"As for the difference between state and HHS Protect data, an HHS official contends state numbers “are always going to be lower” by up to 20%. That’s because hospitals could lose Medicare funding if they do not report to HHS, the official says, but face no penalty for failing to report to the state. So rather than expect identical numbers, HHS looks for state and federal data to reflect the same trajectory—which they do in all cases for COVID-19 inpatient data, according to another confidential CDC analysis of HHS Protect, covering all 50 states. "Yet the same analysis found 27 states recently alternated between showing more or fewer COVID-19 inpatients than HHS Protect—not always just fewer, as HHS says should be the case. Thirty states also showed differences between state and HHS Protect figures that were frequently well above the 20% threshold cited by HHS, and HHS Protect data fluctuated erratically in 21 states (see chart, below)."
