2025/2026 Policy Shifts for California ASCs: Payer Updates, Orthopedic Focus, and Strategic Actions
California Ambulatory Surgical Centers (ASCs) face significant policy changes from major payers in 2025/2026, impacting reimbursement, compliance, and orthopedic service lines. UnitedHealthcare is updating code sets, orthopedic coverage criteria, and implementing payment reductions for off-campus departments. Anthem is revising prior authorization pathways, with Carelon managing some orthopedic codes, and emphasizes accurate coding and documentation. Aetna introduces expanded claim edits, modifier payment changes, new credentialing for physician assistants, and reassigns service codes affecting contract rates. Cigna enforces strict time and distance standards for network adequacy and revises coverage for ankle and knee procedures, as well as anesthesia billing. California-specific mandates require timely transition of care and medical necessity reviews. ASC leaders must proactively monitor payer portals, educate staff on new requirements, optimize documentation, and renegotiate contracts to maximize reimbursement. Staying compliant with state regulations and adapting to evolving payer policies will be critical for operational and financial success in the coming years.
