The denial letter arrives and the first reaction is panic. Your child's SSI or SSDI benefits have been denied, and you're not sure what happens next or whether you can fix it. The answer is yes, you can appeal, and the timeline starts now.

Social Security denies a significant percentage of initial applications. At age 18, when childhood SSI recipients are reevaluated under adult disability standards, 55.7% are initially found ineligible. That doesn't mean the case is over. It means you're entering the appeals process, which has four levels and specific deadlines at each one.

The 60-Day Deadline

You have 60 days from the date you receive the denial letter to file an appeal. Social Security assumes you received the letter five days after the date printed on it, so your deadline is 65 days from that date.

If you miss this window, your case closes and you must start over with a new application. That resets the clock completely, which can mean months or years without benefits. If you're close to the deadline and still gathering information, file the appeal anyway. You can submit additional documentation later.

The Four Levels of Appeal

The Social Security appeals process has four stages. Most cases do not reach the final level, but understanding the full structure helps you know where you are and what comes next.

1. Reconsideration

This is the first level. You request reconsideration within 60 days of the initial denial. A different Social Security employee reviews your case, including any new evidence you submit.

The approval rate at reconsideration is low, around 13%. This level is a desk review, not a hearing. The reviewer looks at your file, evaluates the medical evidence, and issues a decision. Most families proceed to the next level after reconsideration is denied.

2. Hearing Before an Administrative Law Judge

If reconsideration is denied, you can request a hearing. This is where the process shifts significantly. You appear before an administrative law judge (ALJ), present your case, and can bring witnesses, including medical experts.

The approval rate at the hearing level is approximately 47%. The difference from reconsideration is substantial: you can testify, present evidence in person, and respond to questions about your child's condition and limitations.

Wait times for hearings vary by region but average 12 to 18 months from the date you request the hearing. During this time you can continue submitting updated medical records and other documentation.

3. Appeals Council Review

If the ALJ denies your claim, you can request review by the Social Security Appeals Council. This is not a new hearing. The council reviews the ALJ's decision for legal or procedural errors.

The Appeals Council can affirm the denial, reverse it, or send the case back to the ALJ for another hearing. The approval rate at this level is around 13%, similar to reconsideration. Most cases that reach the Appeals Council are either denied or remanded.

4. Federal District Court

If the Appeals Council denies your request or affirms the ALJ's denial, you can file a lawsuit in federal district court. This requires an attorney. The court reviews whether Social Security followed the law and whether the decision was supported by substantial evidence.

Very few cases reach federal court. Most families either receive approval earlier in the process or decide not to continue.

What the Appeals Process Requires

At every level, your case depends on medical evidence. Social Security evaluates whether your child's condition meets the criteria in their Listing of Impairments (the Blue Book) or whether the condition is severe enough to prevent substantial gainful activity.

Medical Records

Gather every relevant medical record: evaluations, treatment notes, test results, specialist reports, therapy records, and educational assessments (IEPs, 504 plans, or neuropsychological testing). Social Security will request records from providers you list, but you can also submit them directly.

New evidence strengthens your case at any level. If your child's condition has worsened or new diagnoses have emerged since the initial application, include that documentation.

Function Reports

At the hearing level, function reports are critical. These describe how your child's disability affects daily activities: self-care, communication, mobility, social interaction, and ability to follow instructions. Teachers, therapists, and caregivers can provide these reports. Specific examples matter more than general statements.

Representative or Attorney

You are not required to have representation, but most families who reach the hearing level work with a disability attorney or advocate. These representatives work on contingency, which means they are paid a percentage of back pay (unpaid benefits from the date of application to approval) only if you win. The fee is capped at 25% of back pay or $7,200, whichever is less.

Attorneys handle procedural requirements, submit evidence, prepare you for the hearing, and cross-examine medical experts if Social Security brings them. At the reconsideration level, representation is less common. At the hearing level and beyond, it becomes standard.

Why Cases Are Denied

Understanding the most common reasons for denial helps you address them in your appeal.

Insufficient Medical Evidence

Social Security requires detailed, consistent medical documentation. A diagnosis alone is not enough. They need records showing the severity of the condition, how it limits function, and that it has lasted or is expected to last at least 12 months.

If your child sees a specialist infrequently or has gaps in treatment, that can weaken the case. Fill those gaps with updated evaluations before filing your appeal.

Condition Not Severe Enough

Social Security evaluates whether the condition significantly limits the ability to perform age-appropriate activities (for children) or work (for adults). If the examiner concludes that the condition is managed with treatment or does not limit function, the claim is denied.

This is where function reports become critical. Even if treatment helps, if your child still cannot perform daily activities or attend school without significant support, that needs to be documented with specific examples.

Income or Asset Limits (SSI Only)

SSI is a needs-based program with strict income and asset limits. For children under 18, parental income is "deemed" to count toward the child's eligibility. If your household income exceeds the limit, the claim is denied even if the medical evidence supports disability.

At age 18, parental deeming ends. Many young adults who were denied SSI as children become eligible once their parents' income is no longer counted. If your denial was based on income rather than medical evidence, reapply after your child turns 18.

Timelines and What to Expect

The reconsideration decision typically takes three to five months. If denied, you request a hearing, and the wait for that hearing averages 12 to 18 months, though some regions are faster or slower.

During the appeals process, benefits do not continue unless you specifically request "payment pending reconsideration" within 10 days of the denial. This option allows benefits to continue while reconsideration is pending, but if the reconsideration is denied, Social Security may request repayment of benefits paid during that time.

Most families do not choose this option because the risk of overpayment outweighs the benefit of a few months of continued payment. If your financial situation is urgent, consult with a benefits counselor before deciding.

What Happens After Approval

If your appeal is approved, benefits are paid retroactively from the date of application (for SSDI) or the date you became eligible (for SSI). This lump sum is called back pay. If you had a representative, their fee is deducted from this amount.

Ongoing monthly benefits resume immediately. For SSI, you must continue reporting income and asset changes to Social Security. For SSDI, benefits continue as long as the disability persists and your child does not exceed substantial gainful activity income limits.

Filing the Appeal

To request reconsideration, file Form SSA-561 (Request for Reconsideration) online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office. Submit any new medical evidence with the form.

To request a hearing after reconsideration is denied, file Form HA-501 (Request for Hearing by Administrative Law Judge). The same filing options apply.

Keep copies of everything you submit. If you mail documents, use certified mail with tracking. If you file online, save confirmation numbers.

The denial is not the end of the process. The appeals system exists because initial decisions are often incomplete or based on insufficient evidence. At each level, you have the opportunity to present a stronger case. The families who succeed are the ones who continue through the process and gather the documentation that proves the severity of the condition.
