D-01 — PATIENT ACQUISITION COST · EYE CARE GROUPS

Cost per new patient is climbing — eye care

Cost per exam is climbing — and the exam is worth less than it was

DIFFERENTIAL — LIKELY CAUSES, MOST LIKELY FIRST

1. 01

   Paid spend is buying exams the recall file should have delivered for nothing

   When recall is weak, media backfills it. The practice pays acquisition prices for a patient it already owned, and the cost-per-exam line rises even though nothing about the market changed.

   Median marketing spend of $4.11 per complete exam, average $5.65 — and this is spend ÷ TOTAL exams, blended across new and returning patients, so recall exams are already in the denominator. Meanwhile the median practice runs 43 complete exams per 100 active patients, a 28-month recall interval. Distribution: 5th percentile $0.25, 25th $2.05, median $4.11, 75th $7.82, 85th $10.91, 95th $21.92 — a 5.3× spread from median to 95th.

   MBA "Key Metrics," p.45 and p.11 — n>1,900 US private optometric practices. This is the nearest thing to a published acquisition cost in optometry and one of only three verticals in our harvest that has one at all. 2015 edition, data largely 2010–2012: the dollar level is dated, the distribution shape and the per-exam denominator are the durable findings. Do NOT read $4.11 as cost per new patient — it is spend ÷ all complete exams.

   NOT THIS IF — Your recall ratio is already above 50 exams per 100 active patients. Then paid media is buying genuinely incremental exams and the cost question is a real efficiency question.

2. 02

   Payer mix shifted — the exam is worth less, so cost per exam rose without spend changing

   Managed vision care pays roughly half the private-pay exam fee. As the managed-care share of exams rises, the collected fee falls, and a constant marketing spend becomes a larger share of a smaller number. Nothing about acquisition got more expensive; the unit got cheaper.

   Average collected exam fee for insured patients: $66. Weighted average direct-pay exam fee: $134 (median $127) — managed vision care pays about 49% of the private-pay fee. A median of 65% of exams carried a managed-care discount, and the share of exams discounted moved from 47% (2001) to 61% (2011) at the national level. In owner-OD billings, self-directed vision plans (30%) have nearly caught direct patient payment (31%).

   MBA "Key Metrics," pp.17, 19 (n>1,900, 2010 fee data; AOA figures for 2001 and 2011 quoted therein). Payer mix: AOA Research & Information Center, 2022 Survey of Optometric Practice: Income from Optometry, Figure 5 (2021 data) — the AOA discloses its own self-selection limitation in writing.

   NOT THIS IF — Your managed-care share of exams has been flat for three years and your collected exam fee has held. Then the unit did not get cheaper and the cost increase is on the acquisition side.

3. 03

   Cost per exam is being measured against the clinical fee instead of the exam's real value

   Divide marketing spend by exam-fee collections and every acquisition looks expensive. Divide it by what the exam actually produces once optical and contact lens revenue are attached, and the same spend is a rounding error. Practices routinely make budget decisions on the wrong three-times-too-small denominator.

   Collected revenue per complete exam: $90 average, $79 median. Gross revenue per complete exam: $306 median. The exam itself is about 29% of what the exam is worth. Against $306, the median marketing spend of $4.11 is 1.3% of revenue per exam — and the primary states that in nearly all practices marketing spending per patient is less than 5% of revenue collected per patient.

   MBA "Key Metrics," pp.5–6, 19, 45 (n>1,900). 2015 edition — levels dated, ratio structural.

   NOT THIS IF — You already compute cost per exam against gross revenue per exam and report the two side by side.

4. 04

   A capture leak is making every acquired exam worth less than the last one

   Cost per exam is only half of a ratio. If capture rate falls, the value side of the ratio falls with it and the practice experiences it as rising cost. Buying more exams into a leaking dispensary raises spend and lowers return simultaneously.

   Median 61 eyewear Rxes per 100 complete exams; top decile 109, bottom decile 30 — a 3.6× spread, and the ratio does not vary significantly by practice size. Modern transaction-derived corroboration: 60.1% optical capture rate across 1,000 US practices and over 7 million recorded exams and eyewear purchases in 2024 (denominator: eyewear purchases ÷ recorded exams).

   MBA "Key Metrics," p.21 (n>1,900) and GPN Technologies analysis of its own database, published at GPN VISIONS (2024). Note the two figures use DIFFERENT denominators — the MBA ratio counts eyewear Rxes including lens-only jobs and can exceed 100; GPN counts purchasing patients ÷ examined patients. They are not the same measurement and should never be blended.

   NOT THIS IF — Your eyewear Rxes per 100 complete exams is above 76 (70th–79th percentile). Capture is not where the value is leaking.

5. 05

   The budget is too small for cost-per-exam to be the operative question

   Below a certain absolute spend, efficiency work has no material to work on. A practice spending under $500 a month has no channel mix to optimise, no statistical basis to attribute, and no headroom for the fixed cost of measurement. The honest answer is that cost per exam is not the constraint.

   60.35% of optometrists reported spending less than $500 per month on marketing, and 5.75% did not know their marketing budget at all — while 48.3% named growing their business in their current location as their top goal. The trade press covering the study called it "the paradox facing independents."

   IDOC and Eyes On Eyecare, "The 2025 Optometrist Report," fielded September 2025, n=543 US and Canadian optometrists — quoted verbatim in Vision Monday. Includes Canadian respondents.

   NOT THIS IF — You are spending above roughly $10.91 per complete exam (85th percentile) or into five figures monthly. Then exam acquisition at that scale is a real question with real money behind it.

HOW TO TELL THEM APART

How to tell these apart in your own numbers

Each of these is a measurement you can run yourself, without us.

WHAT RESOLVES EACH

What resolves this, and how you will know it resolved

Paid spend is buying exams the recall file should have delivered for nothing	Rx 03 · patient conversion →	Recall and pre-appointing displace paid exams at a fraction of the cost. This is the single highest-return move available in this vertical and it is not a media move. What does not work: scaling spend into a 28-month recall interval — you are renting patients you already owned.
Payer mix shifted — the exam is worth less, so cost per exam rose without spend changing	Rx 04 · marketing attribution →	Report the managed-care share of exams and the two collected fees separately, monthly, so a mix shift is visible as a mix shift rather than as 'marketing got more expensive.' What does not work: outspending a $66-versus-$134 fee gap with media. No budget closes a structural payer-mix haircut; only mix, medical optometry share and optical attach do.
Cost per exam is being measured against the clinical fee instead of the exam's real value	Rx 04 · marketing attribution →	One monthly readout with collected revenue per exam, gross revenue per exam, and marketing spend per exam on the same page. Three numbers, one line each.
A capture leak is making every acquired exam worth less than the last one	Rx 03 · patient conversion →	The handoff from the exam room to the dispensary is an intake process, and it is measurable. Fixing it raises the value side of the cost-per-exam ratio without touching spend — which is why it should be fixed before any acquisition work starts.
The budget is too small for cost-per-exam to be the operative question	Rx 01 · patient acquisition →	Stated plainly: we would not take an acquisition engagement against a sub-$500/month budget. A majority of the profession sits there, and the honest advice is to spend nothing more and work recall, capacity and capture first. Acquisition becomes the right conversation after those three are measured and moving.

HOW THIS DIFFERS BY SCALE

How this differs by scale

Single site	One number, computed by hand in an afternoon: annual marketing spend ÷ complete exams. Most single-site practices discover they are at or under the $4.11 median and that the real cost was never media — it was the 57 patients per 100 who did not come in.
Group	Cost per exam only means something per site, because payer mix and recall discipline differ per site and both move the denominator. A group-blended cost per exam hides the one office that is genuinely inefficient behind three that are not, which is why cost per exam, per office is the line we report from the first month.
Platform	At platform scale the question becomes whether marketing spend per exam is a managed line at all, or the sum of whatever each practice was doing before acquisition. Standardising the measurement — spend ÷ complete exams, per site, monthly, against gross revenue per exam — is usually worth more than the first year of spend optimisation on top of it.

• Exam volume is flat — and the unserved demand is already in the recall file
• The exams happen. The purchase happens somewhere else.
• Same brand, same frame boards — and three times the revenue per exam between offices
• The earnings are real. The system that produces them is not visible.
