Home / Blog / ArticleFQHC PPS Rate Setting and Cost Reports: How Your AIR Gets Built (and Where It Leaks)
The Prospective Payment System rate that drives every FQHC encounter payment is built from your cost report — and most clinics leave $150K–$500K per year on the table.

The short answer — Every FQHC gets paid a single all-inclusive rate (AIR) per qualifying visit — set by your MAC based on your UDS-aligned cost report. That rate compounds. A $10 rate error today costs roughly $10 times every visit you see for the next several years until the next rebasing cycle. CMS last rebased FQHCs in 2014; pending legislation and HRSA guidance in 2025 have renewed attention to rate accuracy. The leakage points are predictable: misclassified costs, missing scope-of-service change requests, under-documented new service lines, and incorrect provider time studies. This post walks through the AIR calculation from scratch, explains how scope-of-service changes trigger rate adjustments outside the rebasing cycle, identifies the seven highest-impact cost report line errors, and shows the revenue math on fixing them. If your FQHC sees 15,000 visits per year and your AIR is suppressed by $12, you are leaving $180,000 per year on the table — every year until someone fixes the cost report.
