Successful Appeal of Denial
Lyfu, Elementary School Teacher, Woodbury, Minnesota
Disability: Mental Illness, Anxiety, Depression, PTSD
Problem: An elementary school teacher and military veteran began having intense feelings of anxiety and depression. He sought treatment unsuccessfully for a few years, and ultimately had to stop working. He applied for Long Term Disability benefits so that he could seek adequate treatment without the stress of working. Despite his symptoms intensifying at work, the insurer wrote a letter denying him benefits and saying that he could return to work full-time.
Success – Overturn of Denial: Frustrated that Sun Life Financial seemed to ignore his symptoms, he contacted Fields Law for help with an appeal. The attorneys at Fields Law reviewed the medical records and found that Sun Life Financial ignored a key doctor’s report. Our attorneys called the doctor and had him write a letter supporting the appeal. Sun Life Financial overturned their decision, granting our client ongoing benefits and awarding him a lump-sum payment for back-pay. Our client is relieved to be able to focus totally on treatment and not his fight with Sun Life Financial.
Overturn of Denial
Carissa, Assistant Manager, Simpsonville, South Carolina
Disability: Fibromyalgia, Anxiety, Depression
Problem: An assistant manager at a large outlet store, Carissa handled everything from payroll, scheduling, to unloading shipments in the warehouse. But when she developed fibromyalgia, it exacerbated her depression and anxiety rendering her completely unable to work. She submitted a claim to her disability insurance carrier, who determined she was not disabled from her job.
Success – Claim Approved: Carissa found Fields Law Firm and hired us to file her Sun Life claim denial and challenge the wrongful denial. We secured a report from the client’s treating provider that outlined the difficulties she would have with her work as an assistant manager. Our attorneys assembled the medical information and filed an appeal with Sun Life Financial. After reviewing our client’s case, Sun Life Financial approved her claim.
Overturn of Denial
John, Foreman, Livingston, Texas
Disability: Diabetic Neuropathy, Back Pain
Problem: After John started having back pain and neuropathy in his legs and feet, he was diagnosed with diabetes and his doctor recommended back surgery. His symptoms were so severe they forced him to stop working. John applied for disability benefits through Sun Life Financial, but was denied based on an independent nurse’s opinion of his medical records.
Success – Overturn of Denial: Frustrated, John turned to Fields Law for help with his Sun Life disability appeal. Our attorneys reviewed the denial documents and determined that the nurse’s assessment of his condition missed many key items. Fields Law sent a strong appeal and ultimately Sun Life overturned the decision, granting John ongoing benefits and back-pay. Our client was relieved to have a steady income once more.
