2020 CERT Supplemental Improper Payment Data
Short Stays Improper Payment Rate at an All-Time High
In mid-November 2020, CMS published a CMS.gov Fact Sheet detailing the estimated improper payment rates for CMS Programs for Fiscal Year (FY) 2020.
Audit findings are used to calculate a Medicare Fee-for-Service (FFS) program improper payment rate. “The CERT program considers any claim that was paid when it should have been denied or paid at another amount (including both overpayments and underpayments) to be an improper payment.”
CMS reminds the reader in the Fact Sheet that improper payment rates are not necessarily indicative of or are measures of fraud. Instead, improper payments are payments that did not meet statutory, regulatory, administrative, or other legally applicable requirements and may be overpayments or underpayments.”
The following tables compares the improper payment rate for FY 2018, FY 2019, and FY 2020.
|Medicare FFS (Part A and Part B) Improper Payment Rate Compare|
|FY 2018||FY 2019||FY 2020|
|Improper Payment Rate||8.12%||7.25%||6.27%|
Fiscal Year 2020 Supplemental Improper Payment Data
On December 21, 2020, CMS released the Supplemental Improper Payment Data Report that delves into the details behind the final Improper Payment Rate and Improper Payments. This report includes a review of claims submitted from July 1, 2018 through June 30, 2019.
“0 or 1 Day” LOS Claims Continued Outlier
Since the Two-Midnight Rule was implemented, the annual data has included a table comparing improper payment rates for Part A hospital claims by Length of stay. At 19.9% for 2020, the Improper Payment Rate for “0 or 1 day” LOS claims is at an all-time high since the CERT began reporting improper payments by LOS.

|Overall Part A (Hospital IPPS)||4.5%||4.4%||4.8%||4.2%||4.0%|

Compliance with Short Stays
Short stay reviews have been under scrutiny for several years. With the consistent increase in the improper payment rate for this patient population it is not surprising that the OIG is once again targeting short stays for review. You can read more about this in a related MMP article.
