Billing tips

Bill 93792 only once per training episode, regardless of training duration or number of devices demonstrated
Impact: Prevents denials for duplicate billing; bundling multiple training sessions on same date results in 100% denial of subsequent claims
Verify patient's anticoagulation diagnosis and home monitoring medical necessity are documented before training
Impact: Pre-service verification prevents denials; approximately 15-20% of claims denied due to lack of medical necessity documentation
Document patient or caregiver competency assessment and successful completion of training with return demonstration
Impact: Competency documentation is required for payment; missing competency verification accounts for 25% of audit recoupments
Submit claims within 30 days of service date to avoid timely filing denials
Impact: Late submissions result in 100% denial; Medicare allows up to 1 year but most commercial payers enforce shorter limits
Use modifier 25 when billing same-day E/M service with 93792 to prevent bundling
Impact: Recovers additional $80-$200 for E/M service that would otherwise be denied or bundled
Coordinate with DME suppliers to ensure home INR device is covered and authorized before providing training
Impact: Training without authorized device leads to denials; coordinating coverage prevents wasted training time and $66.63 payment loss

Is CPT 93792 covered by Medicare for home INR monitoring training?

Yes, Medicare covers CPT 93792 when medically necessary for patients who require long-term anticoagulation therapy and are appropriate candidates for home monitoring.

What is the difference between CPT 93792 and other anticoagulation management codes?
