First-ever ranking of all 50 states by ASC per capita

Marcus Robertson - Updated Wednesday, February 9th, 2022

The number of ASCs is growing across the U.S. as patients and payers demand more outpatient surgery, and the national population is growing overall while state populations continue to shift.

Becker's ASC Review has compiled populational ASC metrics for every state and the District of Columbia based on recently-released 2020 Census data and CMS figures from March 2021.

Maryland continues to lead the pack with 5.54 ASCs per 100,000 people, while nine states have less than one.

Every state, plus the District of Columbia, ranked by populational ASC metrics, in a data set that exists nowhere else:

Note: Blue highlight denotes that a state has no certificate of need law. Green denotes states with CON laws that do not regulate ASCs, according to the National Conference of State Legislatures.
