Chiropractic-specific AI voice agent workflows for PI (personal injury) case intake, attorney lien docs, DOT physical scheduling, and adjustment package upselling.
Key takeaways
BLUF: A modern chiropractic practice runs on three revenue engines — cash-pay adjustment packages, personal injury (PI) cases on attorney liens, and DOT physical exams at $90-$150 per cert — and each engine requires a completely different intake workflow. Most practices use one underpaid front desk person to handle all three, which is why conversion rates on high-value PI calls routinely fall below 35%. AI voice agents from CallSphere let you run all three workflows simultaneously with identical quality at 7 AM and 9 PM, triple your PI intake capacity without hiring, and convert adjustment inquiries to package buyers at 2.4x the industry baseline. This post covers the PI attorney lien workflow, the DOT Medical Examiner's Certificate scheduling pattern, and the Package Upsell Matrix we've deployed at 140+ chiropractic practices.
The chiropractic vertical is a fascinating case study in why specialty-specific voice agents beat horizontal tools. A healthcare AI built for general primary care has no idea what "lien" means, can't schedule a CDL medical exam, and will happily quote an adjustment price without triggering the package conversion script. Chiropractic demands a specialty agent — and the specialty pays for it.
According to the American Chiropractic Association's 2024 practice economics report, the median chiropractic practice grosses $560,000 annually, with roughly 22% from PI cases and 8% from DOT physicals. A 10% lift in PI conversion alone is worth $12,320 annually to the median practice.
BLUF: Cash-pay wellness care, PI litigation care, and DOT compliance exams each have different callers, different pricing models, different documentation requirements, and different urgency profiles. An AI voice agent trained on all three handles every inbound call with the right script — no routing decisions required from a human.
Let's compare the three engines:
| Engine | Typical Caller | Price Point | Urgency | Documentation |
|---|---|---|---|---|
| Cash-pay wellness | Existing patient or referral | $50-$85/adjustment | Low (1-7 day booking OK) | SOAP note |
| Personal injury | MVA victim within 30 days | $150-$400/visit on lien | High (same-day ideal) | Lien doc, ICD-10, 1500 form |
| DOT physical | CDL driver with expiring cert | $90-$150 flat | High (cert expiring) | Long Form 649-F, MCSA-5876 |
| Workers' comp | Injured worker | Fee schedule | Medium | State WC forms |
| Sports injury | Athlete | Cash or insurance | Medium | Referral coordination |

The agent asks two gating questions ("How did you hear about us?" and "What brings you in today?") and routes to the correct script in under 7 seconds. Cash-pay callers get the Package Upsell script. MVA callers get the PI Intake script with attorney inquiry. DOT callers get the Medical Examiner scheduling script with certificate expiration capture.
BLUF: PI intake is the single highest-value workflow in chiropractic, with cases averaging $4,200-$8,500 in billable care and attorney lien collection rates of 78-94% depending on state and attorney relationships. The intake has 14 discrete steps that must happen in a specific order, and missing any one of them delays the first adjustment or jeopardizes collection.
The CallSphere chiropractic agent runs this 14-step PI intake autonomously:
Each step produces structured data that flows directly into the practice management system. The agent never asks a redundant question, never misses a compliance-critical field, and produces a complete PI chart before the patient walks in.
```typescript // CallSphere Chiropractic PI Agent - lien workflow interface PICase { patient_id: string; dol: Date; // Date of loss accident_type: "auto" | "slip_fall" | "workplace"; police_report: string | null; at_fault_carrier: string; pip_coverage: number; // Personal Injury Protection med_pay_coverage: number; attorney: { represented: boolean; firm: string | null; attorney_name: string | null; lien_pre_auth: boolean; }; symptoms: Symptom[]; prior_care: PriorVisit[]; scheduled_eval: DateTime; imaging_needed: boolean; lead_score: number; // 0-100 from post-call analytics }

A 2024 report from the Insurance Research Council found that chiropractic care is involved in 33% of auto injury claims, with average total chiropractic billing per claim at $2,450 — up 18% from 2019.

BLUF: A chiropractic lien is a legally binding agreement where the chiropractor agrees to provide care without upfront payment in exchange for a claim against the patient's eventual settlement. State-specific lien laws vary wildly — Texas requires filing with the county clerk, California uses a simple letter of protection (LOP), and Florida has statutory lien rights under 713. The voice agent has to know which state applies.
The agent maintains a state-by-state lien rules matrix that governs what it can and cannot promise during the intake call. For represented patients, it captures the attorney's firm, the case manager name, and the LOP or lien document format that firm prefers, then generates the draft lien document for e-signature before the first visit.
| State | Lien Type | Filing Requirement | Typical Collection Rate |
|---|---|---|---|
| California | LOP (letter) | None — contractual | 88% |
| Texas | Statutory | File with county clerk | 82% |
| Florida | Statutory (713.64) | Notice to attorney | 94% |
| New York | Contractual | Notice of lien | 79% |
| Arizona | Statutory | Record with county | 86% |
| Nevada | Medical lien | File within 30 days | 81% |
For unrepresented patients, the agent can offer a warm referral to a pre-vetted PI attorney partner — a huge value-add for the patient and a revenue-sharing opportunity for the practice. Our agents have referred over 8,400 cases to attorney partners across the US in the last 12 months.
BLUF: DOT medical examinations are required for CDL drivers under FMCSA regulations, must be performed by a Medical Examiner listed on the National Registry of Certified Medical Examiners (NRCME), and result in a Medical Examiner's Certificate (MEC) valid for up to 24 months. Drivers whose cert expires are out of compliance immediately, which means the call is high-urgency and the scheduling window is tight.
The CallSphere chiropractic agent handles DOT physicals with a specialized sub-workflow:
```mermaid graph TD A[DOT physical inquiry] --> B[Confirm CDL class] B --> C[Capture current cert expiration] C --> D{Expires within 7 days?} D -->|Yes| E[Urgent scheduling track] D -->|No| F[Standard scheduling] E --> G[Same/next day slot] F --> H[Book within 2 weeks of expiration] G --> I[Send pre-visit requirements SMS] H --> I I --> J[List required meds/conditions] J --> K[Confirm bring eyeglasses/hearing aids] K --> L[Confirm bring CDL, med list] L --> M[Book appointment] M --> N[Send MCSA-5875 prefill link] ```
The agent asks for the driver's current cert expiration date, the CDL class (A, B, or C), and any medical conditions that require documentation (diabetes, cardiovascular, sleep apnea, hearing/vision). Based on conditions disclosed, it sends the correct pre-visit requirement checklist via SMS.
According to FMCSA 2024 data, there are 3.5 million CDL holders in the US, and roughly 1.6 million DOT physicals are performed annually. A chiropractic practice in a trucking corridor can realistically do 15-30 DOT physicals per month at $110-$130 each — $1,650-$3,900/month in cash revenue per examiner.
BLUF: The Package Upsell Matrix is the original CallSphere framework we use to convert single-adjustment inquiries into multi-visit care plan purchases. It cross-indexes symptom complexity, prior chiro experience, and payment sensitivity to recommend one of five pre-priced care packages — and it works because the AI never forgets to present the package, unlike a human front desk.
Here's the matrix:
| Symptom Complexity | First-time Chiro | Returning Patient | Package Recommendation |
|---|---|---|---|
| Acute (1 region, <2 wk) | Single-session eval | 4-pack | Wellness 4-pack at $240 |
| Sub-acute (1-2 region, 2-6 wk) | 6-pack intro at $360 | 12-pack | Recovery 12-pack at $660 |
| Chronic (multi-region, >6 wk) | 12-pack at $660 | 24-pack | Chronic care 24-pack at $1,200 |
| Post-PI transition | Maintenance 8-pack | Maintenance 12-pack | Maintenance at $480-$720 |
| Wellness/preventive | Monthly membership | Monthly membership | $99/mo unlimited |
The agent presents the recommended package based on the caller's answers to three questions: "When did this start?", "Have you seen a chiropractor before?", and "What would feel like a good outcome for you?" — then handles objections with scripted responses around ROI, payment plans, and HSA/FSA eligibility.
Our deployed chiropractic agents convert 41% of cash-pay new-patient calls into package purchases at the point of booking, versus an industry baseline of roughly 17% (ACA Member Practice Survey, 2024). On a practice fielding 100 new-patient calls per month, that's roughly $12,000-$18,000 in additional monthly revenue.
BLUF: A full chiropractic voice agent deployment integrates with the practice management system (most commonly ChiroTouch, Jane, Genesis, or ChiroFusion), an e-signature platform for lien documents, a payment processor for package sales, SMS for intake forms, and a CRM for attorney relationships. CallSphere provides native connectors for the four major chiropractic PMs; custom integrations take 5-7 business days.
The agent uses OpenAI's `gpt-4o-realtime-preview-2025-06-03` model with server VAD and 14 specialized chiropractic tools. Every call produces a post-call analytics record with sentiment -1 to 1, lead score 0-100, detected intent (PI intake, DOT physical, package inquiry, reschedule), and escalation flag. Calls with lead scores above 75 that don't convert on the initial call trigger a 30-minute human callback automatically. Learn more on the features page.
The after-hours escalation agent ladder uses 7 agents with a 120-second Twilio timeout per agent — so if a PI case needs a human (e.g., complex attorney situation), the agent pages the PI coordinator, then the office manager, then the on-call DC, waiting no more than 6 minutes total before falling back to scheduled callback.
BLUF: Chiropractic practices deploying the CallSphere voice agent typically see new-patient call answer rate hit 99%+, PI intake completion reach 94%, DOT physical booking conversion hit 87%, and package purchase conversion improve from 17% baseline to 38-42% within 90 days.
| Metric | Baseline | 30 Days | 90 Days |
|---|---|---|---|
| After-hours answer rate | 43% | 98% | 99% |
| PI intake completion | 61% | 89% | 94% |
| DOT physical booking conversion | 52% | 81% | 87% |
| Package purchase conversion | 17% | 33% | 41% |
| Attorney lien pre-auth rate | 71% | 88% | 93% |
| New patient monthly volume | 100 | 128 | 147 |

Q: Will a PI attorney accept a lien document generated by an AI voice agent? A: Yes — the agent generates the lien document from templates pre-approved by your practice's attorneys. The document is e-signed by the patient and reviewed by the office manager before care begins. The AI never originates legal language; it fills in verified templates.

Q: Can the agent handle Spanish-speaking PI callers? A: Yes. Our chiropractic deployment includes native Spanish support with identical script coverage. PI cases often involve Spanish-speaking claimants; the agent detects language automatically and switches.
Q: How does the agent handle disputes about pre-existing conditions in PI cases? A: The agent captures a detailed prior-injury history as part of the PI intake but does not render clinical opinions about causation. That determination stays with the DC during the initial evaluation. The agent's role is documentation completeness, not clinical judgment.
Q: What about DOT physicals where the driver has a disqualifying condition? A: The agent captures the condition during pre-screening and flags the appointment with a longer time block. The Medical Examiner makes the certification decision. The agent never tells a driver they're disqualified — only that additional documentation or exam time is needed.
Q: How is package pricing customized to our practice? A: During setup, we build your pricing tree into the agent's knowledge base. The agent always quotes exactly your prices, never makes up numbers, and presents objection-handling language you've approved. Changes to pricing are pushed live within 15 minutes.
Q: Does the agent handle Medicare chiropractic coverage rules correctly? A: Yes. Medicare covers only manual manipulation of the spine for subluxation, and the agent knows the coverage rules, the required AT modifier, and the ABN requirement for non-covered services. Medicare patients get accurate out-of-pocket estimates before booking.
Q: What happens when an attorney calls about an existing PI case? A: The agent identifies the attorney caller, pulls the case from the PM system, and either provides the requested records (with consent on file) or schedules a callback with the PI coordinator. All attorney interactions are logged for case management.
Q: How quickly can we go live? A: Two weeks is standard for a full chiropractic deployment, including PM integration, lien templates, DOT workflow, and package pricing setup. Cash-only practices without PI or DOT can go live in 5-7 business days.
BLUF: Every call processed by the CallSphere chiropractic agent produces a structured analytics record with sentiment scored -1 to 1, lead score 0-100, detected intent, and escalation flag. For chiropractic specifically, this analytics layer surfaces business-critical patterns that are invisible in traditional call center data, like which referral sources produce the highest-conversion PI cases and which marketing channels waste ad spend on unqualified callers.
A typical chiropractic deployment generates 500-900 analyzed call records per month. The dashboard surfaces:
Practices use this data to shift marketing spend toward channels that produce actual cash revenue, not just call volume. One three-DC practice shifted $4,200/month in ad spend from a low-converting Facebook channel to a high-converting local GMB posts strategy based on attribution data from the voice agent, producing an estimated $48,000 annual revenue lift at no incremental cost.
The escalation flag triggers human callback for high-value calls that didn't convert. Chiropractic practices see the most value from human callback on PI cases with lead scores above 75 that didn't book on the initial call — roughly 60% of those callbacks convert on the second contact.
BLUF: A three-chiropractor practice in Houston with a heavy PI focus deployed the CallSphere voice agent in October 2025. Within 90 days, they increased monthly PI intakes from 22 to 47, reduced their front desk payroll by 0.8 FTE, and added $94,000 in monthly collected revenue from the combination of PI volume and package conversion.
The practice had been losing weekend PI cases to three competitors that picked up the phone 24/7. The voice agent equalized that disadvantage in the first week and actually created a competitive moat, because the 14-step PI intake produced more complete case documentation than any of the competitors' human-driven processes. Attorneys began preferring this practice because they could send clients there with confidence that the case file would be complete.
Additional outcomes across the 90-day window:
The practice's lead DC noted that the voice agent handles objections on package sales better than any front desk hire he'd had in 18 years of practice — because it never gets tired, never takes an objection personally, and always delivers the approved script accurately.
BLUF: The CallSphere chiropractic agent has native API connectors for ChiroTouch, Jane, Genesis, and ChiroFusion, with full bidirectional data flow — the agent writes new patient records, appointments, insurance info, PI case details, and SOAP notes directly into the PM without manual re-entry.
For ChiroTouch specifically, the connector uses the CT API to create patient records in real time, with PI cases tagged appropriately for billing workflow. Appointments are placed in the correct provider calendar based on appointment type (eval, adjustment, DOT, re-eval). PI lien documents are uploaded to the document manager automatically.
For Jane, the connector uses Jane's webhook infrastructure for bidirectional sync — when the voice agent creates an appointment, it appears in Jane instantly; when Jane clinicians update patient information, the voice agent's context updates within 90 seconds for the next call.
Practices that prefer custom integration can use our REST API with full OpenAPI documentation. Standard custom integrations take 5-7 business days; complex integrations involving multiple legacy systems take up to 3 weeks.
