Policy basis
ERISA 29 CFR 2560.503-1 for employer-sponsored group LTD; state insurance code for individual policies. Unum's Group Long Term Disability certificates set a 180-day appeal window and require Unum to decide within 45 days (with up to two 30-day extensions for matters beyond its control).

"Unum: 'If you disagree with the decision on your claim, you have the right to appeal. You have 180 days from the date you received the denial letter to submit your appeal in writing.'"
Common Unum denial reasons
- •Definition of disability not met (own-occupation vs. any-occupation transition at 24 months)
- •Insufficient objective medical evidence (imaging, EMG, neuropsych testing)
- •Pre-existing condition exclusion during the look-back period
- •Self-reported symptoms limitation (24-month cap on subjective conditions)
- •Failure to attend independent medical examination or functional capacity evaluation
Key policy points
- •Own-occupation definition typically applies for the first 24 months; after that Unum applies the any-gainful-occupation standard.
- •Unum must produce the full claim file free of charge on written request under 29 CFR 2560.503-1(h)(2)(iii).
- •Any new evidence Unum obtains during the appeal (surveillance video, IME, medical file review) must be shared with the claimant with a chance to respond before the final decision.
- •Unum was the subject of a 2005 multistate regulatory settlement (California, Massachusetts, Tennessee, New York and 44 other states) requiring reassessment of pre-2005 denials; the settlement standards for claim handling remain a useful benchmark.
Override strategy
Request the full claim file in writing on day 1 of the appeal window (Unum must produce it under 29 CFR 2560.503-1(h)(2)(iii)). Rebut each reviewer opinion with an attending-physician statement that directly cites the policy definition and quantifies functional limitation (lifting, standing, sitting, cognitive load, absenteeism). Add a vocational report if the any-occupation standard applies. If Unum used surveillance or a peer review, obtain that material and respond to it before the appeal decision — the ERISA regs require Unum to give you that chance.
Federal court remands and administrative reversals happen when the claimant develops objective functional evidence and responds in writing to every reviewer opinion Unum obtained. Unum's own 2005 regulatory settlement raised the internal review bar for pre-existing and subjective-symptom denials.
Evidence that overturns
- •Complete claim file (request in writing under 29 CFR 2560.503-1(h)(2)(iii))
- •Attending Physician Statement quantifying functional restrictions
- •Objective testing: MRI, EMG/NCS, cardiopulmonary exercise test, neuropsych battery, FCE
- •Vocational assessment if the any-occupation standard applies
- •Written response to any Unum-obtained IME, peer review, or surveillance report
- •Employer job description matching the policy's definition of your occupation
For non-ERISA individual disability policies, the state insurance code and the contract control — appeal windows can be as short as 60 days and lawsuits are not preceded by mandatory internal review.
How long do I have to appeal a Unum LTD denial?+
180 days from the date of the denial letter under ERISA 29 CFR 2560.503-1 for group employer plans. Missing this deadline forfeits the right to sue in federal court.
Where do I send a Unum LTD appeal?+
Unum, Attn: Appeals, P.O. Box 100158, Columbia, SC 29202-3158. The exact address is also printed on the denial letter — always confirm before mailing.
Why did Unum deny my LTD claim?+
The most common grounds are Definition of disability not met (own-occupation vs. any-occupation transition at 24 months); Insufficient objective medical evidence (imaging, EMG, neuropsych testing); Pre-existing condition exclusion during the look-back period. The exact ground is stated in the denial letter.
Can I get my Unum claim file?+
Yes. Under 29 CFR 2560.503-1(h)(2)(iii) the carrier must produce the full claim file — every reviewer physician report and vendor engagement — free of charge on written request. Request it on day 1 of the appeal window.
Does an SSDI award help my Unum LTD appeal?+
An SSDI award is not binding on Unum, but it is persuasive: SSA's medical determination is based on the same clinical record, and federal courts have criticized carriers that ignored an SSDI award while collecting the SSDI offset from the claimant.
Upload the denial letter. We'll request the full claim file from Unum, rebut each reviewer physician by name, and prepare the appeal within the ERISA 180-day window.
