Payer-Side

Turnaround Time (TAT)

The time elapsed between a prior authorization request submission and a payer's final determination, now subject to regulatory maximums.

What it means

TAT is now a compliance metric as much as a performance one, given CMS-0057-F's mandated 72-hour and 7-day maximums. Payers and vendors alike need to track this closely, since falling outside these windows carries regulatory exposure, not just customer dissatisfaction.
