Already Settled? You May Not Be Done

Most people assume that when a workers' compensation case closes, it is over.

Frequently it is. But there are five situations where a settled or awarded case still has real value left in it — and in every one of them, the worker is usually the last person to find out.

The deadline that governs most of this: five years from the date of injury. Not five years from the settlement, not from the last payment, not from the award. From the date of injury. If you are approaching that mark and your condition has worsened, it is worth a conversation this month rather than next year.

1. Your condition got worse — the petition to reopen

Labor Code § 5410 preserves the right to bring proceedings within five years of the date of injury on the ground that the original injury caused new and further disability.

What qualifies, under Applied Materials v. WCAB (2021), is a demonstrable change in your condition, including:

• a gradual increase in disability
• a recurrence of temporary disability
• a new need for medical treatment
• conversion of temporary disability into permanent disability
• a change in the treatment regimen

Two requirements defeat most petitions, and both are about timing:

The petition must be filed within five years of the date of injury. There is no extension for a late-discovered worsening.

And the worsening itself must have occurred inside that five-year window. You bear the burden of proving the demonstrable change happened before the five years ran. A petition cannot be used to keep a case open indefinitely for treatment and re-evaluation where nothing changed in time.

Filing on time preserves jurisdiction beyond the deadline — a petition filed within five years can be decided after it.

One thing you should know before filing. Section 5803 cuts both ways. The Board's power to increase an award is the same power that lets it diminish or terminate one, and § 5804 gives the defendant 30 days to file a counter-petition. A petition to reopen for increased permanent disability opens the door to a defense petition to reduce it. That is not a reason not to file — it is a reason to file with the medical evidence already in hand.

For cumulative trauma, the five years runs from the § 5412 date of injury, which can be materially later than your last day of exposure. That analysis is here.

2. SIBTF — and the law just changed

If you had a disability before your work injury — from any cause, work-related or not — and the combination is severe, you may have a claim against the Subsequent Injuries Benefits Trust Fund. It is a separate defendant with a separate obligation, and the recovery is frequently a life pension your employer never owed.

A SIBTF claim survives a Compromise and Release of the underlying case.

But two things have changed and both are urgent:

California rewrote the SIBTF statute in July 2026. SB 171 changed how the qualifying thresholds are measured, overruled the rule allowing multiple impairments to be added, barred workers already at 100% total disability, and created the fund's first statute of limitations — five years from the subsequent injury, or six months from resolution of permanent disability, whichever is later.

And pending claims are sorted by a June 1, 2026 procedural snapshot. The full analysis is here, and it is the most time-sensitive page on this site.

The screening question: did any doctor in your case apportion a substantial part of your disability to a pre-existing condition? If so, that report may be the foundation of a claim nobody told you about.

3. Your Medicare Set-Aside is not working

If your settlement included a Medicare Set-Aside, that money is restricted. It must be spent on injury-related treatment that Medicare would otherwise cover, at the appropriate rates, and it must be accounted for.

Problems surface years later, and they are serious:

The money ran out. What happens next depends on whether the account was administered properly and reported correctly. If it was, Medicare generally picks up thereafter. If it was not, it may not.

It was spent on the wrong things. Medicare can deny payment for injury-related care until the set-aside amount has been properly exhausted — which can mean paying out of pocket for treatment you thought was covered.

It was underfunded from the start. An allocation built on an optimistic projection of future care becomes a problem when the actual care costs more.

Nobody explained the accounting. Self-administration carries reporting obligations most people are never walked through.

Since April 2025, set-aside details are reported to CMS through mandatory insurer reporting, so the government now has visibility it did not previously have. If your set-aside is exhausted, nearly exhausted, or you are unsure whether it was administered correctly, get it looked at before you need the treatment.

4. Your award is not being paid

An award that is not being paid is a solvable problem, and the tools escalate.

The automatic 10%. Under LC § 4650(d), any late temporary or permanent disability payment is increased by 10% — no proof of unreasonableness required. It is supposed to be self-imposed without you asking. It frequently is not. Pull the payment ledger and check the dates.

Interest. Under LC § 5800, awards bear interest from the date of the award.

Penalties. Under LC § 5814, unreasonably delayed or refused compensation is increased by up to 25% or $10,000, whichever is less. Be realistic about this — the standard requires showing the delay was unreasonable, and a carrier with a genuine legal position usually defeats it. The strong cases are failure-to-investigate and failure-to-pay-what-was-ordered cases, not disputes about the law.

And the step most people never hear about: under LC § 5806, a workers' compensation award can be converted into a superior court judgment — which brings the enforcement machinery of the civil courts to bear, including collection remedies the WCAB does not have.

5. The systems nobody coordinated

Workers' compensation does not exist in isolation, and the interactions are where money quietly disappears.

Social Security Disability. SSDI benefits can be offset by workers' compensation payments. How the settlement was worded affects the size of that offset — settlement language spreading a lump sum over a life expectancy can materially reduce it. If your settlement was drafted without that in mind, the offset may be larger than it needed to be. This is worth checking even years later.

CalPERS and public retirement systems. Industrial disability retirement is a separate proceeding from the comp case, with its own standards and its own medical evidence — and decisions in one affect the other. For public safety workers especially, a large share of the real value sits here, and it is routinely handled by people who never speak to each other.

EDD. Liens and reimbursement obligations do not always get resolved cleanly at settlement.

Medicare conditional payments. Separate from any set-aside, and separately enforceable.

What to look at, in order

1. Find your date of injury and count five years. That single date governs the reopening right and much else.
2. Look at whether your condition has demonstrably changed — new treatment need, increased disability, a return of time off work — and when that change occurred.
3. Check your file for an apportionment finding to a pre-existing condition. That is the SIBTF screen.
4. If you have an MSA, check the balance and the administration.
5. Pull the payment ledger and check every payment date against when it was due.
6. If you receive SSDI or a disability retirement, have the interaction reviewed.
