Payment Insights & Benchmarks

Merchants in the Optometrists and Ophthalmologists MCC should expect a nuanced payment landscape, which may involve higher operational complexities compared to standard e-commerce. Understanding these dynamics can help manage costs and improve approval rates.

Payment methods

Cards: primary method, but face potential issues with high-ticket transactions leading to increased scrutiny.

  • Health savings accounts (HSAs) and flexible spending accounts (FSAs): often accepted, but require clear communication to customers.
  • E-wallets: gradually gaining traction, particularly for convenience in copayments.
  • Installment plans: popular for expensive procedures, enhancing affordability but requiring careful management of payments.

Authentication & security

Strong customer authentication (SCA) protocols are typically required for e-commerce transactions.

  • Fraud detection measures should be in place to handle high-ticket items that can attract fraud attempts.
  • Utilization of 3D Secure (3DS) can enhance security but may affect user experience if not implemented well.

Benchmarks (indicative, not guaranteed)

MDR: generally higher than standard e-commerce due to the nature of healthcare transactions.

  • Rolling reserves: may be required by some PSPs, often in the range of mid-single digits percent.
  • Settlement times: typically longer, averaging 5-10 business days.
  • Chargeback ratios: can be higher than retail averages, particularly for elective procedures.
  • Approval rates: may vary widely; high-ticket transactions tend to have lower rates.

Key metrics to monitor

Transaction approval rates, focusing on high-ticket items.

  • Chargeback rates by procedure type to identify potential fraud trends.
  • Customer payment method preferences and shifts over time.
  • Reason codes for declines to improve understanding of payment friction.
  • Average invoice values to help manage cash flow and operational readiness.

Risk & Compliance

Merchants under this MCC are subject to considerable scrutiny due to the sensitive nature of health-related transactions. PSPs and acquirers impose stringent controls, demanding that merchants proactively manage risks related to chargebacks, fraud, as well as AML/KYC compliance.

Chargebacks & fraud

Instances of friendly fraud (e.g., patients disputing charges for services rendered) are common, along with possible payment disputes regarding insurance coverage.

  • Fraudulent claims may involve the use of stolen insurance information or identities for unauthorized treatments.
  • Mitigation tools such as velocity checks, device fingerprinting, and detailed patient record management can help minimize risks.

AML/KYC expectations

Robust identity verification (IDV) procedures are essential, including checks against sanctions lists and politically exposed persons (PEPs).

  • Source-of-funds verification is expected, particularly for high-cost procedures or treatments.
  • Manual review triggers include upfront payment patterns for expensive services or frequent high-value transactions from the same account.

Operational red flags

Lack of transparency regarding the ownership structure of the practice could raise alarms with PSPs.

  • Absence of detailed service descriptions and pricing can lead to misunderstandings and disputes.
  • Failure to maintain proper patient records or delayed claim submissions may attract scrutiny.
  • Inadequate communication about refund policies for services can result in chargebacks and reputational damage.

It's common for networks to require documentation to verify practitioner credentials and adherence to regional healthcare laws.

Alternative MCC Codes

Merchants often confuse this MCC with other categories. The table below shows which codes are related, why they are confused, and what risks misclassification brings.

MCC How it is used Why confused When acceptable What is risky
8041 Offices and Clinics of Dentists “We provide multiple healthcare services” Dental clinics providing optometry services Misclassifying as a dentist if not providing dental care
8011 Doctors and Physicians “We are in the healthcare field” General medical practice or specialists Treating optometric services as general physician care
8043 Offices of Other Health Practitioners “We operate within the health industry” Therapists and alternative health practitioners Confusing with unconventional practices lacking proper permits
8322 Individual and Family Services “We provide comprehensive health services” Counseling services related to eye health Misclassifying non-medical services as healthcare

Rule of thumb for merchants:

Ensure your business activities align specifically with the services associated with MCC 8042. If your primary focus is on eye care and vision correction, use this code; otherwise, using an alternative MCC can lead to compliance issues and potential financial penalties.

Best Practices for Merchants

Merchants in the optometry and ophthalmology sector must focus on maintaining high standards of operational integrity and customer trust. The following best practices can help optimize payment processes, reduce risks, and foster positive relationships with payment service providers (PSPs).

Classification & transparency

always use the correct MCC associated with optometry and ophthalmology to avoid potential account closures

  • clearly display service offerings, certifications, and patient care policies on your website
  • ensure that billing descriptors accurately reflect the services provided to maintain transparency

Fraud & chargeback reduction

implement 3DS or step-up authentication for high-volume or high-value transactions to minimize fraud

  • use clear and recognizable billing descriptors or notifications to prevent confusion and chargebacks
  • maintain a detailed log of patient interactions, transactions, and service events to support dispute resolutions

Payment acceptance optimization

offer a variety of payment options, including insurance processing, cards, and health savings accounts, to cater to diverse patient needs

  • regularly test different PSP providers to find the most efficient routing for payments, based on geographic or service-specific performance
  • consider using separate merchant identification numbers (MIDs) for different services or locations to better manage requirements and optimize acceptance rates

Operational discipline

monitor key performance indicators (KPIs) such as chargeback rates, authorization rates, and service response times to identify improvement areas

  • conduct regular compliance audits and update policies to ensure adherence to best practices and industry standards
  • designate a team or individual responsible for handling disputes and ensure that they follow strict response timelines

Payouts & liquidity

establish liquidity buffers to ensure you can accommodate rolling reserves or chargebacks without impacting operations

  • automate anti-money laundering (AML) checks for withdrawals to enhance security in financial transactions
  • keep a close eye on payout trends and patient payment behaviors to swiftly address any anomalies in cash flow
