"Patient acquisition" gets treated as one problem, but a $120 urgent-care visit and a $20,000 IVF journey have nothing in common except a waiting room. The practices that grow profitably price acquisition by specialty, measure it at the attended appointment, and fix the funnel before buying more traffic. Here's the framework.
PAC: the number, defined properly
Patient acquisition cost = marketing spend ÷ new patients who attended — not inquiries, not bookings. Healthcare no-show rates make everything upstream of the attended visit a vanity metric, and ad platforms optimize toward whatever you feed them: feed them form fills and they find form-fillers (the same lesson from every vertical we run).
Directional paid-channel ranges by specialty:
| Specialty tier | Typical PAC | What justifies it |
|---|---|---|
| General / urgent care | $80-300 | Volume + recall lifetime value |
| Dental, derm, physio, vision | $150-500 | Procedure revenue + recall (dental deep-dive) |
| IVF, bariatrics, cosmetic, ortho surgical | $300-1,500+ | $5K-30K+ case values |
The absolute number matters less than the ratio: PAC against 12-month (or case) patient value, per specialty.
The strategy stack
1. Fix the funnel first. Mystery-call your own front desk. Practices routinely miss 20-40% of new-patient calls — meaning PAC could drop by a third with zero ad changes. Online booking, call answer rates, and same-week availability move acquisition more than creative ever will.
2. Procedure-level campaigns. Generic "doctor near me" budgets subsidize your lowest-value visits. High-LTV service lines get their own campaigns, landing pages, and PAC targets — the architecture we detail in the healthcare playbook.
3. Reactivation. Lapsed patients are acquisition you already paid for. Recall campaigns through your PMS/CRM list are the cheapest "new" patients in every practice, every time.
4. Reviews + map pack. For local care, the Google Business Profile decides the shortlist before your site loads. Review velocity is the lever.
5. LSAs where your category qualifies — pay-per-lead with a verified badge is live for a growing set of healthcare categories by metro.
6. Referrals, formalized. Both patient-to-patient and provider-to-provider (for specialty practices, referring-physician relationships are a channel with its own CRM discipline — the same logic as HCP marketing).
The compliance layer that shapes everything
US practices operate under HIPAA in the funnel: no condition-based remarketing audiences, careful handling of form data and call recordings, BAA-covered vendors, and conversion events that carry appointment status — never diagnosis. (Running outside the US? India's DPDP Act imposes a similar discipline — our India healthcare playbook covers it.) Built correctly from the start, compliant tracking measures everything that matters; retrofitted, it's a rebuild.
Set the budget backwards from capacity
Skip the "percent of revenue" debate: count open appointment slots per week, multiply by your specialty's target PAC, and that's the budget that fills the schedule. Scale it only when capacity scales — a full practice buying more leads is buying no-shows.
