RO-ILS Subscription Payment Guide
RO-ILS practices are required to pay a non-refundable, annual subscription fee to participate in the program. The subscription rates are based on the number of facilities enrolled within a practice.
The 2026 fees are:
- Base fee (1 facility): $1,000
- Each additional facility (up to 10): +$500 per facility
- Practices with 11-19 facilities: $6,000
- Practices with 20-29 facilities: $8,000
- Practices with 30+ facilities: $10,000
The practice's primary contact (i.e., RO-ILS Liaison) received an email in December 2025 with a link to the 2026 RO-ILS subscription invoice. Payment was due February 2026.
