The Centers for Medicare & Medicaid Services (CMS) has published its final determinations for the HCPCS Level II Q1 2026 coding cycle, providing important updates for providers, suppliers, and billing teams.
This release includes new codes, revisions, and other coding decisions that may directly impact claims submission and reimbursement. Each decision is supported by detailed documentation outlining the coding issue, a summary of the original request, and CMS’ final determination—giving providers helpful context behind each update.
For organizations, this is a key opportunity to review coding changes and ensure systems, workflows, and billing practices are aligned with the latest requirements.
