Understanding S9110 Billing
S9110 is the Texas Medicaid billing code for Remote Patient Monitoring services. Unlike Medicare RPM codes (99453, 99454, 99457, 99458), S9110 uses a unique modifier-based structure that determines reimbursement levels.
S9110 Modifier Breakdown
Each modifier represents a different level of service based on the number of monitoring days and activities performed.
| Modifier | Description | Days | Reimbursement |
|---|---|---|---|
| U1 | Initial Setup | Setup & Training | $50.00 |
| U2 | Minimal Monitoring | 1-5 monitoring days | $40.10 |
| U3 | Basic Monitoring | 6-10 monitoring days | $80.19 |
| U4 | Standard Monitoring | 11-15 monitoring days | $120.29 |
| U7 | Enhanced Monitoring | 16-20 monitoring days | $160.38 |
| U8 | Comprehensive Monitoring | 21-25 monitoring days | $200.48 |
| U9 | Maximum Monitoring | 26-30 monitoring days | $240.57 |
