Article summary

TL;DR

Visa and Mastercard both flag merchants at 1.5% in 2026, but an online pharmacy's acquirer watches much earlier: Visa makes it check pharmacy disputes daily. Pharmacy disputes come from card holds read as charges, orders charged then refused, refills billed before shipping and unrecognized descriptors. Capturing only after approval, billing refills on ship day and alerts prevent most of them.

Visa's US threshold is 1.5% of settled transactions, fraud plus disputes, since April 1, 2026, with at least 1,500 cases a month.
Mastercard's Excessive Chargeback Merchant level starts at 1.5% and 100 chargebacks, as reported by Chargeback Gurus (October 21, 2025).
From day 31, the acquirer of a Tier 1 merchant, such as a pharmacy, compares its daily disputes with its normal activity (Visa Core Rules, October 24, 2026).
Disputes resolved through a pre-dispute solution are excluded from Visa's count.
Card statements don't always tell an authorization from a charge, which "can sometimes confuse customers" (Stripe).

This guide is part of our hub on online pharmacy payment processing. The general guide, for any business: chargebacks. Brands that want the prescription side run for them can apply to Tagada Rx, a stack with storefront, doctors, pharmacy and payments.

The thresholds in 2026

	Visa (VAMP)	Mastercard (ECM)
Counted	Fraud reports (TC40) plus disputes (TC15)1	Chargebacks
Divided by	Settled card-not-present transactions, same month1	Transactions, previous month3
Threshold	1.5% in the US since April 1, 2026 (2.2% before)1	1.5%2
Minimum	1,500 fraud reports and disputes a month1	100 chargebacks a month2
Higher tier	Not covered here	HECM: 3% and 3002

Example

4,000 settled orders in a month, 50 disputes and 20 fraud reports. Visa ratio = 70 ÷ 4,000 = 1.75%. That's over 1.5% but far under Visa's 1,500-case minimum, so no Visa program. Your acquirer still sees it the next morning.

1.5%

Visa VAMP threshold for US merchants since April 1, 2026

1,500

Fraud reports and disputes a month before Visa's threshold applies

100

Chargebacks a month before Mastercard's ECM level applies

Day 31

From then, a Tier 1 merchant's acquirer checks its disputes daily

Tagada follows Visa and Mastercard rules and the laws that apply to payments. Program details: chargeback monitoring programs.

Why pharmacies are watched earlier

The thresholds above are the floor. Pharmacy acquirers carry extra network obligations, so their own tolerance is lower.

Visa, daily
From day 31 of a Tier 1 merchant, the acquirer tracks volume, average ticket, transactions and disputes every day against normal activity4.
Mastercard, yearly
The acquirer re-verifies the pharmacy's legality at least every 12 months5; a dispute pattern weighs on that review.
Mastercard BRAM
Its Business Risk Assessment and Mitigation program "investigates Merchants referred to Mastercard as potentially engaging in illegal or brand-damaging Transactions"5.

Why online pharmacy customers dispute

Cause	Typical Visa code6	Prevention
The card hold looks like a charge for an order that never shipped	13.1 Merchandise/Services Not Received	Say "authorized, not charged" at checkout; void fast7
Prescription refused, but the card was already charged	13.1 or 13.3	Capture only after approval; void instead of refunding
Refill charged, patient forgot or cancelled	13.2 Canceled Recurring Transaction	Reminders, easy cancellation8 9; bill on ship day
Late or lost shipment	13.1	Tracking emails; proactive refund when a delay is certain
Doesn't recognize the charge	Fraud codes	Pharmacy name in the descriptor, support contact
Card used by someone else	10.4 Other Fraud, Card-Absent	3D Secure, device data; Compelling Evidence 3.010

AuthorizationHold read as a charge: say authorized, not charged
Prescription checkRefused: void the hold, don't charge
CaptureOnly after approval
ShippingLate or lost: tracking emails, proactive refund
RefillRemind first, bill on ship day

Each step has its own dispute, and its own fix.

Visa reason codes via Chargeback.io, March 10, 2026; Stripe Docs, card holds.

Prevention that works

Authorize, verify, then capture. Nothing is charged before the prescription is approved: how to require a prescription before checkout.
Void refused orders instead of refunding them; the hold disappears from the statement.
Bill refills on ship day, not on a calendar date, so no one pays for an order that hasn't left.
Remind before each refill on cycles of 6 months or less (Mastercard) and before trials end, at least 7 days ahead (Visa)8 9.
Cancellation online, confirmed by email8 9.
A recognizable descriptor: pharmacy name and phone. See billing descriptor.
Fraud controls: 3D Secure and device data on new customers and high-value orders: fraud prevention and 3D Secure for online pharmacies.

Alerts setup

Alerts warn you of a dispute before it's filed, so you can refund and keep it out of the count. Visa excludes disputes resolved through a pre-dispute solution1.

Ask your processor which alert services it connects: Visa Rapid Dispute Resolution, Ethoca, Verifi.
Set auto-refund rules for low-value orders, and review high-value ones by hand.
Cancel the refill at the same time as the refund, or the next charge becomes the next dispute.
Track alerts by cause: they show which step of the flow leaks.

Setup and costs in detail: chargeback alerts for online pharmacies.

Respond or refund?

Situation	Best move	Why
Alert received before a dispute	Refund	Excluded from Visa's count1
Fraud dispute, with matching IP, device and past undisputed orders	Respond with CE 3.0 evidence	Visa's 10.4 remedy10
"Not received" with delivery confirmation	Respond with tracking	Your records decide the case
Refill disputed, and you can prove consent, reminder and no cancellation	Respond	Same
Patient cancelled, or the hold was never voided	Accept and fix the flow	You'd lose, and pay twice

An alert before a disputeThe patient called the bank but no chargeback is filed yet.Refund now: resolved pre-disputes stay out of Visa's count.
A 13.1 'not received' disputeThe patient says the order never arrived, or reads a hold as a charge.Respond with tracking if it shipped; void the hold if it didn't.
A 10.4 fraud disputeThe cardholder says they didn't order.Respond with CE 3.0 evidence: IP, device, past undisputed orders.

What never to do

Don't spread volume across accounts to stay under thresholds: Stripe prohibits evasion of chargeback monitoring11, and networks treat it the same.
Don't capture before approval to secure revenue: every refused prescription becomes a refund or a dispute.
Don't reprocess a disputed transaction.

How Tagada helps

Capture after approval, rebill on ship day

Tagada Rx builds this flow into a telehealth stack with storefront, doctors, pharmacy and payments, open by application to a selected group of brands14.

Capture or void, never a refund: approval captures the hold, a decline voids it12.
Rebill on ship day: "No 'charged but never shipped' revenue"12.
Native 3DS2, device intelligence and a rules engine, plus block rules on IPs, emails, card patterns and customers13.
Clear checkout copy: the docs require the storefront to say the hold is not clinical approval12.

Frequently asked questions

What is the chargeback threshold for online pharmacies in 2026?

Visa monitors US merchants at 1.5% of settled transactions, fraud reports plus disputes, with at least 1,500 cases a month, since April 1, 2026. Mastercard starts at 1.5% and 100 chargebacks. A pharmacy's acquirer reviews disputes daily, so its own limit is usually lower.

How do I calculate my chargeback ratio?

For Visa: fraud reports plus disputes in the month, divided by settled card-not-present transactions the same month. For Mastercard: chargebacks in the month, divided by the previous month's transactions. Track both by product and by refill versus first order.

Why do online pharmacies get chargebacks?

Mostly from the payment flow, not fraud: holds read as charges, orders charged then refused, refills billed before shipping, and descriptors patients don't recognize. Capturing after approval, billing on ship day and clear descriptors fix most of them.

Should I fight every pharmacy chargeback?

No. Respond when your records prove consent and delivery, or when Visa's Compelling Evidence 3.0 applies to a fraud claim. Accept cases where the patient cancelled or the hold wasn't voided, and fix that step.

Do chargebacks affect my LegitScript or NABP accreditation?

We found no network rule that ties accreditation to dispute ratios. The rules do keep the acquirer watching: daily under Visa Tier 1 and a legality review every 12 months under Mastercard. A bad pattern can cost you the merchant account first.
