What is Preauthorization vs. Predetermination?
Definition
Preauthorization vs. Predetermination refers to two different payer processes used before care is delivered. Preauthorization (prior authorization) is mandatory approval confirming medical necessity for specific services; failure to secure it often results in a 100% denial even if the patient is eligible (e.g., MRI or sleep study). Predetermination, common in dental, is a voluntary review that estimates coverage and patient cost (e.g., a predetermination for a crown returns an allowed amount of $1,200 with 50% coinsurance), but it is not a guarantee of payment.
Why It Matters
Missing prior authorization can drive 10–20% of preventable write-offs and reschedules, disrupting multi-location schedules and cash flow. For DSOs, timely predeterminations increase case acceptance and production; moving approval turnaround from 5–7 days to 24–48 hours can add hundreds of booked procedures per month. In a $200M service line, cutting auth-related denials by just 1 percentage point protects $2M annually.
How Ventus AI Helps
Ventus AI agents submit and track prior authorizations and dental predeterminations directly in payer portals, attaching clinical notes, radiographs, and required forms via browser-native automation—no APIs or payer integrations needed. They monitor statuses 24/7, push updates into the PMS/EHR, and prioritize cases by appointment date and timely-filing limits. The same approach that enabled Smilist to status 3,000+ claims weekly scales authorization workloads across hundreds of providers without adding headcount.
