Block utilization at 2-OR ASCs fell to 59% in 2025 from 71% in 2024, while centers with 10 to 14 ORs rose to 59% from 50%, according to HST Pathways’ 2026 State of the ASC Industry Report.
The report draws on data from 682 surgery centers in 45 states.
Here are five things to know:
1. Block utilization at 2-OR centers was 69% in 2023, 71% in 2024 and 59% in 2025.
2. Larger centers improved. Centers with 10 to 14 ORs went from 50% in both 2023 and 2024 to 59% in 2025. Centers with seven to nine ORs went from 52% to 51% to 58%.
3. Centers with five or six ORs had the highest block utilization in 2025, at 61%. Centers with three or four ORs dropped each year, from 67% to 62% to 57%. Single-OR centers were at 51%.
4. Smaller centers still lead in other areas. In 2025, 2-OR centers had the lowest days to bill and the highest monthly case volume, the report said. Centers with 10 to 14 ORs had a 73% net collection rate, which the report describes as an operational inflection point as complexity grows.
5. Centers with three or four ORs were the largest group in the sample, at 187. There were 58 centers with two ORs and 49 with 10 to 14 ORs. Centers with five or six ORs accounted for the most visits, at nearly 1.4 million.
