OIG: Hospitals are upcoding severity levels for Medicare patients

Inpatient clinic stays have become much more high priced to the Medicare program. It can be a pattern that began even in advance of the COVID-19 pandemic.

A new report from the Section of Wellbeing and Human Services’ Workplace of the Inspector Common uncovered a achievable motive: Lots of hospitals are increasingly billing for inpatient stays at the best severity level, which is also the most high priced.

In an assessment of Medicare Aspect A statements from 2014 to 2019, the OIG identified that the priciest stays – individuals involving a significant health care complication – rose about 20%, with the value hole in between the best and cheapest Medicare Severity Prognosis Related Team for an sickness like pneumonia settling at $4,175 vs. $8,505. That’s much more than double around the five-year interval.

In the long run, this accounted for practically 50 % of all Medicare shelling out on inpatient clinic stays. The number of stays billed at each of the other severity ranges lessened. 

At the exact same time, the common duration of stay lessened for stays at the best severity level, when the common duration of all stays remained mainly the exact same. 

The problem, in accordance to OIG, is that stays at the best severity level are vulnerable to inappropriate billing methods these as upcoding, the apply of billing at a level bigger than is warranted. 

Especially, practically a 3rd of these stays lasted a notably quick sum of time. Extra than 50 % of the stays that had been billed at the best severity level had only a person analysis qualifying them for payment at that level. Hospitals also diverse substantially in their billing of these stays.

What is actually THE Impact?

Hospitals billed Medicare for 8.7 million inpatient clinic stays in FY 2019. About 40% of them – 3.5 million stays – had been billed at the best severity level. These are typically stays for which the clinic bills for at least a person important complication.

Medicare spent $109.8 billion for inpatient clinic stays in FY 2019. Almost 50 % of that sum, $fifty four.6 billion, was for stays billed at the best severity level. Medicare paid out an common of $fifteen,500 per stay billed at the best severity level.

Medicare payments for stays at the best severity level enhanced steadily in each of the 6 a long time examined. The increases amounted to much more than $ten billion, or 24%. Total, Medicare payments for inpatient clinic stays enhanced by 8% in the course of the exact same time interval. 

The increase in the number of stays billed at the best severity level would ordinarily indicate that beneficiaries had been sicker total. But the decrease in common duration of stay perhaps undermines that plan since it really is inconsistent with sicker beneficiaries. Duration of stay typically has a optimistic connection to severity of stay sicker beneficiaries stay in the clinic extended. 

On prime of that, the common duration of all stay remained mainly the exact same from 2014 to 2019, which suggests that beneficiaries in typical had been not sicker in FY 2019 than they had been in previous a long time. 

Supplied the decrease in the common duration of stay at the best severity level and the sign that beneficiaries in typical had been not sicker, the increase in stays billed at the best severity level possible was pushed by modifications in clinic billing methods alternatively than by modifications in the beneficiary inhabitants, in accordance to the OIG. 

This is significant, since Medicare pays hospitals for each inpatient stay primarily based on the assigned MS-DRG, not on the sum of time the beneficiary spends in the clinic. 

Virtually thirty% of stays billed at the best severity level, almost a million of them, lasted a notably quick sum of time. Especially, they had been much more than 20% shorter than the necessarily mean duration of stay for the assigned MS-DRG. 

Shorter stays are not inherently problematic, but the number of these stays raises queries about the accuracy and appropriateness of the difficulties billed by the clinic. Even though the difficulties billed recommend sicker beneficiaries, the shorter lengths of stay issue to beneficiaries who are significantly less sick. That suggests possible upcoding on the component of hospitals. 

Collectively, Medicare paid out hospitals about $14.5 billion for stays that lasted an primarily quick sum of time. That’s $4.nine billion much more than it would have paid out if these stays had been billed at the subsequent reduced severity level, indicating Medicare perhaps overpaid hospitals by a significant sum if even a fraction of these stays had been billed inappropriately.

THE Larger Trend

OIG recommends a number of steps. The Facilities for Medicare and Medicaid Products and services, it said, must carry out targeted assessments of MS-DRGs and clinic stays that are vulnerable to upcoding and the hospitals that commonly monthly bill for them.

Especially, CMS must goal stays at the best severity level with sure qualities, these as individuals that are notably quick or that have only a person important complication. 

CMS must also look at conducting much more in-depth assessments of the health care record that seem for inconsistencies in diagnoses that connect with into concern the appropriateness of the coding.

In addition to employing the effects of the assessments to recoup overpayments, CMS must use them to educate hospitals about suitable billing, modify coding policies and look at no matter if further more ways must be taken to disincentivize inappropriate billing, the OIG said.
