28 of the 30 commercial payers in the Clearance corpus require prior authorization, and 24 of the 30 also require another product first, most often a trial of conventional therapy followed by a TNF inhibitor or the plan's preferred infliximab biosimilar.
