What to Write in the Remarks Section of Your SSDI Application

The remarks section of the SSDI application is one of the most overlooked parts of the entire process — and one of the most valuable. Most applicants either leave it blank or write a single vague sentence. That's a missed opportunity. Used well, this small text box can fill in gaps that the structured questions simply can't capture.

What the Remarks Section Is For

The Social Security Administration's application forms are built around checkboxes, dates, and structured fields. They're designed to collect consistent data efficiently — not to tell your story. The remarks section exists precisely for what falls outside those fields.

Think of it as a margin note to the reviewer: a place to explain something that a yes/no answer couldn't fully cover, clarify a date that looks unusual, or flag information that might otherwise be misread.

The Disability Determination Services (DDS) examiner reviewing your file is working through dozens of cases. Clear, specific notes in the remarks section reduce the chance that something important gets missed or misinterpreted.

What Kinds of Things Belong Here

Not everything needs a note — but several situations genuinely benefit from a brief explanation:

Gaps or inconsistencies in your work history If you stopped working suddenly, switched jobs, reduced hours, or had an unexplained gap in earnings, the remarks section is where you explain why. A gap that looks like a career choice might actually reflect the onset of your condition. That distinction matters enormously to DDS when they're determining your alleged onset date (AOD).

Conditions that fluctuate or have good days and bad days SSDI reviewers are trying to assess your Residual Functional Capacity (RFC) — what you can still do despite your impairments. Many conditions don't affect people the same way every day. If your symptoms are episodic, progressive, or vary significantly, saying so in the remarks section helps provide context that a checkbox can't convey.

Multiple conditions that interact The application asks about individual impairments, but sometimes it's the combination — not any single diagnosis — that drives your limitations. A brief note explaining how your conditions overlap or compound each other can help reviewers see the full picture.

Medications and side effects If your prescribed medications cause fatigue, cognitive impairment, dizziness, or other side effects that affect your ability to work, note that here. Side effects that limit functioning are legitimate RFC factors, but they won't appear on their own without you raising them.

Recent medical changes If your condition worsened recently, you had a new diagnosis, or you're awaiting a procedure or test, the remarks section is a reasonable place to flag that context — especially if the timing is close to your application date.

How to Write It: Tone and Length 📝

Keep it factual and specific. This is not the place for emotional appeals or lengthy narratives. DDS reviewers are looking for functional information — what you can and can't do, when things changed, and why.

A few practical guidelines:

• Be specific about limitations, not just diagnoses. "I can no longer stand for more than 10 minutes without severe pain" is more useful than "I have back problems."
• Use approximate dates when you can. "I reduced my hours in March 2022 because I could no longer manage a full shift" connects your work record to your medical history.
• Stay brief. Two to four clear sentences per issue is usually sufficient. The goal is to clarify, not to replace your medical records.
• Don't repeat what's already captured in the structured fields. Use the space for what wouldn't otherwise appear.

What the Remarks Section Cannot Do

It's important to understand what this section is — and isn't.

It is not a substitute for medical evidence. The SSA's decision will hinge on your medical records, treating physician notes, and any supporting documentation you provide. A well-written remark helps reviewers interpret that evidence correctly; it doesn't replace it.

It also does not carry the same weight at every stage. At the initial application and reconsideration levels, DDS examiners review your file, often without meeting you. If your case proceeds to an Administrative Law Judge (ALJ) hearing, you'll have the opportunity to give testimony directly — which carries different weight than written notes on a form. The remarks section matters most early in the process, before you have other opportunities to explain yourself.

How Different Claimants Use This Section Differently

The value of the remarks section varies depending on the claimant.

Someone with a single well-documented condition and a clean work history may have little to add. Their records speak clearly, and additional notes may be unnecessary.

Someone with a complex medical history, multiple impairments, an inconsistent work record, or a condition that's hard to observe — chronic pain, mental health conditions, autoimmune disorders — is far more likely to benefit from thoughtful remarks. These are precisely the cases where a reviewer's interpretation of ambiguous evidence can go either way.

Someone who stopped working well before applying, or who worked through significant impairment before finally stopping, may need the remarks section to explain the timeline and why the onset date they're claiming is accurate.

The right approach for your remarks section depends entirely on what your application would otherwise leave unexplained — and that's something only you can assess based on your own history, your records, and what gaps exist between the two.
