Source article Atlas Managed Care on LinkedIn: California's Q3 OMFS update quietly reset every workers' comp bill dated after July 1.

California updated its Official Medical Fee Schedule mid-year on July 1, 2026, and every workers' comp bill dated after that runs against a different rulebook.

The Q3 OMFS order adopts the Medicare July 1, 2026 quarterly relative value file, updated procedure-to-procedure edits, and updated medically unlikely edits. Small changes on paper. Big changes on a P&L when they hit thousands of physician and non-physician service lines per month.

Bill review programs that reprice against last quarter's schedule quietly leak money on every affected line. Programs that catch the update on day one recover the difference on the same claim they would otherwise close and forget.

Atlas bill review updates fee schedule logic on the effective date, not the following month. Every reviewer works from current OMFS on current CPT edits, with clinical review layered on top for outliers.

If your bill review vendor cannot show you which fee schedule version was applied to a given claim date, what is the audit trail actually worth?
