The claimant sought entitlement to IRBs from the date of denial until her return to work and various medical benefits, including a chronic pain assessment, and a two-part physiatrist assessment. Adjudicator Lake held that the claimant did not meet the IRBs test and both the chronic pain assessment and two-part physiatry assessment were not reasonable and necessary. The only evidence on the claimant’s essential tasks of pre-accident employment were from self-reports to medical professionals. There were no entries in medical records regarding her ability to work for the period in dispute. The insurer relied on three IE reports (psychology, neurology, orthopedic surgeon) which all concluded that the claimant did not suffer an inability to perform the essential tasks of her pre-accident employment. The adjudicator found the IE reports to be largely convincing accounts of the claimant’s post-accident condition. With regard to the disputed chronic pain assessment, the adjudicator preferred the two IE reports from the insurer which both found that the assessment was not reasonable and necessary. The adjudicator noted that the referring chiropractor did not make a finding as to whether the claimant’s alleged chronic pain occurred as a result of the accident, failed to comment on pre-accident migraines, and omitted details of pain levels and complaints, whereas one of the IE assessors was authorized to practice on chronic pain management. Additionally, there was no medical documentation on file beyond the assessment report from the referring chiropractor. With regard to the two-part physiatry assessment, there was conflicting evidence regarding the claimant’s impairments as she was able to return to work in a physical role, yet unable to complete ADLs involving her work tasks. The adjudicator also noted that the claimant did not pursue other recommended investigations, such as an MRI, to determine her physical status, which was one of the goals of the treatment plans.
