SSDI and Workers' Comp in California: Can You Get Both?

How does the Social Security 80% offset rule work?

Social Security combines your monthly workers' comp with your SSDI benefit. If the total tops 80% of your average pre-injury earnings, Social Security trims SSDI to bring both under that cap.

Social Security uses something called your "average current earnings." This is usually your best earning year in the five years before your disability began. Social Security sets a ceiling at 80% of that number.

If SSDI plus workers' comp together go above that ceiling, Social Security reduces your SSDI. It does not touch your workers' comp. Here is a simple example:

Social Security recalculates this every month. When your workers' comp payments stop, your full SSDI resumes. Always report any change in your workers' comp income to Social Security right away.

California temporary disability pays two-thirds of your average weekly wage. In 2026, the minimum is $264.61 per week and the maximum is $1,764.11 per week. Under Labor Code 4656, temporary disability can last up to 104 weeks within five years of your injury. Those weekly payments count as income in the offset calculation.

The offset applies to temporary disability payments, permanent disability payments, and any lump-sum settlement. The type of payment matters less than the monthly amount Social Security counts. A large lump sum can do the most damage without the right settlement language.

Can a workers' comp settlement protect my SSDI from the offset?

Yes. A settlement that spreads the lump sum over your life expectancy lowers the monthly income Social Security counts. That smaller number means a smaller offset and more SSDI protected.

When you settle your workers' comp case, you typically get one check. Without protection, Social Security may treat the entire amount as income in the month it arrives. This can wipe out your SSDI for months or even years.

A "spread-out" clause prevents this. The settlement agreement states that the lump sum covers payments spread across your remaining life expectancy. Social Security then divides the total by the months in that life expectancy. The result is a small monthly income figure. A smaller monthly figure means a smaller offset.

Here is how the same $120,000 settlement looks with and without a spread-out clause:

This clause must be worded precisely. Social Security is strict. Vague or missing language may not be honored. Your attorney must include this wording before the workers' comp judge signs the settlement.

Settling also ends your employer's obligation to pay future medical costs. Under Labor Code 4600, your employer must cover 100% of injury-related treatment with no copay while your case remains open. Settlement ends that coverage. Think carefully before closing your case without understanding what you give up on the medical side.

What is the difference between SSDI and California SDI?

SSDI is a long-term federal program tied to Social Security work history. California SDI is a state short-term program funded by paycheck deductions, lasting up to 52 weeks.

Many injured workers confuse these two programs. They are entirely separate, with different rules, funding sources, and timelines.

California SDI does not trigger the federal 80% offset. However, workers' comp and SDI generally cannot pay for the same period at the same time. SDI is most useful during the waiting period before workers' comp starts, or for conditions not caused by work.

SSDI requires proof that you cannot do any substantial paid work. The condition must be expected to last at least 12 months or result in death. That bar is much higher than California workers' comp. Workers' comp only requires that a work injury caused your condition.

Many seriously injured workers qualify for both. If your injury leaves you permanently unable to return to your occupation, consider applying for SSDI while your workers' comp case is still open. The two application processes are independent. Filing for SSDI does not harm your workers' comp claim.

What is a Medicare set-aside and does my settlement need one?

A Medicare set-aside reserves a portion of your settlement for future injury-related medical costs. It protects Medicare's interest so Medicare keeps paying after your workers' comp case closes.

If you are on Medicare now, or expect to be within 30 months of your settlement, federal rules expect you to protect Medicare's interests. Ignoring this step can mean Medicare refuses to pay future bills tied to your injury.

A Medicare set-aside (MSA) is a separate account funded from your settlement. You use those funds first for any injury-related medical care after settlement. Once the MSA is spent correctly, Medicare resumes as your primary payer. The Centers for Medicare and Medicaid Services (CMS) has review thresholds. CMS review is generally triggered when your settlement exceeds $25,000 and you are already on Medicare, or exceeds $250,000 when Medicare enrollment is expected within 30 months.

Getting the MSA amount right matters. Too low, and you may be personally on the hook for future medical bills. Too high, and you reduce your net settlement without reason. An attorney working with an MSA specialist finds the right balance.

While your case is open, Labor Code 4600 guarantees full medical coverage at no cost to you. Settlement ends that coverage. Do not sign a settlement without understanding what you are giving up on the medical side and whether an MSA is needed to fill the gap.
