Credit Card Surcharging in Healthcare

Context: SGA turned on 3% credit card surcharging at 17 Periodontics offices (March–May 2025). Early dashboard data shows patient case acceptance down ~2.7pp (not statistically significant); dollar-weighted acceptance down ~4.6pp — suggesting disproportionate impact on high-ticket plans. This brief summarizes 2022–2026 literature on surcharging, behavioral-economics framing, state legality, and specialty-dentistry analogs to inform interpretation.

Key Findings

Patient retention risk is large and well-documented. Market research consistently reports that 55%–75% of customers say they would not return to a business that surcharged them; some studies cite up to 95%. Stated intent overstates actual churn, but the directional signal is unambiguous (Dental Managers Association; Decisions in Dentistry 2025; Clearwave 2024).

Economics often net negative for the practice. Dental offices typically run a 2.0–2.2% effective processing rate. A 3–4% surcharge plus a $40+ monthly program fee largely enriches the processor, not the practice. With LTV ≈ $4,500/patient and CAC of $150–$300, losing even a few patients per location wipes out fee savings (Decisions in Dentistry Nov 2025; ADA News).

Surcharges amplify behavior change more than equivalent discounts. UCLA Anderson / Lieberman, Duke & Amir (2019, Organizational Behavior and Human Decision Processes) found that a surcharge frame triggers guilt, embarrassment, and greater behavior shift than a mathematically identical discount — a feature when nudging behavior, a bug when the surcharge is on elective, high-ticket care people are already ambivalent about.

Pain-of-paying is magnified at high price points. Behavioral-economics literature (Zellermayer; Prelec & Loewenstein; TRC Market Research 2023) shows surcharges separated from base price make totals feel higher, increase payment salience, and disproportionately suppress purchase intent at high absolute dollar values — consistent with SGA's $5K–$30K perio plans where a $150–$900 surcharge line is newly visible.

Healthcare adoption is rising but patient friction is too. Clearwave (2024) reports surcharging now appears on ~25% of healthcare transactions, roughly 2x YoY. Clearwave's 2026 specialty-payment trends brief explicitly warns that specialty practices (perio, ortho, oral surgery, GI) see larger acceptance drag because a higher share of patients are on financed/elective care with thin affordability margins.

Dollar-weighted > patient-count delta is the expected signature. No public dataset quantifies the exact pp spread, but Overjet's 2024 case-acceptance brief notes large plans ($3K+) already run at 30–50% acceptance vs. ~70% for small plans. Any friction (financial or communicative) amplifies on large plans. SGA's ~1.7x dollar-to-patient drag ratio is directionally consistent with sticker-shock theory.

Legal / Regulatory Notes — SGA's 17 Offices

State	Offices	Status	Action
California Monterey, Walnut Creek, Danville	3	Banned Effectively banned — SB 478 (eff. 7/1/2024) requires advertised/quoted price to include all mandatory fees. Surcharge line added at checkout violates the CLRA.	Audit immediately; litigation & AG enforcement exposure.
Texas El Paso, Rockwall, Paris, Arlington	~7	Gray zone Statute bans surcharging; 5th Cir. (Rowell, 2018) held it unconstitutional as applied, but TX AG's 2019 opinion states the law remains enforceable. Cash-discount framing is safer.	Consult counsel; consider reframe.
New Mexico Las Cruces	1	Permitted Standard card-network disclosure rules apply.	OK with disclosure.
Utah Kaysville, Ogden	2	Permitted No state restriction beyond network rules.	OK.
Ohio Columbus, Newark, Dublin	3	Permitted No state restriction.	OK.

Network caps: Visa 3% max; Mastercard 4%; debit cards may not be surcharged under any circumstances. Virtual credit cards from dental insurers (VCCs) decline when surcharged — practices must either reduce the service fee or refuse the VCC.

Alternatives — Other Ways to Recover 3%

Cash/ACH/check discount — legal in all 50 states, including CA and TX. Economically equivalent to a surcharge but framed as a reward; avoids SB 478 and TX statute exposure.
Modest fee schedule increase (1.5–2%) baked into list price — preserves transparency, sidesteps checkout friction, and is what ADA News and Dental Managers Assoc. recommend as the "quietly preferred" path.
Renegotiate merchant processor / switch to interchange-plus — DSOs of SGA's scale can routinely get effective rates near 1.7–1.9%, recovering 30–50bps without touching the patient.
Expand financing funnel — CareCredit, Sunbit, Cherry, Proceed Finance. For $5K+ perio plans, moving the patient to a financing product shifts the processing cost off the practice entirely while improving case acceptance.
ACH/echeck incentive — explicit $25–$100 rebate for ACH on $5K+ plans; captures fee savings and rewards the behavior.
Minimum surcharge threshold (surcharge only ≥ $X) — reduces friction on diagnostic visits; doesn't solve the sticker-shock problem on the high-ticket plans that matter most.

Application to SGA — How Julia Should Read the Numbers

The 4.6pp dollar-weighted drop is more credible than the 2.7pp patient drop, and aligns with theory. Pain-of-paying scales with absolute fee. A 3% surcharge on a $20,000 perio plan is a $600 line item — visible, unfamiliar, negotiable-feeling. The literature predicts exactly this: modest patient-count effect, larger dollar-weighted effect, concentrated in large plans.
Expect the gap to widen, not close. Word-of-mouth and review-site effects lag by 3–6 months. Early numbers typically understate long-term drag.
California offices are a legal liability, not just a revenue question. SB 478 enforcement is live. Recommend pulling surcharges in Monterey / Walnut Creek / Danville before Q3 and reframing as cash-discount or bundling into fee schedule.
Texas offices are in a defensible but not clean position. Cash-discount reframe is the low-risk path.
The "savings" are likely illusory at the network level. Net of attrition (even modest — 1 lost $15K plan per office/quarter ≈ $1M/yr across 17 offices) plus program fees plus VCC complications plus CA/TX legal exposure, surcharging very likely destroys value. The dashboard's 4.6pp dollar drop on perio caseload almost certainly exceeds the 3% recovery in dollar terms.
Recommended reframe for the board: Run a 90-day A/B where 8–9 offices sunset the surcharge and adopt cash-discount + ACH incentive + financing-first workflow. If dollar-weighted acceptance recovers by >2pp, the experiment pays for itself at scale.
