Where this comes up
Compliance committees and practice managers operate at this level — written policy, workforce training, sanction policy, monitoring and auditing cadence, response and corrective action. The seven elements of an effective compliance program (OIG) are the scaffolding; this term lives somewhere on that scaffold.
Full definition
What it is in practice
OIG guidance recommends regular internal audits. Common scopes: E/M distribution, modifier-25 utilization, top-billed codes, signature completeness.
How it shows up in your practice
Schedule audits quarterly. Sample size and methodology should be documented. Findings drive corrective action and training.
