Permanent Impairment and the 18% Threshold – What It Means and What to Expect in the Coming Years

Permanent impairment has been in the news in recent months. With the Law Court’s decision in Bailey v. City of Lewiston (2017 ME 160), it has held that an established permanent impairment rating is not subject to revision, even in the face of changed medical circumstances. In Somers v. S.D. Warren Co. (Maine Workers’ Comp Board [WCB] App. Div. No. 17-38 [November 13, 2017]), the Appellate Division held that the WCB may not revise a previously established permanency rating in an upward manner.

With the recent focus on permanent impairment, it is worth addressing the current permanency threshold and what it means for ongoing benefits.

Permanent impairment is “any anatomic or functional abnormality or loss existing after the date of maximum medical improvement that results from the injury” (39-A M.R.S.A. § 102). Maximum medical improvement is defined as, “the date after which further recovery and further restoration of function can no longer be reasonably anticipated, based upon reasonable medical probability.”

For injuries on or after January 1, 1993, permanent impairment no longer means additional benefits for an injured worker, but it plays a significant role in determining how long partial incapacity benefits can be received (the level of permanent impairment does not come into play for total incapacity benefits, which must be paid for the duration of disability).

If permanent impairment is below the applicable threshold, injured workers may not receive partial benefits beyond 520 weeks. However, if permanent impairment exceeds the threshold, benefits may continue for the duration of disability.

The permanent impairment threshold for injuries is as follows:

• Injuries from January 1, 1993, to December 31, 1997, the threshold is 15%
• Injuries from January 1, 1991, to December 31, 2001, the threshold is 11.8%
• Injuries from January 1, 2002, to December 31, 2003, the threshold is 13.2%
• Injuries from January 1, 2004, to December 31, 2005, the threshold is 13.4%
• Injuries from January 1, 2006, to December 31, 2012, the threshold is 12%

For injuries on or after January 1, 2013, if, at 520 weeks, the partially incapacitated employee is working, earning 65% or less of his average weekly wage, and permanent impairment attributable to the injury is “in excess of 18%,” partial incapacity benefits may be required beyond 520 weeks so long as the employee continues to work and earn less than his average weekly wage. Regardless of the extent of permanent impairment or level of earnings, partial incapacity benefits may be extended beyond 520 weeks if the employee proves “extreme financial hardship due to inability to return to gainful employment.”

We are just over five years into a new permanent impairment threshold. In less than five years, those employees with injuries in early 2013 will be involved in litigation over cessation of benefits. The changes for injuries on or after January 1, 1993, will not begin to have a major impact until approximately 2022 or 2023, when the first group of employees with 2013 injuries will be involved in litigation over permanent impairment and cessation of benefits. Still, the threshold has an immediate impact when valuing cases for settlement purposes and planning for the future. Expect to see increased instances where individuals claim financial hardship, or continuing cases where employees try to allege they have 18% or more whole person permanent impairment. With this increased permanency threshold, generally only more serious injuries and/or injuries involving permanency from a psychological sequela will exceed the threshold.

Appellate Division Revisits Res Judicata and Permanent Impairment in the Wake of Bailey v. City Of Lewiston

In Somers v. S.D. Warren Co., WCB App. Div. No. 17-38 (November 13, 2017), the Employee appealed a decision granting S.D. Warren’s Petition for Review and request to discontinue payments due to the expiration of the 520-week durational limit on incapacity benefits.

In a 2008 decree, the administrative law judge (ALJ) found the Employee’s knee condition resulted in 7% whole-body permanent impairment. The ALJ specifically declined to award any permanent impairment for the Employee’s adjustment disorder, a psychological sequela of the knee injury because, according to the § 312 Independent Medical Examiner, she did not sustain any permanent impairment due to that condition.

Litigation was commenced when S.D. Warren filed a Petition for Review seeking to terminate benefits based on the 520-week durational limit (under § 213 of the Maine Workers' Compensation Act, compensation for partial incapacity is payable for a maximum of 520 weeks, except in cases where an employee’s whole-person permanent impairment exceeds a given percentage [set by the Board]). On the other hand, the Employee argued that a “change in circumstances” since the prior decree—a worsening in her right knee and psychological conditions—justified reevaluation of her permanent impairment rating.

The ALJ found the Employee failed to establish a medical change in circumstances sufficient to overcome the res judicata effect of the 2008 decree. Thus, the ALJ found the impairment rating remained at 7%. The Employee filed a Motion for Further Findings of Fact and Conclusions of Law. In response, the ALJ did not alter the outcome, but issued an amended decree finding that any change in the Employee’s psychological condition was a change in degree, rather than kind.

On appeal, the Employee argued that the ALJ erred in finding that she failed to prove a change in circumstances necessary to overcome the res judicata effect of a 2008 decision establishing permanent impairment (valid decisions of the Workers’ Compensation Board are subject to the rules of res judicata and are no longer subject to collateral attack after they become final. This point becomes particularly important, as explained below).

Before a decision was issued, the Law Court issued its decision in Bailey v. City of Lewiston, 2017 ME 160. In Bailey, the Law Court has held that permanent impairment and maximum medical improvement are not subject to reconsideration, even in the face of changed medical circumstances. The Appellate Division offered its interpretation of a seemingly unclear point in the wake of Bailey. Namely, exactly what happens when an employee seeks to increase permanent impairment after a decree establishing permanency. To be clear, Bailey addressed whether a downward revision of permanent impairment was possible. The Employee argued that the Bailey decision should be limited in its application to that set of facts. The Appellate Division disagreed:

"We disagree with this contention. The issue in Bailey, as framed by the Court, was whether the Workers’ Compensation Act allows the Board to revise a previously established impairment rating. It answered that question in the negative without distinguishing between upward and downward revisions. Therefore, pursuant to Bailey, the ALJ did not err when declining to revise the 7% impairment rating assigned to [the Employee’s] knee in the 2008 decree."

The Employee also argued that the Board should have increased her whole body impairment rating to account for added impairment related to her psychological sequela. However, in 2008 the ALJ had essentially found 0% psychological impairment and that figure cannot now be adjusted upward based on changed circumstances. 

The ALJ granted S.D. Warren’s Petition for Review and allowed it to cease paying partial incapacity benefits. 

Time will tell whether the case is appealed to the Law Court.
