310 P.3d 674
Or. Ct. App.2013Background
- Claimant slipped at work (2008) injuring his right foot; employer accepted a nondisabling foot strain claim.
- In 2009 claimant sought coverage for an undiagnosed navicular fracture and avascular necrosis (AVN) that predated the work injury; employer issued a “combined condition denial.”
- Claimant had preexisting degenerative arthritis in the injured foot; arthritis qualifies as a statutory “preexisting condition.”
- ALJ found the work injury was at least a material cause of disability/need for treatment and that a combined condition existed (work injury + preexisting arthritis); ALJ ruled employer failed to prove the work injury was no longer the major contributing cause.
- The Workers’ Compensation Board adopted the ALJ’s facts but characterized the OCI as the post-injury manifestations of AVN and fracture, and likewise found employer did not meet its burden to show those OCIs ceased to be the major contributing cause.
- Employer appealed, arguing the board should have compared the OCI’s contribution against all other contributing conditions (arthritis plus AVN and fracture), not only the statutory preexisting condition.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Scope of a "combined condition" under ORS 656.005(7)(a)(B) | Combined condition = OCI + statutory preexisting condition only | Combined condition = OCI + PEC + any other contributing conditions | A combined condition consists only of an otherwise compensable injury (OCI) plus statutory preexisting condition (PEC). |
| What factors count in the "major contributing cause" analysis (ORS 656.266(2)(a)) | Compare OCI only to PEC (board/claimant) | Compare OCI to PEC plus all other contributing conditions (employer) | Major-cause comparison is limited to the contributions of the OCI versus the PEC; other conditions outside those components do not enter the analysis. |
| Applicability of Bowen (occupational disease precedent) to combined-condition industrial-injury claims | N/A (claimant relies on board) | Bowen requires comparing OCI to all causes; thus applies here | Bowen does not apply; occupational-disease statutes differ and require broader comparison, but combined-condition statute is narrower. |
| Whether board erred by not including claimant’s preexisting AVN/fracture in the comparison | Board’s approach correct | Board should have included AVN/fracture contributions | Board correctly excluded non-PEC conditions (AVN/fracture where not statutory PEC) from the major-cause comparison; affirmed. |
