Referral-to-appointment gap
Referrals arrived via fax, web forms, and EHR messages across different systems with no unified tracking. Cycle times were slow and unpredictable.
Case study
Texas Sleep Medicine deployed Linear Health to consolidate fragmented operations, take a 37% missed-call rate to near zero, reactivate dormant patients, and automate referral-to-revenue workflows end to end.
The challenge
Texas Sleep Medicine is a specialty practice focused on diagnosing and treating sleep disorders, a field where patient volume depends heavily on inbound referrals from primary care and where operational complexity spans clinical scheduling, DME coordination, insurance workflows, and ongoing patient follow-up.
The practice was running on a patchwork of 5+ disconnected systems with a 37% missed call rate, meaning more than one in three patients calling never reached a live person.
Referrals arrived via fax, web forms, and EHR messages across different systems with no unified tracking. Cycle times were slow and unpredictable.
Patients who hadn't returned for CPAP compliance checks, retitration studies, or annual evaluations represented untapped recoverable revenue with no systematic re-engagement.
CPAP machines, masks, supplies, and compliance tracking created a parallel workflow intersecting with scheduling, verification, and billing.
More than one in three patients calling the practice never reached a live person. The phone infrastructure had no call queue and no overflow handling.
The solution
Replaced five disconnected tools with a single system integrated with athenahealth.
All referral channels (fax, web forms, EHR messages, and phone) now feed into a single automated pipeline. Linear's AI extracts patient demographics, insurance information, referring provider details, and clinical indications. The system creates or matches patient records in athenahealth, attaches referral documents, and verifies insurance eligibility in real time.
Patients are contacted automatically via SMS, email, and voice AI. The system handles scheduling conversations end to end, matching patients to available appointment slots based on provider availability, location, and insurance, booking directly into athenahealth.
Linear Health identifies dormant patients directly from athenahealth records: patients overdue for follow-up visits, CPAP compliance checks, or annual evaluations. Hundreds of dormant patients have been re-engaged and rescheduled since deployment.
The most transformative change: AI-powered voice handles inbound calls across new patient scheduling, CPAP/DME questions, rescheduling, billing inquiries, and after-hours coverage. Every call is answered regardless of time.
DME workflows (CPAP orders, supply reorders, compliance tracking, and insurance authorization) are managed through the same platform. Charge entry, eligibility verification, and billing follow-up tasks are automated.
The results
Operational consolidation and patient reactivation across the practice.
| Metric | Before | After |
|---|---|---|
| Missed call rate | 37% | ~0% (every call answered) |
| Operational tools | 5+ disconnected systems | 1 unified platform |
| Patient reactivation | Ad hoc / not systematic | Hundreds re-engaged |
| DME coordination | Manual spreadsheets | Automated within platform |
| Billing workflows | Manual | Automated with voice AI |
| Call handling | Call center + voicemail | AI with warm human transfer |
Testimonials
Linear Health completely transformed how we operate. They replaced five disconnected tools we were using to manage referrals, scheduling, and patient outreach. Now our entire workflow runs through one platform: referral intake, appointment booking, patient reactivation, front desk voice AI, DME coordination, and billing. It's transformed how we operate.

Before Linear Health, I was managing five different systems just to get a patient from referral to appointment. Now I have one screen. Our team went from chasing spreadsheets and voicemails to actually coordinating care. The difference is night and day.
