How could CMS updating Medicare rules for outpatient surgery affect ASC?

Possible What happens if… A possibility worth considering, not a forecast.

New cms rules may change revenue and scope for ambulatory surgery centers CMS is restructuring Medicare rules by adding 573 codes to the ASC Covered Procedures List and phasing out the Medicare inpatient-only list over three years. This structural change allows surgeons and patients to decide the site of service for complex spine and joint cases. However, the financial incentives are complex: while cases are migrating to ASCs, the ASC conversion factor ($56.322) remains substantially lower than that of hospital outpatient departments ($91.415), creating a significant reimbursement gap that site-neutral policy is intended to address.

The facts so far

As reported. Each one links to where it comes from.

  • CMS added 573 codes to the ASC Covered Procedures List in its 2026 rule.beckersspine.com
  • The three-year unwind of the inpatient-only list removes 285 mostly musculoskeletal procedures, 266 of which are removed in 2026 alone.beckersspine.com
  • The ASC conversion factor for 2026 is $56.322, compared with $91.415 for hospital outpatient departments.beckersspine.com
  • CMS finalized only a 2.6% ASC payment increase for 2026.beckersspine.com

Why it matters

The ASC industry is undergoing a major structural shift as orthopedic surgery moves out of hospitals. For ASC operators, this migration presents a real opportunity to capture higher-acuity spine and joint cases. However, the current reimbursement structure, where ASCs are reimbursed at a much lower rate than hospitals, means that simply absorbing more volume may not improve the financial arithmetic for the center.

This reimbursement pressure is part of a broader trend toward site-neutral payment, which aims to narrow the disparity by pulling the ceiling down on hospital payments. This policy erodes the economics of hospital-employed physician models, accelerating consolidation, but it does not guarantee improved margins for independent ASCs unless they successfully renegotiate commercial contracts and build payer partnerships.

What we don't know yet

  • Will CMS or payers adjust the ASC conversion factor to better align with the cost of higher-acuity spine and joint cases?
  • How will the rising commercial healthcare costs of up to 8.5% in 2026 influence payer willingness to hold the line on ASC payments?

What would change this answer

CMS increases the ASC conversion factor significantlyThe financial opportunity for ASCs to capture the migrating volume would become much stronger, potentially leading to rapid growth.
Payer contracts shift away from line-item facility fees to total episode valueASC operators could secure better, more stable revenue streams, mitigating the risk associated with facility fee differences.
