Chiropractic Care Plan Reactivation: 5% of Lapsed Patients in 90 Days
Updated May 2026 · 7 min read
This is a worked example of a chiropractic care-plan reactivation campaign, modeled on a typical solo-practitioner office. We use industry-benchmark response rates and PostKnock's actual pricing to show what it looks like to bring back the patients who quietly disappeared mid-care-plan — the single biggest revenue leak in chiropractic practice.
Practice Profile
Our hypothetical practice is Aligned Spine Chiropractic, a solo-DC office focused on auto-injury rehab and corrective care plans. Specifics:
- Team: 1 DC, 1 chiropractic assistant, 1 front desk
- Total patient records: 600 (cumulative over 6 years of practice)
- Lapsed mid-care-plan: 400 patients who started a corrective care plan but stopped showing up before completion
- Average completed care plan value: $1,800 over 12–24 visits
- Average partial-plan reactivation value: $1,000 (assumes patients return for 6–10 remaining visits at $80–$120 per visit)
- Existing recall: Email and text reminders for missed appointments only. No structured reactivation campaign.
The Care-Plan Dropout Problem
Chiropractic differs from dental and optometry in one critical way: a "lapsed patient" usually wasn't done with care. They were prescribed a multi-visit corrective plan, came in 3–6 times, started feeling better, and quietly stopped scheduling. The clinical reality is that they probably stopped before the underlying biomechanical correction was stable, which is why so many of them re-injure within 12–18 months.
This dynamic makes the reactivation message different. You're not selling "come back for a checkup" — you're selling "we never finished what we started, and your symptoms are likely to come back without it." The right copy frames it as caring, not pushy.
Campaign Setup — The 8-Week Reactivation Playbook
A 3-wave Lapsed Patient Reactivation playbook running across 8 weeks, with phone follow-up between each wave. The schedule is tighter than dental's 9–10 weeks because chiropractic patients respond faster when the message lands during a flare-up:
Plan: PostKnock Pro at $99/month (3 months = $297)
Postcard size: 6x9 (room for a spine illustration and a "where you stopped" timeline visual)
Per-card cost: $0.79 (Pro pricing, includes print, address, postage)
Audience: 400 patients lapsed mid-care-plan
Total cards: 400 × 3 waves = 1,200 cards
Postcard spend: 1,200 × $0.79 = $948
Total campaign cost: $948 + $297 = $1,245
Wave-by-Wave Performance
Wave 1 (Week 1) — "[First Name], We Never Finished Your Care Plan"
Personalized greeting. Specific reference to where the patient stopped ("you were on visit 6 of 12"). Free re-evaluation offer. Day 4 follow-up calls by the chiropractic assistant.
Modeled response: 3% from card + 1.5% from call follow-up = 18 patients booked
Wave 4 (Week 4) — "Most Patients Re-Injure Within 12 Months"
Different visual. Educational framing ("research shows patients who stop care mid-plan have a 60% recurrence rate"). Same free re-evaluation offer.
Modeled response: 0.5% of remaining 382 = 2 additional patients
Wave 8 (Week 8) — "Last Reminder — Schedule Your Re-Eval"
Hard deadline. Light copy. Catches the procrastinators.
Modeled response: ~0% additional (catch-up only) = 0 net
Cumulative response: 20 patients reactivated — a 5% rate against the 400-patient list. Solidly inside the house-list benchmark.
The Conversion Call Script That Worked
The phone follow-up after Wave 1 is doing 30%+ of the conversion work. Here's the script the chiropractic assistant uses:
"Hi [First Name], this is Sarah from Aligned Spine. Dr. Carter asked me to reach out personally — we sent you a card last week. I'm looking at your file and I see you were on visit 6 of 12 of your corrective plan back in [month]. Dr. Carter wanted to check in and offer you a complimentary re-evaluation to see how your back has been holding up. Are you free Wednesday at 2pm or would Friday morning work better?"
Three things make this script work: it references the postcard (so it doesn't feel cold), it cites the specific visit number (so it feels personal, not template), and it ends with a binary calendar choice (so the patient has to pick a slot rather than say "I'll call back").
ROI Analysis
- Patients reactivated: 20
- Average partial-plan reactivation value: $1,000
- Year-1 revenue from reactivated patients: 20 × $1,000 = $20,000
- Total campaign cost: $1,245 (postcards + 3 months Pro)
- Net first-year return: $20,000 − $1,245 = $18,755
First-year ROI: $20,000 / $1,245 = 16:1
Cost per reactivated patient: $62. Multi-year LTV if even half re-engage in maintenance care pushes the campaign return well past 30:1 over 24 months.
Lessons Learned (from the Worked Model)
- Reference the specific stop point. Generic recall ("we miss you") underperforms by 2–3x against personalized recall ("you were on visit 6 of 12"). Pull the data from your PMS — it's worth the extra setup time.
- Lead with a re-evaluation, not a discount. Discounts cheapen a clinical service. A complimentary re-eval frames the practice as caring, not desperate.
- Wave 1 does most of the work. In chiropractic, the message lands hardest the first time the patient sees it. Subsequent waves catch the long tail but produce diminishing returns. Don't expect Wave 2/3 to match Wave 1 the way they often do in dental.
- Train the CA on the script. The postcard primes — the call converts. A weak phone follow-up cuts your campaign ROI in half.
